Students observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...

Learners discover how the sense of sight helps us recognize each other and explore color, motion and distance.

Students explain how cells reproduce. In this biology lesson, students explain the different stages of the cell cycle. They calculate the number of new cells produced.

Students obtain remote sensing data to compare and contrast global biomass data with global temperature data.

Young geologists utilize Moh's hardness scale to help them correctly sort and classify different types of rocks. This activity has everything you need, including an excellent example of the Mohs' Hardness Test, to successfully implement...

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

Sixth graders study living cells and their functioning units.  In this cell lesson students color cell diagrams, answer questions and discuss the differences between plant and animal cells. 

Tenth graders study plant and animal cells.  In this investigative lesson students draw their own animal cells and label them. 

In this recognizing facts about seahorses worksheet, students read descriptive phrases and match them with the terms they are describing. Students match 9 answers.

Learners identify and experiment with dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their...

Middle schoolers participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Observation of sister chromatids is possible as students culture and stain mammal tissue cells.  

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Students compare kelp and land plants. In this sea plant lesson, students look at the role of algae in aquatic environments. They research the properties of kelp and explore seaweed. 

Students collect microorganisms, demonstrate correct laboratory/Gram stain procedure, and design and construct tables to organize data.

Students build plankton models and compete to see which sinks most slowly. They write, or orally present ,the adaptations they incorporated to slow the sinking rate of their organisms. Race results can be grounds for some prizes!

Students read background information about Monterey Bay, California, and conduct related experiments. In this ocean in motion lesson, students read information about the location, wildlife, and characteristics of Monterey Bay. They...

Students identify the parts of plant and animal cells, how samples can be obtained and what the differences are.

Seventh graders investigate the strength of the muscular system. They explore voluntary and involuntary muscle movement and discuss the types of muscles: cardiac or heart, skeletal, and smooth. They visit stations to answer questions...

Students investigate with sea urchins. In this ocean habitat lesson, students observe sea urchins and other ocean grazers. Students work with lab equipment to examine the anatomy of these creatures.

Fifth graders compare technology and the human eye. For this science lesson, 5th graders label the parts of the human eye and trace the path of light as it travels through the eye.

Students discover algae. In this science lesson plan, students examine what green algae is and where it grows. Students test the growth of algae in four different types of water: lake water, well water, distilled water and tap water

Pupils analyze data to make hypotheses and conclusions regarding the predator/prey relationship between moon snail and surf clams.
