Guiding Questions:

Why does ice melt faster on metal than wood?

Why do water droplets appear on cold drinks?

 

Today in lab, we explored what melting is, and described it as a phase change from solid to liquid. We also revisited our tests with the sink plunger and drew a particle model. We described that when we see the plunger get pushed down air particles escape and leave fewer particles in the plunger creating a vacuum.

To explore why ice melts faster on metal compared to wood we completed simulation activities. We found that metal is a conductor and wood is an insulator. Metal being a conductor allows energy to pass through it faster, hence why the ice melts faster on metal. We then completed another simulation activity where we explored why when you place a cold drink in a warm place, water droplets appear on the outside of the glass/can. We found out the explanation is condensation, the cold water evaporates into the warm air, and when the air around the glass becomes too dense from the water, it'll drop leaving water on the outside of the cold drink. 

After completing both simulations we made flip videos to explain what we found.
