Is there anything that can be done to slow the browning of fruit once it has been cut? High schoolers determine the answer through five different investigations involving apples, potatoes, and chemical reactions. After each experiment,...

A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...

Students observe the changes between elodea leaves placed in darkness and light.  In this life science lesson, students experiment to find evidence of photosynthesis in elodea leaves. Students use indicators to detect the presences...

Pupils discover the different alternative fuel sources. In this biology lesson, students identify the different stages of the carbon cycle. They explain the pros and cons of using alternative energy.

Learners identify the different biotic and abiotic components of an ecosystem. In this ecology lesson, students perform a case study on current environmental problems. They write a position statement about their chosen topic and share it...

Students study the environment and interactions of living organisms. They identify abiotic and biotic factors and create a foldable and vocabulary cards. They create a poster illustrating soil and watch a video to study symbiosis.

Seventh graders simulate the capture-recapture method of population sampling using beans. In this biology lesson, 7th graders calculate the total population of beans in the bowl. They assess whether this method is reliable or not.

Young scholars examine the characteristics of fungi. In this biology lesson, students investigate the factors needed for fungi growth. They collect data and observations and write a report about them.

Tenth graders examine the different parts of the heart. In this biology instructional activity, 10th graders perform dissection of the fetal pig. They explain how the heart maintains homeostasis.

Students explore biotechnology through various activities. In this biology lesson, students analyze its pros and cons. They study and read informative articles about biotechnology.

High schoolers explain the basic concepts of polymerization. Students participate in a lab to create a crude preparation of carboxyl esterase and test its effectiveness in reducing the residual monomer in an emulsion such as paint.

Students explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

Learners describe the characteristics of algae. In this biology instructional activity, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.

Students collect data on the differences in Hominid skulls using acrylic casts of fossil skulls. They measure a series of structures on skulls from six different species then use the data to determine evolutionary relationships between...

Young scholars explain the importance of having a control when setting up an experiment.

Food preparation that supports the concepts of adding fiber and water to the diet. Identify fiber, its sources and functions. National Standard 14.2.1 Identify the function of fiber Identify cellulose - non digestible fiber Discuss the...

Students sample a site with low human impact, one with moderate human impact, and a third with high human impact. Students chart the data for each site and then compare the sites and discuss.

Young scholars describe the science of physics. In this Physics activity, students observe examples of physics within their classroom. Young scholars create a definition for physics.

Young scholars examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino...

Suitable for an AP Biology class, the lab found here has teen bioengineers working with plasmids to clone DNA. If you have not done a similar lab, the instructions may be rather difficult to follow. Both the teacher and learner...

Students examine insect behavior in a lab activity. Students explore the idea of chemical specificity and the reactions of termites to a chemical found in their trail pheromone. Students watch a demonstration with termites before...

Learners are given this authentic assessment format after the study of any laboratory activity (or group of labs). It's purpose is to replace the lab practicum when it is not possible to do a real set-up and /or to serve as a make-up...

Students investigate the interference of various drugs on an embryo through experimentation. This is an open-ended lab to allow students to see effects of various chemicals humans choose to put in their bodies and create questions they...

Students explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation. This lesson is...
