Lesson Question:

How do different factors affect an object’s speed? How does an object’s speed affect its impact?

Learning Tasks:

  1. Do Now– Get out your science notebook and open to page 55. Write your name on the piece of paper and compare and contrast speed and velocity.
  2. Science FridayIsn’t This Octopus Adorabilis?
  3. Investigation– Calculating Speed and Determining Velocity- How do different factors affect an object’s speed? How does an object’s speed affect its impact? Determine the average time for each ball from the three trials. Determine the average speed of each ball using the formula: speed = distance/time. Graph your data. Answer all of the lab questions, including Reflect and Apply.

Remember: As long as you act like a scientist when we do science, you will be treated as a scientist and conduct investigations. If not, you get to watch the rest of us do science.

Lesson Question:

How do different factors affect an object’s speed? How does an object’s speed affect its impact?

Learning Tasks:

  1. Do Now– Copy down your Home Learning assignment in your planner. Get out your science notebook and open to page 55. Write your name on the piece of paper and compare and contrast distance and displacement.
  2. Investigation– Calculating Speed and Determining Velocity- How do different factors affect an object’s speed? How does an object’s speed affect its impact? Review Science Safety Regulations and complete Lab Safety Checklist- Before You Begin. Also, review Group Member Responsibilities.
    1. Lab Prep– Attach 2-4 pieces of foam pipe insulation together, using toothpicks to make one long piece. Measure and record the total length of the piece. Use the foam to set up a track for balls to race down. Use materials such as books or cups to create hills in the track. Place a sturdy barrier at the end of the track for the balls to crash into. Test the track with each of the balls to make sure they will make it to the end. Adjust the track as needed. Use a scale or balance to measure the mass of each ball. Record the mass and a description of each ball, including texture and type of material. Stretch a piece of string from the start of the track directly to the barrier at end of the track. Measure the length of the string to determine the magnitude of the displacement from the beginning of the track to the barrier.
    2. Make Observations– Release each ball one at a time down the track. Using the stopwatch, time how long it takes for each ball to reach the end of the track. Repeat this process two more times for each ball. Determine the average time for each ball from the three trials. Make observations about each ball’s motion after it strikes the barrier at the end of the track. Does it just stop? Does it bounce back? If the balls bounce back, do they all bounce back the same distance and speed? Determine the average speed of each ball using the formula: speed = distance/time. Graph your data. Put time on the x-axis and distance on the y-axis. Plot the average speed of each ball as a point. Then draw a line from each point to (0,0) in the bottom left corner of the graph.

JASON Project Operation Terminal Velocity- Expedition 2: A Universe of Motion- Stage 1- On the Move

Articles

  • Talking About Motion– This article describes how all motion is relative to a reference point. The article also covers the difference between distance and displacement and the use of vector arrows to describe movement.
  • Rates of Change– This article defines rate as the amount of change in any measurement over time and gives several examples.
  • Speed- A Scalar Quantity– This article discusses three different ways to examine speed–instantaneous, constant, and average speed. The article also describes why speed is a scalar quantity and how to calculate and graph speed.
  • Velocity- A Vector Quantity– This article defines velocity as a vector quantity representing both speed and direction and distinguishes it from speed. The article also describes how to calculate and graph velocity.

*Links to the above articles as well as guiding questions to accompany them are found in Google Classroom.
