Thursday, 2/28/19- A Day- Block Schedule Periods 2, 4, 6, & 8

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.

Investigation- Calculating Speed & Determining Velocity

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

Here are some of the ramps that we set up to measure the time that it took marbles of different masses to move down a ramp of a particular distance.

Monday, 2/25/19- B Day

Lesson Question:

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

Learning Tasks:

  1. Do NowCopy down your Home Learning assignment in your planner. Get out your science notebook and add to the Table of Contents- “Calculating Speed p.55 (Right Side). Head page 55 properly with “Calculating Speed-Investigation-2/25/19.”
  2. Scientists’ Circle– Looking back- What did we just do? Looking forward- What are our next steps?
  3. Video/Scientific Language Key WordCheck for Understanding-Watch “Expedition 2: A Universe of Motion” to meet Matt Brumbelow, a research engineer. Record the lesson question on ISNp.55. Set up ISN p.55 to record the definitions of the following scientific language keywords: reference point, displacement, distance, speed, velocity. Record the same terms and page numbers in the Index in the back of your ISN. Also, set up ISN p.55 to answer the “Check for Understanding” questions on the reading assignments.
  4. Crash Protection Device Design Challenge– Your goal is to design a crash protection device that will absorb enough energy during a car crash to save lives. What materials do you want to use? Why will those work? Are there design features you want to include? Use ISN p.54 to draw an initial design model and ask questions you could investigate to find answers that will help your design. You do not need to agree on a design right now.
