Week 26 of Pre-K

Bible Verse: Love is patient, love is kind. It does not envy, it does not boast, it is not proud (1 Corinthians 13:4).

This week J reviewed time to the hour, half hour and quarter hour. She worked on counting money - pennies and dimes. She also worked on numbers through 100.

Explode the Code
Reading, writing and spelling skills

Jenni enjoys spelling with Bananagrams.

Color Symphony

 Supplies: a flat baking tray, food coloring, whole milk, liquid soap

1. Pour milk into the tray so it covers the bottom
2. Add 6-8 drops of different colored food coloring onto the milk in different spots
3. Add 5 drops of liquid soap onto the drops of food coloring and watch the show!

How does it work?
When you drop the liquid soap onto the tray, it tries to break down the fat in the milk. While it is doing this, it causes the colors to scatter and mix creating a very colorful display.

Chemistry Cleans a Penny

 Supplies: a few old pennies, 1/4 c. white vinegar, 1 t. salt, plastic bowl, paper towels

1. Pour vinegar into the bowl and add the salt - stir it up
2. Put 5 pennies into the bowl and count to 10 slowly
3. Take out the pennies and rinse them out in some water

How does it work?
The vinegar is an acid, and the acid in the vinegar reacts with the salt to remove what chemists call copper oxide which makes pennies dull.

Jenni did a lot of painting this week.
