What happens when you heat up slime? Learn all about the properties of materials with this on-trend science spectacular…
Kids love slime in weird and wonderful ways, with YouTube superstars driving the phenomenon to giddy new heights. This is one science lesson your students will go gooey at the knees for.
These activities could be taught in one session or individually as stand-alone activities investigating materials and their properties.
Starter activity
To begin, ask your students who has made slime before. Discuss why they made it and what makes it so special and fun to play with.
Next, ask your students to discuss in pairs what slime could be used for besides fun at home and school. Share ideas with the class.
Explain that today they will be working together to make two different types of slime and comparing them in lots of different ways. Now that sounds slime-tastic!
What they’ll learn
- Compare materials on the basis of their properties
- Observe that materials change state when they are heated or cooled
- Set up simple practical tests
- Make systematic and careful observations
- Gather and record data
