In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.

In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

Learners follow a three-step process to start their own rock collection.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

This lab activity has learners create a pendulum with a one-second period.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this math game, learners try to earn the most points by winning stacks of four dice. Learners practice number recognition and addition skills.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
