This document provides information about revisions made to a science textbook and guidelines for its use. It expresses gratitude for feedback and notes that science concepts may change over time. It encourages active, hands-on learning through low-cost activities and experiments using locally available materials. Activities are categorized as individual, group-based, or teacher-demonstrated. "More to know" sections provide extra facts for interest rather than testing. Evaluation focuses on understanding rather than rote learning, with room for open-ended answers and critical thinking. Suggestions for improvement are welcomed.
Module 4a life_science
This document provides guidance on teaching life science concepts to elementary students. It emphasizes keeping students excited about science, encouraging curiosity, and avoiding misconceptions. Key themes to teach include inquiry, patterns, systems, cycles of constancy and change, and structure and function. Students should learn inquiry skills like observation, classification, and experimentation. Content should include living vs. non-living things, life cycles, habitats, adaptations, and inheritance. The document also discusses teaching patterns, cycles, systems, and structure and function in depth.
Classifying organisms part 1 (1)
Organisms are anything that is living, such as plants, animals, and bacteria. We classify organisms into groups based on their characteristics and structures. We can classify all living things into two main groups - those with a backbone and those without. Vertebrates can be further classified into mammals, fish, amphibians, reptiles, and birds based on their structures. The document encourages exploring examples of different organisms and how they are classified.
Level 5 Subjects within the Curriculum Session 2
This document provides guidance for investigating living organisms, particularly plants, in a primary classroom setting. It discusses the importance of making detailed observations and considering children's existing knowledge. A variety of scientific inquiry methods are presented, such as exploring phenomena over time, identifying and classifying, and identifying and controlling variables. Specific guidance is given on encouraging observations of plants and leaves, using classification keys, investigating seed dispersal and plant structures. The relationships between plants and animals and how they depend on each other are also addressed. National curriculum standards related to living things and their habitats are referenced.
Lesson Plan and Worksheets on Characteristics of Living Lhings
The document outlines a lesson plan on the characteristics of living things. It includes 7 key characteristics: movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. The plan involves introducing these characteristics, having students identify them in groups, filling out a mind map and worksheets, and discussing each characteristic in more detail. The goal is for students to understand what qualifies something as living and be able to differentiate living and non-living things.

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
Living beings processes
This document defines and compares living and non-living things. It states that all living things have cells, grow and change, reproduce, respond to stimuli, exchange gases, take in energy and get rid of waste. Examples of living things include plants, animals and humans. Non-living things do not have these life processes and are made of materials like rocks, water or plastic. The document emphasizes the importance of understanding and preserving life in nature.

This document contains the daily lesson plans and objectives for a middle school science unit on plant and animal cells. Over the course of five days, students will learn to identify parts of animal cells, describe animal cell organelles, differentiate between plant and animal cells, and distinguish their key characteristics and differences. Activities include labeling diagrams of cells, answering questions about organelle functions, comparing cells through a graphic organizer and Venn diagram, and creating a mini-poster comparing plant and animal cells. The unit aims to teach students the basic structures and functions of plant and animal cells.
Plant crash course - introduction to plant evolution
The document provides information about plant anatomy and classification. It discusses the basic plant organs of roots, stems, and leaves and their functions of absorbing water/minerals, providing height, and performing photosynthesis. Plants are classified as nonvascular, seedless vascular, or seed vascular. Seed plants are further divided into gymnosperms like conifers, which have naked seeds on cones, and angiosperms or flowering plants, which have flowers, fruits, and enclosed seeds. Angiosperms represent the most evolved and diverse group of plants. The document also describes plant reproduction structures like flowers and their parts, as well as seeds and fruits.
The plant kingdom
Plants are living things. Difference between trees, bushes and grass. Deciduous and evergreen trees. Wild and cultivated plants. Why are plants important for us? Plant reproduction. Pollination. Non-flowering plants and fungi.
Honeybees
Here are 3 sentences using "as...as" with adverbs:
1. She knows that song as well as you do.
2. George works as quietly as the rest of the class does.
3. I don't visit my grandparents as often as I should.
Open science and 21st century naturalist skills
This document outlines a curriculum for developing 21st century naturalist skills in students. The curriculum aims to awaken students' interest in the natural world by focusing on field work methodologies like observation, documentation, classification and inquiry-based problem solving of local natural issues. It provides guiding questions for student inquiries on topics like natural history, observations, species classification and connections in nature. It also outlines basic principles, general skills, methodological skills and habits of mind needed for naturalist work. Finally, it discusses using content standards and providing tools to support students' naturalist studies. The overall goal is to allow students to pursue interests in nature through hands-on field investigations.
Plant responses
Plant shoots bend towards light sources due to the plant hormone auxin. Experiments by Charles Darwin, his son Francis Darwin, and later Peter Boysen-Jensen and F.W. Went showed that the shoot tip perceives light and communicates with the rest of the shoot chemically to cause bending. Went eventually isolated the hormone auxin, which causes differential cell growth on the light and dark sides of shoots and roots, resulting in phototropism and gravitropism. Auxin also influences other growth processes like apical dominance, rooting of cuttings, and fruit development. Gibberellins and cytokinins were also later identified as important plant growth hormones.
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.
UoI Plants and mealworms 12-13
This document summarizes experiments conducted by children to understand the requirements of living things, specifically plants. [1] The children explored various items to discover the central idea that living things require special conditions to grow and be healthy. [2] They conducted experiments with plants and colored water which showed that water is absorbed by the roots and travels up the inside of plants. [3] The children planned and wrote up their experiments, concluding that plants generally need soil, water, air, and light to remain healthy.
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.
Nature of science and evolution
The document provides instructions for students to complete various classroom activities related to evolution, including a Venn diagram comparing mitosis and meiosis, defining science, completing surveys on the nature of science and evolution, modeling natural selection through an activity, and taking notes on key concepts like natural selection, fitness, and evidence for evolution such as homologous structures.

The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
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.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

- 2. STATEME NT I can communicate rules that should be followed as a scientist.
- 3. • We are going to look at our Science Safety rules! • You will work in groups and each group will be assigned a rule • You will draw the rule being followed on a poster • Then your group will make up a Short skit play to act out an example of NOT FOLLOWING the rule and an example of following the rule • You will be presenting so make sure you practice!
- 5. • What other science safety rules could be added to this list? • Work together as a group to add some more safety rules to the list!
- 6. DAY 2 Lesson 2: How do structures of plants help them survive in their habitats?
- 7. STATEME NT I can observe the external structures of a plant and generate questions about them.
- 8. I went to the grocery store yesterday and wandered through the product section. I noticed all sorts of plants for sale. Some of them we eat, like fruits and veggies. But I was looking for flowers to take to my mother when I pick her up to take her out for her birthday dinner. I stopped and picked up a few bunches.
- 9. Why do flowers have different parts?
- 10. • I am going to show each group a flower • You will want to look closely and touch it carefully! • You will make observations of the parts of the whole flower in your journal or notebook. • Share your observations or traits with the group • Create a list of what you all had in common? • Create a list of questions your group has about the parts of the flower!
- 11. Flowers have many parts including stems, leaves, and petals. Petals are usually brightly colored and different flowers have different shaped and colored petals.
- 12. • Why do flowers have petals? • What are all of the small parts within the flower? • Why are leaves green?
- 13. How do the structures of plants help them survive in their habitats? LESSON 3:
