In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

Historically, sea floor mapping (bathymetry) was done by soundings.

In this activity, learners construct a home-made journal with simple, everyday materials.

Using simple, inexpensive items, learners build and test submarine models.

This activity was designed for blind learners, but all types of learners can use it to learn to differentiate between qualitative and quantitative observations and to practice data collection.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In two separate bags, learners mix water with Epsom salts and detergent.
