Science for Kindergarten

For the next few weeks I'll be in planning mode for Kindergarten. We won't start until January but I won't have much time for planning in November and December so I figure I'll get things ready now. At the moment I'm working on plans for science. TJ loves to do experiments but I certainly don't want to add any heavy work to our schedule (after all, it is only kindergarten). The plan is to keep it light and fun.

I bought Sonlight Science K (just the experiment book, dvd, and kits). I think I might have to hide this stuff from TJ because she keeps pulling things out and tells me she's "doing science". I plan on alternating the experiments with nature walks and lots of science books from the library. We aren't doing every experiment listed on the dvd, just the ones that I thought would be interesting to TJ (she might have other ideas and want to add some of her own!).

Between that and our weekly nature walks I think we'll cover plenty of science this year. If you'd like to take a look at our plans they are posted in the sidebar.

Making Rainbow Sugar

Last week's science experiment was about evaporation. TJ made sugar water and used food coloring so it would be easy to observe. Over a period of three days we watched it's progress.

Here is the sugar water just after adding the red food coloring


Two days later - it was thicker and syrupy


Three days later - success!


It was a fun experiment. TJ would ask every morning if we could check on the sugar. She had fun with this one - I highly recommend it!

To do this experiment with your child - mix 1 spoonful of sugar with about 5 spoonfuls of water until it is completely dissolved. Pour onto two foil covered dishes and add some food coloring to each dish. Leave it in a warm place for three days, observing it daily to see how it changes. Have fun!

Fizzy Raisins

For this experiment you'll need 7Up or another type of clear soda, a glass and a few raisins. Pour the soda in the glass.


Drop the raisins into the glass.


As the bubbles form on the raisins the gas slowly carries the raisins to the surface of the glass.


Some of our raisins took awhile to float but it was lots of fun to watch the bubbles form and carry them up.

Invisible Ink

This is a really fun project! You'll need a lemon (cut in half), some notebook paper, an iron, a surface to iron on, and an adult to do the ironing. :)

First, have the child "finger paint" with the lemon by rubbing their finger on the surface of the cut lemon and then write a secret message or draw a picture on the paper.


After the drawing has dried and the picture is invisible, have an adult use a hot iron to reveal the secret message. This could take a bit of time so be patient! Eventually the lemon juice will turn brown from the heat. TJ had lots of fun with this experiment.


 Freezing & Melting

Before I get to our experiment this week I've just got to say how much I love Sonlight science! We've had so much fun doing these experiments. I didn't buy the whole kindergarten kit, just the InquisiKids DVD, the supplies, and the corresponding experiment book. TJ loves doing science. When she was recovering from a cold last week I let her pick a movie to watch. She asked to watch her science DVD and would yell for me to come in every time the experiment was one we had completed. :)

Our experiment this week was to discover which food items would freeze and which would not. We (even Nick got into the fun with this experiment) filled a clean ice cube tray with various food items such as butter, oil, peanut butter, ketchup, syrup, juice, etc.

We put a spoonful of each item in the ice cube tray and then put the tray into the freezer. I meant to take it out later that day but we forgot about it! Two days later, when I remembered we had it in the freezer, we pulled it out to check out what happened.

This was the fun part - we got to stick our fingers into each food (very sticky and messy!) to find out how the cold temperature of the freezer affected each item.


Here's a picture of TJ discovering that the freezer didn't affect our peanut butter. TJ also discovered that the freezer didn't have any effect on oil, jam, honey, chocolate syrup, dulce de leche, or dish soap. Very fun experiment!
