You all have some understanding of friction and in particular can say that it occurs when 2 surfaces rub together. For this investigation you will observe a wooden block being pulled across different surfaces while observing and recording how much force was needed to do this. When you have completed this infestigation you will use your findings and some further research to construct more detailed knowledge about the force of friction. 
 To help you to understand Newton's Laws you today made a good copy of the work you did yesterday. Take a look at Heather's example below. For each of the three laws Heather used her understanding of baseball to explain the law in her own words. This work is due at the end of class. You may complete this for homework and turn it in on tuesday. Click here for a video to give you some ideas.  Heather explains Newton's 3 laws through her understanding of baseball. 
We had a fun time today connecting Newton's three laws of motion to our favorite activity! For me his first law was illustrated when i double ejected out my skis one time. my skies stopped but i continued in motion until the force of the ground stopped me.. not fun!!!!!!
Today we completed a lab that has a multitude of ways to look at force as an interaction. Everyone found it hard to talk about force as it is definately intangible but at the same time something we all have a familiarity with. We were connecting the Winterfest trip to our understanding of motion to help with using the spring scales! At the end of class I was hopeing you would all realise that it is an unbalanced force that set an object into motion but I think we need to talk some more about this!
We all know what happens when we push or pull on an object but we are delving into why this happens! We practiced using a spring scale to measure how much force is needed to move different objects around the room
