Design a device using light to communicate over a distance - 1st Grade Science

Jeanette should use the traffic light as a model for her design. It is a successful device that uses lights to keep people safe and could be a good way for her to come up with ideas for her design.

The best object to start with if designing a device that uses light for communication would be the flashlight. The flashlight can be seen long distances, turned on and off, and can be flashed to send messages. A radio is excellent for communicating with sound but not light, and a mirror reflects light, but it doesn't make it's own light if you needed to communicate at night.

The best design plant would be "A bright sign that lights up from the inside and says "Yummy Tacos" in big, bold letters" because it would meet the design requirements. It would attract customers, be easy to see, uses light, and can be seen from a distance. Stores and restaurants use light to attract customers with their street signs, open signs, and colorful decorative lights.

The lights on the runway are intended to communicate where the safe place is for the plane to land. If it were to be improved, there could be more lights, brighter lights, and they could be added to both sides. Planes landing at night rely on these lights to get passengers to the ground safely. Part of the design process is making improvements on existing devices.

Both crosswalk screens and elevator buttons use light to send us a message. We can tell if the elevator is going up or down based on the lights, if the button for our floor has been pressed, or if the elevator is stuck based on the lights. A crosswalk will show us a hand or a walking figure when we need to stop or if it is safe to cross. It will also count down, so we know how long we have.

Waving a flashlight at night is a similar device to the lighthouse shining out to sea at night. Planes land in the dark and need to see the runway edges so they can line the plane up. Workers who wave the flashlights help keep the passengers and crew safe by letting the plane know where to land.

The traffic light's purpose is to keep us safe and help drivers know when to go, slow down, or stop. You or your teacher could design a similar device to use in the classroom. The teacher could shine a red light to stop working, a green light to start working, and a yellow light for time is almost up. This would communicate the messages a teacher might share with light rather than sound.

This is an excellent example of how light can be used to communicate messages! Aly can use her laser pointer like a finger and point at the letters to spell her name or words to send the class a message. Without using sound, Aly can communicate to her teacher what she is thinking with this simple device!

You and your brother could come up with a secret code to communicate using a device like a lamp. Two clicks could mean no, one-click yes, and so on until you have a whole language. Messages are passed with light every day, thus creating your device to communicate is something that anyone can design.

This is a true statement. Light is used to communicate and send messages every day. Everyday crosswalk signs, lighthouses, traffic lights, and so many more help to send messages to people all around. Light is made of waves, and we can use these waves to keep people safe and pass information.
