In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

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

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

Learners use a simple process to extract DNA from strawberries.

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.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

Learners design their own experiment to investigate how pollution diffuses through ground material.

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

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

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

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

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

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity, learners make self-assembled polymer spheres.

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).
