Earth's weather and seasonsWhat is Weather? Weather is what it feels like outside right now: hot, cold, windy, wet... There are Four Seasons: Winter, Spring, Summer, Fall. Seasons always come in the same order every year. Each season brings different weather. Winter is the coldest season and summer is the warmest. Some Kinds of Bad Weather: A thunderstorm, A blizzard, A hurricane.

Some lived on Earth millions of year ago. Many of these animals unfortunately do not live on Earth anymore. Fossils are things that provide evidence (or proof) of things that lived long ago. A fossil is the outline or piece of something that died millions of years ago. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 The sun and earthThe Sun is a large hot ball of gas. It is also a star. The Sun gives Earth light and heat. Living things need the Sun to live! Sun rays shine on the moon at night which makes the moon bright! The Earth is the third planet from the Sun. There are four seasons: winter, spring, summer, and fall. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 All about sound and lightHow is Sound Made? Sound is made because of something vibrating. You hear sounds when vibrating air causes your eardrum to vibrate. How Are Sounds Different? How Does Sound Travel? How Do People and Animals Make Sounds? What is Light? Light is also a form of energy. Light is energy that travels at very high speeds. Where Does Light Come From?

If something is magnetic, that means it is attracted by a magnet. Magnets come in different shapes and sizes. Magnets are used most every day. Example: You may have magnets on your refrigerator to hang up pictures and notes. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 PlantsWhat are the Parts of a Plant? Let’s go from the bottom to the top: ROOTS, STEM, LEAVES, FLOWERS. Who Needs Plants? EVERYONE! Plants give off a gas called oxygen which is what we (and animals) need to breathe in to live. A plant's life cycle is how long a plant lives or how long it takes to grow, flower, and make seeds. All plants need water, air, and warm temperatures to grow.

Scientists who study the weather are called meteorologists. Some plants like ferns do not have flowers. They make new plants using spores instead of seeds. The cheetah is the fastest animal in the world. Cheetahs can run up to about 113 kilometers per hour. The arctic is the coldest habitat. Brrrr!

ESS2. Earth’s Systems
2-ESS2-3. Use examples obtained from informational sources to explain that water is found in the ocean, rivers and streams, lakes and ponds, and may be solid or liquid.
Changes on earthA glacier is a slow moving large body of ice. A volcano is an opening in the Earth’s crust from which hot, melted rock forcefully comes out when pressure is built up inside the Earth. An earthquake is a sudden shift in the Earth’s crust that causes the ground to shake and vibrate violently. Weathering is the process of rocks being changed over time by conditions such as rain, snow, ice, pressure.Read more...iWorksheets :4Study Guides :1Vocabulary :3 Moon, star and planetsThe moon moves around the Earth. A star is a hot ball of gas, stars give off light. The Sun is a star. Read more...iWorksheets :3Study Guides :1Vocabulary :2 Rocks, Soil and waterWhat are Rocks? Rocks are solid objects found in nature. Rocks are made up of minerals. What is Soil? Soil is the loose material the covers much of the Earth. Soil is also nonliving. Soil can be made of clay, sand, and humus. All living things need WATER to survive and to grow. The movement and recycling of the Earth’s water is called the water cycle.

Birds are warm-blooded animals that have: wings, feathers, a beak, no teeth, bones. Birds lay eggs. Their young hatch from those eggs. What Are Mammals? Mammals are animals that have hair. Mammals are the only animals with hair. Mammals are also warm-blooded. This means their body temperature stays the same, even if it is very cold or hot outside. Read more...iWorksheets :4Study Guides :1Vocabulary :1 Reptiles, amphibians and fishReptiles have scales. Reptiles are born on land. Reptiles are cold-blooded which means their bodies change temperatures with the outside temperature around them. Reptiles lay eggs, and their babies hatch from those eggs. All amphibians begin their life in water with gills. As they grow, they develop lungs – which is
what they use to breathe with on land. They grow legs to use on land too. Fish use gills to breathe. A fish stays in the water for its entire life! Read more...iWorksheets :4Study Guides :1Vocabulary :1 Earth yesterday and todayLife on Earth Has Changed. Many kinds of animals that used to live on Earth are no longer living. They are extinct. Reasons for Extinction: Big changes in the climate. Many times animals could not handle these big changes in the weather. Good news: Many animals have adapted to many changes that happen on Earth so that they CAN survive and NOT become extinct! Read more...iWorksheets :3Study Guides :1Vocabulary :1 LS4. Biological Evolution: Unity and Diversity
2-LS4-1. Use texts, media, or local environments to observe and compare (a) different kinds of living things in an area, and (b) differences in the kinds of living things living in different types of areas.
Where plants and animals liveAn environment is everything that surrounds a living thing or person. Everything that lives on Earth lives in a certain environment. Living things get everything they need to survive from their environment. An environment also includes nonliving things.

People, plants, and animals need air to live. Air is a natural resource that never runs out! Water is another natural resource that people and animals use – they drink water in order to survive. Plants also need water to grow. Some natural resources are renewable. Read more...iWorksheets :3Study Guides :1Vocabulary :2 Science in our worldWhat is Technology? Technology is using science in order to solve different problems. Technology uses things we know about science to make tools for people to make doing work easier.

Scientists often make predictions based on all the things they already know are true. Predict means to tell what you think is going to
happen. Scientists then test their predictions to see if they are right! Scientists often compare and sort objects based on color, shape, texture, size and weight. Scientists use a METER STICK to measure the length of an object. Read more...iWorksheets :3Study Guides :1Vocabulary :1 2-PS1-3. Analyze a variety of evidence to conclude that when a chunk of material is cut or broken into pieces, each piece is still the same material and, however small each piece is, has weight. Show that the material properties of a small set of pieces do not change when the pieces are used to build larger objects.
Changes in matterA physical change is when something changes its appearance without changing its makeup. An example of a physical change is chopping wood. An example of a chemical change is burning the wood. Read more...iWorksheets :3Study Guides :1Vocabulary :1 What is science?Science is the study of the world around us.
