What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

What do budding scientists know about moles and reactions? Using an attention-grabbing lab experiment, young scholars collect data to apply the law of conservation of mass to predict the mass of gaseous products. They examine several...

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...

A demonstration of elephant toothpaste hooks pupils' interest as they complete multiple experiments with colors, smells, bubbles, and more. By the end, they understand the differences between physical and chemical changes in the world...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

No one likes kidney stones, but they are very interesting to learn about. The last installment of a three-part unit has learners experiment with different chemicals to see which one inhibits the growth of calcium oxalate crystals (which...

Make an impact on young physicists with this fun collection of resources. After first watching a video and taking notes on the physics of car crashes, students go on to complete a series of activities that explore the...
