How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

In this activity on page 3 of the PDF, learners investigate how much sugar is in a soda. Learners use sugar cubes to measure and calculate the amount of sugar in a bottle of soda.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

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.

In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

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

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.
