Investigation 3.1(Part A): Testing the Motion of Waves Agenda: ❖ Review Questions from yesterday. ❖ Lab 3.1 Modeling body waves with slinkies ❖ EdPuzzle Seismic Slinky HW due Thursday Materials Needed Science Notebook Science Packet-Investigation 3 Chromebook Calculator Stopwatch or timer Slinky Student Sheet 3.1 packet page 10 Science Notebook Today’s Date: Remember, your Science Lesson 3.1: Testing the Notebook is very important. This Motion of Waves is the place you will record your observations. Do Now: Let’s review the questions from yesterday. Don’t forget to put the name of Packet Page 37, #5 the lab and date at the top your notebook. Put your notebook aside. Rubric for Science Notebook  Setting up the Investigation Before you begin: 1. In previous investigations, you used models to study how earthquakes affect buildings. In this investigation, you will use a spring to model earthquake waves. You will model different types of waves and compare how long it takes each type to travel. Procedure: Follow the directions below 2. Packet page 39: Review the materials list at the beginning of the investigation. Discuss the following questions with your group. Record your answers and ideas in your science notebook. Be prepared to share your ideas with the class. A. How can you use the spring to model more than one type of wave? B. How are these types of waves alike and different? C. How can you measure the time it takes for a wave to travel the distance of the spring and back again in your model? D. Which type of wave do you think will move the fastest? Procedure: Follow the directions below 3. As a class, we will use popsicle sticks to decide who will do each part of the lab. ❏ Who will hold the spring? ❏ Who will make the waves? ❏ Who will measure (Mrs. Baldwin) and record the time? Look over Student Sheet 3.1: Simulating the Motion of Earthquake Waves, Procedure: Follow the directions below 5. Sketch the appearance of each kind of wave on your student sheet. Procedure: Follow the directions below 7. For each type of model earthquake wave, calculate the average time for all three trials. Record these values on your student sheet. Procedure: Follow the directions below 6. Use the slinky to model each type of wave for three trials. For each trial, measure the time it takes for the wave to make one complete trip from the wave-maker’s hand, up to the hand of the slinky-holder. Record these data on your student sheet. Answer these questions in your science notebook: a. In this model, what does the spring represent? b. What does the person holding the spring steady represent? C. What does the person moving the spring represent? Why doesn’t the model work if that person shakes the spring more than once? 7. For each type of model earthquake wave, calculate the average time for all three trials.  P waves and S waves are body waves. They occur in the earth’s crust. P waves travel faster than S waves.  Head over to Schoology.
