Activity 2.2 : Catapult Schematic

Activity Description

Students learn to create a visual representation of a system by drawing a schematic for the catapult.

Getting Started

Introduction:

E.Q.: How does air flow through the pneumatic catapult?

Preparation Needed for the Activity:

- Catapults
- Paper and colored pencils for schematic drawings
- Teacher Only Solutions to the Catapult Tip Sheet
- Catapult Parts Quiz sheet

Part 1 - Review Terms: 10 min

Use the Catapult TIP Sheet from the previous activity to review terms:

Tank (reservoir), solenoid, regulator, shut-off valve, switch, power source, actuator

Part 2 - Draw a Schematic: 25 min

The students will examine their catapult, and draw a schematic of it. A schematic is basically a ‘map’ of how the system works. It should include the key components, labels, and connections between the components. Air flow between the components should be indicated with an arrow. More advanced students should also indicate the flow of electricity from the battery to the solenoid.

Have a few students share their schematics with the class using the appropriate vocabulary.

Part 3 - Test Your Understanding: 5-10 min

Administer the Catapult Parts Quiz to the students. This could be a ticket out the door activity.
