In this activity, learners learn about the adaptations that flowers have developed which support pollination. Learners also list their personal preferences (i.e.

In this activity, "write" a secret message in genetic code as beads on a string.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

In this engineering activity, young learners investigate multi-level buildings.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Students design and create their own air-powered rockets, in this hands-on activity.

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

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

Learners will build and experiment with their own windmills made from simple household materials.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.

In this activity, learners make homemade journals featuring seashell rubbings. First, learners transfer the texture of a seashell onto a piece of paper using a crayon.

In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.
