Science At Play: Column Contest

We have a contest you can try with anyone in your family over the holidays. Grab a piece of paper, some tape and a few heavy books. Then, challenge your family to see who can create the strongest column out of a single piece of paper. Watch below to see who created the stronger column- Aoife or Jessie. What’s your guess?

Materials to Collect

  • Construction paper or cardstock
  • Tape
  • Books

Try it!

  1. Fold your sheet of paper into a column shape that you think will be able to support the most books. Use tape if needed to hold the shape.
  2. Slowly stack books on top of your column until it gets crushed.
  3. Try building differently shaped supports to figure out what shape is the strongest!

What is the Science? 

You might have noticed that some shapes worked better than others in the column challenge. The shape of the column determines how many books it can hold up because different shapes spread out, or disperse,  weight differently depending on how many corners they have. The corners on the columns hold more weight than the flat sides do, so the square column collapsed under only a couple of books because its four corners couldn’t carry the weight and crumpled. However, the cylindrical column spreads out the weight of the books evenly across the entire column – you can think of the round shape as a TON of tiny corners! That’s why the cylindrical column is able to hold up more books. 

Since cylinders are an excellent shape for dispersing weight, you might notice a lot of cylinder-shaped columns holding up buildings. Even a tree trunk is cylindrical, holding up the weight of all of the leafy branches above it. See how many cylinders you can find holding up weight as you go about your day!

Ask Your Young Scientists

  • Which shape structure was able to hold the most books?
  • How does a triangular column compare to a hexagonal (6-sided) column?
  • How many different shapes can you test?
