How do greenhouse gases affect the climate on Earth?  Pupils explore the concept by first building their own apparatuses to model the greenhouse effect. Then, they record data to measure temperature change and determine...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these...

Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...

Why does Earth experience summer, fall, winter, and spring? Using an informative demonstration, learners see how the angle of the sun on Earth and the rotation of Earth determine the seasons. Scholars work in pairs to learn that the...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction,...

Elementary school physical scientists explore kinetic mechanical energy by dropping a golf ball on different surfaces. They discuss how human made materials might react to light differently from nature made materials. This lesson plan...

How many jackets do you need to stay warm and climb Mount Everest? An informatie resource covers the topic of Mount Everest, the resource helps young scientists discover the difference between climate and weather. Activities include...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. For this geologly lesson, learners use scientific equipment to collect...

Using the scientific method, and bubble gum, learners conduct a motivating experiment. After conducting a series of tests involving bubble gum, they graph and analyze their results. This is the type of activity everyone loves.

Third graders practice making predictions about weather from conditions they observe on weather instruments and weather reports. Learners are introduced to the most basic weather reporting instruments: the thermometer, the wind vane, the...
