Time Trials
Students investigate speed, time and distance. For this algebra lesson, students utilize their knowledge of linear equations to solve problems related to time, speed and distance. This assignment is hands on using two toy race cars.
Curated OER
Extinction
Students explore reasons why the dinosaurs became extinct, and the specific needs (habitat, environment, food) of individual types of dinosaurs.
Curated OER
Cool Suits
Students examine the materials that are used to make space suits. They complete an experiment in which they test different materials in different colors to determine the best one for keeping astronauts comfortable. They analyze the data.
