Lesson Question:

What happens when objects collide? How can we design a crash protection device to absorb enough energy during a car crash to save lives?

1. Do Now– Get out your science notebook and open to p.61. Look over your observations of the two collisions in the T-chart. Turn to your partner and discuss what could be causing the differences that you observed between the two crashes.
2. Field Assignment- Performing Crash Tests- Create two line graphs on graph paper from the velocity vs time data for the two car crashes in the videos. Label the x-axis as “time” and the y-axis as “velocity.” Use the graphs to describe what each car is doing during the particular time intervals and record on your graph paper. On the handout, calculate the acceleration for each car during those time intervals. Using the graph, determine the time of impact for each car. Calculate the momentum of each car at the moment of impact assuming both cars have a mass of 1,500 kg.
3. Putting Pieces Together– Take stock- Identify and consolidate ideas you have figured out across your investigations about motion. Put pieces together- Come to a consensus on how the pieces explain what happens when objects collide. Develop a public representation of how the pieces fit together.

Lesson Question:

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

2. 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?
3. Driving Question Summary Table– Complete the DQST on ISN pgs. 50-51 for the Calculating Speed and Determining Velocity lab.

Question:

How do the vibrations of the different sounds compare for higher vs lower pitch notes?

1. Do Now- Read This Brainteaser … bet you CAN!The phaonmneel pweor of the hmuan mnid: I cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdgnieg. Aoccdrnig to a rscheearcr at Cmagbride Uinervtisy, it deosn’t mttaer in waht oredr the ltteers of a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Amzanig huh?
2. Snowball Discussion/Student Graph Analysis– Each problem was worked out on your own. On a long paper, do out the problem that you’ve been assigned. (Seat 1- problem 1, seat 2- problem 2, seat 3- problem 3, seat 4- problem 4) Now pair together and share your ideas/show your problem. (seat 1 and seat 2; seat 3 and seat 4). Finally, share your ideas/show your problems with the cooperative table group. (seats 1 & 2 with seats 3 & 4)

Core Ideas:

• Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.
• Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.

Learning Activities:

1.  Do Now– Get out your science notebook and open to pages 56-57. Take out your data table and your graph paper. Work out the following density word problem on the colored paper strip: “Calculate the density of a cube using the following information: Each side is 2 cm long. The mass of the cube is 16g.

3. Investigation– What is the relationship between mass and density for objects of equal volume? Complete the graph of your data on graph paper. Use the density of each cube to identify the substance that the cube is made from.

Learning Activities:

1.  Do Now– Get out your science notebook and add to the Table of Contents-“Effect of Mass- p.56” (Left Side). Head page 56 properly with Effect of Mass-Model & Conclusion-2/1/17. Answer After Lab is Completed questions 1-5 on Lab Safety Checklist.
2. Investigation– What is the relationship between mass and density for objects of equal volume? Set up model and conclusion page 56. Review data as a class. Graph data on graph paper. Model relative size and arrangement of atoms/molecules in metal, plastic, & wooden cubes. Write conclusion. Trim and tape data table as flip page to p.57 and tape graph paper as flip page to p.56.
