Description
"Slope" PPT
Part 1: Step-by-step learning
1. Create scenes to stimulate interest.
1. Ask questions.
2. Make guesses about the problem.
2. 1. Introduce the simple machine - inclined plane.
(Concept learning)
2. Raise inquiry questions. (The purpose is to stimulate students' desire to conduct experimental operations and conduct experimental verification.)
3. Independent learning and cooperative inquiry.
Experimental program
Experiment name: Study the effect of inclined planes
Experimental equipment: Incline (wooden board), weight (car), dynamometer
Experimental steps:
1. Set up the experimental device.
2. First measure the force that directly lifts the object, and then measure the force that lifts the object along the incline.
3. Discuss and organize experimental findings.
Kind tips:
1. When reading the force that directly lifts an object, keep your eyes at the same level as the dynamometer.
2. The requirement of pulling the dynamometer is to move in a straight line at a constant speed and read while pulling.
3. Pay attention to group cooperation and record while experimenting.
Part Two: Knowledge Application
The pattern on the screw is a deformation of the bevel. It wraps the bevel around the cylinder and stretches it out to form a bevel. It is used to help the screws drill into the wood when rotating. The denser the texture, the easier it is to save effort.
The zipper cleverly uses the bevel principle to combine or separate two rows of interconnected chain teeth. The slide buckle of the zipper is made up of several wedges. When you pull it, it can convert a small force into a large force to open or close the zipper.
After-school exploration: When a person encounters an uphill slope while riding a bicycle, how can he ride more effortlessly?
