Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Sink or Float?
Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.

Curated OER
Sink or Float?
Young scholars will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e.,...

Water and Ice
Learners investigate the states of matter. In this physics activity, students use water and ice to demonstrate the characteristics of a solid and liquid. Learners record their observations as the state of the water changes.
Curated OER
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...
