Preparation and Combustion of Biodiesel
The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the results...

Energy Content of Foods
Why do athletes load up on carbohydrates the evening before a competition? The lesson plan helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars perform an experiment...

What's So Special about Bottled Drinking Water?
Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Harmonic Motion: Pendulum Lab
Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Projectiles: Target Practice
Angry Birds prepared them, but now pupils must prove their skills with projectiles! Scholars test different variables to determine which ones impact the distance the projectile flies. The experiment provides connections to kinetic and...

Law of Conservation of Matter
Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Is Yeast Alive?
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...

Mineral Mystery Experiment
One way to study something is to try to replicate it. Young scientists do just that as they use solutions to recreate mineral structures on a dwarf planet. They make solutions with different types of salt, evaporate them, and observe the...

Whip Up a Moon-Like Crater
The moon is famous for its craters, but they haven't always been there. Young learners experiment with materials to simulate the creation of moon craters. Pupils are able to see patterns in their materials that are similar to the...

A Splash of Color - Is Pure Water Colorless?
What makes the ocean blue but a glass of ocean water nearly colorless? Investigators prepare tubes of water to examine the color of water. Scholars discover the relationship between light absorption, color variations, and water depth as...

Heat Up and Cool Down
Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...

The Fate of Calcium Carbonate
Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Chromatography - Color Clues
Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Chemistry Color Changers
Knowledge of acids and bases doesn't need to be a secret. Learners use red cabbage to create an indicator solution, then test how adding lemon juice (acid) and detergent (base) changes the color of the solution. They then use the concept...

Chemistry and Comics
Copying the comics couldn't be easier. A fun and simple activity has young scientists rub the back of a comic strip with a spoon to see if the ink will transfer to a white sheet of paper. They then repeat the experiment, rubbing...

Aware of the Air
It's there, even though no one can see it. Scholars create two different-sized parachutes out of shopping bags, then let them fall through the air. They should see that the larger parachute falls more slowly and interpret this to mean...

All Wet
Sometimes liquids just don't get along together. A fun experiment has scholars determine whether various liquids dissolve in water. They pour isopropyl alcohol, vegetable oil, and corn syrup into cups of water to see which ones mix well...
