Measuring distance
People originally used parts of their own body to measure distance, such as feet, elbows, and fingers. Over time, standardized units were developed, including the cubit, span, and yard. Today, the standard unit for measuring distance is the meter. Other common units include centimeters, millimeters, and kilometers which are related by factors of 10, 100, and 1000. Common tools for measuring length include rulers, tape measures, micrometers, odometers, and advanced technologies like satellites and laser range finders.
Science 5 Quarter 3 Week 1
The document discusses concepts related to motion, including reference point, distance, speed, and force. It defines reference point as a fixed place or object used to determine an object's position. Distance is defined as the measure of how far or near two points are from one another. Speed is calculated by dividing the distance covered by an object by the time it took to cover that distance. Motion is described as a change in position relative to a reference point, and can involve the application of force through a push or pull. Examples are provided to demonstrate calculating speed using distance and time.
Measurement
This document provides information about different units of measurement for time, length, area, capacity/volume, and weight. It defines common units like seconds, minutes, hours, meters, centimeters, liters, milliliters, ounces, pounds, and kilograms. It also explains how to read analog clocks, use rulers to measure length, and properly measure liquids and other items using measuring cups. Concepts covered include significant figures, prefixes like kilo and milli, and converting between metric and U.S. customary units.
Fair tests
The document discusses the key variables in a fair experiment: the independent variable that is changed, the dependent variable that is measured as a result, and the control variables that are kept the same. Specifically:
- The independent variable is what is deliberately changed, such as the amount of water given to plants.
- The dependent variable is what is measured as a result of changing the independent variable, such as the growth of the plants.
- Control variables are kept the same between trials, like the amount of sunlight, type of pot, and potting mix used for the plants.
Friction (6)
This document discusses friction, including its definition as a force that opposes the relative motion between two surfaces in contact. It describes different types of friction like sliding friction, static friction, fluid friction, and rolling friction. It also discusses factors that influence friction like surface texture, lubricants, and how friction can be both advantageous and disadvantageous. For example, friction allows us to walk and grip objects but also leads to wear and reduces machine efficiency by converting mechanical energy to heat.
Forces and their effects pps
Forces can make objects move, change speed or direction, or deform shape. A force is measured in Newtons and can be exerted through contact or non-contact. Contact forces include tension, strain, and impact forces. Non-contact forces include magnetic, electrostatic, and gravitational forces. Magnetic forces involve attraction or repulsion between poles, while gravitational forces act between all masses and decrease with distance.

The importance of measurement
Measurement is a fundamental concept in science that allows scientists to conduct experiments and form theories. It involves comparing properties of an object to a standard unit of measurement. The metric system, also known as the SI system, provides standardized units that are used worldwide. The seven base SI units are used to derive other common units like liters, newtons, and joules. Measurement tools introduce uncertainty, so scientists aim for accuracy and precision by taking multiple measurements and calculating averages.

It includes review questions, examples, group activities, and explanations of key concepts. The goal is to teach students to use appropriate measurement tools and standard units accurately, describe motion by changes in an object's position over time, and calculate an object's speed by dividing its distance traveled by the time taken. Accurate measurement, standardized units, and understanding motion and speed are important for processing data correctly and preventing accidents.
01 Chapter Notes
1. The document discusses the process of science and how scientists investigate problems. It describes the steps scientists take to define problems, design research to study problems through observation or experimentation, analyze data, and communicate conclusions.
2. Descriptive research and experimental research design are two methods used to answer scientific questions. Descriptive research relies on observation while experimental research tests hypotheses through controlled experiments.
3. When investigating problems, scientists must clearly define the problem and research objective, use unbiased methods, carefully collect and record data, analyze results, and report conclusions. Models and standardized measurement systems help scientists communicate and compare findings.

What is a star
1) Stars appear as points of light because they are very far away from Earth, even stars within our own galaxy like Andromeda.
2) Stars are giant balls of hot, glowing gases that produce light and energy through nuclear fusion at their cores.
3) The brightness of stars is determined by their temperature, size, and distance from Earth, with brighter stars being hotter, larger, or closer.
Weathering and erosion
Weathering is the breakdown of rocks into smaller pieces through various processes like plant growth, water, freezing and thawing. Erosion is the movement of weathered material from one location to another by forces like water, wind, glaciers and gravity. Deposition is the placement of eroded pieces of Earth's surface in a new location, like sand dunes formed by wind or new islands created from sediment deposited by rivers in the ocean. Over time, weathering, erosion and deposition break down bedrock into soil and shape the landforms on Earth's surface.
Weather and climate
This document discusses weather and climate. It defines weather as the current conditions of the atmosphere at a specific time and place, while climate is the pattern of weather conditions over many years. The document outlines several factors that affect climate, such as sunlight, oceans, mountains, and altitude. It also describes tools that scientists use to measure and study weather conditions like temperature, wind speed and direction, humidity, air pressure, and rainfall.
Water cycle
The document discusses the water cycle, where water is constantly circulating around Earth in different forms. It explains that water evaporates from the surface into the air, condenses to form clouds, and falls back to Earth as precipitation like rain or snow. Most water is stored in oceans, but some is stored in groundwater, lakes, streams, and other bodies of water before starting to evaporate again.
The moon
The moon revolves around Earth once every 27 days, keeping the same side facing Earth. It reflects sunlight and its illuminated half changes shape in a cycle from new moon to first quarter to full moon to third quarter over 291⁄2 days. The moon is the closest celestial object to Earth at 384,000 km away. It has many impact craters and temperature extremes ranging from 127°C during the day to -173°C at night. Telescopes allow observation of details on the moon's surface.
States of matter
States of matter can exist in three forms - solid, liquid, or gas - depending on how close together or far apart the particles that make up all matter are from one another. All matter is composed of tiny particles too small to see. The arrangement and movement of these particles determine whether a substance is a solid, liquid or gas.
Solar system
The document provides information about the solar system. It describes the 8 planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. It explains that planets orbit the sun, with Earth being one of 8 planets in our solar system that revolve around the sun. The planets are divided into inner and outer planets, with the inner planets being rocky and closer to the sun, and the outer planets being gas giants farther from the sun.
The soil
Soil is the layer of loose material on Earth's land surface and is made up of particles of rock, air, water, and humus. Soil is organized into layers with topsoil at the surface containing the most humus and nutrients for plant growth, subsoil below it containing some humus and rock particles, and bedrock forming the bottom layer underneath. Soil types vary depending on the amounts of sand, silt, and clay particles in them, with loam being an ideal mixture supporting plant growth.
Plants use roots and stems
Roots take in water and nutrients from the soil to support the growth and survival of the plant. There are two main types of roots: taproots, such as carrots, that grow deep into the soil, and fibrous roots, such as grass, that spread out widely in many directions near the surface. Stems transport water and nutrients from the roots to the leaves and food from the leaves to the roots and stems. They also hold up and support leaves, flowers, and fruits. Stems come in different shapes and sizes depending on the plant, such as thick cactus stems that store water.
Plants use leaves to make food
Plants use their leaves to photosynthesize and produce food from sunlight, carbon dioxide, and water. Leaves help plants by absorbing sunlight to fuel photosynthesis, taking in carbon dioxide from the air, and regulating the plant's water levels through tiny holes on their surface. Leaves also protect plants by deterring predators through poison, sharp edges, or tough textures, and some leaves have waxy coatings or fuzz that help retain water in dry environments.
Plants use flowers or cones to reproduce
Plants reproduce using flowers, which produce seeds through pollination, or cones, which produce seeds through pollen blown from small pollen cones to large seed cones. Seeds contain genetic information from the parent plant and food to grow into a new plant like the parent. New plants grow from seeds through germination, where seeds sprout leaves and roots when conditions are right, allowing the cycle to continue as the new plants also produce flowers or cones.
Offspring like their parents
Offspring often resemble their parents physically due to inherited traits. Young animals may look similar to parents but also differ in some ways, like antelope which have smaller horns than parents. Traits can help offspring survive in their environment. Small differences in traits between offspring of the same species can impact their ability to survive, like coat color variations in mice that make some more visible to predators than others.
Minerals and rocks
Minerals and rocks are natural, non-living materials. Minerals are the building blocks of rocks and give rocks their properties. There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled lava or magma underground or at the Earth's surface. Sedimentary rocks form from compressed and cemented sediments over millions of years. Metamorphic rocks were originally igneous or sedimentary rocks that were changed by heat and pressure within the Earth.
Matter
Matter is anything that has mass and takes up space. It exists in three states: solid, liquid, and gas. In solids, particles are tightly packed; in liquids they are less tightly packed; and in gases particles move freely. Matter can change states through heating and cooling - for example, water exists as a solid (ice) when cold, a liquid at room temperature, and a gas (water vapor) when boiled. Changes between these states are called melting, freezing, boiling, evaporation, and condensation.
Matter
Matter is anything that takes up space and has mass. Everything you can see, smell or touch is made of matter, including invisible things like air. Matter can have properties like size, shape, color, texture and hardness that can be observed through the senses. Properties depend on what materials something is made of.
Living things get energy
This document discusses energy flow and food chains in ecosystems. It explains that producers like plants get energy from sunlight to make food, while consumers eat other organisms or producers for energy. Decomposers break down dead organisms and waste, releasing energy back into the ecosystem. Food chains show how energy passes from producers to consumers. Multiple overlapping food chains combine to form complex food webs, where a change in one part can impact other parts of the ecosystem. The document gives an example of how reducing the habitat for prairie dogs due to human settlement can negatively affect other species in the food web like black-footed ferrets and badgers by decreasing their food sources.
Life cycles of some plants
Plant life cycles involve distinct stages of growth, reproduction, and renewal. Flowering plants grow from seeds into seedlings with roots and stems, then mature plants with leaves that photosynthesize and flowers that are pollinated to produce seeds. Conifer plants similarly grow from germinated seeds into seedlings and then adult trees that bear pollen cones and seed cones, with wind dispersing pollen to fertilize the seed cones and produce new seeds. Other plant life cycles include strawberries that form new plants from stems that take root, dandelions that spread via roots, and kalanchoes and ferns that reproduce via spores.
Life cycles of some animals
The document describes the life cycles of several animals including eagles, butterflies, frogs, and mammals. Eagles lay eggs which hatch into eaglets. Butterflies go through stages of an egg, larva/caterpillar, pupa, and finally an adult butterfly. Frogs undergo metamorphosis from eggs to tadpoles to adult frogs. Young mammals like bobcats develop from eggs inside their mother's body and are born as kittens, growing into adults.
How is matter measured
This document discusses different ways to measure and compare matter, including length, volume, mass, and temperature. Length is measured using a ruler or meterstick in units like meters, centimeters, and millimeters. Volume is measured using a graduated cylinder in units like liters and milliliters. Mass is measured using a balance in units like grams and kilograms. Temperature can be measured on the Celsius or Fahrenheit scales using degrees.
Features of earth`s surface
The document describes different types of landforms and features found on Earth's surface, as well as processes that shape them. It explains that landforms include mountains, hills, valleys, and plateaus. Bodies of water and glaciers also shape landforms by eroding and depositing material. Volcanoes and earthquakes cause rapid changes through erupting lava and shifting crustal plates, which further alter the landscape over time.

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.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

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.
