- Learned about the three states of matter: solid, liquid, and gas, as crayons start as solid wax and melt into liquid when heated
- Explored the concept of melting and its effects on materials
- Understood the process of heat transfer through observation of the wax melting when exposed to heat
- Learned about the role of temperature in changing the state of matter
- Discovered the physical properties of wax, such as its ability to harden and retain shape when cooled
- Understood the difference between reversible changes (melting and solidifying of wax) and irreversible changes (burning of wax)
For continued development related to this activity, encourage the child to:
- Explore the chemical composition of different types of crayons and how it affects their melting point
- Create a graph to show the relationship between temperature and the time it takes for a crayon to melt completely
- Experiment with mixing different colored melted wax to create new colors
- Research the history of crayons and how they have evolved over time
