Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a...

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Students, operating under simulated budget constraints, build pop-rockets and launch them. Working in pairs, they complete budget worksheets and use their "Blast Off Bucks" to pay for the construction. They then redesign their rockets...

Students describe how temperature and surface area exposure affect the rate at which fuel is consumed. They explain why engineers want to know about the properties of a fuel when designing rockets. They create a bar graph of result data.
