Homemade Projector

This time we were studying THE EYE in Natural Science and we decided to make something related doing a Homemade Projector. We could experiment with the orientation and the size of the images that changed depending on the magnifying glass

Materials: Shoe Box, cardboard and paintings (for decorating), Magnfying glass, scissors, celo tape, white paper, smartphone.

1. Trace the shape of the magnifying glass on one of the short sides of the box and cut it out

2. Decorate the box

3. Tape the magnifying glass on its place

4. Place the smartphone inside the box, with the sceern looking at the magnifiying glass, and play a video in the highest resolution and brightness that you can and close the box.

5. Use a white paper in front of the projector to see the image.

We had to play moving the smartphone closer or further to the magnifying glass and do the same with the paper to find the perfect spot to see the image big and focused. We also realized that the magnifying glass turns the image upside down, like the lenses of our eyes do.
