# Paper planes

Make some paper planes with your child, and then throw them to see which ones fly the furthest. Which design results in the longest flight length.

## Things you need

• 3 sheets of paper to test different plane designs
• Measuring tools (twigs, pencils, feet, tape measure)
• An open space to fly paper planes.

## The challenge

### Step 1

Help your child fold their paper into three different paper aeroplane designs. Check out some plane designs from the CSIRO's Double Helix.

### Step 2

Mark their throwing position, being sure to give their planes plenty of space to fly.

### Step 3

Ask your child to throw their paper plane as far as they can.

### Step 4

Measure the length of the plane's flight from the throwing mark to the landing spot. Here are some example of the different ways you can do this:

• laying down forks or pencils of the same length
• using a tape measure..

## The conversation

As your child is measuring the distance their planes flew, support them in paying close attention to the accuracy of their measurements. You can talk about things like:

• the importance of measuring in a straight line
• precisely laying out the measuring tools so there are no overlaps or gaps
• the importance of using uniform units (for example, forks that are all the same length compared to forks that are different lengths)
• what other tools could be used
• which plane flew the furthest?
• if the plane flew '28 forks' from the starting point, what else around the house is the same length.
