Specific Gravity of Wood

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Young scholars apply abstract concepts, such as stress, fulcrums, the law of gravity, and the strength of different geometric shapes. Groups of student contractors operate simulated architectural firms to create strong, economical bridges.
