Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

After collecting carbon dioxide bubbles from a cup of club soda, learners attempt to make their own lemon soda while preventing the loss of carbonation. They do so by creating a syrup before mixing the substances into the club soda....

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Why is it so difficult to make two solid compounds react? Investigate the concepts of particle collisions and rate of reaction using a quick demonstration. The colorful experiment features two plain, white solids combining to form a...

Make the connection between Hooke's law and elasticity with an activity that introduces the class to the behavior of elastic materials. The resource defines stress and strain to calculate the modules of elasticity of...

High schoolers investigate the effects of temperature and concentration on the rate of reactions. In this "clock reaction" kinetics lesson plan, students change the concentration of one reactant and keep the second constant. An indicator...

In this batteries worksheet, students read about how batteries work and the types of batteries. They answer three critical thinking questions about batteries and their use as alternate-fuel sources.

Students study the concept of ice energy. In this ice energy lesson, students observe what happens when salt is sprinkled on a piece of ice before following a recipe to make two types of ice cream. They note the difference in the two...

Students identify the composition of different pennies. In this chemistry activity, students use a post 1982 penny to observe chemical change. They explain how to turn a penny from copper to gold.

Students conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a chemical...

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

The Henderson-Hasselbalch equation combined logarithmic terms with the application of carbonic acid as a buffer solution. Scholars learn investigate equation and its applications through hands-on experiments. They collect data and...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...

We have all heard that we are what you eat, but what are we eating? An informative lesson opens with a discussion of the foods pupils have recently eaten. Then, young scientists perform four experiments on seven...

Create a coat of armor for dinosaur volunteers. Young scientists explore the oxidation-reduction reaction facilitated by electric current. The result of the reaction is a dinosaur coated in copper and zinc, which leads to an...

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.

Eighth graders observe evidence of chemical reactions.  In this chemical reactions instructional activity students study chemical processes and complete a lab activity. 

High schoolers determine the activation energy of a chemical reaction.
