Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

Slide Whistle
Source Institutions
In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

Super Sleuths
Source Institutions
In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

Burning Questions About a Candle
Source Institutions
In this activity, learners will observe a deceptively simple process: a burning candle.

Make a DNA Model
Source Institutions
In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

Aviary Architect
Source Institutions
In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

Cooking With the Sun
Source Institutions
In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

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

Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

Anti-Gravity Chamber
Source Institutions
In this activity, learners will use magnets and household items to create a structure that allows paperclips to appear like they are floating.

Simple Machine Challenge
Source Institutions
In this activity, learners are challenged, using everyday objects, to create simple machines to complete specific tasks.

Dough Creatures
Source Institutions
In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.
Transparent Gelatin
Source Institutions
In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.

Shake and Make: Charge Recognition
Source Institutions
In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
