Experiments
Who Sank the Boat? by Pamela Allen
This is a cute book about trying to figure out which animal sank the boat. We will use this book as a basis for some boat experiments.
I found this kit last summer in a Goodwill. It contained most of the items needed for simple experiments to complete around the house. We will be using these experiments today. (not a good pic, sorry)
Experiment #1
I found three different types of boats that the kids use for their water play. After reading our book, I asked J to determine how many marbles would sink each boat. I wrote down her answer and then we tested her hypothesis.
The one boat that surprised us was the blue boat. She guessed that it would be 12 marbles to bring it down. It was actually 28 marbles!
Experiment #2
Does it dissolve in water?
We discussed what it meant to "dissolve" - breaking into pieces so small that you can no longer see it. I gave her a tray of 5 items (coffee grounds, sugar cubes, rice, flour, and oatmeal) and J expressed which items she thought would dissolve in the water. Then we did the experiment!
J actually thought the coffee grounds would dissolve but we found out differently. She was correct on the other items though.
Experiment #3
What happens when you mix baking soda and vinegar?
I gave J a container with some baking soda, two cups of vinegar with some food coloring, and an eye dropper. The look on her face says it all....she had fun with this one.
The baking soda and vinegar react with each other providing an excellent assortment of fizzing and such. She worked through the entire dish of baking soda, mixing colors as she went.
Experiment #4
What do we get when we add Kool Aid and sugar in water?
Okay, this isn't really an experiment but my daughter hasn't had Kool Aid before. I found these packets of the drink mix that I had been waiting to use. I decided to use them since we are getting ready to go to 'Merica.
She mixed up some strawberry Kool Aid and loved it. Experiments were fun and easy to do. We are off to the next letter....counting down to the end of the school year. It will be here before we know it.
