In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
