"Science is a way of investigating, understanding and explaining our natural world, physical world and wider universe" (NZ Curriculum).

Students need to lean what science is and how scientists work as well as scientific knowledge.

Science programmes at Eastern Hutt aim to provide hands on investigations that will develop students' curiosity of the world around us and an interest in science.

What paper is the best to wrap a parcel?

The Year 2 students have been learning that different materials are used for different jobs.
For example - We use glass for windows because we can see through it. We use metal for a hammer because it is hard. We use fabric for clothes because it is soft and can bend around our bodies.

We thought about the different types of papers there are and that some would be better for wrapping a parcel than others.
Foil Paper Newspaper Tissue Paper

Each class looked at different types of papers and had to test which would be the best to wrap a parcel to post to a friend.

We decided that the paper had to be strong and waterproof.

To test which paper was the strongest we made a handle out of the paper and loaded the cup with marbles. The paper that held the most marbles was the strongest.

To test which paper was the most waterproof we used a dropper to put water on the paper. The paper that held the most water before it started to drip through was the most waterproof.

In this class the strongest and most waterproof paper was the foil so we decided this would be the best to wrap a parcel.

The students had to be scientists today by observing, testing, measuring, counting and recording their results.
