Finding Friction

 This week we built some bridges and experimented with friction. 

On Monday, Grade 2 explored the forces interacting on bridges as they tried to build a strong, sturdy bridge that could withstand the most weight. 

On Tuesday, we had a double period of PE to make up for a cancelled PE lesson on Monday as it was too wet and rainy. The students started building up their stamina by running the length of the green field and back in preparation for Sports Day in the spring. We also played some team flag tag. Then on Wednesday, we continued our PE unit on rolling, sliding and gliding as we used the roller boards for some team races. 

In unit, we experimented with different materials to discover which had the least and most amount of friction. We also learnt about making it a fair test by seeing to it that each material was about the same size and weight. Each group did four trials, recorded their results and then came to a conclusion based on their results. We even combined all of their results in a tally chart as we have begun a new unit on data management in math and our combined results showed that plastic had the least amount of friction and that sandpaper had the most as they were the first and last to slide. 

On Friday, we started working on our next project, how to protect an egg from breaking when dropped! In groups of three the students discussed and began designing their plans to build something to protect an egg. On Monday, we will start building them. 

Monday, will also be Carnival so please have your child wear or bring a costume to change into. The costume can be anything as there is no theme.
