This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.
