For our Friday experiment last week, my students entered our classroom to find, silver platters set out with intriguing science tools. They “oooohhhed and aaaaahhhed” at the beauty and uniqueness of each item and could not WAIT to find out what the different ingredients would do!
Each try contained tall glass beakers and jars that I added baking soda to along with pitchers and cups filled with a mixture of vinegar, dish soap, and the secret ingredient was GEL food coloring. Each tray also had pipettes, eye droppers, and spoons. My one rule was that they could not pour the vinegar into the baking soda. (This forced my students to really experiment with adding the different ingredients to each beaker, jar, and glass using the different scientific instruments.)
I had my students make predictions about what they thought was going to happen and then set off to work.
My students carefully began experimenting adding the vinegar mixture to the baking soda mixture and vice versa.
They squealed with excitement as the baking soda changed colors and eruptions began to happen.
The best part of the experiment was that the vinegar mixtures ended up looking quite dull at first. (You can see it in the picture above.) However, once the students added the liquid to the baking soda, the colors miraculously changed! (I added purple gel fooding coloring and pink gel food coloring to the vinegar.)
Once the eruptions started happening, we ended up with multi colored eruptions!
The giggles and experimenting lasted for about 45 minutes in my classroom. My students didn’t want to stop! Each child kept saying, “Miss Smith, this is just SO much fun!!” “I love this!” “Thank you Miss Smith!”
Make sure that you set out trays underneath your beakers because they sure do erupt!
Magic Potions Ingredients Needed:
-gel food coloring
-dish soap (I used blue Dawn dish soap)
For my classroom of 11 students I used 2 full boxes of baking soda and a half a JUG of vinegar. I added a good squirt (maybe a little less than a tablespoon) of dish soap to each cup.
I hope that you will try this experiment. Your students (or children) will LOVE it!!
