Fossil fuels are non-renewable resources and have become crucial to the livelihood of countless individuals. Young chemists investigate an alternative method of generating energy by performing a series of activities that lead to the...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

After watching an engaging 13-minute video about the colorless blood of icefish, future ichthyologists examine icefish blood and non-icefish blood (blood samples are simulated with Karo syrup mixtures) to determine advantages of...

Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your...

Ah, caffeine! What would some of us do without it? Teach your high school chemistry class the concept of sublimation as they complete a hands-on experiment to visualize the changes caffeine undergoes during heating and cooling. They...

Enhance your class' ability to understand solubility. Science scholars examine how temperature and concentration affect solubility using an interesting lab experiment. The introduction and procedure also discuss the relationship between...

The Manhattan Project was a massive undertaking involving multiple sites and thousands of scientists and technicians. To gain an understanding of the women who participated in the project, groups select an oral history of a woman...

A lesson about the Manhattan Project will explode young physicists' understanding of the racial attitudes in the United States during and after World war II. Groups select an African American scientist or technician that worked on the...

Use whatever material floats your boat. Working in groups, scholars decide on a type of metal and a type of coating to use for building a boat. They test their creations by leaving their boats in a pool of water for several days before...

Technology can help save money and add convenience. The resource offers a free textbook for a complete Chemistry course. The text begins with a review of the scientific method and continues to explain topics such as chemical bonding,...

The components of the atmosphere have a significant impact on long-term climate change. Learners begin by analyzing the role of carbon dioxide in the earth systems and how varying the levels would affect those systems—and ultimately...

Two different groups of scientists published scientific papers in 1980 offering proof of a large asteroid hitting Earth between the Cretaceous and Tertiary layers of ground. Scholars use a worksheet to analyze the same type of data as...

Should we be afraid of a large asteroid impact on Earth today? Young scientists estimate the size and composition of an asteroid similar to the one that caused the K-T mass extinction. They apply algebraic formulas to answer questions...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...
