In this kinetics worksheet, students solve twenty one problems related to reaction rates, half life, reaction orders, catalysts, and activation energy.

In this conservation of energy worksheet, students read about the law of conservation of energy and about energy distribution. They answer three critical thinking questions about what the law of conservation of energy means to us for...

Students explore history of technological advances in making, recording, and listening to music that have intrigued and inspired musicians and scientists for decades.

Young scholars explore biology by participating in a dietary habit activity. In this food chain lesson, students discuss their own diets and the animals we feed upon daily. Young scholars create a poster demonstrating the animals that we...

Students engage in research that investigates the economic concept of supply and demand. They look at the problem and how it can shift periodically in an economy. Students graph different quantities and see the shift in a visual way and...

Students discuss both positive and negative economic incentives. In this lecture-based lesson, they examine a simulation about profiteering drug companies and what might happen if the FDA controlled drug production.

Third graders research ecosystems, the work of ecologists, John Muir's contribution to the environment and an endangered species of their choice. They read books, participate in discussions, and write reports.

Students comprehend that when they use a credit card, they are taking out a loan from the issuer of the card. They access that if a card is paid in full each month, there is no cost for using the credit card. However, if the borrower is...
