“Bubbles! Exploding Bubbles!!!”
This was the scientific observation my year 2 year old while completing this super sensory experiment. Not only a fun way to watch cause and effect but the use of the eye dropper qualifies this as fine motor skill practice.
Supplies you need to have on hand to create fun bubbles that also count as a science experiement:
• Baking Soda (a whole box)
• Eye Dropper
• Food Colouring
• Cloth for spills/explosions
• Tray, Baking Sheet with a ridge is perfect
• Muffin Tray
Start by sprinkling a fair amount of baking soda all over the baking sheet so it’s nicely covered.
Put vinegar in about 6 of the muffin sections, about half way full. Add various colours of food colouring to the vinegar sections, one colour per area.
Suck the coloured vinegar up in the eye dropper by pressing the eye dropper into the vinegar. Then deposit the vinegar into the baking soda hills.
POOF! Bubbles will group up and spill around the tray like a mini volcano. Your child will delight with excitement that their action just created this response!
Likely your child will love to do this over and over and over, measuring the results in their mind. Does the blue “water” do anything differently than the red? Ask them probing questions to encourage experiementing actions (ie: If you put more vinegar do you get bigger bubbles? If you add more colours does it change the explosion? How?)
As long as your child can maneuver the eye dropper well, this is a great activity to keep busy for a long time. Perfect for the kitchen table while dinner prep is happening and you can watch over but not do it for them.
One piece of warning – stay out of the baking soda! It tastes gross and has a messy flour-like consistency if it’s made a mess of. If you’re anti-mess you may wish to discourage your child from raking their hands through their finished product (like mine did…) as the mess will be a combination of powdery and also sticky from the vinegar.
If your child loves the 'exploding' effect, try creating baking soda and vinegar "Volcanoes" together. All details and instructions here.
