“CATCH THE FUTURE ”ACTIVITY PLAN
In which case and how do we use the situation in the example above? What features
should the tool you design?
When sound waves hit a rigid obstacle, they are reflected and reflected. This is like
throwing the ball towards the opposite wall and coming back to you.
Have you ever witnessed your voice coming back to you when you shout as the
child did? Sometimes you may have experienced a similar situation in an empty and
big enough room.
This phenomenon, called echo, occurs when sound hits a surface and returns. This
way the sound comes back to the environment where the sound comes from indicates
that the sound is reflected as well.
Learning process
The reflection of sound is the basis for the operation of many tools in technology.
One of the tools made using the reflection feature of sound is the ultrasound device
used for imaging of internal organs. With this device, sound waves are sent to the
internal organs that the human ear cannot hear. Sound waves are reflected in different
amounts and shapes from each organ. In this way, images of internal organs are
obtained. Early diagnosis of some diseases is possible with ultrasound. Sonar is
another tool developed by the reflection of sound waves. By using the sonar device,
data such as size and distance of an object can be obtained. Fishing vessels can easily
locate the shoals of fish in the sea using sonar. Submarines can also travel safely
thanks to sonar.
Now, using the reflection of sound, we will design our digital meter with our
arduino materials. First of all, I would like you to design our distance meter which
provides the best distance measurement with the materials that can be used. You will
then decide to make a joint product based on your drawings within the group. Please
try to agree in-group for the product you will design. The spokespersons will present
the products decided by the groups to the class respectively.
Product development:
1. Students are required to be divided into groups of three and to move to a seating
arrangement.
2. The students are asked to investigate the situation and share the results with the
