Did you know that you can turn your smartphone or tablet into a Microscope? Here’s How…
Light allows us to see objects. It reflects off an object and projects an image onto the retina of our eyes, which our brain then interprets. But, if we bend the light, we can change how the object projects. We can make the object bigger or smaller, or even distort the image completely. By using a lens (a curved piece of transparent material, usually plastic or glass), we can manipulate the light to make an object appear closer or larger.
In this activity, we will combine the camera lens already found in a smartphone or tablet, with a second lens to make a microscope (a tool to see (scope) small (micro) things).
Directions:
OPTIONAL – only needed if step 3 was unsuccessful) Using the wire cutters, carefully cut notches into the sides of the top, loosening the hold on the lens (use caution and adult supervision here… alternatively, students can attempt to work the lens loose with the bobby pin and tweezers. It’s important not to scratch the lens, however.)
Turn the top upside down on a firm surface and gently bang the top against the surface until the lens comes loose. You can also attempt to work the lens loose with the bobby pin or tweezers. Be sure not to scratch the lens, however.
Turn on your device and access the camera function.
You will need to adjust the magnification and blurriness of objects in two ways, first by using the zoom-in function of your device’s camera and second by adjusting how far away you hold the device from the object you are attempting to view. (This is similar to using the focus knob on a traditional microscope).
Use your makeshift-microscope to explore the microscopic world around you! When you are ready to look at specimens, use a specimen slide just as you would with a traditional microscope.
