In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners take their own pulse and explore how heart rate is affected by various activities.

In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

Learners make their own simple slide rules out of paper and learn how they work.

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
