This term we are learning about science and the topic is ‘Material Matters’

Last week we participated in a school visit from hands on science we did lots of experiments including an absorbency test, a flammability test, a strength test and making a latex disc.

My favourite experiment was the abaorbancy experiment which was testing which materials absorbed water the fastest. Dri-fit which is a Nike made material was the quickest to absorb the water.

Here is the science report for what we did:

Aim:

To see which material absorbs the water the fastest.

Hypothesis:

I hypothesise that the dri-fit material will absorb the water the fastest because dri-fit absorbs sweat quickly.

Variables:

Measure: how long it takes for materials to absorb the water.

Change: the materials

Same: the speed of your counting, the amount of water and the size of the material.

Materials:

•water

•materials (dri-fit, cotton, nylon wool, plastic, nomex)

•a timer

Method:

1. Choose a material and drop a tiny bit of water on it. When the water drops on the material start the timer.
2. When the material absorbs the water stop the timer and repeat for the next material.

WHAT HAPPENS WHEN THE MATERIAL DOESN’T ABSORB THE WATER

If the material doesn’t absorb the water stop the timer after 1 minute to 3 minutes and record the time on the timer with a ‘+’ after it.

(For example: 3min+)

What experiment in this post would you like to do your self?
