Learning is Fun

The mystery of crystals

For grades 4 and 5

A crystal is a special kind of solid material. Growing crystals introduces you to change and variation. When certain liquids and gases cool and lose water, crystals are formed. Crystals are made up of molecules that fit neatly together in an orderly package. All crystals of the same material have the same shape, regardless of their size. Enjoy this fun activity to learn more about how crystals form.

What You Need

  • Magnifying glass
  • Table salt
  • Epsom salt
  • Honey container
  • Measuring cups and spoons
  • Safety scissors
  • Pencil
  • Colored pencils

What to Do

  1. Use a magnifying glass to look for crystals. Take a look at the table salt, the Epsom salt and the honey container (particularly if it has been open for awhile). Draw pictures using colored pencils of the crystals that you see.
  2. Dissolve the salt crystals and form new ones. Dissolve 1 teaspoon of salt in 1 cup of water. Heat the mixture over low heat to evaporate the water.  Be careful!

Things to think about:

  1. Do all of the crystals look the same? If not, how are they different?
  2. What shape are the crystals in?
  3. Can you think of anything in nature that is made up of crystals?

Part of a strong body is a strong mind! These homework tips will help you improve your grades and impress your teacher while making learning more fun.

  1. When you are ready to do homework, find a quiet place with plenty of bright light. Turn off the TV and music to help you concentrate.
  2. Gather all the supplies you will need, such as paper, pencils and a dictionary or special art supplies for projects.
  3. Do your homework at the same time each day. Try not to wait until too close to bed time.
  4. Be sure to read the directions your teacher gives you before you start a project.
  5. Work on hard homework first, then easy homework. This will help you get through the tough stuff while you have the most energy.
  6. If you are getting frustrated or having trouble, try taking a short break, and then try again.
  7. Some schools offer tutors who are a little older than you and who can help you after school. Or you can always ask an adult for help, too.
  8. Have a positive attitude! This will help homework time go by faster.
