Build a communication system for the Moon
Learn about how electronic intercom circuits can help players communicate
In this activity students will gain an understanding of how soundwaves travel and are received to allow them to be heard in the ear. Building on students pre-existing knowledge of circuits this activity focusses on how football players on the Moon could communicate to each other using electronics. Students then apply their skill to build an intercom circuit.
This resource uses the theme of football on the Moon to allow learners to develop their knowledge and skills in design & technology, mathematics and science. In this activity learners will use the theme of football on the Moon to learn about how electronic intercom circuits can help players communicate.
Activity: Build a communication system for the Moon
The teacher will introduce the activity and explain how sound waves allow us to hear. The teacher will then discuss the problems communicating on the Moon and explain why an electronic circuit is necessary. Learners will then have the opportunity to manufacture and test their own intercom.
This activity can be simplified (particularly for less able students) by placing components onto the PCB/stripboard prior to soldering and/or using helping hands to hold PCB/stripboard in place.
As an extension learners can research what methods could be used to make the intercom wireless.
This activity is designed to take between 40-60 minutes.
Tools/resources required
- Paper cups and string
- Sharp pencils and sticky tack
- Electronic components (see PPt list on slide 7)
- Soldering irons and stands
- Helping hands
- Wire strippers and cutters
- Lead free solder
- PCB making kit
- Tracing paper to print PCB mask
- Stripboard (see PPt slides 16-18)
- Stripboard track cutters
The engineering context
Engineers create and develop communication systems for numerous activities that take place in very different environments. For example, deep sea divers need to communicate underwater and armed forces have to communicate in all weather conditions.
Suggested learning outcomes
By the end of this free resource students will be able to understand how hearing works translating sound waves; understand how sound waves can travel through string by vibration and wire by electrical signal; and be able to build an intercom circuit.
