In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

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.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this activity, learners make a barometer, an instrument to measure change in air pressure.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this exercise and nutrition activity, learners will explore how food is the fuel that powers them. They will create a chart to figure out how many calories they burn during recess.

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 yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this nutrition activity (page 3 of the PDF), learners will record their food consumption for one day, and then evaluate how their actual diet matched up with the recommended diet.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).
