The Theme for the month was Ready for School and the Sub-Theme is Learning Together.

After all the help the children needed last week with hanging all their artwork. I decided to focus on building their hand muscles with some fine motor development activities. To kick the week off and get the kids pumped I started with a little science.

Hidden Color Eruptions. Fine motor skill development

This activity helps them to understand that for every action there is a reaction. They were delighted to see the reactions from this mixture.

What I used for this activity:

  • Baking soda
  • Vinegar
  • Water
  • Droppers
  • 11 Clear plastic cups
  • spoon
  • Gel food coloring
  • Tray

Prep:

  1. Place 1-2 scoops of baking soda in the bottom of 9 cups.
  2. Add food coloring on top of the baking soda.
  3. Add more baking soda to cover the food coloring.
  4. Fill the last two cups with half water and the rest of the way with vinegar.
  5. Place the nine cups of baking soda on the tray.

Presenting the activity.

  1. I walked the tray to the table and we talked about what they thought was in the tray.
  2. I allowed them to try the work without any instructions first to see; if they could figure it out, who had an idea of what was needed to be done.
  3. After seeing that two understood what to do without any instructions I stepped in. I showed them how to squeeze the dropper to gather liquid and how to release the liquid.

What did I observe during this activity?

The kids became really giggly as soon as they saw some fizz action happening. There were ones who were finding this activity difficult and the ones who could do it would help them. Once they discovered all the colors they began to mix them. From that point on they just mixed until all the cups were brown. I saw a lot of peer collaboration during this activity. The conversations that they were having on how to get me to let them have more time with the activity, as well as more cups of hidden color volcanos, was awesome to see.

What would I do differently next time around?


I will have more cups prepared for the time when they ask for more, I would like to try taller cups, try plain water first for teaching how to use the droppers.
