Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

Up, Up, and Away
Source Institutions
In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

Zoo Calendar
Source Institutions
Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

Rabbit Olympics
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Rabbits) is a full inquiry investigation into observing, recording, and graphing animal behavior.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

Count Around
Source Institutions
Learners explore their surroundings while reasoning about categories and counting.

Dispersing Dispersion
Source Institutions
In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

Size, Mass, Area, and Volume
Source Institutions
In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

Echolocation Lab
Source Institutions
In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

Look Mom, No Wings!
Source Institutions
In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.

Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

Invisible Investigations
Source Institutions
Using indirect observational methods, learners distinguish between charged and uncharged objects.

How Active Are You?
Source Institutions
In this activity, learners explore what is and is not active play and how it contributes to a healthy body and mind. Making active play a routine part of every day is a key concept of the experience.

Super Soaking Materials
Source Institutions
In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Probability: Rock Around The Clock
Source Institutions
In this math lesson, learners apply the Monte Carlo method of simulation to determine a reasonable estimate.

Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.
