What happens when objects collide?
- Do Now– Copy down your Home Learning assignment in your planner. Get out your science notebook and add to the NEW Table of Contents- “Crash Test Model, Questions p.48 (Left Side). Head page 48 properly with “Crash Test-Initial Model, Related Phenomena, Questions-2/19/19.”
- Attempt to Make Sense/Initial Explanation/Model– Let’s attempt to make sense of what we noticed when objects collide. How can you explain what you saw? On a piece of blank copy paper, draw a diagrammatic model of what you think is happening when objects collide. It’s not just a drawing of objects colliding; it needs to explain what happens when objects collide. Label the parts of the model and use words to explain what’s happening. In groups of 2 or 3, compare your models. Use the “Communicating in Scientific Ways” sentence starters on ISN p.14 to share your ideas & ask questions about other models. Focus on the “Observe” (#2) and “Ask Why and How?” (#1) questions.
- Identify Related Phenomena/Write-Pair-Share– Where else does this happen? Think of other times when you experienced collisions. WRITE a brief description of times you can think of when you observed crashing objects on ISN p.48. Try to come up with ones that make you wonder why/how it happened. PAIR with your table partner to share your related phenomena and be prepared to SHARE an example or two with the class for the Class Record of Related Phenomena.
- Develop Questions/Driving Question Board– What do we need to figure out to explain all of this? Brainstorm “What We Wonder” questions about colliding objects and make a list of those questions on ISN p.48. For each of your observations on ISN p.49, think about a question that you can investigate to help you better understand it. Choose the most compelling or interesting question from ISN p.48 and write it big and bold on a notecard using a marker. Write your initials and period number in pencil on the front corner of the card. Bring your card to the scientists’ circle. Read your question and post it on the Driving Question Board (DQB). Explain how it is related to another question on the board.
Ideas for Investigation/Next Steps– Which of the questions from ISN p.48 or from the Driving Question Board (DQB) would you like to investigate further? What would you like to do to investigate any of those questions? (See Question in Classwork in Google Classroom under Today topic.)
