Goldland Choo choo Rail / Science Diary / Teaching Tools / After School Materials / Goldberg | 10.5 ( 60.00) |
Discounted amount of your subtotal will appear when you place your orders.
The weight changes the direction the marble goes
"Choochoo Rail"
Material
Corrugated cardboard, Plastic, Rubber, Steel
Components
Main rail, Rail fixing board, Rail support, Switch, Guard rail, Snap button, Weight fixing board,
Weight support, Weight bolt/nut, White sticks, Rubber ring
One of Goldberg's connectors.
It is a device that changes the direction of movement of marble using weights.
The ball rolls toward the weight and hits the weight and drops it, then changes direction and the ball rolls to the next device.
Marbles falling from the F-1 wave board activate the choochoo rail to operate the F-3 rubber car.
'Choo choo Rail' Principle of Science
Gravity : The force by which objects on the earth are drawn toward the center of the earth.
Inertia : The force by which objects on the earth are drawn toward the center of the earth.
Potential energy by gravity : The property of an object trying to continue in a state of stationary or constant motion unless it is subject to external forces.
1 step. Make a main rail
① Fold the main rail by the folding line as shown in the figure and fix it with snap button. (Three)
② Secure the guard rails on both sides of the main rail.
*Fix it by aligning the main rail end groove with the guard rail groove.
③ Fix the weight support by inserting it into the groove and guard rail groove at the end of the main rail.
2 step. Make a rail fixing boards
① Fold the rail support along the fold line and fix it with snap button.
② Place the main rail on the rail support.
*Insert white stick into groove and fix both sides with rubber ring.
③ Fold the rail fixing board along the fold line.
④ Fold as shown and fix both sides with snap button.
3 step. Make a switch
① Fold the switch along the fold line and secure it with the snap button.
② Put the switch on the rail fixing board.
③ Insert the white stick into the groove and fix both sides with rubber ring.
4 step. Complete the Choochoo Rail
① Fold the hooks on top of the rail retaining boards and place them upright.
② Insert the fixed board hook into the bottom groove of the rail support.
③ Fold the weight fixing board in half, pass the weight bolt and fasten it with a nut.
5 step. How Choochoo Rail Works
① Hang the weight on the weight fixing board at the back of the main rail.
6 step. Connect with Goldberg devices
① Install the F-1 wave board next to the completed choochoo rail.
*You can move the waveboard to determine where the marble fall.
② Connect the F-1 wave board, the F-2 choo choo rail, and the F-3 rubber car to activate the device.
7 step. Using Choochoo rails in various ways
① The choochoo rail can be used in various ways without the rail fixing board.
② This is how the rails work.
