How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, learners model ancient lunar impacts using water balloons.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this math lesson, learners participate in several activities where they apply measurement skills.
