Coin Experiment

Coin Experiment
By Emma and Zach

Equipment:

• Container filled with water
• Molding clay
• Old coins

Question:

What shape of container will hold the most weight?

Prediction:

We have chosen a cube because it is tall and spacious so it will carry lots of coins.

 

Observe:

When we placed our cube gently inside the water, it sank because the sides and bottom were too thick to carry anything.

Method:

Create a boat out of modelling clay.

Fill the container with water.

Place the boat carefully onto the water so it floats.

One at a time , put coins carefully into the boat . Count how many coins are in the boat before it sinks.

Explanation:

I found out that thick things can't float but if you spread out, it will float. Our boat was too thick. so I didn't float.

Money!!!!!!!!

What shape am I going to choose
