Material Properties and Purposes
What you will learn from this videoWhat you will learn
- Some materials have properties best suited for certain purposes.
- In this lesson we will learn about stretchiness, absorbency and strength.
- Comparing different materials involves doing experiments.
-
Discussion Questions
- Before VideoWhat kinds of materials have the property of being stretchy?ANSWER
Rubber bands, bungee cords and balloons are all stretchy.
Paper towels, sponges, diapers and towels can all absorb liquid.
Metal, wood and bricks are examples of strong materials.
Since a bridge needs to hold up a lot of weight, it is best to choose a strong material such as metal or concrete.
It’s not strong enough. It’s not water or weather proof.
Test each material to see which one makes the object go the farthest.
- After VideoWhy is pizza not a good choice for building a chair?ANSWER
It’s not strong enough to hold a person up. It will just collapse when you sit on it.
You could test each material by seeing which one absorbed the most liquid.
The sign is brightly colored so that people see it.
If it wasn’t stretchy you wouldn’t bounce back up. It also allows you to slow down safely.
A raincoat, umbrella and a house should not be absorbent.
They need to choose the right materials based on the purpose of what they build.

This helps it hold up lots of heavy cars and trucks. Other materials that are strong include wood and concrete. Many buildings are made of these strong materials.

This helps it to serve its purpose so that the jumper can slow down safely after they jump. It is also important for a sock to be stretchy so when you put it on it does not rip.
