Classroom Traffic Lights vs CloudLabs Elevator Load

Traffic Lights for the classroom is a great way for teachers to get instantaneous feedback on whole class learning. Just 3 ways (there are many others) the app can be used are: 1. A means of whole class formative assessment to determine student learning. e.g. how do you feel you have understood adding negative integers? Red: not grasped the skills yet. Amber: not sure if they have understood the intended learning or feel part way there. Green: feeling confident they understand the intended learning. The teacher can then differentiate their teaching by grouping the students. 2. A means of whole class formative assessment to determine attitudes towards an opinion, idea or statement. e.g. "school uniform policy must be adhered to at all times", or "this is a love poem". The teacher can then group like minded students to develop their arguments further or ask random students to explain their position. 3. A classroom management tool. Features: * Supports all iPad and iPhone devices * Supports iOS 12.0 and later * Beautiful large crisp clear graphics make the visuals perfect for classroom use. You'll be able to see this no matter the size of the class. No ads, no in-app additions, just pure function. If you want to see more in the app, please contact PKCLsoft at support@pkclsoft.com

In this laboratory you will find a scale model of an elevator car. The goal of this lab is to apply Newton's second law to find the mass ratio between the car and the counterweight, and get the car to travel with a desired acceleration. For this purpose, the free body diagrams and the sum of forces must be carried out, in addition to finding the tension force of the cable, the weight of the car and the weight of the counterweight.
