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 Potential and Kinetic Energy If you have never used my Kesler 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. You can read my complete guide to how run effective station labs on my blog. 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.
Kesler Science Station Lab Potential and Kinetic Energy Teacher Directions Explore It! I will spend much of my time at this station making sure students are understanding the concept. You will need a few toothpicks, a few pieces of pipe insulation (any hardware store), and a few marbles. The insulation can be cut with a razorblade to make two pieces of track. The toothpicks hold multiple pieces together. Organize It! All of the cards are included for this station. The cards for this activity are attached near the activity. Students should be encouraged to do the Research and Explore station before attempting this one. I like to label the backs with set numbers because they will get mixed up. Place this one next to the Explore It! Station. Illustrate It! Make sure to include colored pencils or crayons 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 YouTube and my Google drive.

Potential and Kinetic Energy A roller coaster ride is a thrilling experience which involves a wealth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor (or other mechanical device) exerts a force on the train of cars to lift the train to the top of a vary tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation. At the top of the hill, the cars possess a large quantity of potential energy. Potential energy - the energy of vertical position - is dependent upon the mass of the object and the height of the object. The car's large quantity of potential energy is due to the fact that they are elevated to a large height above the ground. As the cars descend the first drop they lose much of this potential energy in accord with their loss of height. The cars subsequently gain kinetic energy. Kinetic energy - the energy of motion - is dependent upon the mass of the object and the speed of the object. The train of coaster cars speeds up as they lose height. Thus, their original potential energy (due to their large height) is transformed into kinetic energy (revealed by their high speeds). As the ride continues, the train of cars are continuously losing and gaining height. Each gain in height corresponds to the loss of speed as kinetic energy (due to speed) is transformed into potential energy (due to height). Each loss in height corresponds to a gain of speed as potential energy (due to height) is transformed into kinetic energy (due to speed).

Safe B. Moving C. Stored D. Potential Another word for kinetic energy could be energy. Using the diagram on the reading, at which point would the cars be losing potential energy and gaining kinetic?

Watch It! Station Directions Each member of the group will go to the website listed on task card #1 Complete the task cards in order. Every student will answer the questions from the task cards on the lab sheet in the Watch It! section of the lab sheet.
Study Jams: http://goo.gl/n44trj URL is case-sensitive 1. Click Play on the video. 2. Answer questions from cards #2-4 on your lab sheet. What is energy? Study Jams What is the difference between potential and kinetic energy? After watching the video describe a situation where an object would have potential energy transformed into kinetic energy?
Research It! Station Directions Each member of the group will go to the website listed on task card #1 Complete the task cards in order. Every student will answer the questions from the task cards on the lab sheet in the Research It! section.
1. Go to http://goo.gl/fwiuwz 1. Press PLAY to watch the rollercoaster go through the track. 2. Press STEP to see the rollercoaster stop at each different stage. 1. On your lab sheet describe what is happening to the energy along each of the 6 steps of the rollercoaster.
Explore It! Station Directions One member of the group will read the task cards in order. The group will be responsible for completing each of the tasks that are being read. Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.
1. Use the two foam pieces and toothpicks to make a rollercoaster at least 1 meter tall and has a loop after a big drop. 2. See if you can make the marble go through your coaster. Answer the following on your lab sheet. 1. Draw a diagram of your coaster. 2. What is the force that causes the ball to move? 3. Why does the ball eventually stop? Gravitational Potential Energy is energy that is stored due to its positon. At the tallest part of your rollercoaster the marble has the most potential energy. When the mass of the marble is increased the potential increases. 1. Label PE (potential) on your diagram. Kinetic Energy is the energy of motion. Near the bottom of the tallest hill on your rollercoaster the ball will be moving the fastest, therefore it will have the most kinetic energy. 1. Label KE (kinetic) on your diagram.
The law of conservation of energy says that energy cannot be created or destroyed, only transformed. As the ball rolls down the hill the ball is losing potential energy but gaining kinetic energy. This is an energy transformation. 1. Label PE going down and KE going up on your diagram. Answer the following on your lab sheet. 1. As the coaster goes back up the second hill what is happening to the energy? 2. Where would you also see mostly potential energy in your model?
