Science: Falling Letters Experiment (Weight)

One of best ways we’ve found to do science experiments with kids is to focus on cause and effect. It’s easy to discuss reactions and what the kids think of them!

Our science experiment for Chicka Chicka Boom Boom has to do with how much weight a bridge made of a piece of paper can hold.

Here’s what you need:

  • Bag (or gallon ziploc bag with strings tied like handles. 🙂 )
  • Alphabet items (we used blocks, but you can use anything semi-heavy with letters on them!)
  • 2 chairs
  • 1 sheet of paper
  • tape

Experiment: How many blocks can a rolled piece of paper hold?

Have each student guess a number and then start adding your blocks– be sure to take advantage of the opportunity to practice letters and sounds!

  1. Make a paper bridge
  2. Hang bag on paper bridge and put between two chairs
  3. Add blocks one by one until the bridge crumbles!

Who guessed the right number?
