Tyler's Model: Focuses on objectives, content, learning experiences, and evaluation. Taba's Model: Emphasizes starting with questions from students' experiences and leading to broader concepts. Wheeler's Model: Centers on the process of planning, implementing, and evaluating curriculum. Bruner's Model: Stresses the importance of spiral curriculum, where concepts are revisited and built upon over time.
To build a roller coaster using craft sticks and a hot glue gun, start by designing the layout of the coaster. Use the craft sticks to create the track and support structure, securing them with hot glue. Be sure to test the coaster as you build to ensure it functions and can support a small toy car. Add loops, curves, and other elements for excitement.
The shape of a rose flower is known as a logarithmic spiral, which is a type of spiral that grows by equal factors in every direction. This spiral can be described mathematically using the equation r = a * e^(b*theta), where r is the distance from the center of the spiral, theta is the angle of rotation, and a and b are constants. The petals of a rose flower grow in this pattern to optimize exposure to sunlight and facilitate pollination.
Whenever one object exerts a force on a second object the second object exerts an equal and opposite force on the first. Since a roller coaster is on a ramp, the ramp has to support the (apparently larger) weight of the roller coaster, especially when it turns it back up against gravity at the bottom of each incline. The rollers on each car also prevent the cars from leaving the track on turns, by exerting a controlling force using the sides and upper half of the track.
A simple model involves using thermocol. Drawing water cycle on its surface.
You could buy a k'nex roller coaster, Icoaster, RCT3, Nolimitscoaster or just make one using wire for supports and use aluminum foil for the track.
The advantages of using a bicycle with a coaster brake system include simplicity, low maintenance, and the ability to brake by pedaling backward.
A roller coaster can accelerate using an electromagnetic field or linear motor. Another way for a roller coaster to accelerate is by using a hydraulic launch method. using cables to catapult the ride forward.

A roller coaster can accelerate by using gravity, propulsion systems, or magnetic forces. Gravity pulls the coaster down slopes, propulsion systems like motors or launch systems provide additional speed, and magnetic forces can propel the coaster forward using magnetic fields.

A bike with a coaster brake functions by using the pedals to stop the bike. When you pedal backward, the brake engages and slows down the bike. The advantages of using a coaster brake system include simplicity, low maintenance, and the ability to brake without taking your hands off the handlebars.
Brakes, either using friction or magnets, are used to slow down or stop the train usally at the end of a roller coaster ride.

It is easier to see this using a traditional roller coaster model. Most traditional Roller Coasters start by using a tow cable to pull them up a large "hill". When being pulled up this hill, mechanical energy is being used to give the roller coaster potential energy. At the top of this hill, the roller coaster has it's maximum potential energy. As it starts to go down another hill, it picks up speed. During the descent it is losing potential energy but at the same time gaining kinetic energy. The coaster will then lose kinetic energy but gain potential energy as it goes up the next hill. This cycle of gaining/losing potential and kinetic energy is the conservation of energy that you are looking for. Of course in a real roller coaster, some energy will be lost due to friction. This will come off as heat in the rails and the wheels of the roller coaster and it's structure.
The roller coaster seen in that commercial is Boomerang at Knott's Berry Farm. Using that, I'm assuming it was somewhere in southern California.
