Wednesday, 3/20/19- A Day- Block Schedule Periods 1, 3, 5, & 7- Happy Spring Equinox & Full Moon!

Lesson Question:

If speed has an effect on the impact of collisions, what happens if an object changes speed? What does this look like on a graph?

Learning Tasks:

1. Do Now– Copy down today’s Home Learning Tasks in your planner. Get out your science notebook and open to page 56. Write your answers to the questions at the bottom of page 56.
2. Simulation Laboratory Investigation– The Moving Man: Position, Velocity, Acceleration PhET– Complete the Moving Man PhET simulation laboratory by using the link to get to the simulation, following the directions and completing the tasks on the view-only handout in the Google Classroom post.

Friday, 3/8/19- A 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 Now– Get out your “The Fast and the Curious” digital lab worksheet. Write your name on your paper and answer the question: How do different factors affect an object’s speed? How does an object’s speed affect its impact?
2. Science Friday– Babies on the Brink

Thursday, 3/7/19- B Day- Block Schedule Periods 2, 4, 6, & 8

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 “Calculating Speed lab worksheet. Write your name on your paper and answer the question: “What did we just do? What did we figure out last time?”
2. Investigation– Review lab questions from Home Learning
3. Navigation Routine– Looking back- What did we just do? What did we figure out last time? Looking forward- What are our next steps? What is a question we need to address? What direction do we need to pursue?
4. Digital Lab– The Fast and The Curious- Use the link posted in Google Classroom to play The Fast and The Curious game. To move the car forward and side-to-side in the game, click and drag the car. Observe what the speed and velocity graphs look like. Click on a point in the speed graph to see the instantaneous speed. After you have finished, DO NOT CLOSE YOUR GAME. Use the speed and velocity graphs and your results to answer the questions on the worksheet.

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.
