In this quick activity (page 1 of PDF under SciGirls Activity: Hockey), learners will use a simple physics of motion and gravity demonstration to test their predicting skills.

In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

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.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity, learners conduct the "Stroop Effect" test and explore what happens when they try to complete two simple tasks at the same time.

In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

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.

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.

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
