Third Grade Science

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Identify and interpret the earth's different water sources. Third and fourth graders describe and demonstrate the process of the water cycle, make a model of its two main parts, and predict and infer to answer questions about the model. 

What are the basics for building a rocket out of a two-liter bottle? The procedures outline the basics to create an air- and water-powered bottle rocket. Prior to launching the rockets, teams perform safety checks to ensure their designs...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Send youngsters home to survey how they use water in their homes. Then bring them together to discuss which uses are essential for our health and which are not. A helpful video offers teaching tips for this lesson, and a presentation...

Young scientists create their very own aquifers in this science lesson on ground water. After learning about how some people get their drinking water from underground wells, young learners use sand, modeling clay, and aquarium rocks to...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration, and precipitation as a...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.
