This simple game allows you to draw an iceberg and see how it floats. You will notice that most of the iceberg is below water, about 90%! 

Iceberger was made by Joshua Tauberer, a software engineer that made this digital resource as a hobby. It went viral in 2021 because it is really an incredible tool to learn more about icebergs! Link webpage. 

A more complex version where you can also analyse melting and forces is available at this link.

What floats?

Materials:

Method:

Objective:

Put water into an empty yogurt cup and leave it in the freezer overnight. What happens to water when the temperature goes below 0°C? It freezes. Pop out the ice and place it in a container of water. What happens? Draw a picture of your iceberg. 

Did you notice that only a small part is above water? About 10%.

Do you think all materials will behave in the same way? Find different objects that are similar in shape to your block of ice, maybe a piece of wood, glass, plastic, a rock. Create a table and write down your observations. Note which one floats, which one sinks and any other unique characteristic.

Video by Jessica Alessi, a Marine Scientist who is specialized in marine mammals and does amazing research on her boat in Sicily where she often sees whales and dolphins, in fact the photos in the video are also taken by her! 

This interactive webpage takes you from the warm surface waters, known as the Euphotic zone or Epipelagic zone, down to the cold depths in the Aphotic zone, webpage link. Look at the various sensors, find depth, temperature, pressure and light and see how they change as you scroll down. Click on the icons and do "discoveries" and then take the quizzes and see how much you learned!
