Materials Matter

Introduction

Hello Mad Materials Scientists!

We have a very important job for you. As miniature mad scientists in this unit you have learned a little about matter and the scientific method of investigating materials.

Today you will investgate and report back on your experiment of testing different materials on whether they leak, soad or repel.

Task

Leak, Soak or Repel

varable table

we will change: Materials

we will measure/observe: how many drops of water can different materials take before they leak.

we will keep the same: (control method)

The ruber band

The amount of materal

The cup remains sill

The height of the water is droped from

the size of the drops

Task:

We want to find out which different material will leak, soak or repel the water droplets, so we know which materials are used best to clean up thing/soak up. what repel the water so it protects it from getting wet and which material water will leak through.

students will be put into groups with one student taking the roles of manager, speaker and director.

a table will be recored with in sciecne books which will include:

type of material/name
what do you prodict will happen? explain why
tally: under of drops
write about and draw your observation of what is happening
may take phots for evidence with Ipads

Manager will collect the material and bring back to their desk

Process

Materials needed:

x3 rubber bands
x1 food dye dropper
one of each material provided
x 3 plastic cups
science journals

Evaluation

campairing the results

which material soaked up the most water?
which material didnt soak up any water?
which material soaked up a little water?
whitch material repeld the water?
which material obsorber?
were you suprised by the results?

Conclusion

Hooray!

Thankyou mini scientists for experimenting and finding out about which materials leak, soak and reple now i now whatto use these materials for!
