Happy Easter

Happy Easter. See you on Wednesday 30th March!

Paper Race Update

By the next morning all the paper had started to absorb water.

Paper Race

Today we conducted another experiment to see what would happen when different types of paper were dipped into coloured water.

To make the test fair we kept these things the same:

• container
• amount of water
• colour dye
• size of paper
• amount of paper dipped into the water

The only thing we changed was the type of paper. We used:

• white copy paper
• news print paper
• thin shiny card
• paper hand towel
• crepe paper

We made the following predictions:

• The card will not change.
• The card will change (we could not agree!)
• The paper towel will soak up the most water.
• The white paper will get really soaked.
• The paper will rip if you touch it after it has soaked up the water.

We were right that the paper towel soaked up the most water and the card did not change. Also the crepe paper ripped and we had to put on a new piece!

The paper towel won the paper race as it is the most absorbent. We realised that this is why we use it to dry our hands and mop up spills. If we used the shiny card it would not soak up the water at all.

Weaving

We have been looking at the different uses of paper this term and decided to use coloured paper for our art. We created woven mats and did every step by ourselves.

1. Fist we had to measure the strips for the frame by folding and drawing lines ruler width apart. We cut down the lines from the folded side, taking care not to cut all the way to the end.

2. Next we measured and cut strips from our other coloured piece of paper. 

3. Finally we wove the strips together using an under-over pattern.

What happens to paper if it gets wet?

We decided to conduct a fair test today to answer the question "what happens to paper if it gets wet?"

We took four samples of paper; newspaper, red writing paper, green tissue paper and thick cardboard. To ensure the test was fair we made the pieces the same, or similar size.

Our predictions:

Water will spread everywhere.
Water will go through the paper.
The paper will rip.
The water will make the paper softer.
The paper will go darker.

To ensure the test was fair, we added the same amount of water to each paper and made observations of the results.

We were right about most of our predictions. The cardboard was the only one that was different. We decided this was because thick card was used to package and protect things so needed to stay strong even if it got wet.

Undersea Art

We worked hard on our undersea pictures last week. We added seaweed and coral to the background and stuck on our creatures. Finished pictures to be added soon.
