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.
How can you measure weather?
The document describes the 4 seasons and different types of weather. It notes that winter is cold so dark heavy clothes are worn, spring is warm as flowers bloom, summer is hot so light clothes and beaches are common, and autumn is cool as leaves fall from trees. Different weather phenomena are also outlined such as wind, rain, snow, sleet, hail, and how weather is measured with tools.
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.
Y2_How temperature affect matter?
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.
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.

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 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.

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.

ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptx
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
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.

Presented at June 6-7 Texas Alliance of Groundwater Districts Business MeetingApplied 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.
