RSC Global Experiment 2015 - second investigation

Greetings fellow Scientists!

Today we were trying to find out How quickly can hydrogels absorb water? For this experiment, we used the following equipment:

Firstly, we gathered a capful of hydrogel from the pampers nappies and transferred it into a plastic bottle:

 

 Then, we added water and measured the time taken to absorb it. We recorded our results and, after careful analysis, will post them on the RSC website.

 

 

 

 

 

 

RSC Global Experiment 2015 - first investigation

Greetings fellow Scientists!

Today we have investigated How much water can our hydrogel hold? For the purpose of this experiment, we used the following equipment:

We started by cutting out 10x10cm cloth sample to check its absorption:

Our cloth sample absorbed on average 33 ml of water.

Then, we predicted how much water a hydrogel sample can hold. To check our preditions, we cut out a Pampers nappy into 10x10cm samples and saturated it with water. On average, the hydrogel sample absorbed 325.2 ml of water.
