Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

In this math lesson, learners explore polynomial and rational function patterns.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

In this math lesson, learners compare products to determine the best product.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this math activity, learners play a game similar to 20 Questions, in which learners must identify a secret number drawn from a bag.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
