We know that the 100th day of school is becoming a biggeR and biggER celebration in elementary schools, and this bulletin board knocks it out of the park!
It's a relatively simple concept...students look at 100 in so many ways on this day, why not with sound, too?
Inside each of the little milk bottles is a different item--100 of each. They have been hung on the board so that students can explore the sounds that are made by the different items.
Not only do I love this for its fabulous STEAM connection, I love it for all of the possibilities it offers us...
For example:
What if you marked the 50th day of school with a container of items, would it be half as loud as a container with 100 of the same item on the 100th day? What changes?
Looking down into the container of 100 thumbtacks, what is your estimate for how many thumbtacks the container will hold?
How will changing the container change the sound of the item?
If we dumped out the items in one of the containers, what are some different ways that we could count them that would help us in the event that we lost track of our count?
If you had 100 paperclips on the 100th day, and you created another bottle with 100 paperclips but you added a clip for each day after the 100th, how many days would it take for the sound to be distinctly different? Would it be different?
Why do we mark 100 instead of 90? 90 is the halfway point of the year? What fractional part of the year is the 100th day? What do containers with 90 items sound like?
What uses can you think of for this idea? Share in the comments below!
One thing I have suggested to the students is to guess which would be lighter and which would be heavier before they try them.
