Kesler Science Station Lab Newton s 1 st Law If you have never used my Mad Science Station Labs before please download the FREE Start-Up pack from my TPT store. It will provide you with all of the signage and best practices in order to run the station labs in your classroom. The large directions cards included in this file are intended to be read by the leader of the group once the students get to the station. The smaller task cards can be read by another group member. I prefer that each student do their own lab write-up (included at the end of this file), so that they may use it for reference at a later date. The answer key is provided at the end of the document. Lastly, if any of the internet resources no longer work for some reason please let me know via email at chris@keslerscience.com. I cannot guarantee that all resources will be available, but I tried to choose ones that have been around for many years.
Kesler Science Station Lab Newton s 1 st Law Teacher Directions Explore It! I will spend much of my time at this station making sure that the students are working with the models correctly. You will need a few pennies, a milk bottle (cup would work) and a ring made out of cardboard or durable paper. This model works much better if the ring is pulled out from the inside of the hoop. Organize It! The cards for this activity are attached near the end of this file. Print several sets and then just put them in the basket for kids to pull from. This activity covers all 3 laws. Be sure the students know them all before using this station. Students should be encouraged to do the Research, Explore, and Watch It stations before attempting this one. Illustrate It! You will need to set out map colors and markers at this station. Read It! Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces Watch It! The video is on the free website StudyJams (LOVE this site).

Read It! Station Directions Each member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section. It is important to remember that the answers will come directly from the reading passage.
The Law of Inertia According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain its state of motion. This is often called the law of inertia. The law of inertia is most commonly experienced when riding in cars and trucks. In fact, the tendency of moving objects to continue in motion is a common cause of a variety of transportation injuries - of both small and large magnitudes. Consider for instance the unfortunate collision of a car with a wall. Upon contact with the wall, an unbalanced force acts upon the car to abruptly decelerate it to rest. Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Being strapped tightly to the car, the passengers share the same state of motion as the car. As the car accelerates, the passengers accelerate with it; as the car decelerates, the passengers decelerate with it; and as the car maintains a constant speed, the passengers maintain a constant speed as well. What would happen if the passengers were not wearing the seat belt? What motion would the passengers undergo if they failed to use their seat belts and the car were brought to a sudden and abrupt halt by a collision with a wall? Were this scenario to occur, the passengers would no longer share the same state of motion as the car. The use of the seat belt assures that the forces necessary for accelerated and decelerated motion exist. Yet, if the seat belt is not used, the passengers are more likely to maintain its state of motion.
In the first paragraph the word resist means? What would be another good title for this passage? A. prevent B. allow C. accept D. surrender A. The Story of Isaac Newton B. Newton s 3 Laws C. How Seatbelts Work D. An Explanation of Newton s 1 st Law of Motion and Inertia The author suggests inertia is most often experienced? A. when planets orbit B. in moving and stopping vehicles C. at amusement parks D. when watching rockets launch According to the article, what is one benefit of a seatbelt? A. It keeps you from falling out of the car. B. It affects the inertia of the passenger C. It allows you share the same motion as the vehicle D. They make you fly out of the car when stopping.

It will stop eventually B. It will continue to move until it is acted on by an unbalanced force. C. It will speed up over time D. It will slow down over time An object at rest will remain at, and an object in motion will remain in unless acted on by an external force.

Organize It! Station Directions It is recommended that you have completed at least two of the following stations before working at this station. -Read It! -Explore It! -Watch It! -Research It! Every student will answer the questions from the task cards on the lab sheet in the Organize It! Section. Please mix up the cards again before the next group arrives at this station.
1. Read and organize the situation cards to fit into each of the three categories. 2. Have the teacher check if you are correct. Newton s 1 st Law The Law of Inertia Newton s 2 nd Law The Law of Acceleration Newton s 3 rd Law The Law of Action/Reaction
A train stops suddenly at the train station and everyone in the cars continue moving forward. A teacher sitting in her rolling chair pushes against the wall and moves in the opposite direction. A model rocket flies upwards as the engine combusts and creates a force towards the Earth. A rollercoaster takes off quickly and everyone s head is thrown backwards towards the headrest. If a bowling ball and a basketball are rolled with the same amount of force, the basketball will accelerate faster. A shotgun is fired and the kick of the gun injures a person s shoulder. A semi-truck and a small car are traveling at the same speed. They each hit the brakes at the same time, but the truck takes much longer to slow down. A magician quickly pulls a tablecloth out from under a set of dishes. The dishes remain in the same spot.

Law of Inertia Answer Key Explore It! Task Card #3: 1. The penny falls into the jor because of the law of inertia. The object is at rest and wants to remain at rest. There is no force great enough to act on it 2. Newton s First Law Task Card #5: 1. You can catch the penny because of Newton s 1 st law. The penny wants to remain at rest but then the force of gravity acts upon it. 2. Newton s 1 st Law Write It! Watch It! Task Card #2: An object s resistance to change in motion. Task Card #3: It will continue to move until it is acted on by an unbalanced force. Task Card #4: An object at rest will stay at rest, and an object in motion will stay in motion unless acted on by an external force.

Law of Inertia Answer Key Write It! Task Card #1: Newton s first law states that an object in motion stays in motion, and an object at rest stays at rest unless acted on by an external (unbalanced) force. Task Card #2: As the train slows down in the station th epassengers will want to continue to move forward because they have their own inertia. Everyone in the train would be leaning forward. Task Card #3: The planets are all in motion and would continue in the same speed and direction if it wasn t for the force of gravity from the Sun. Gravity and inertia work together to allow the planets to orbit.
