Hello Spring Break, I've missed you. It's been too long....
Goals: SWBAT...
1. Answer the following question: Momentum - Is it conserved in an explosion?
Warm-Up (5min): Consider a system with two carts. Cart 1 is moving to the right with a momentum of 125kgm/s & cart 2 is stationary. Both carts have a mass of 125kg each. The collide, stick together, and roll to the right.
1. What is the final momentum after the collision?
2. Find the final velocity (post collision) of the carts
CLASSWORK
1. #052C: Is momentum conserved during an explosion?
- 4 minutes to complete any leftover bits
2. #053A: Quiz Grading
3. Extra Credit
At Home Learning (HW)
1. Extra Credit Options (you can do a max of two):
- Build your own models of the six simple machines, including all three types of levers (so 8 machines total). Any medium may be used (including a 3D printer). Be prepared to bring in your models, and explain your models to the class. Up to 20 points
- Build a Rube Goldberg Machine in your home that uses all 6 simple machines (including at least 2 different types of levers) to pour cereal into a bowl. Video your project (with your face viewable in the video) and load on the following website to share with others: https://diy.org/skills/physicist/challenges/389/make-a-rube-goldberg-machine Be prepared to present your video to the class. Up to 25 points
- Here's another video showing some suggestions for how to go from concept to successful build of a machine. It's a blog post meant for teachers, but it could be useful for you as well... :) http://steampoweredclassroom.com/sum-up-how-to-do-a-rube-goldberg-project-and-not-lose-your-mind/
- Some info on Rube Goldberg (man, myth, legend), Simple Machines, and the six types of simple machines, is here: https://media.rubegoldberg.com/site/wp-content/uploads/2017/10/HumdrumDay-LessonPlans-2.pdf
- Write a children's book that explains the six simple machines. This book must be typed and include illustrations. The illustrations can can be clip art, images from on-line, or your own artistic creations. Be prepared to read your book to the class. Up to 20 points
2. You can make up any missing CW/HW from the past week, study for any quizzes you did poorly on (so you can retake them), and make up missing warm-ups.
Have a great spring break :-).
