1. “Have you ever ridden a roller coaster?” “What was it like?” “What do you think makes a roller coaster exciting?” Write down a few ideas.
2. Explain that you are going to watch a video about how roller coasters are designed. The students first watch the video till 2:04 and decide whether the sentences in 1 (bottom right corner, the start of the roller coaster on the worksheet) are true or false. Ask the students to provide the right information if the sentence is false. Listen to that part of the video again if needed.
KEY: a. FALSE (He wasn’t the first one, but he popularised them.); b. TRUE; c. FALSE (It was 18 miles long.); d. FALSE (It opened in 1884.)
3. Listen to the four main components engineers take into account when designing roller coasters by watching the video till 2:46.
4. Ask the students to follow the track of the roller coaster on their worksheet to complete a number of activities:
– Component 1: Train cars. In their own words, the students explain how train cars are kept attached to the tracks.
– Component 2: Track design. Here four key words are provided. The students listen and write down why they are mentioned in the video.
KEY: a. steel (Most roller coasters are made of steel nowadays.); b. 4 minutes (“Steel Dragon 2000” takes 4 minutes to complete.); c. sick (The way people might feel if the roller coaster is too fast.); d. boring (People will find roller coasters boring if the ride is too slow.)
– Component 3: System to raise the cars. The students complete the sentences with six words as they listen.
KEY: a. gravity; b. pulley; c. crest / is released; d. beneath / conveyor
– Component 4: Braking system. The students join several sentence halves in the best way possible.
KEY: 1. b; 2. d; 3. a; 4. c
5. How about having the students try and design their own roller coaster? At its very simplest, you may want to stick to the more creative part of it and have teams design a roller coaster they would enjoy using some of the information in the video (and at least make it as safe as possible!):
1. What do you want to achieve with your design? What kind of audience will it target?
2. Where will you build your roller coaster?
3. What kind of theme will it have?
4. Try to use as much information from the video as you can when designing your roller coaster!
The teams then present their designs and the group discusses whether they would work or not, taking physics and safety but also fun into account!
If you want to provide some further reading, the students may benefit from this user-friendly website that allows them to build their own roller coaster. They first decide on the height of the first hill, the shape of the first hill, the exit path, the height of the second hill, and the loop. The website will then check whether the ride is possible or not!
Enjoy the ride!
