What do you do when a chunk of your physical science class is away at the state softball tournament, it's Friday, and you just finished a chapter but don't want to start the new chapter until Monday? You decide to give your students a piece of sidewalk chalk and a measurement lab to keep them busy. Measurement was the last skill in the previous chapter, so it made sense. I promise!
Here's what I came up with:
We began by making our predictions of how much chalk it would take to write our first and last names. When some students were making crazy predictions, a student reminded the class that a paper clip has a mass of approximately 1 gram. This helped make a bit more accurate of predictions.
Next, we took the triple beam balances outside. It was a windy day, and we quickly realized this was a BAD idea.
Some students opted to use a triple beam balance in the classroom.
Others chose to move their triple beam balances into the hall to work.
Here are some pictures of my students in action:
