In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
