Students use a globe and cups of water to illustrated the amount of water versus land on earth and the amount of fresh versus salt water available to plants and animals.

Students determine the sequential links in a marine food chain and identify the roles that various organisms play in this chain. Students develop charts as visual aids for illustrating marine food chains.

First graders experience the growing process of a seed becoming a flower as it is exposed to the sun, rain, wind, day and night, and -tickling- bees as they move creatively to music.

Pupils investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-activity series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Students examine how machines help people grow food. They study specialized types of farm machines and the tasks they perform. They complete handouts matching images of the machines with text.

Students observe skulls of wild animals and determine their characteristics for survival. They evaluate the skuylls to discover the diets, and if the animals were predators or prey. They complete worksheets on mystery skulls.
