Welcome Viewers back to my blog,
Today we are going to be talking about an experiment I did with my friends Khiel and Lucas. First, before we started our experiment we had to predict what will happen. Our science teacher Mrs Wheeler said there is no wrong in guessing what will happen.
I wrote that the gummy bear will absorb the saltwater, sugar water and water. After when it absorbs it I'll and grow in size. When we started our experiment we first got some saltwater and put two gummy bears in the saltwater. Then we went and got some sugar water/sugar dissolved in water. Then we got some plain water that has been filtered. We got the gummy bears and put them in. We also got 2 gummy bears that were not in any of the water. We took some pictures of the gummy bears.
We left our gummy bear for about 24 hours and when we checked it people thought it grew in size. But it just looked like it grew. When we got our gummy bears we observed them and noticed that the water one broke it in half. I took off the lid to feel them and they were really sticky. They were also fragile so they break easily when you touch them.
After our experiment, we watched a video of someone doing a gummy bear osmosis experiment. Their one grew in size because they left it out for only about 15 minutes. Our one burst because of the water so it couldn't grow in size.
Hi Aaron
ReplyDeleteI have enjoyed reading your blog. I like your hypothesis, did your experiment results prove you were correct?
Can you think of how we could get more accurate results?
Putting photos into your blog shows everyone what happened.
Well done Aaron I am impressed with your scientific approach.
