As we get down to the last couple weeks of school, I find my kiddos bored with movies and overwhelmed with final exam study guides. To remedy both situations, I have planned a week full of fun science experiments that include ingredients commonly found in our kitchen. Here’s the schedule for the week (pictures to be posted as we go!) :
Tuesday: Giant Bubbles
Today I mixed up two batches of homemade bubble fluid:
Giant Bubbles – 6 cups water, 1/2 cup dish soap, 1/2 cup cornstarch, 1 Tablespoon baking powder (not soda!)
To make bubbles: Add all ingredients in a bucket and stir gently until dissolved/combined, trying to not make bubbles in the mixture
Indestructa-bubbles – 6 cups water, 1 cup corn syrup, 2 cups dish soap (Joy was recommended)
To make bubbles: Combine water and corn syrup in a bucket and stir until combined. Add soap and stir gently.
We used a whole bunch of kitchen tools as bubble wands to make all sorts of different bubbles!
I’d post a video, but there are video wavers necessary for that…
Wednesday: Soda Geysers
The kids and I watched a video by Steve Spangler and will be replicating this experiment with a few changes.
– 1 two-liter diet coke
– 5 mint Mentos candies
– A hammer
– A screwdriver or nail
– A large paperclip
Unscrew the cap of the Diet Coke and set aside. Drain out about 1 cup of Diet Coke. Drink!
Using the hammer, carefully punch a small hole in the top of the diet coke cap.
Push extra wire of the paperclip through the inside of the cap. Bend the paperclip so that it is holding onto the outside of the cap.
Carefully replace the cap onto the Diet Coke. The Mentos should not be touching the top of the cola. If it is, drain some more Diet Coke out of the bottle.
When ready, unbend the paperclip, letting the Mentos-clip drop into the Coke.
Hold the bottle pointing away from you and watch the geyser happen!
Thursday/Friday: Solar Oven S’mores
