Students learn how scientists turn everyday curiosity into questions that can be tested through observation, measurement, and evidence. They’ll distinguish testable questions from questions based on personal opinion.

Students investigate which paper towel absorbs the most water while learning how variables and constants create a fair scientific test. They’ll see why scientists change one variable at a time to make meaningful comparisons.

Students test how changing the shape of paper affects its strength by comparing flat and accordion-folded structures. They’ll explore how engineers use shapes and structures to support loads and create stronger designs.

Using a toy car, students investigate how pushes and pulls can start motion, change speed, and change direction. They’ll connect forces to familiar movements they experience every day.

Students test a toy car across different surfaces to discover how friction affects motion. By measuring repeated trials, they’ll see why cars generally travel farther on smoother surfaces and how friction can also be useful.

Students use a simple rope activity to investigate what happens when opposing forces are equal—and what changes when one force becomes stronger.

Students experiment with different ramp heights, collect repeated measurements, and investigate how gravity and stored energy affect a toy car's motion.
