Summer of Science Part Two

Lately we've been learning about matter and how it can change.

I introduced L to the three states of matter with this tray.  We talked about how matter is anything that takes up space and how it can be in three different states.  Once we discussed this L looked around the house to first find solids and then liquids and breathed in lots of gas (air : ).  It's wonderful to see the delight in a child when they first discover something new and the whole world opens up to them.  L was excitedly running around the house pointing to things and saying "my shampoo is a liquid, milk is a liquid....."

We then talked about how some things can be all three states at different times.  We used water for our example.  L is examining a glass with water in it, ice cubes and the steam from boiling water.

We've also been talking about reversible change and irreversible change.  L could see and experiment with how water can change into ice when frozen and then melt back into water when heated, which is an excellent example of reversible change.
We saw an example of irreversible change when we did the "heat" experiment with apples.

We also did an experiment on decay and talked about how all living things will eventually die then decay and turn back into soil.  This led to some interesting discussions as you can imagine but I tried to keep it light and scientific.
We took a large piece of watermelon that had been in the fridge for a while and did an observation of it.  L drew a picture of it in her science journal and we dated it.
Here it is a week later.

Here is L doing her second observation in her journal and noting the changes.  She didn't last very long out there as there were too many wasps and she retreated to the kitchen periodically going out to "observe" from the deck.
We left it out there until it was so small and shrivelled that we just dug it into the soil.

Our weather has been the pits this summer so it's been and ideal time to do all of our science projects.  Before I found Sid the Science Kid I have to admit that I was really unsure of how to introduce science to L but the show has made it super simple and tons of fun.  I also have a wonderful book of 101 Science experiments that we will move on to soon.
