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 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.

WeatherWhat is the weather like outside? Weather is the condition of the air outside. Weather involves many things, such as clouds, temperature, water in the air, and the wind. Read more...iWorksheets :3Study Guides :1Vocabulary :2 WeatherWhen someone asks, “What is the weather today?” you know what they are asking. They are asking what it is like outside. They want to know what nature is doing in your area – raining, snowing, blowing… How We Measure Weather: We measure temperature using a thermometer. A wind vane measures the direction of the wind. A rain gauge measures how much rain falls.Read more...iWorksheets :4Study Guides :1Vocabulary :2 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.

Students use science and engineering practices, crosscutting concepts, and an understanding of the Earth and human activity to make sense of phenomena and solve problems.
SCI.ESS3.A. Natural Resources
SCI.ESS3.A.K. Living things need water, air, and resources from the land, and they live in places that have the things they need. Humans use natural resources for everything they do.
Using and saving natural resourcesNatural resources are found on the Earth and are important to living 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 SCI.ESS3.B. Natural Hazards
SCI.ESS3.B.K. In a region, some kinds of severe weather are more likely than others. Forecasts allow communities to prepare for severe weather.

There is a layer of gas that surrounds Earth, which is called the atmosphere. 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!
