Ramp Lab (Conclusion Discussion) Debbink Physics 2023-08-31 | This video discusses the CONCLUSIONS we reached for the Ramp Lab. The Ramp Lab is an investigation of objects that change their velocity while moving in a straight line. Below are the videos that can be used to collect data for spinners at different angled inclines. All 15 videos have an object that increases speed. Some of the videos show the increase in speed while moving in the positive direction, and others show the increase in speed while moving in the negative direction. Some videos have the object start with an initial velocity, while others show the object starting from rest. If you are a teacher you can use different groupings of videos based on what you would like the students to learn when analyzing the position and velocity data collected from the videos.

Egg Drop 2022 (AP Physics 1) Debbink Physics 2022-09-17 | This is a lab challenge AP Physics 1 students completed at the end of a unit on one-dimensional motion and free fall. The goal was to have the egg hit a moving target (me!), moving at a constant speed. The students needed to calculate the amount of time the egg would take to fall to the height of the helmet, and estimate the amount of distance I would cover in that same time. Each group then placed a cup at that calculated distance away from a target right below their release point. As I walked past their measured cup, they would release the egg, so that I reached their target just as the egg reached my head height!Sound effects obtained from zapsplat.com
Modeling Instruction Lab (Kinetic Energy and Velocity) Arbor Scientific Collaboration Debbink Physics 2022-07-29 | In an introductory physics class, students need to have a quantitative understanding of the relationship between the velocity of an object and the stored kinetic energy. Rather than directly giving your students this equation, give your students an experience where they can develop this equation through a guided investigation. This video walks you through an introductory physics lab that allows students to develop a model for the relationship between an object’s kinetic energy and velocity. This guided investigation will allow students to develop the kinetic energy equation, where the kinetic energy of a moving object is equal to one-half times the object’s mass times the velocity squared.

Shot VS Drop (Physics of Projectile Motion) Debbink Physics 2022-07-21 | This is the classic physics thought experiment: if you fire a gun horizontally and drop a bullet from the same height, which will hit the ground first? Another way to ask the question is how does the vertical part of a "shot" or horizontally launched object's motion compare to the behavior of a dropped object? This video shows a small steel ball released from the edge of a table the same instant another steel ball rolls off the edge. It is clear that vertically they behave the same! Both balls have a vertical acceleration of -9/8m/s/s. If you are interested in collecting data about the launched ball's horizontal and vertical positions for further analysis, see the 3 linked videos below...Projectile Investigation #1 (Slow Speed): youtu.be/5tYd96TZOwEProjectile Investigation #2 (Medium Speed): youtu.be/YiEOW9Ew5BUProjectile Investigation #3 (Fast Speed): youtu.be/pJj9IUadjJs

2D Standing Waves with Sand (Variable Frequency) Debbink Physics 2022-07-14 | Basic Description:In this video a metal plate with loose sand on its surface is disturbed at different frequencies using a function generator. At particular frequencies there are two-dimensional "standing waves" which get created on the metal's surface. A standing wave has regions of large up and down displacement called "anti-nodes" and other regions which do not get displaced up and down called "nodes". When a standing wave is created in the metal surface, the loose sand will move away from the anti-nodes and toward the nodes, the regions which do not shake up and down.The frequencies which create standing waves in a material are known as resonant frequencies.To learn more about the physics of resonance and "standing waves" see the video below...Standing Waves Introduction: youtu.be/wBEkFva64TEThe equipment was provided by Arbor Scientific (arborsci.com)Music: bensound.com

Modeling Instruction Lab (Newtons 2nd Law) Arbor Scientific Collaboration Debbink Physics 2021-10-11 | In an introductory physics class, students need to have a quantitative understanding of the relationship between the motion of objects and the forces they experience. This comes in the form of Newton’s 2nd law of motion. Rather than directly giving your students this equation, give your students an experience where they can develop this equation through a guided investigation.In this video, I will walk you through a lab that allows students to develop a model of the relationship between an object’s acceleration and its mass.Featured Blog: bit.ly/2XTrz5ADownload the Acceleration Lab Guide: bit.ly/3imfhu3Featured Products from Arbor Scientific- Fan Cart: bit.ly/3AfqjIO- Slotted Mass Set with hanger: bit.ly/3kBRNSa- Digital Newton Meter: bit.ly/36vF50t- Whiteboard 6 Pack: bit.ly/3j6o4S0Join the CoolStuff Insider List: bit.ly/34HbfVO--Video Chapters0:00 Video Introduction2:11 Prelab Discussion5:13 Data Collection6:58 Data Analysis10:27 Conclusion Discussion
Egg Drop Lab Challenge (AP Physics 1) 2021 Debbink Physics 2021-09-27 | This is a lab challenge AP Physics 1 students completed at the end of a unit on one-dimensional motion and free fall. The goal was to have the egg hit a moving target (me!), moving at a constant speed. The students needed to calculate the amount of time the egg would take to fall to the height of the helmet, and estimate the amount of distance I would cover in that same time. Each group then placed a cup at that calculated distance away from a target right below their release point. As I walked past their measured cup, they would release the egg, so that I reached their target just as the egg reached my head height!
Modeling Instruction Lab (Mass and Weight) Arbor Scientific Collaboration Debbink Physics 2021-09-15 | Students often have a hard time distinguishing between the concepts of mass and weight. In their minds, the words are interchangeable. Walk down any grocery store aisle, and this confusion is only reinforced by the labels included with food products. The packaging has units of grams and ounces next to one another. Doesn’t this mean these numbers are measuring the same thing? Watch as Aaron Debbink, a high school physics teacher and Modeling Instruction workshop leader since 2011, walks you through an introductory physics lab that helps students separate the concepts of mass and weight and uses experimental data to build a model of the relationship between the two variables.

AP Physics 1 (Off the Grid Day) Slip-n-Slide 2017 Debbink Physics 2021-03-15 | This was the activity chosen by one of my AP Physics 1 classes for our class's "Off-the-Grid Day" in 2017. Students used a bicycle generator to power an electric blower which was used to inflate a small blow up pool. The students also built a small wooden ramp and placed both at the end of a slip-slide. Off-the-Grid day is the final day of a unit on energy and power free from the use of conventional electricity. The students get to create and implement a fun activity, but whatever activity they design and choose must involve at least one device that runs on electricity, and that electricity must be supplied solely by a bicycle generator. The energy must be stored in a battery beforehand and then used on our “Off-the-Grid Day”. Each lab group designs an activity, calculates energy needs, and estimates the amount of time it would take to store the needed energy using a bicycle generator. After the proposed activities are presented, each class votes for their favorite. The winning proposal then becomes that class's “Off-the-Grid” day activity”, but we will only do the activity if the students work together to come in before and after school to store the needed amount of energy in a car battery using a bicycle generator. For an overview of the whole design project see the following...Off-the-Grid Day Project Summary: youtu.be/-LzH_SHlRCc
