Find Someone: Use Math to Learn About Friends
Source Institutions
Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

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.

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.

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
Mystery Jars: Estimate Contents
Source Institutions
This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

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.

Science Cooks!
Source Institutions
In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

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.

Breathing Room
Source Institutions
In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.

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.

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.

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.

Using Different Models of Earth
Source Institutions
In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

Sea Turtle Populations
Source Institutions
In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.

Bean Bugs
Source Institutions
In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

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.
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.
