Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Automotive Emissions and the Greenhouse Effect
Source Institutions
In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Build a Giant Puzzle!
Source Institutions
In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

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?

Balloon Nanotubes Tabletop
Source Institutions
This activity introduces learners to the structure and properties of carbon nanotubes.

Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

Egg-stra Strength
Source Institutions
In this physics activity, learners will investigate the strength of egg shells.

The Effects of Acid Rain
Source Institutions
In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

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.

Neato-Magneto Planets
Source Institutions
In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model

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.

A Closer Look at Crystals
Source Institutions
In this activity, learners compare different types of salt crystals under a magnifying glass.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

There’s Oil in My Eggs
Source Institutions
In this activity, learners investigate the impact of oil pollution on the environment and wildlife. Learners use hard-boiled eggs and feathers to understand the damage that oil spills can cause.

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

Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.

Soggy Science, Shaken Beans
Source Institutions
Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

Exploring Materials: Graphene
Source Institutions
In this activity, learners investigate the properties of graphene and graphite.

Dancing Cereal
Source Institutions
In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static
