Big Question

Are our feet bigger than our heads?

Ask the children:

• Put your hands up if you think your foot is bigger than your head.
• Put your hands up if you think your head is bigger than your foot.
• How could we find out?

Explain:

"Scientists don't just guess. They test their ideas and collect evidence."

Discuss and Predict

Ask:

• Is my hand the same size as my foot?
• How could I find out?
• Is my foot as long as my head?
• What could I use to compare them?

Model making a prediction:

"I predict that my foot will be bigger than my head because..."

Children share their predictions with their talk partner.

Working Scientifically

Scientists can:

• Ask questions.
• Carry out simple tests.
• Observe carefully.
• Compare and measure.
• Record what they find out.

Main Activity

You Will Need

• 2 sheets of paper
• Pencil
• Scissors

Instructions

Step 1: Measure Your Head

With support from a partner or adult, wrap a strip of paper around your head.

Cut the strip to that length.

Step 2: Measure Your Foot

Cut out the foot shape.

Step 3: Compare
