In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.

Ramps 1: Let it Roll!
Source Institutions
In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

Digit's Cyber-Dough
Source Institutions
In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

Don't Crack Humpty
Source Institutions
Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

Ball Bounce Experiment
Source Institutions
In this activity, learners investigate the properties of different types of balls.

The Length of My Foot
Source Institutions
In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.

Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

Sled Kite

In this activity, learners build a sled kite that models a type of airfoil called a parawing.
What's the Difference?
Source Institutions
In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

Catapult
Source Institutions
In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

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

How to Learn Basic Shapes by Making a Shape Mobile
Source Institutions
In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.

Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.

Reusable Rockets
Source Institutions
This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

Make a Balloon-powered Nanorover
Source Institutions
In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

Ping Pong Ball Shooter
Source Institutions
In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

Silly Putty Investigation
Source Institutions
In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.
