What is #ScienceSaves? What is #ScienceSaves? #ScienceSaves is a campaign to promote the fact that thanks to science, individual lives are longer, healthier, easier, and fuller. We hope this lesson helps your students understand how #ScienceSaves!
Mr. Nils Bohlin Engineer and Inventor Saving Lives with Seat Belts Image: https://www.1069thex.com/2018/10/06/seat-belts-are-the-first-line-of-defence/
Meet Nils Bohlin He invented the 3-point seat belt Seat Belts Save Lives Everyday Image: https://scienceheroes.com/index.php?option=com_content&view=article&id=147&Itemid=146
Nils Bohlin was an engineer. What is an engineer? An engineer is a person who uses science to solve a problem. Image: https://favpng.com/png_view/stock-photography-royalty-free-mechanical-engineering-3d-computer-graphics-png/MgU3sdb9
What problem was Mr. Bohlin trying to solve? His job was to make cars safer for people. In the 1950 s lots of cars did not have seat belts. If a car did have a seat belt, it went across the person s lap and attached at 2 points. Nils Bohlin knew about a science called physics and Newton s First Law of Motion. He used that knowledge to think about how to create a better seat belts for cars. Image: http://clipart-library.com/images-of-a-car.html
Lets learn about Newton s First Law of Motion What is Newton's First Law of Motion? The Dr Binocs Show https://www.amazon.com/The-Dr-Binocs-Show/product-reviews/B079TCPGMN?reviewerType=all_reviews
Inertia A New Word Let s share. What did you say? In your own words, talk to a friend about what inertia means. Image: https://www.istockphoto.com/photos/stick-figure-friends
Lets pretend! Pretend you are in car. How would you move in your seat if the car was starting to move? How would you move in your seat if the car turned to the right? How would you move in your seat if the car stopped? Image: http://clipart-library.com/free/cartoon-car-transparent-background.html
A new type of seat belt! 3 Nils Bohlin designed a seatbelt for cars that attaches at 3 points. 2 1 Image: https://hotcore.info/babki/seat-belt-safety-logo.htm
Seat belts in cars! Today, every car MUST have seat belts. Because of science, millions of lives have been saved by people wearing their seat belt. Millions?! That is a big number!
How big is a million? 1 = ONE 10 = TEN 100 = ONE HUNDRED 1000 = ONE THOUSAND 10000 = TEN THOUSAND 100000 = ONE HUNDRED THOUSAND 1000000 = ONE MILLION ONE MILLION IS A BIG NUMBER SEATBELTS HAVE SAVED MILLIONS OF LIVES! https://www.swoopanalytics.com/blog/question-mark-analysis
Mr. Bohlins Favorite Message Don t forget to buckle up. Reference: The New York Times, https://www.nytimes.com/2002/09/26/business/nils-bohlin-82-inventor-of-a- better-seat-belt.html Image: https://www.media.volvocars.com/uk/en-gb/media/photos/6487
Remember to always wear your seat belt. Seat belts and Science Saves Lives! Image: https://avatarms.com/buckle-message-people-forgo-seat-belt/
Teacher Notes: Nils Bohlin Summary: Engineers use science to solve problems, like helping to keep people save in cars. Nils Bohlin designed the 3-point seat belt saving millions of lives. This lesson also includes Newton s First Law of Motion (Inertia). Lesson Length: 30 minutes Next Generation Science Standards (NGSS): K-2-ETS1-1.A Before beginning to design a solution, it is important to clearly understand the problem. K-PS2-1 Motion and Stability: Forces and Interactions PS2.A Forces and Motion Pushes and pulls can have different strengths and directions. Pushing and pulling on an object can change the speed or direction of its motion and can start or stop it. PS2.B Types of Interactions When objects touch or collide, they push on one another and can change motion. Common Core State Standards (CCSS) Math: C.CC.A.1 Count to 100 by ones and by tens. K.CC.B.4 Understand the relationship between numbers and quantities; connect counting to cardinality.
