Rocks and a Scale

This week we did this--





And we recorded our observations--

A magnifying glass with an eye!
Getting each number as a rock is added.
"Wait! What was that last number?"
"Look how much it is!"
We wrote some big numbers.
(How can you offer opportunities for your child to record their observations, thoughts, and ideas?)

And we expanded our experiment--




And we learned what "ERR" on the scale means.

(It means "error" as in "that's too heavy; take something off!")


P.S. - You can still play the "Pay It Forward" game and get some Nashville/Tennessee stuff. Comment on this post.

  2. Don't you just love those digital scales! We have both the electronic one and a balance scale. Sometimes it is fun to have both of them out to compare. I have noticed that the children tend to stay engaged longer with the electronic one, but they really do like the visual of what is heavier with the balance scale too.

  6. This gives me some great ideas to use in story time. Although I work with young kids, a lot of my science/math demos are really designed to get the parents and kids excited about trying things at home. I might weigh different fruits and veggies when I do a food theme or weigh the beanbags that we pile on the teeter-totter... thanks for the post!
