Do domed structures have advantages over their less-than-spherical counterparts? Junior architects explore the pros and cons of domes through a design challenge. Teams work together to plan, sketch, build, and test domes created from an...

It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.

Let there be light—or maybe not. Pupils learn about light pollution with an investigation of constellations. They create constellation boxes and experiment with different levels of light. Observations are then made about the lighting in...

Students examine how a hot air balloon works. In this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

Students design a craft that safely floats vegetables across a classroom. The teacher provides some materials, but the child may as well. As the experiment is created, they have to fill out worksheets to keep the actiivity organized....
