Read each section carefully and complete the activities to learn about the amazing simple machine called a ramp!
Activity 1: Vocabulary Match-Up
Draw a line to match the science word on the left with its correct meaning on the right.
| 1. Ramp | A. A push or a pull. |
| 2. Force | B. The force that resists motion when two surfaces rub against each other. |
| 3. Work | C. Another name for a ramp; a flat supporting surface tilted at an angle. |
| 4. Inclined Plane | D. Using force to move an object over a distance. |
| 5. Friction | E. A simple machine with a sloping surface, used for raising heavy objects. |
Activity 2: How Ramps Work
A ramp helps us do work by making it easier to move things up or down. But there's a trade-off! Fill in the blanks below using the words from the word bank to explain how.
A ramp makes lifting an object 1. _______________. This is because you use less 2. _______________ to push or pull the object up the slope than you would to lift it straight up. However, you have to move the object over a 3. _______________ 4. _______________. The gentler the slope of the ramp, the less force you need, but the path becomes even 5. _______________.
Activity 3: Ramp Facts: True or False?
Read each statement below. Circle T if the statement is true or F if it is false.
- T / F 1. A very steep ramp requires more force to push something up than a long, gentle ramp.
- T / F 2. Ramps only help with moving objects up, not down.
- T / F 3. Stairs are a type of ramp.
- T / F 4. Ramps increase the distance you have to move an object.
- T / F 5. A perfectly smooth ramp would have zero friction.
Activity 4: Ramps in Your World
Ramps are all around us! Think about your home, school, and community.
1. List three examples of ramps you have seen or used:
- a. ___________________________________________________
- b. ___________________________________________________
- c. ___________________________________________________
2. Critical Thinking: A moving company is loading a heavy piano onto a truck. They have two ramps they can use: one is very short and steep, and the other is long and gradual. Which ramp should they choose and why?

ANSWER KEY
Activity 1: Vocabulary Match-Up
1. Ramp → E. A simple machine with a sloping surface, used for raising heavy objects.
2. Force → A. A push or a pull.
3. Work → D. Using force to move an object over a distance.
4. Inclined Plane → C. Another name for a ramp; a flat supporting surface tilted at an angle.
5. Friction → B. The force that resists motion when two surfaces rub against each other.
Activity 2: How Ramps Work
- easier
- force
- longer
- distance
- longer
Activity 3: Ramp Facts: True or False?
- T (True)
- F (False - They also help control the speed of an object moving down.)
- T (True - They are a set of small ramps/steps.)
- T (True)
- T (True - Although in the real world, this is practically impossible to achieve.)
Activity 4: Ramps in Your World
1. List three examples: (Answers will vary). Examples could include: wheelchair ramp, skate park ramp, slide at a playground, loading ramp on a truck, driveway slope, a slanted path or sidewalk.
2. Critical Thinking: They should choose the long and gradual ramp. This ramp requires less force to push the heavy piano, making the job easier and safer, even though they have to push it over a longer distance.
