Students correlate signs of spring with reproductive strategies of varioius organisms. They describe how organisms inherit traits from generation to generation.

Students observe tadpoles as they gradually change into adults.  In this amphibian biology instructional activity, students watch tadpoles in a tank in the classroom, keep a daily record of what they observe, and chart the growth...

Students identify different plant hormones and explain their function in plant development. In this biology lesson, students investigate how IAA affect root growth. They study the history of auxin discovery.

Second graders examine the characteristics of animals who live in a pond environment. In groups, they describe the various stages in the life of a frog and identify the characteristics of other pond animals. Using this information,...

Students explore friction as a force that slows moving objects, explain conclusions in terms of the roughness or smoothness of surfaces, relate results to predictions, and begin to know how to plan a fair test.

Young scholars examine ways for people to stay healthy, such as exercising and eating right.

Students participate in a demonstration and complete an online activity that illustrates the earth orbits the sun once a year, and that the moon takes approximately 28 days to orbit the earth.

Students compare the properties of rocks and relate these properties to their use. They perform a virtual experiment to describe and group rocks on the basis of their characteristics.

Young scholars identify the main parts of the human body. They point to various parts of their own body, cut out pictures of humans and animals and sort them into the two categories, discuss the differences between animals and humans,...

Fourth graders study food chains, producers, consumers, and decomposers. They play a food chain game and create food chain mobiles or posters. They take a nature hike around the school and observe various parts of a food chain.
