Let the air out of the balloon. You can now use these balloons in a science experiment, put them in a homemade valentine cards, or set them on your child’s plate for a fun surprise on Valentine’s Day.
Valentine’s Day Activity
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.
Valentine science experiments
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! When you are ready to reveal the message with a fun valentine science experiment, put a balloon over the opening of the bottle (so it fits tighly). Now the balloon straight up so all the alkazeltzer falls into the bottle, let go, and watch what happens!
Valentines Day Activity
A chemical reaction is taking place as the alka seltzer tablets hit the water, carbon dioxide is released. The air needs to go somewhere so it will push out towards the balloons and fill them up – inflating the balloons.
Valentines Day Activities
Kids of all ages will be impressedas they watch the balloons fill up like magic, all on their own. Explain to them how the chemical reaction in this chemisty science experiment for kids has made the balloons swell up with air – carbon dioxide.
Kids will be excited to see the secret messages appear with notes that may include their names, be mine, i love you , hugs and kisses, XOXO, etc. This is such a simple and fun heart science experiment everyone should try!
