Big Ideas of this unit:

• A structure has both form and function
• Structures are affected by forces acting on them
• Structures need to be strong and stable to be useful

Questions we will be investigating this unit:

• What is a structure?
• What are the similarities between man-made and natural structures?
• How are strong and stable structures built?
• How do forces (e.g., pushing, pulling) effect structures?
• How can we strengthen materials when building strucutures?
• How do structures impact our environment?
