Have some fun with a very simple but engaging measuring lesson by getting the kids to measure the weight of citrus fruit:

• Weigh the orange whole
• Weigh the orange cut in half
• Weigh the juice once juiced to see the difference it weighs
• You could go further and learn about the amount needed for a cup, ½ cup, and ¼ cup
• At the end they get to drink the juice

What you will need:

• Citrus (oranges, lemons, grapefruit)
• Scales
• Juicer
• Jug
• Pencil and paper to write the results down
