| This is the cup of Sodium Polyacrylate with water. |
Today we did a science experiment of Sodium Polyacrylate, Mrs. Hickford said it was a mystery powder at the start. We did it because it was the last day of the term. We got a cup for each pair and the powder was in it. My buddy was Jack R. We had to put warm water with the powder and it turned into a mushy type of substance. If we added more it expanded. The teacher told us not to overflow. Later on, the teacher put salt into our cups. I thought it was going to add more of the substance on, but it actually turned it into water. The teacher told us about what people use Sodium Polyacrylate for and it was for nappies and if you and salt it would turn into the water because it expanded it when you added the salt it would snap it. Also, this really amazed me, that there are 53 million and 290 thousand nappies used by babies!
Did you learn anything in my post today?
Kia ora Theo,
ReplyDeleteWell done on creating such an informative blogpost about your science experiment!
Sodium polyacrylate sounds like a very interesting ingredient, and it is so cool how you were able to experiment with it in your class. I was very curious to hear how it turned into a mushy substance once you added water, and I can tell from looking at the photo you included that the texture of the mixture looks a little bit strange.
Were you allowed to touch the mixture once you added water to it?
If so, what did the mixture feel like?
You mentioned in your blogpost how you had to mix the sodium polyacrylate with warm water for it to cause a reaction.
How much water did you need to add?
Do you think this experiment would still work if cold water was used?
It would be awesome if you could reply to this comment and let me know!
You included some fantastic facts in this blogpost, and I was very surprised to learn how this ingredient is used to absorb the liquid in babies' nappies.
Keep up the fantastic blogging Theo, you’re doing an amazing job!
