Today I was busy with creating more goodies for my science centers. These are sensory cards. So far I have made the colors, (I forgot to put green in the picture) some of the shapes and a few other categories. I am hoping to add other categories like hard/soft, rough/smooth, birds, reptiles, mammals, fish, fabric, plants……I could go on forever thinking up new categories. I made the cards with cardboard and random items that I had around the house. It was a great way to use up bottle caps, marker caps, twist ties, rubber bands etc. I might have this as a lesson for the kids to create their own cards to take home. It is a good lesson on recycling too.
This next experiment was a little tricky. I made some crystals with alum and water. I am not sure if I got the ratio wrong or the water was not hot enough. Anyway, the crystals are cool. I would need to figure out where I went wrong before we would do this in class. The bigger one is about an inch and a half.
I read about putting Ivory soap in the microwave and having it expand and turn into cool shapes. I had to try it. It expands to cover the plate. It shrinks a bit when you take it out of the microwave. I probably could have made it even bigger but I didn’t want it to burn. If you try this only use IVORY soap. It was fun but not a school activity. I will try this with my niece and nephew though.
The last two are mini marble mazes that I made from recycled materials. The little butterfly picture is a “bumper” made from one of those plastic pull tabs from a juice container. The marbles bounce pretty well off of them. The second one has a little hoop in the top left corner and you go through it before you reach the hole. Another fun and creative activity.
