Students investigate cells. They discover what cells are, where they are found, what they do and what they are made of. They construct a giant cell that is posted on the bulletin board.

Students examine the needs of trees and plants. In this forest ecosystem lesson students use seedlings to investigate the basic necessities of plants. They discuss the consequences of these basic needs not being met.

High schoolers conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.

Students collect samples of common dust from their homes and school for examination under a microscope. They identify the components of their samples using the provided "Atlas of Indoor Dust Particles." Pupils take samples form a variety...

Students create a mural showing ocean zones and the diversity of ocean life. They use reference books to create a list of plants and animals that would live in each zone.

Students explore human senses. In this applied Science lesson, students utilize their senses to distinguish various objects. Students explain their descriptions.

Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.

In this mini pond worksheet, students create a mini-pond ecosystem with soil, water, and plant life. Students let their ecosystem sit for a day and they observe a sample the next day. Students identify all the pond water microorganisms...

Students examine protozoans and their advantages and disadvantages.  In this chemistry lesson students explain what a protozoan is then draw and label one. 

In this human cells activity, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

Students become familiar with common microorganisms and experience exploring the microbial world.

In this bioluminescence worksheet, students read about various organisms that glow on land and in the sea. They answer three critical thinking questions after reading about these chemical reactions.

Second graders examine compost piles and what invertebrates help decompose the organic matter.  In this compost invertebrates lesson students collect invertebrates found in a compost pile and examine them.
