How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local streams....

Ninth graders utilize several different types of maps to forecast weather conditions specific areas of the country. Air masses, wind, cloud types, fronts, and the pH of the rain is explored in this lesson.

Sal builds on the previous video which shows students how to calculate the mass composition of a compound from its empirical formula. This problem uses the elements Hydrogen, Oxygen, and Sulfur. The process requires quite a bit of...

Warning: there are no lifeguards in the gene pool! An educational video compares and contrasts DNA and RNA. It includes the three types of RNA as well as the four bases of RNA.

Energy is conserved? Prove it! The narrator does just that in a short video depicting the mathematical proof of conservation of energy. Young physicists see how the kinetic and potential energy present in a system are related to one...

Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.

An online resource, this worksheet has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and...

Jellyfish range in size, species, hunting habits, and venom secretions. But one thing most all jellyfish have in common is their ability to survive and flourish in our oceans since before dinosaurs. Watch the video and find out just how...

High schoolers estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. High schoolers...
