Staff Favourite: Emma

Hello TTK Families!

This week we are bringing you the second installment of our new blog series – staff favourite activities!

Next up is… Emma!

Emma has been working with TTK now for just over one year, having joined us in October of 2019. Even though she’s only been here a short while, she has subbed at most of our Richmond centres! She started out at McKinney, then worked from home through the spring creating content for our youtube channel, at Westwind through the summer and you can now find her again at McKinney in the afternoons.

One of her favourite activities to do, no matter where she is working, is any science experiment that involves an acid-base reaction. While baking soda and vinegar is likely the best known combination, Emma prefers to use lemon juice – it smells way better! She loves to see the kids’ reactions when the mixture bubbles up and “explodes.”

Try this reaction at home!

All you need is:

• • • Lemon Juice (1/4 cup)
    • Baking Soda (1/4 cup)
    • An empty water bottle
    • A balloon
    • A funnel (not necessary, but helpful!)

Directions:

1. 1. 1. Pour the lemon juice into the water bottle.
      2. Using the funnel, spoon the baking soda into the balloon.
      3. Pinching the balloon closed, attach the opening to the top of the water bottle, being careful not to let any of the baking soda fall.
      4. When you’re ready, lift up the balloon so the baking soda falls into the lemon juice.
      5. The baking soda will react with the lemon juice, producing CO2, and slowly inflating the balloon.
      6. For a bigger reaction, use a larger bottle and increase the amount of baking soda and lemon juice!
