Newton's First Law - Tier 1 Activities.

Complete each of the activities below, in order, please. After completion of the following activities, you will have a better understanding of the term INERTIA, why a pencil just stays where it does and why a satellite continues around the Earth without falling from its position.

__ ** Part 1 : Pennies and Newton’s First Law ** __ Materials Needed: Bottle or beaker, Note card and Penny. Instructions: 1. Each student will place the note card over the mouth of their bottle/beaker so the note card is centered on the bottle. 2. Then place the penny on the note card directly over the bottle/beaker opening. 3. Try to flick the note card out from under the penny so the penny lands in the bottle/beaker - repeat as necessary. 4. Answer the questions on the note sheet provided.

__ ** Part 2: Newton’s First Law Flash ** __ // 1) View the following web page. // // 2) After viewing the Flash animations, discuss the questions from the web page within your groups and write a __6-word essay__ as a group on the note sheet provided (summarize Newton's 1st law of motion in 6 words). //
 * Newton's First Law Flash

__**Part 3: Video and Grafitti Conversation**__ // You will be making a Graffiti Conversation after viewing the video. //
 * 1) Write words or draw images (or a combination of the two) on the paper to spark conversations with your group members showing what you learned about INERTIA from the video.
 * 2) Pause the video as needed.
 * 3) Make sure your "graffiti poster" demonstrates what you learned and discussed about INERTIA.

__ ** Part 4:Sir Isaac and Seat Belts ** __ // Read the following article about seat belts. Take turns reading the article aloud while all group members follow along. Complete the following Notes Page. Notice the question at the top of Part 4. As you read the article, **__keep this question in mind__**. The notes column is for factual information that relates to the question. The thinking column is for your reactions, connections, questions, and inferences. On the bottom right in the thinking column, you must complete the question asked with evidence. //

__ ** Part 5: Newton's 1st Law Simulations & Answering Questions ** __ Click on each of the links to use the simulations. The first simulation has __ **4 stages** __. ** Make sure you play __each stage__ and answer the question on the notes sheet **. Space Truck Rescue Simulation Space Truck Mining Simulation

In this experiment you will try to drop a tennis ball on a target as you run past the target. Think it’s easy? Before you begin, try to guess what will happen. Try to figure out when you will need to release the ball in order to hit the target. Write down your predictions in your study sheet. Give the reasons why you think you are correct. As you conduct this experiment, think of the challenges Air Force pilots had before the invention of the guided missiles that are used today. Pilots in World War II had to understand mathematics in order to drop bombs on targets while causing as little harm as possible to surrounding buildings and people. These are the same concepts that you will learn with this experiment.

Materials

You will need the following items for this experiment:

• one tennis ball • clearly-marked target(s), i.e., notebook paper, a chalk mark, or tape || 1. Place a target about 10-15 meters away from a starting line. |||||||| || 3. Have three students stand alongside (but slightly back from) the running path to act as observers. One should stand before the target, one at the target, and one just after the target. Their objective is to determine exactly where the runner released the ball and where the ball strikes the ground. 4. Ask the runner to sprint toward the target as fast as she or he can and try to drop the ball so that it lands on the target. 5. Next, have the observers make a diagram in their study sheet of where the ball was released and where it landed. Repeat the experiment until the ball hits the target. 6. Use the information in Step 5 to predict what would happen if a student ran at a slower speed (not walking). Repeat Steps 4-5, using a different runner sprinting at a slower speed. 7. Use the information in the previous trials to predict what would happen at a walking speed. For the last trial, ask a student to walk toward the target. Repeat Steps 4-5. 8. Write a summary of your results in your study sheet. Form conclusions based on the speed of each runner, the location of each ball release, and the exact point where each ball landed. ||
 * Procedure
 * 2. Hold the tennis ball and do not let your elbow leave your side as you run and drop the ball. Do not throw the ball. You should hold the ball from its sides so that you can release your grip as you let it drop. Remember to drop the ball and not throw it, otherwise you will change the intent of the experiment.
