Science involves observing the natural world, questioning observations, and experimenting to explain phenomena. The story describes how George de Mestral observed spiny seeds sticking to his clothes and dog, questioned what made them sticky, and discovered under a microscope that the seeds had tiny hooks. This led him to invent Velcro, a fastener using the principle of small hooks catching and releasing fibers.

Everyone Has a Superpower
The document discusses different topics related to developing one's unique abilities or "superpower". It encourages the reader to stop asking for permission and instead think differently like Einstein by using time efficiently. It suggests that everyone has abilities they may not realize and can create their own history by pursuing their talents rather than waiting for opportunities. The overall message is that extraordinary abilities can come from anywhere so the reader should identify their own strengths and put them to use.
Science - Topic 02: Plant Parts - branches and leaves
Green leaves perform photosynthesis using sunlight, carbon dioxide, and water to produce sugar for the plant. Leaves face towards the sun for photosynthesis. Leaves also help the plant breathe by taking in carbon dioxide from the air. Water and minerals are pulled from the roots up through the stem and branches and out the leaves. As plants grow, they produce more branches with leaves to gather more sunlight, food, and air without shading each other.
Science - Topic 01: Plant Parts - roots and stems
The document discusses the roles of roots and stems in plants. Roots anchor the plant in soil, take in water and nutrients which are transported through the stem. Roots come in different types like tap roots and fibrous roots. Stems support the leaves and transport water and nutrients between the roots and leaves. Stems in trees are called trunks which provide strength and stability.
week-1 grade 4-Presentation.pptx
The document is about what scientists do and how to become one. It defines science as the study of the natural world through observation and experimentation. A key part of being a scientist is carefully observing phenomena and writing down observations in notebooks or journals. The document also discusses how scientists perform experiments by making observations, asking questions, developing hypotheses and models, and following procedures. It notes that everyday activities like testing a pen can be experiments if done in a scientific way. Finally, the document states that the reader, too, can be considered a scientist if they make careful observations and write them down.
Energy-Lesson-1-Presentation on who is a scientis
A scientist is someone who observes the natural world systematically through experiments and written records of observations. The document outlines that science involves observing natural phenomena and testing hypotheses through experiments with controlled conditions and procedures. It emphasizes that the most important tool a scientist has is a notebook to record observations, as this allows them to join the scientific community. Finally, it states that anyone can be a scientist by performing everyday experiments and recording their observations.
Intro to Life Science & Biology

It discusses topics like the scientific method, cells, homeostasis, growth and development, reproduction, genetics, energy use, responding to the environment, and evolution. The document serves to outline foundational concepts for students beginning to study biology.
LECTURE 3 SPONTANEOUS GENERATION THEORY.pptx
This document discusses the spontaneous generation theory and biogenesis theory of microbial origins. It describes how early scientists like Francesco Redi, Lazzaro Spallanzani, and Louis Pasteur experimentally disproved the theory of spontaneous generation through controlled experiments. Redi showed that flies, not decaying meat, produced maggots. Spallanzani demonstrated that boiling broth killed microbes and they came from air, not from non-living matter. Pasteur's experiments with flasks proved microbes arose from pre-existing cells, supporting biogenesis over spontaneous generation. Through scientific investigation, these scientists established that life arises from pre-existing life, not non-living matter.

Happy accidents have led to many important discoveries and inventions throughout history. Christopher Columbus discovered the New World by accident when he was trying to find a new route to Asia. The first antibiotic, penicillin, was discovered by accident when Alexander Fleming noticed a mold had dissolved bacteria in one of his lab dishes. Velcro was invented when a hiker noticed how plant burrs clung to his clothes and got the idea to replicate their mechanism in a fastener. Post-it Notes were created when an adhesive that was considered a failure was found to be perfect for holding paper scraps in place temporarily. These stories show that mistakes and accidents are not always bad and that valuable innovations can arise from closer examination of apparent failures.
The great fossil find!
1. Students play the role of paleontologists and uncover fossil bones over the course of 3 days.
2. They assemble the bones each night in their camp and consult additional resources to identify the animal.
3. On the final day, with all bones assembled and after consulting skeleton drawings from other sites and resources, the students determine the identity of the animal and revise their understanding.
What is Science.ppt
This document provides an introduction to the field of science. It explains that science involves making careful observations of the natural world and conducting investigations to understand natural phenomena. Scientists observe using their senses, compare similarities and differences, think critically about their results, and collect evidence to explain their observations. An example is given of Francesco Redi's experiment which showed that flies, not spontaneous generation, caused maggots to form. The document stresses that scientists draw conclusions based on evidence from repeated experiments, not opinions, and that scientific knowledge advances as findings are shared and built upon.
Unit 1 Science (Glencoe Red 2002)
The document summarizes how scientific methods were used to solve a problem at a veterinary clinic.
1) A veterinary technician noticed that two cats boarding at the clinic were scratching and developing skin sores. She wanted to determine what was causing the irritation.
2) She gathered information by observing the cats' behavior and contacting their owner. She formed a hypothesis that something in the cats' litter was irritating their skin.
3) She tested her hypothesis by conducting an experiment where she gave one cat litter with deodorant (the control) and the other litter without deodorant (the experimental). She analyzed the data and found the experimental cat's sores healed while the control cat's
Science Introduction
Science is the organized study of the natural world through observation and experimentation. There are four main branches of science: chemistry, physics, earth science, and life science. The scientific method is used to study science and involves identifying a problem, gathering information, forming a hypothesis, testing the hypothesis through experiments, analyzing results, and drawing a conclusion. Key parts of an experiment include a control and variables. Scientific theories are explanations of observations that can change over time with new evidence, while scientific laws are statements that are always true.

The making of a scientist.pptx
- Richard H. Ebright grew up in Pennsylvania where he developed a strong interest in science from a young age through collecting insects and conducting experiments. He conducted pioneering research starting in his youth on monarch butterflies that helped uncover an unknown insect hormone and laid the foundations for his future career in science. His extensive research as a young teenager won him top prizes in multiple science fairs and led to opportunities to conduct studies at university laboratories.
The making of a scientist.pdf
Richard H. Ebright showed early talent and interest in science as a child by collecting rocks, fossils, and coins. He also collected 25 species of butterflies by the age of 8. His mother encouraged his interest in science by taking him on trips and buying him microscopes and other scientific materials. A book about butterfly migration called "The Travels of Monarch X" sparked his fascination with butterflies and their life cycles. As a teenager, Ebright conducted experiments on frog tissues, viral diseases in monarch caterpillars, and mimicry in viceroy butterflies that won science fairs. His high school project on the function of gold spots on monarch pupae led to success at an international science fair.

1) Create your own craters by dropping a bouncy ball into a baking dish filled with flour to observe crater formation.
2) Make an out-of-this-world solar system project by creating planet models on skewers placed at scaled distances on a field.
3) Conduct meteoroid experiments including measuring and comparing craters made by dropping objects. The activities aim to teach kids about space science concepts like asteroids, meteors and planetary orbits in a hands-on way.
Unit 1 lesson 1 What is Science
The document discusses the key aspects of science. It explains that science involves careful observation and investigation of the natural world. Scientists perform investigations using the scientific method to study phenomena and gather evidence. Evidence can be direct or indirect. The document also outlines how scientific knowledge grows as scientists communicate their findings and build upon one another's work through repeated experimentation.
Writing Spiders
The student noticed a writing spider living in her backyard near the house and fence. Writing spiders are commonly called black and yellow garden spiders or corn spiders. They weave intricate webs and are called writing spiders because their webs look like scribbles. While the spider was in her yard, the student had questions about its scientific name, why they are called writing spiders, where they can be found, if they are poisonous, and what they eat.
P2.2 Scientific Methods
Scientists use scientific methods to systematically investigate the natural world. The steps include asking questions, developing hypotheses, conducting experiments and observations to gather data, analyzing the results, drawing conclusions, and communicating findings. Paleontologist David Gillette used these methods to discover and name a new species of dinosaur, Seismosaurus hallorum, after questioning what type of dinosaur bones he discovered and testing his hypothesis that they were from an unknown species.
Parasite Otodectes cynotis in Kota Bharu
This document summarizes a student's mini project on ear mites in stray cats in Kota Bharu, Malaysia. The student collected 34 ear samples from stray cats in 4 different areas and found 7 samples positive for Otodectes cynotis mites under the microscope. The project objectives of determining mite presence in cat ears and comparing mite species in different areas were achieved. The highest number of positive samples came from the RTC Tunjung area. The document discusses ear mite lifecycles, symptoms, and treatment options.
UNIT ONE- Structures of Survival.pptx
This document outlines lessons from a science unit on plant structures and survival. It discusses communicating science lab safety rules, observing the external structures of plants, and investigating how specific carnivorous plants capture and digest prey. The lessons involve students working in groups to draw and act out safety rules, make observations of flower parts, and research facts about assigned carnivorous plants to argue which is best at catching prey.

- The steps scientists take in conducting research, including making observations, asking questions, developing hypotheses, making predictions, experimentation, analysis, and drawing conclusions.
- The differences between deductive and inductive reasoning, and how the scientific method uses hypothetico-deductive reasoning to formulate and test hypotheses.
- Key aspects of hypotheses like being testable explanations, having multiple alternatives, and being falsifiable but not provable. The progression from
Ch1 S1 Science and Scientists
The document provides an overview of science and scientists. It describes three methods of scientific investigation: research, observation, and experimentation. It discusses how science helps save lives, resources, and the environment. The document also lists some examples of scientists and their fields, including meteorologists, geochemists, ecologists, volcanologists, and science illustrators.
Cell theory power point 2
This document provides an overview of cell theory and the key differences between prokaryotic and eukaryotic cells. It discusses how cell theory was developed through the early observations and experiments of scientists like Hooke, Redi, Schleiden, Schwann, and Virechow. The three main principles of cell theory are introduced: 1) All organisms are made of one or more cells, 2) The cell is the basic unit of life, and 3) All cells come from preexisting cells. Prokaryotic cells are described as smaller, simpler cells without nuclei or membrane-bound organelles, like bacteria. Eukaryotic cells are larger, more complex cells that have nuclei and membrane-bound organelles
Science - Topic 04: Germination and growth
The document discusses the process of germination and growth in plants. It explains that seeds planted in soil will germinate by growing roots down and a stem up with leaves growing from the stem. For growth, young plants need light, water, and space. Some plants thrive in warm weather while others can grow in colder climates, so farmers must choose crops suited to their local conditions.
Science - Topic 03: Looking at flowers
Flowers have many parts and play an important role in plant reproduction. They grow when the plant is ready to reproduce. The reproductive process includes pollination, where pollen is transferred between flowers by insects or other animals, fertilization of the ovules, and fruiting, where the ovary develops into a fruit protecting the seeds. Flowers produce nectar to attract pollinators like bees which pick up pollen that is transferred to other flowers, allowing reproduction.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsAuthoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
