1 Form and Function: Part 1 –Identifying Structures in the World Mr. Williams – Grade 7 Science

2 What are we going to learn? By the end of this unit, you will be able to understand the following concepts: – All structures have a purpose – The form of a structure is dependent on its function – The interaction between structures and forces is predictable

3 Holding Up Things… Ok, so your desk holds all of your papers and books. Your chair supports and holds you while you are sitting. All of these things are able to do so without tipping over. How are these structures able to do this? Lets find out… You are going to build a support to hold a textbook 30cm above the desk. Your materials include: Building rods ($0.10 each) Masking tape ($0.50 per half meter) Your objective is to build a structure that will support the book with the cheapest material cost! Good luck!!!

4 Structures all around us Most of you think of structures as buildings right? However, structures are much more than this.
