Ice Roads: Steiner Trees
Source Institutions
In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

Propeller-Powered Car
Source Institutions
In this activity, learners construct cars that are powered by hand-made, electric propellers.
History of Siege Weapons
Source Institutions
In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency

Cable Car
Source Institutions
In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

Bouncing Yo-Yo
Source Institutions
In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

Starch Breakdown
Source Institutions
Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

Size Wheel
Source Institutions
In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

Exploring Forces: Static Electricity
Source Institutions
In this activity, learners investigate what happens when you build up static electricity on plastic balls.

Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
MarsBound!: Mission to the Red Planet
Source Institutions
MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.

Flubber
Source Institutions
Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

Planet Exploration Mission
Source Institutions
In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Exploring Size: StretchAbility
Source Institutions
In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

Exploring Structures: DNA
Source Institutions
In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

Information Hiding: Sharing Secrets
Source Institutions
This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.

Bookshelf
Source Institutions
In this activity, learners use simple tools to build a bookshelf with a built-in bookend.
