Science Sunday - Friction
I am using Teaching Physics With Toys as the basis for our unit. This book lays out the activities as experiments and truly promotes inquiry the way I feel science should be approached. I picked up the book based on a recommendation from Traveling Jews. So many of the activities and curriculum we use come from recommendations out of my blogroll. However for this particular activity I used Science Fun with Toy Cars and Trucks. This book is written to be read by children and Froggy picked it up and asked to do some of the activities. It is not inquiry based but I have modified tthis activity for an inquiry approach.
To give Froggy some background and ideas to pull from before presenting anything, we read Magic School Bus Plays Ball. For our first lesson, I made a car out of a milk carton.
It did not go far. We made several trials. It went approximately 90cm. Then I asked her what we could do to make it go farther. Her immediate answer was "Rapunzel can help me." We tried that because she wanted to even though neither one of us really believed it would help.
me - "What makes the riding toy move so much better?"
Froggy - It has wheels!! Can we give the box wheels?
me - we sure can
We again made several trials with the wheels. The car went about twice as far at 170 cms.
