Diffusion & Osmosis with Data Analysis
Source Institutions
This three-part lab helps learners understand the essential principles governing diffusion and osmosis.
Many Seeds: Estimating Hidden Seeds
Source Institutions
In this activity, learners will estimate how many seeds are in a fruit or vegetable, then count to find out. The result: mix estimation with healthy eating.

Disappearing Crystals
Source Institutions
Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

Shower Estimation
Source Institutions
In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.
Balance Challenge
Source Institutions
In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!
Pour Some: Measure Serving Size
Source Institutions
Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.
Narrow It Down: Asking Yes-No Questions
Source Institutions
In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.
