Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), 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.

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.

Fitness Factor
Source Institutions
In this online activity, learners partner up to complete several physical exercises and assess their starting fitness level.

Statistics: Whirlybirds
Source Institutions
In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

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.

Sand Castle Saturation
Source Institutions
In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

Sawing Away
Source Institutions
In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

Egyptian Measuring
Source Institutions
In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.

Soda Geyser
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

Show Your Colors!
Source Institutions
In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.

Otter Smorgasbord
Source Institutions
In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.

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).

Mixing in Math Moments: Several 5-10 Minute Math Activities
Source Institutions
This website contains several activities. Mixing in Math Moments are activities that take 5-10 minutes that keep learners occupied, learning about the world, and using math on their own.

Ins and Outs of Respiration: Determine your Respiratory Rate
Source Institutions
Learners will determine their respiratory rate and explore the factors that affect breathing rate by filling out and using the Respiratory Chart provided in the lesson.

Exploring Materials: Graphene
Source Institutions
In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

Comparing the Amount of Acid in Different Solutions
Source Institutions
In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

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.

Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Exploring the Universe: Star Formation
Source Institutions
In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.
