Students conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.

Students study living and non-living materials that are found in soil. They study the things required by plants and animals to remain healthy. They design a collage of sand, stones, leaves and other natural items.

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Students trap, collect and identify arthropods in a newly created desert tortoise preserve area over a period of one school year. They determine the rate at which various arthropods take up residence in the newly landscaped area. Data is...

Explorers set up Windogradsky columns with local mud so that they can culture microorganisms. After three and six weeks they make observations of the mud and the organisms growing in it. In this way they observe succession and relate...

A continuous cascade of information comes through this PowerPoint on biotechnology. The topic is defined, a history is presented, and basic genetic engineering techniques are explained. The topic is covered in an objective manner,...

Students are introduced to the challenges involved in understanding the space travel distances and the time involved to do so through the use of an interactive fable. The modeling and comparisons deal with specific distances at different...

Students observe the life cycle of the common flour beetle and make observations of its life stages. They also design and implement an investigation on food preference for the beetle and record data over a period of several months....

Multiple choice, fill-in-the-blank, short answer, and matching questions are all here in a multi-page worksheet or quiz. While the formatting leaves a little to be desired, it would take just a few minutes to change the handout into a...

Fourth graders observe brine shrimp over several days. They create drawings showing the growth and development of the shrimp. They research web sites to find out where brine shrimp fit on the food chain and what makes the shrimp unique.

Students investigate atoms as particles that make up all matter. They examine the mass of matter.

Students analyze cancer data represented in graphs and charts. They describe the changes in cell structure and function as the result of cancer. They also examine phenomenas that are believed to cause cancer.

Students discover many facts about horseshoe crabs. Students identify the main body parts of horseshoe crab. They explore the habits of the horseshoe crab and their importances to the ecosystem. Adaptations for younger students are...

High schoolers observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

Students begin the lesson by collecting sand at low tide from a local beach. They place each specimen on trays with a tiny amount of seawater. After a week, they can observe the meiofauna present in the sand through a microscope. They...

Students view "The Danger Zone" to learn about food poisoning and the bacterial causes and prevention. Students look at slides, use a worksheet, "Microbial Bugs"and the internet to identify and learn about each bacterium.

Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.

Learners use a written key or illustrated key to identify fungi on plant leaves into its genus based on sexual or asexual reproduction, host range diversity, and host-parasite relationships.

Students examine an ecosystem and record what they see.  In this ecosystem lesson students use a worksheet to help them identify the organisms in their ecosystem. 

Students observe mold growth on bread. In this mold growth lesson, students place bread in various locations and in various conditions to investigate how location, moisture, temperature, and other variable impact the growth of mold on...

Students investigate the effects of urban pollution on plankton. In this plankton and pollution lesson plan, students use samples of plankton collected in urban areas to observe the effects of pollution on plankton samples. They...

Eighth graders, after creating a Venn Diagram comparing/contrasting animal and plant cells, writing ten similes describing cell types, or drawing a colored diagram of a cell, list cell types as well as describe and label cell parts. They...

Learners discuss certain properties of salt and how it is used every day as well as harmful uses. They experiment with salt to see it conduct electricity, form crystals and water freezing temperature. They complete a worksheet to record...
