Middle schoolers build an apparatus to look at how yeast cells grow by converting food to energy. They observe yeast both with and without food and see how yeast produces carbon dioxide.

Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...

Students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid tablet and water -...

High schoolers observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to...

Students investigate how plants absorb carbon dioxide during photosynthesis. In this biology lesson, students differentiate photosynthesis and cellular respiration. They discuss the important role of plants in the environment.

Students pick a tree they see everyday. They measure the tree's circumference and estimate its height using similar triangles. Students are introduced to Computational Science. They use computers and calculators to compute values...

Young scholars explain how zoo-plankton have an impact on the global process.  In this ocean zoo-plankton lesson plan students calculate carbon flux and plankton densities. 

Sixth graders discover scientific processes by conducting an experiment in class. In this osmosis lesson, 6th graders utilize eggs, cooking ingredients, string and plastic cups to create an experiment in which they watch the exchange of...

Young scholars conduct experiments using bananas sealed in jars to observe the effects on biodegradable waste in landfills. They cover the lid with a plastic sandwich bag to create an airtight seal. Students observe how the oxygen is...

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

Students conduct experiments showing the greenhouse effect. In this scientific experiment lesson, students test for CO2 concentration, water vapor, ground albedo, and clouds. They describe what factors affect temperature and how...

Students experiment with yeast. In this environmental conditions lesson students test the viability of samples of yeast. Students investigate the effects of environmental conditions on the yeast.

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Students observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

What do a dead fish, conservation, and paint have in common? The answer is a great instructional activity about fish anatomy, fun print making techniques, and unsustainable fishing practices. The class will start by making fish...

In this photosynthesis worksheet, learners use a textbook to research the different scientists involved in the discovery of the process of photosynthesis. This worksheet has 31 fill in the blank questions.

The higher the number of letters in the final word for the National Spelling Bee, the higher the number of people killed by venomous spiders. Obviously, those two facts correlate, but no causation exists. Scholars view data based on...

Students examine various techniques that can reduce carbon dioxide in the atmosphere, and use chemistry to simulate oceanic sequestration. They conduct an experiment involving the method of oceanic absorption for carbon sequestration,...

Students conduct experiments with plants.  For this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...
