We haven’t done very many experiments lately, at least not any that I actually planned! Cutie Pie seemed to want a little one on one time and asked if we could do an experiment the other day. I pulled out 365 Science Experiments book (published by Hinkler Books) and flipped open to this conduction experiment number 128. It couldn’t have been more perfect as it was right before our hot cocoa date! Read on to see why!
- Hot water
- Drinking glass
- Ceramic mug
- Foam cup
“Find out which material is a better conductor of heat.”
- Fill each “cup” with the hot water.
- Feel the outside of each container with your hand. Be careful, the water was hot!
- What do your fingers tell you (sense of touch)? Which was hottest? Coldest? (Or which couldn’t you touch for long?)
- The ceramic mug felt hottest.
- The glass at first wasn’t very hot, but when testing the temperature of each container again, we noticed it had gotten quite hot. Possibly a slow, but good conductor of heat?
- The sound of pouring water was different with each container we used. Cutie Pie hypothesized this was due to the different shape of the containers or the materials the containers were made of.
We put this all to the test during our hot cocoa time. Cutie Pie thankfully doesn’t drink his hot cocoa at a very hot temperature, so I allowed him to pour it into the different containers to see the real-life application, since before it was just hot water, and “hot water isn’t really something you drink” according to Cutie Pie!
