This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

The demonstration/experiment provides quick proof that air has mass.

In this activity (page 2 of PDF under GPS: Kinetic Sculpture Challenge Activity), learners will predict which objects have to overcome the most static friction to slide down a ramp.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners experiment with gear motion to understand how gears work to change the amount of force, speed, or direction of motion in machines.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.
