In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.
