Exploring Measurement
Source Institutions
In this "Sid the Science Kid" activity, learners use their bodies to measure a room. Instead of inches or feet, how many kids does it take to measure the length of a room?

Super Spinners
Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Balloon Hovercraft
Source Institutions
In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

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.

Pre-School Ball Run!
Source Institutions
In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

Sort It Out!
Source Institutions
In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

Sizing Up Temperature
Source Institutions
In this activity, learners explore Charles' Law in a syringe.
Soaring Towers: Building with Recycled Materials
Source Institutions
In this activity, learners will build the highest tower they can out of recycled materials.

Air Cannon
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

Servings and Choices
Source Institutions
In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

For the Birds: Environmental Effects on Population
Source Institutions
In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

Sugar Crystal Challenge
Source Institutions
This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

Make a Model of a Home Made From Shipping Containers
Source Institutions
In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
Is It Possible: Estimating Measurement
Source Institutions
In this activity, learners will decide together on a question about how far, long or high the group could reach together.

Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.

Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.

Our Sense of Sight: How We Perceive Movement, Depth and Illusions
Source Institutions
In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

Building Tall
Source Institutions
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.
