Surface Area and Soda Geysers
Source Institutions
This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

Testing Falling Peanut Butter Sandwich Myth
Source Institutions
In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

Above Water: Buoyancy & Displacement
Source Institutions
In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

Moving Model Glacier
Source Institutions
In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

Dye Detective
Source Institutions
Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

Cookie Surface Area
Source Institutions
This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

Spot the Sunspots
Source Institutions
In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.

Size and Scale: Probing and Predicting
Source Institutions
In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

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.

Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.

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.

Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

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.

Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

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

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.

Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
