If speed has an effect on the impact of collisions, what happens if an object changes speed?
- Do Now– Get out your Acceleration Lab worksheet. Write your name on your paper and answer the question: What are three ways an object can accelerate?
- Science Friday– The Bouba-Kiki Effect
- Video Segment– Science of NFL Football: Position, Velocity, & Acceleration
- Investigation– Acceleration- Observe what happens with the accelerometer. What pieces of the puzzle did we figure out? Review answers to lab questions.
- Driving Question Summary Table– Complete the DQST on ISN pgs. 50-51 for the Acceleration lab.
How do different factors affect an object’s speed? How does an object’s speed affect its impact?
- Do Now– Copy down your Home Learning task in your planner. Get out your science notebook and open to page 55. Read your definition of a reference point. Write your name on your paper and answer: What reference point would you have to use to be moving right now while you sit in your seat?
- Investigation– Calculating Speed and Determining Velocity- Observe a collision into a barrier on the demonstration track. Finish graphing your data. Answer all of the lab questions, including Reflect and Apply. What pieces of the puzzle did we figure out?

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 Table of Contents- “DQST p.50″ (Left Side), “DQST p.51” (Right Side), “DQST p.52” (Left Side), and “DQST p.53” (Right Side).
- Class Consensus Initial Model– Together, let’s look at samples of models in Google Slides so we can see if our explanations agree and in what areas we disagree. From that discussion, we will build a Class Consensus Initial Model. Tape your model as a flip page to ISN p.48.
- 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.
- Driving Question Summary Table (DQST)– Set up the DQST on ISN pages 50-53 for the driving question: How can we design a crash protection device to absorb enough energy during a car crash to save lives?
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.)
Do liquids follow the same rules for sinking and floating as solids? Do all liquids have the same density as water?
- Do Now– Copy down your homework assignment in your planner. Get out your science notebook to pages 52-53.
- Driving Question Summary Table– Complete the DQST on ISN pgs. 52-53 for the Sinking and Floating Investigations on ISN pgs. 62-65.
- Final Model/Explanation- Watch the phenomenon again carefully. Also check out this person floating in the Dead Sea, these large floating ducks, and floating lemons but sinking limes. What determines whether something sinks or floats? On the white paper, draw your ideas of what you have learned is happening when something sinks or floats.
