Inside each balloon put an alka seltzer tablet. HINT: You may need to break art the tablet to get it to fit – don’t worry it will still work just fine!

Now is a great time to ask students what they think will happen. We like to use these scientific method worksheets to encourage kids to think scientifically about the experiment – make a hypothesis, write down their procedure, and record their observations.

Fill up a clean bottle 5/6 of the way up with water. We added food coloring to add to the excitement of this activity and asthetics, but it is not necessary!

Now the balloon straight up so all the alkazeltzer falls into the bottle, let go, and watch what happens!
