Force-Driven Car_Textbook Edition Fourth Grade Science_Motion and Force_Self-made Teaching Aids

Force-Driven Car, can be driven by pulling force, gravity, wind force and magnetic repulsion, change the driving mode by replacing modules

Textbook Edition:Suitable for Textbook Edition Elementary School Fourth Grade (Upper) Science

Teaching Objectives:
  Cognitive Objectives: Have a clear understanding that different types of forces can all cause objects to move
  Ability Objectives: Understand that force is the cause of object motion, and be able to grasp common types of forces that drive object motion
  Affective Objectives: Through more intuitive and interactive experiences of scientific phenomena for students, enhance students' interest in science courses

Production Method
1. This kit contains four parts: body, gravity module, wind force module and magnetic force module.

2. Assemble the body: Install the four axles on the bottom plate of the car, and then install the four wheels on the axles to complete the assembly of the car.

3. Assembly of the magnetic part (optional): Use pliers to press the magnet into the magnetic card and the magnetic pusher.

Usage
1. Demonstration of pulling force drive:
(1) Place the pull bar in the snap

(2) Snap the snap diagonally on the central axle of the car

(3) Press the snap so that it is flat against the central axle of the car

(4) Demonstrate driving the car forward by pulling force

2. Demonstration of gravity drive:
(1) The assembly process is similar to that of pulling force drive, the only difference is that two wheels need to be inserted into the pull bar as weights before installing the pull bar (the number of wheels can be changed to obtain different sizes of gravity).

(2) Show the driving effect of gravity by placing the weight on the edge of the table

3. Demonstration of wind force drive:
(1) Remove one axle of the car

(2) Insert the sail component diagonally, rotate the sail component so that it is flat against the main axle.

(3) Reinstall the axle and drive the car with natural wind or blowing (the sail can be bent appropriately to enhance the driving effect)

4. Demonstration of magnetic repulsion drive:
(1) Remove one axle of the car and insert the magnetic plug diagonally

(2) Rotate the magnetic plug so that it is flat against the main axle. Then reinstall the axle.

(3) Use the magnetic pusher to push the car, showing the magnetic repulsion drive of the car (attaching more magnets to the pusher can enhance the pushing effect)
