The document describes the different types of weather and seasons. It discusses how the temperature changes between hot summers when it's warm enough to go to the beach and cold winters when heavy clothes are needed. Spring is warm and the flowers bloom, while autumn is cool as the leaves fall from the trees. Various types of precipitation are also outlined such as rain, snow, sleet and hail.
Weather
This document defines key weather and climate terms like weather, the water cycle, evaporation, water vapor, temperature, and cloud types. It also asks questions about identifying the season based on environmental cues like trees budding, flowers blooming, visiting the beach, leaves falling, and snow falling.
Global Climate
This document discusses the difference between weather and climate and some key factors that influence climate, including ocean currents, wind currents, elevation, latitude, and landforms. Weather is short-term while climate considers conditions over the long-term. Factors like proximity to oceans, elevation, and latitude determine whether a location will be generally hotter or colder. Landforms can also impact climate by blocking or redirecting wind and rain patterns.
Earth's climates
The document outlines Earth's main climates, including hot/torrid climates near the equator with high temperatures and precipitation year-round, temperate climates that are tropical with rain in summer or oceanic/Mediterranean with precipitation patterns, cold/frigid polar climates with very low temperatures and little snow, and mountain climates with colder temperatures and more precipitation at higher altitudes.
Where does Soil come from?
Soil is formed over long periods of time from the breakdown of rocks and dead plants and animals into smaller particles. These particles are decomposed by organisms into nutrients that make up soil. Soil texture and composition can vary depending on the size of particles, which range from very small clay to larger sand, with silt and loam mixtures draining water at different rates.
What is sound
Sound is important because it tells us things, helps us stay safe, and can help us wake up. Sound is caused by vibration, which is the movement back and forth. Sounds can have different volumes, being either loud or soft, and different pitches, being either high or low. The document discusses what sound is, why it is important, how vibration causes it, and that sounds can have different volumes and pitches.
Rocks 2018
Rocks are a non-living natural resource that come in different sizes, shapes, and colors and have been used as tools for thousands of years. Some examples of rocks and their uses include chalk for making chalk, marble for making statues, slate for making roof tiles, limestone for making cement, and granite for making kitchen tables. Other rocks like graphite are used for pencils, magnetite for magnets, fluorite for toothpaste, and turquoise for jewelry.

How does earth's motion cause day and night?
The Earth's rotation on its axis causes day and night. As the Earth spins, one side constantly faces the sun and experiences day while the other side faces away from the sun and experiences night. This rotation takes place every 24 hours, with each rotation constituting a full day and night cycle. The apparent movement of the sun and moon is actually due to the Earth's rotation, not their movement.
What can change how things move?
Force is the power that helps us move things. There are two types of forces: push forces and pull forces. Push forces move objects away while pull forces move objects towards the thing applying the force.
How do you describe motion?
Motion is defined as a change in an object's place or position. There are three main types of motion: straight motion where an object moves in a straight line, circular motion where an object moves in a circular path, and zigzag motion where an object moves back and forth in an irregular pattern. Examples are given for each type of motion including marching ants and soldiers, fan blades and clock hands, and rollercoasters.
Electricity
Electricity is important in powering many devices in homes and making them more convenient. It comes from power plants and is delivered to homes through outlets. Without electricity, many modern conveniences like lights, appliances, and electronics would not function. Electricity can power devices directly from outlets or through batteries and can be converted into different forms of energy like heat, light, sound, and motion to operate machines. Proper safety rules must be followed when using electricity.
Y2_Electricity
Electricity is important in our lives and powers many devices in our homes. If the electricity went out this morning, it would be difficult to function without devices like lights, appliances, and electronics. Electricity comes from power plants and is delivered to homes through wires, where it can power devices plugged into outlets on walls or run on batteries. Electricity can be converted into different forms of energy like heat, light, sound, and motion to power various machines and devices. Proper safety around electricity is important.
Y2 2018_How temperature changes matter
Melting involves changing a solid into a liquid state using heat. Boiling changes a liquid into a gas (water vapor) when heat is applied, while freezing is the reverse process of changing liquid to solid with cooling. Condensation occurs when a gas hits a cold surface and changes back to a liquid state. These changes of state between solid, liquid, and gas are known as melting, freezing, boiling, evaporation, and condensation.

Melting involves changing a solid into a liquid state using heat. Boiling changes a liquid into a gas (water vapor) with heat, while freezing is the reverse process of changing liquid to solid with cooling. Condensation occurs when a gas changes to a liquid state by contacting a cold surface, such as water vapor condensing to liquid water on the outside of a cold drink. These changes of state between solid, liquid, and gas are caused by the addition or removal of heat from the substance.
W4 (21 1 24-1) plant parts
The document discusses plant parts and how plants grow. It lists the main plant parts as roots, stem, leaves, and flowers. Roots take in water and nutrients from the soil, the stem holds up the plant and transports water and nutrients, leaves produce food for the plant through photosynthesis, and flowers are involved in reproduction. It then outlines the basic stages of plant growth, starting from a seed where a root emerges followed by a stem and leaves as the whole plant develops.
Matter Year 2
This document discusses the three states of matter - solid, liquid, and gas - and describes their key properties. It also distinguishes between physical changes, like cutting, bending, and freezing, which alter the shape or form of matter but not its chemical composition, and chemical changes like heating, rusting, and burning, which produce new substances.
Matter
This document discusses the different states of matter - solid, liquid, and gas - and the physical and chemical changes that can occur to matter. Physical changes include cutting, bending, squashing, twisting, stretching, and freezing, which change the shape or form of matter but not its chemical makeup. Chemical changes, such as heating, rusting, and burning, involve changes to the chemical composition of matter.
Living & non living things
This document discusses the differences between living and non-living things. It asks a series of questions to help determine whether something needs air, water, food, can grow and change, move, and occupy space in order to establish if it is living or non-living. Examples of a living thing that is discussed is a fish, while characteristics of both living and non-living things are listed to aid in the comparison.
W1 lab tools balance,thermometer and dropper
Lab tools are used to make colorful cupcakes and measure ingredients. A dropper is used to add food coloring to cake mixtures. A thermometer measures temperature and can be used to check if someone has a fever. A balance measures weight and can measure how much sugar to add to cake batter. Making jelly requires using different tools - a balance to measure powder, a thermometer to check liquid temperature, a dropper to add food coloring, and following steps of mixing, cooling, and molding the jelly.
lab safety rules
We want you to stay safe in the lab by following these rules: do not eat, drink, play or run; do not touch anything hot; wear goggles and lab coats to protect your eyes and body, and wear gloves to protect your hands.
W12 lab tools
This document provides instructions for using common lab tools like goggles, measuring cups, measuring tapes, magnifying lenses, and forceps. It describes what each tool is used for, like using goggles to protect eyes, a measuring cup to measure liquids, a measuring tape to measure length or height, a magnifying lens to make things look bigger, and forceps to help separate items. It also includes examples of using the tools, such as measuring 40ml of liquid, measuring a colleague's height as 3cm, using forceps to pick up paper and a magnifying lens to read it.
Hydraulic pressure
This document discusses using water pressure and hydraulics to move objects. It introduces the concept of a hydraulic system using two syringes connected by a tube, where squeezing one syringe causes the other to move due to water pressure transfer through the tube. The document suggests applying the scientific method to test if water can be used to move things.
Epic rocket
Rocket flight is powered by chemical reactions in the fuel that produce gases. The document discusses how rockets use fuel that undergoes chemical changes to produce carbon dioxide gas, building pressure and allowing the rocket to fly. It also asks if varying the amount of vinegar in a baking soda and vinegar rocket reaction would affect how high the rocket flies, suggesting applying the scientific method to test this.
Walking water
Water can move upwards against gravity through thin tubes due to capillary action, where water molecules are attracted to the sides of the tube and to each other, causing water to rise in narrow spaces. Capillary action allows water to travel through thin spaces like plant stems without the need for pipes.
Magic slime
This document describes how to make magic slime move without touching it using magnets and iron fillings. Magnets have north and south poles that attract unlike poles and repel like poles, allowing magnetic objects like iron fillings mixed in slime to move when a magnet is brought near without direct contact. The scientific method is applied to demonstrate this magnetic attraction and repulsion.
Y1 w7 (22 10 26-10) scientific method
The document describes the scientific method using the example of discovering which colors make green. It outlines the steps of the scientific method: observe, ask questions, make a hypothesis/prediction, experiment, and reach a conclusion. The experiment involves mixing blue and yellow color samples in measuring cups to test if they make green, following the scientific process to think like a scientist.
W6 (15 10 19-10) enquiry skills_Scientific method
Scientists follow a process of observation, hypothesis formation, experimentation, and conclusion to think like scientists. This involves first observing a phenomenon, then asking questions and making an educated guess or hypothesis about it, following up by designing and conducting an experiment to test the hypothesis, and finally analyzing the results to draw a conclusion.
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.

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.

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.
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.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
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.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
