Science is a fun way to learn the basic principles of how the world works. School can only teach so much and when you get to the point where the teacher allows you to go out on your own, you can become stuck or confused, especially with physics. This article will show you how to conduct a simple physics experiment using magnifying to determine the magnified size of an object versus its actual size.
Things You'll Need
- Large magnifying glass
- Scotch tape
- Black marker
- Wax paper
- Twist tie
- Drinking straw
- Small chunck of clay
- Small objects to magnify
Building a Magnifying Physics Project
Place a strip of Scotch tape on the wax paper.
Lay your ruler along the piece of tape and mark off the centimeters and millimeters on to the tape with the marker.
Cut out a piece of tape that fits within the diameter of the magnifying glass and stick it directly on the lens.
Bend the straw in half around the ruler and twist tie the ends together. The ruler should be able to slide from side to side.
Tape the handle of the magnifying glass to the ends of the straw.
Jam the ruler into the chunk of clay to act as a stabilizing base.
Conduct the Experiment
Collect the items to measure.
Create a table and have space to record name of item, actual measurement, height of lens and optical size.
Measure the size of an item and record it in the "actual measurement" column.
Put an item in front of your device, under the magnifying glass.
Move the magnifying glass up the rule to where you would like to start. Record this starting position under the "height of lens" column.
Look through your magnifying glass at the item and use the tape to determine the optical size of the item and record that in the appropriate column.
Change the height of the magnifying glass and record the new findings.
Repeat Steps 3 through 7 until each item has been recorded.
Tips & Warnings
- When complete you can prepare a graph that shows your findings.
- Physics is not a simple science so take great care in your surroundings when conducting experiments.
