How strong you should hit a ball to break a glass?

General Physics I (Phys 1433, Phys 1441)

Activity Description: Provide a brief description of the activity

The Project is based on the work of Pyotr Kapitsa, who was famous physicist and Nobel laureate. (https://en.wikipedia.org/wiki/Pyotr_Kapitsa)
He published book “Problems in Physics”, which include problems for discussion. These problems did not give all conditions and details for a solution, so a student can choose them.
One of such problem is: “What must be the speed of a tennis ball that can break glass?”
I modified a little bit this problem and student should find an answer on a question “How strong you should hit a ball to break a glass?” (What force should be applied)
To find an answer students should use all Physics laws and principles from a semester (Physics I) and to choose all conditions what they need for the solution.

Learning Goals: What do you aim to achieve with this activity?

What should student use during the project:
Physics
Imagination
Abstract and critical thinking
Understand how and which questions to ask
Basics of engineering design
Analytical thinking and mathematical calculations
Technical/report writing
Backward thinking
Calculation in a new soft/web program
Working with data
Working in a group

Timing: At what point in the lesson or semester do you use this activity? How much classroom time do you devote to it? How much out-of-class time is expected?

This project is one thirds of a semester. Students should do it at home. All steps would be describe during class time and all questions would be discussed in a class.

Logistics: What preparation is needed for this activity? What instructions do you give students? Is the activity low-stakes, high-stakes, or something else?

Students will have step by step instructions for this project.

Assessment: How do you assess this activity? What assessment measures do you use? Do you use a VALUE rubric? If not, how did you develop your rubric? Is your course part of the college-wide general education assessment initiative?

CRITICAL THINKING VALUE RUBRIC, PROBLEM SOLVING VALUE RUBRIC, WRITTEN COMMUNICATION VALUE RUBRIC, READING VALUE RUBRIC, CREATIVE THINKING VALUE RUBRIC (Project with wide borders for advance level of the course)

Reflection: How well did this activity work in your classroom? Would you repeat it? Why or why not? What challenges did you encounter, and how did you address them? What, if anything, would you change? What did students seem to enjoy about the activity?

Student are interested in the project, they ask a lot of questions. The assignment requires a good level of knowledge and some students have difficulties. In this case more time for a discussion should be during a class.

Activity Description: Provide a brief description of the activity

I created a few Jeopardy games to do in-class review for the midterm and final exams; this is an example of them. I split the class in two teams and they play the game by choosing the category and points; all members of the winning team usually get extra credit.

Learning Goals: What do you aim to achieve with this activity?

There are both course-specific and gen-ed learning goals. On the one hand, we get to review content for upcoming exams. On the other, I hope that students get a chance to improve their teamwork skills, boost their confidence, and just simply see that science can be fun in many ways.

Timing: At what point in the lesson or semester do you use this activity? How much classroom time do you devote to it? How much out-of-class time is expected?

I have used it before midterm and final exams and usually allocate about 30 minutes of class time.

Logistics: What preparation is needed for this activity? What instructions do you give students? Is the activity low-stakes, high-stakes, or something else?

The students don't need to prepare besides their usual pre-exam review; there is a small amount of extra credit awarded but I would still think that this is a low-stakes activity meant to increase their confidence and have fun.

Assessment: How do you assess this activity? What assessment measures do you use? Do you use a VALUE rubric? If not, how did you develop your rubric? Is your course part of the college-wide general education assessment initiative?

The grading is immediate and it usually just results in an EC point for the winning team.

Reflection: How well did this activity work in your classroom? Would you repeat it? Why or why not? What challenges did you encounter, and how did you address them? What, if anything, would you change? What did students seem to enjoy about the activity?

I started proposing this activity in class following a student's suggestion on a midterm survey, and after speaking about it with a friend who has been teaching in high school and told me about the website to create the games. It was very popular and I would always do it if I had the time – unfortunately I always feel that time is such a precious resource that I need to also use more traditional review methods (I always give a mock exam) and I am not always able to do it. Students appreciate the novelty of it and the fun aspect – many do enjoy a healthy level of competition.
