Making a water filter with Sally the Watercare lady

Watercare

On Wednesday Room 16 were lucky because the  Watercare lady Sally came in to talk to us about the water cycle.

First Sally said to us, “Who knows how the water cycle works?”  Room 16 knew a lot about the water cycle because we learnt about it last year. We learnt about it last term as well.

After that she said we are going on an adventure. We were pretending to be water drops. This is how it went. We were in a lake. Soon the sun came out and we evaporated. After that we were falling as rain. Then we did it all over again.

After Room 16 did the adventure, Sally talked about how she cleaned up the water because she works for Watercare. It was like the water cycle but when it rains some of the water goes into the dams.

The thing that they use has heaps of strings that catches the dirt that goes through little pipes from the dams. Then the water goes into big tanks. At the beginning the pipes are massive then they get smaller and smaller until the pipes are only about 5 centimeters wide. When the pipes are only 5 centimeters wide the water flows really fast and that is how they clean the water up. If they didn't clean the water we wouldn't be able to drink the water without getting sick.

After that we did an experiment to see who can make the cleanest water. I buddied up with Tyrone. We used dirty water, toilet paper, cotton balls, bark and sand. The team that made the cleanest water won a chocolate fish. Tyrone and I used toilet paper. Tyrone and I was beginning to have clean water. When the water came out Tyrone and I was excited because we had clean water. It was a little bit dirty but when Sally judged it we came third. We only got one chocolate fish instead of two. Liam, Kenneth and Ashton came first.

I enjoyed learning about the water cycle. I wish I can do it again. 

A visit from Sally the Watercare lady

On a sunny Wednesday Sally who works for the Water-care came into Room 16. She told us some facts about the water cycle.

Next she told us a story. We were a water drop. We were pretending to be the sea and a big boat came over. Then it dropped all it’s oil into the sea. After that we were swimming away from the oil. Next Sally said, “We are going to make water filters.”

So we went outside and got into a silent line. Then we walked over to the stuff she had. She had bark, cotton balls and paper towels. Suddenly Sally gave us all some little containers. One had a hole in it and the other container didn't have a hole in it. Then we rushed to get our equipment. First me and my buddy Zayden got some sand. When we tried it it didn’t work. So we tried some bark but that didn’t work either. Next we tried cotton balls. When we tried the cotton balls it kind of worked. After that we tried the paper towels. Then we asked Sally for our final one. We got the paper towels then we tipped in the yucky water and we were done. Then Sally said, “Put one of your filters on a letter."

Last of all Sally took us to the junior playground. We were going down the slide. Sally put down a big blue mat on the ground. Then our whole class was on the mat.

Last of all Room 16 went back into Room 16's class. Sally put a brown pipe in front of the desks. We were in line to go under the pipe and the whole class was under the desks and some people were laughing. It was cool. When we were under those desks, me and my buddy were in the back. It was like a cozy, coughy blanket.

I think we did good on our filters and the water cycle.

Static Electricity Experiment

Question: What will happen when you rub a balloon on your hair?

Hypothesis: Hair will stand up after you rub a balloon on your hair.

Equipment: Hair, balloon

Method: First you blow up a balloon. Next you tie up the balloon. After that you rub the balloon on your hair for about ten seconds. Soon you take the balloon and hold it up to your hair then your hair will be attracted to the balloon.

Results The hair stood up when the balloon was near the hair.

Conclusion When you rub the balloon on your hair some of the positive particles in your hair move to the the balloon. Then the negative particles wants to meet the positive so the hair will stand up when the balloon is near the hair.

Static Electricity Experiment

We had fun today learning about static electricity.

Question: What happens when you rub a balloon on your hair?

Hypothesis: Hair will stand up after you rub it with a balloon.

Equipment: You will need a balloon and your hair.

Method: First we blew a balloon up. Next we rubbed it on someone’s hair. We rubbed it for 10 or more seconds.

Results: The hair stood up and to the balloon.

Conclusion: When we rubbed the balloon on someone’s hair the positive particles rubbed off our hair onto the balloon. The negative particles in  the hair wanted to be together with the positive particles in the balloon.

Static Electricity Experiment

Question: What happens when a balloon is rubbed against hair?

Hypothesis:Hair will stand up after we rub it with a balloon.

Equipment: Balloon, hair.

Method: First we blew a balloon up. Next we rubbed the balloon on somebody’s hair. We rubbed it for 10 seconds or more.

Results:The hair easily stood up so it is true that when you rub a balloon on your hair your hair floats.

Conclusion: When you rub a balloon on somebody’s hair the hair stands up.

The reason is-  because there is more positive than negative particles in the balloon. Positive and negative particles love each other so that is why your hair had floated up.
