In this activity, learners explore dinosaur skeletons.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

Build a house you can fit inside, using cardboard tubes.

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 math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

When a lot of people share one network (such as cars using roads, or messages getting through the Internet), there is the possibility that competing processes will create a “deadlock," or an interrupt

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In ancient Chaco Canyon, the people used a "sun dagger" petroglyph to mark the passing of seasons.

In this math lesson, learners apply measurement skills to determine, in dollar bills, the capacity of a suitcase.

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

In this activity (8th activity on the page) about the sense of touch, learners make their own set of Braille letters. Learners use glue to make raised dots on a Braille Alphabet Sheet.

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