In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

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

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

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

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

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 activity, learners add squares to paper dominoes to make polyominoes.

In this math puzzle game, learners work together to use algebraic reasoning and fun clues for solving word puzzles.

In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

Learn about friction and kinetic energy with this cool spinning toy.

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.
