Eruptions

When visiting a friend yesterday her son requested a volcano.

She pulled out a cookie sheet for each child, loaded them up with goodies and placed them in front of them.

Rose was delighted. She was taught to ‘suck up’ the vinegar and ‘push it’ out of the dropper.

The two wee cups contained vinegar with a few drops of blue food colouring and yellow food colouring. This was Rose’s first time playing with these ingredients. She loved the chemical reaction but was quite contained with the dropper. No crazy mess, as I had anticipated.

Jasper is an expert eruption maker and loved telling me about making hot lava and warning me to be careful not to get burnt.

Rose lasted about 5 minutes then was done playing. Jasper continued and has been known to enjoy this activity for over 30 minutes.

The two colour choices allowed the children to make green, teaching colour mixing through exploration.

Thank you for a great activity Erinne (after Rose was finished… I played!)

Learning Opportunities:

  • describe the chemical reaction (carbonic acid is produced which immediately falls apart into water and carbon dioxide- hence the bubbles) Simply using the word ‘reaction’ at age 2 is exciting!
  • colour mixing (you can use various colours)
  • fine motor skills, using a dropper
  • experiment with patterns and design

Investigating Why Snow Melts

The gorgeous white fluffy stuff is finally here. Many Manitobans sigh and feel blue about the incoming winter, but I love it. Everything, from the excessive amount of clothes needed, to the tobogganing and freezing nose hair!!!

Daisy and I went out to play after daycare one night and got chatting about the snow and how it was still melting during the day. This sparked a need to find out how we could slow down the melting process. The picture above is Daisy collecting some snow to bring indoors (don’t worry, she has been told not to eat yellow snow).

Equal amounts of snow were put in bowls.

One was put in the fridge.

Another had an ice cube added and was left on the counter.

The third was also left on the counter.

The ice cube and fridge were Daisy’s ideas and the third is a control.

We guessed (hypothesized) about how long they would take to melt.

You can just see a little ice cube after 1 1/2 hours. The control was just water but we were very excited to find the snow in the fridge was still snow.

Learning Opportunities:

Science:

  • Set up an experiment
  • Form a hypothesis
  • Explain results

What will you do with the abundance of snow we are about to get?
