Activity: Lemon Boats for Bugs
At camp this week, the gang made a bunch of different vegetable boats built for bugs. Let’s make lemon boats and see if they float!
- Lemons (limes or a melon or anything else with a thick skin works well too)
- Small sticks
- Water (for testing)
Step 1: Cut your lemon in half and hollow each side.
Step 2: Insert your stick into one empty hollow of a lemon half.
Step 3: Make a paper sail and attach it to the stick.
Step 4: Once your bug boat is in ship shape, fill a sink or tub with water or bring your boat to a pond to test it! Does it float?
What in the WOW is going on?
Objects float when they are less dense than the fluid they are in. If you dropped a tennis ball and a marble into a bucket of water the marble would sink and the tennis ball would float. This is because a tennis ball is full of air ( it is not very dense ) and a marble is solid ( it is very dense ). Huge ships float because although they are extremely heavy they have a lot of empty space inside. Lemons float because they have lots of air pockets in the thick skin
