Density Rainbow
Source Institutions
In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
Gel Electrophoresis of Dyes
Source Institutions
In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.
Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.
Paper making: a craft and a chemical engineering major
Source Institutions
In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.
Taking Its Temperature
Source Institutions
In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Portable Potable Pressure
Source Institutions
In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.
What's the Matter
Source Institutions
In this activity, learners identify different classes of matter based on physical properties.
Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
Test Your Lung Power
Source Institutions
In this activity, learners try to blow up a balloon hanging inside of an empty bottle.
Inflate-a-mole
Source Institutions
In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.
Electrostatic Water Attraction
Source Institutions
In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.
Suminagashi: Floating Ink Paper Marbling
Source Institutions
In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.
How Small Can You Cut?
Source Institutions
In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.
Does Your Chewing Gum Lose Its Flavor?
Source Institutions
Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.
Ramps 2: Ramp Builder
Source Institutions
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.
Make a Salt Volcano (Lava Lite)
Source Institutions
This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
Drip Drop
Source Institutions
In this water activity, learners explore how water drops behave on different surfaces.
Mass of the Earth
Source Institutions
In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.
Cartesian Diver
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.
Speedy Shelter
Source Institutions
In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.
