In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this environmental health activity, learners investigate their own vital lung capacities.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
