This week we are continuing our exploration of light. We are seeing how light can go through water and magnify just like a magnifying glass. A magnifying glass uses a piece of glass called a lens to make things appear closer than they are. A magnifying glass works because light bends when it moves from the air through the glass lens. This is called Refraction.
What you will need:
- Small clear plastic bag (with zip top)
- Page of writing (from newspaper or magazine)
What to do:
- First, write down some of the words from the newspaper or magazine in your journal. Be sure to make them the size you see.
- Then pour a small amount of water into the corner of the plastic bag.
- Carefully hold the water-filled corner of the plastic bag over the piece of newspaper or magazine. Look through the water at the words on the page. Write down the words in your journal, the size they appear when you view them through the water.
How does it work?
As we saw in last week’s experiment, the water slows down light and makes it bend. In this experiment, the water in the bag bends the light almost like a magnifying glass does, so the words on the paper look closer, (therefore, larger) when we read them through the water.

We would love to see you doing the experiments!
