This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

Learners develop an understanding of air pressure in two different activities.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

Learners build devices from rubber bands to test for invisible air pollutants.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

This lesson focuses on graphene and its electrical properties and applications.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.
