Click here for a small video clip. You can show this to your students as an introduction to this WebQuest and as an introduction to the force and motion. Click The Law of Inertia to read more about the Law of Inertia. The class can also watch a 2 minute video about roller coasters and Newton's Laws. The link is here and in the introduction.
To bring in a larger crowd, management at Fiesta Texas is searching for the latest thrilling roller coaster. This "king of the park" will be a new and exciting ride that will defy gravity and mystify the mind. This will be the newest attraction in years. Who can design such a roller coaster? This is where you come in.
You are a Mechanical Engineer for Fiesta Texas. As a mechanical engineer, you will research as much as you can about Newton’s Laws and apply your research to the design of a new roller coaster. You will be in charge of designing the next 'king of the park.' Before you move on, click here to watch a video on roller coasters.
Students will eventually answer, What does Newton’s Laws have to do with a roller coaster?
This is a Web Quest designed for 8th grade students on the topic of Newton’s Laws. Before setting off on the quest students need to be comfortable with:
1. Using a computer
2. Navigating the Internet
3. Working with Internet resources
4. Taking notes from electronic sources and collecting data
5. Setting a purpose for reading
6. Synthesizing information across resources
7. Collaborating with their peers on a project
8. Map pencils, scissors, additional lined or copy paper
9. 5- 10 toy cars, preferably small cars
10. 10- 15 balloons
Did you know that roller coasters do not have engines? So how do they move so fast and go up side down? Roller coasters move by gravity and inertia. The taller and higher a roller coaster is, the more gravity will pull it closer to earth. As you go through the WebQuest, you will read about Newton's Laws. Then you will apply what you have read and create a roller coaster on poster board, computer, sketch drawing, or 3- D construction. The choice will be up to you because you will be able to explain how Newton's Laws are demonstrated.
Before you move on, click for a Vocabulary Review.
Review with teacher- students can create a quick foldable
to log vocabulary. The foldable can be as followed: Have students fold
paper evenly down the middle so that the paper can fold in half, as if
the students were taking a spelling test. With a ruler, students can draw
up to 17 lines across the one side of the paper. Then students can write
out the vocabulary word on the outside of the paper, and the definition
on the inside of the flap of the paper that was cut. Students can color
coat the boxes of definitions with the flap with the vocabulary word.
This part can be done as a whole class or group activity. Click the link
for students to write out vocabulary words. Students are to include the
The vocabulary words students will be focusing on are listed below:
Newton's Laws of Motion Period
Students can work in groups of four, or this can be a whole class activity. To save on time, the teacher can complete the 3 demonstrations mentioned in Step 1, Step 2, and Step 3.Each student will still be responsible for all of the work the steps ask for.
Teacher information written in bold lettering:
The teacher can have handouts printed before the lesson begins.
Students will use their handouts titled Law 1, Law 2, and Law 3, and the links below to complete their objectives.
Attached is a copy of the links primarily available to
the teacher. The students have access to fewer links.
For additional activity, students can complete Newton's
Log during the WebQuest. They will answer the following questions:
- Describe the state of motion and inertia fit from the example: someone lying on the couch.
- Describe acceleration and force from this example: a ball thrown between two people.
- Describe equal but opposite reaction from this example: a rocket flying into space.
These pages carry information students can use to complete the tasks.
Pre-reading activities can also be useful for reading electronic text. Consider having students use the title, subtitles, and divisions within the text to predict content. Look at pictures, maps, diagrams, or graphs and their captions to enhance understanding. Skim to find the theme or main idea.
Students will not be asked to do any mathematical calculations in this web quest. The roller coaster designs are not expected to be mathematically accurate. Students should demonstrate a basic understanding of roller coaster design, such as, the first hill must be the highest hill because it must be able to provide enough energy for the train to complete the entire course of the coaster. Loops need to be teardrop shaped instead of a perfect circle because of the g forces that act upon the riders' bodies. The teacher can specify to the students what principles he/she expects to see demonstrated in the coaster drawing. These principles should mirror the information covered in the class prior to this project.
Step 1: (1 day) Mini-lesson on Synthesizing
Newton's First Law- An object in motion stays in motion.
To better understand Newton's First Law, you will need a toy car, and
a partner. Think about this: An object in motion stays in motion. What
does this mean?
Have about five feet of space between you and your partner. Now facing each other, roll the car across the floor towards your partner letting it travel as far as it can without stopping. The car will roll until it runs out of energy or until something stops it from rolling like an object in the way. This is an example of Newton's First Law: An object in motion stays in motion.
Think about this next example:
Since an object in motion stays in motion, comets can fly around in space forever, because they are in motion. Until something comes in the way, the comet will keep going.
Grab your handout First Law and complete it using the links on the resource page. For a mini lab on inertia, click here. This can be printed and sent home for homework or done as a class project, or how ever chosen by the teacher.
Step 2: (1 day)
Newton's Second Law - The Law of Acceleration and Force
To better understand Newton's Second Law, you will need a toy car, and
a partner. Think about this: The greater the acceleration, the greater
the force, the greater the mass the greater the force. What does this
If you have one object and apply a little force versus applying a lot of force, the object will move faster with more force. For example, with your toy car, apply force to the car so the car will travel as far as possible. You will do this by pushing the car back and then rolling it with a lot of force. See how far it will go. How far did your car go? Have your partner do the opposite and apply little force to the car. Does the car travel further then the your partner's car?
Think about this next example: if you were pushing a one ton elephant on skates with little force, it would move slowly. If you push the same elephant with a lot of force, it will move quickly. This is an example of Newton's Second Law: The greater the acceleration, the greater the force; the greater the mass, the greater the force.
Now you will complete the Second Law of your handout. Click here for the links to complete this step.
Step 3: (1 day)
Newton's Third Law - The Law of Interaction
To better understand Newton's Third Law, you will need a balloon and a partner. Think about this: For every action there is an equal but opposite reaction. What does that mean?
Go outside for this demonstration. With your balloon in your hand, blow the balloon up with as much air as possible. Then let the balloon go. As you let the balloon go, watch it howl through the air as it descends to the ground. Think about what you just did. The amount of air you blew into the balloon was then evened out by how it soared all through the room, spitting with air until it landed. Now have your partner bow air into the balloon, but do not fill the balloon up all the way. Let the balloon go and observe if the balloon traveled with as much intensity as your partner's.
Think about this next example: "Imagine a rocket is being launched from the earth. Hot gases are pushed out from the bottom of the rocket as the rocket is thrust upward. The force of the gases pushing against the surface of the earth is equal and opposite to the force with which the rocket moves upward. The motion of the rocket can be explained by Newton's third law, for every action there is an equal but opposite reaction." (Westbroek, 2000, Utah State Office of Education)
Think about these examples as you answer your Third Law handout. Click here for the links to complete this step.
For an excellent demonstration of Newton's Third Law, click here. Students will be able to work with alka seltzers and 35 mm canisters for a hands on experiment.
Step 4: (1 day) Mini-lesson on Summarizing
Now you are probably wondering how Newton's Laws and
rollercoasters have in common. They have lots in common! You can read
coaster link to How Stuff Works for any last minute details for your
Click on the summary. You will type out a summary of what you have learned about Newton's Three Laws. When you finish your summary, move onto the roller coaster link. There you will read through the link and create a computer model roller coaster.
Step 5: (1 day)
