In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

This is an activity about friction as well as kinetic and potential energy.

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

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.

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

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

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

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.

In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.
