This week in science we continued our work with materials. We were set another task by Professor Pole! He wanted us to choose the most suitable material he could use for his umbrella. He told us it must be waterproof and not absorbent. 
 
We discussed the idea of a fair test – a test where’s only one variable is changed while all the other variables are kept the same. We established the thing that would change in our experiments would be our materials.
 
We tested fabric (felt), tissue paper, paper towels, cardboard and a plastic bag. We made our predictions first just by feeling the materials that might be the most suitable for an umbrella. 
 
We worked in our table groups and tested all the materials using water. At the end of the experiment we came back together to discuss what we found out. We found out that the best material Professor Pole could use would be the plastic bag because it is waterproof and all the other materials were absorbent… pointless for an umbrella! 

 

Materials

This week the Toucans have been learning about different types of materials. They have been identifying and comparing  glass, plastic, metal, brick, rock, paper and cardboard. To start with, they were given a range of different everyday objects to explore as a table group. They were encouraged to discuss the uses of the different objects and to see if they could sort them into different groups. Each group then shared their findings with the rest of the class. 

Toucans were then encouraged to re-sort the materials to see how many different groups they could make.  Miss Hookes asked the children why certain objects were made with certain materials, for example why wouldn’t table legs be made of cardboard? Why are our classroom chairs made of plastic and metal? Why are windows made of glass? The children were then asked to share their thoughts. Toucans then went around the classroom to spot different objects made with each of the various materials and recorded these independently.

Miss Hookes also introduced the Rocket Words: flexible, rigid, smooth and rough.
