Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

Urine the Know
Source Institutions
In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

Solve The Fall
Source Institutions
In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

Exploring Size: Powers of Ten
Source Institutions
In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

Exploring Size: Measure Yourself
Source Institutions
In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

Yogurt Cup Speakers
Source Institutions
Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

Not Just A Bag Of Beans
Source Institutions
In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

Paper Airplanes
Source Institutions
In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

Home Molecular Genetics
Source Institutions
In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

Rotational Equilibrium
Source Institutions
In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.

Bird Feeder Challenge
Source Institutions
In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

Balloon Rockets
Source Institutions
This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.
Soaring Satellites
Source Institutions
Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

Echo Base Bobsleds
Source Institutions
The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

Submarine: Lift Bag Lander
Source Institutions
In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.
