Chemical Reactions

We did this awesome experiment in science. We had little pieces of paper and we drew a dot on it with a marker then we put it in a cup that had a little bit of water in it. And as the paper soaked up the water it moved up the paper. Because the water had a bigger pull it was then polar and the water pulled the marker up the paper. Near the bottom when the water started is where it is mostly polar. But near the end as the water started to take longer to go up the page it was least polar.

Here are some of the differnt ways I did this experiment.

When w use the water it goes up the paper very fast. So here I just drew three dots and if you can see it brings the colour up the page and also there is some pink in it too.

Here I did a squiggily line of yellow and blue highlighter so it looks like a big blog but it cool.


Then I did the same again but instead I did a stripe.

For me this one was the coolest becasue i drew a flower that was dark red, but the water took the red out so now the bottom is highlighter pink and the red mixed with blue making purple

Now we used alcohol instead, the difference is that the the alcohol pulls the colour up more and it takes much longer for the alcohol to go up the paper.

And I tried these two and they look really cool!
