Can heat change matter?

"If we apply heat to ice and chocolate which are currently solids, what will happen?"

This was the question that we set out to answer through our experiments on Wednesday.

We first experimented to see what would happen to a piece of ice when placed in a glass of hot water and an empty glass.

We learned that the ice cube placed in the glass of hot water melted and turned into a liquid much faster than the ice cube placed in the empty jar.

Next, I asked, "What do you think will happen to this piece of chocolate if we apply heat from a hair dryer?"

We learned that once again, heat changed our solid piece of chocolate to a melted liquid.

Lastly, we experimented with the heat from our hands to see if we could melt an ice cube!

What is a liquid?

Last week, we explored with solids by trying to place them in different shaped containers. We learned that solids always hold their shape. 

Today, we did the same thing with liquids. We started by reading the leveled text, Melting Snow.  

Next, we observed the three different containers that I had poured water into. I posed the question, "Which container do you think is holding the most water?"

After observing, the students recorded their prediction of which container they thought was holding the most water in their wonder journals.

They were amazed to find out that there was the SAME amount of water in all 3 containers! Each container was holding 1/2 cup of water. As a class, we discussed how the liquid took the shape of whatever cup it is poured into!

After that, we decided to have our own liquid race!  We raced a Capri sun, dish detergent, and honey. Before racing, the students wrote their prediction in their journal.

After predicting, it was time for the race! Most of us predicted that the juice would flow fastest!

Of course, the juice flowed the fastest and to our surprise, the honey came in second place!
