In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.

In this activity, learners investigate the olfactory system by conducting several experiments.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In the kitchen, learners can perform their own density investigation.

In this activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

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 test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.

Learners use a simple process to extract DNA from strawberries.

In this activity, learners cook amino acids and sugar to explore the range of aromas released.

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?
