Lesson Plan
Pre lesson preparation:
- Divide students into groups (each consists of 3) and place and stick on each table the metric ruler so that students can use it as a reference at the test, and highlight a starting point.
- Place a LEGO Education WeDo 2.0 kit on each table with a laptop/tablet, along with one Student worksheet per group and some extra papers, pens.
In class lesson steps:
- Start your lesson as shown in the Teachers manual for the speed lesson by LEGO education by playing the Video at first and then discuss the idea of the racing cars that are used in contests as following:
- Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition .In auto racing, the racing setup or car setup is the set of adjustments made to the vehicle to optimize its behaviour (performance, handling, reliability, etc.). Adjustments can occur in suspensions, brakes, transmissions, engines, tires and other factors.
- Speed is the rate of motion, or the rate of change of position. It is expressed as distance moved (d) per unit of time(t). As in SI units, it's meters/second.
- Acceleration is defined as the rate of change of the speed. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second².
- Introduce the lesson for the students as they are Engineers in a car manufacturing factory and their mission today is to report what are the changes that we can do to make the car model prototype made from the LEGO Education kit go faster. Inform the students that in this lesson they will be given a 15 minutes to build the car instructed in the software( From the Guided projects menu -Speed and skipping directly to the Build phase, and inform students to ignore adding the motion sensor as it will not be used ) and then ask all students to program as following so that the electrical features are all the same and only the mechanical configurations will be adjusted during the test:
