Our Year 3 scientists have been putting their strength and measurement skills to the test in a hands-on investigation all about grip strength.

To figure out how the size of an object affects how tightly we can hold it, the children worked in teams to investigate a range of PE equipment.

Here is how they cracked the science behind the squeeze:

  • Measuring Circumference: First, they carefully used tape measures to find the distance around different PE balls—from tiny tennis balls to chunky basketballs.

  • The Grip Test: Next, they tested how easy or difficult it was to securely grip each ball with one hand.

  • Analysing Data: They compared their measurements to see if a larger circumference made it harder to maintain a strong grip.

There was brilliant mathematical thinking, fantastic teamwork, and plenty of determined faces as they tested their theories.
