Chemistry Experiments for Hands-On Science Fun!

chemistry experimentsMaking cookies on a Sunday afternoon is a wonderful way to get busy working with various ingredients, measuring liquids and solids, and estimating how to pinches to throw in here and there.  However, we have a better idea for you.  The next time you whip out a bag of chocolate chips — try making some edible green slime out of pudding!  And if that is not enough, what about some oven baked ice cream or a cup of lava?  These are both fun and educational spins on household activities great for you and kids alike. If any of these ideas sound good, then it looks like you are in the mood for creating some some fun and interesting chemistry experiments!  There is something exhilarating about creating science experiments, probably because you are taking some rather normal (usually) ingredients and creating something cool and seemingly “dangerous” while learning chemical properties, physical reactions, and changes in matter at the same time.  If you are in the mood to tickle your scientific self, we have got some interesting, cool, and rewarding chemistry experiments for you to try out!

Purpose

Without further ado, let’s dive right into the experiments.  Remember that chemistry experiments serve a purpose.  Aside from being a lot of fun and a hands on way to deal with what you are learning, a chemistry experiment will allow you to dig deeper into the topic you are studying.  Let’s get started!

Mentos Soda Volcano

Purpose:

This eruption of chemistry will show how carbon dioxide gas found in soda can cause a “volcanic eruption” when you add some mentos candy to the mix.

What you will need:

  • An open area outdoors.  Be prepared to get a little bit messy.
  • 1 Roll of mentos candy (mint flavored)
  • 1 2-liter bottle of diet or regular soda.  If you are aiming for a high eruption, go for diet.
  • 1 narrow test-tub that is wide enough for the mentos to fit comfortably into.  If you do not have a tube, feel free to use a piece of paper and fold it into a tube.
  • 1 index card.

Procedure:

  1. Get your test tub or paper tube and begin to stack the mentos on top of each other inside.
  2. Take your index card and place it over the top of the test tube or paper tube.  Then, flip the tube over so that the index card is now at the bottom and keeping the mentos from falling out.
  3. Shake your 2-liter bottle of soda a little bit and remove the cap.
  4. As soon as the soda bottle opens, you should experience an explosion, so be ready!  Right away, place the mentos roll over the bottle’s opening with the index card on the top.  Quickly remove the index card.  Your mentos will fall into the bottle one by one.
  5. Take a few steps back to watch your volcano erupt.  It should shoot the soda a few feet into the air!

The Translucent Egg

Purpose:

Want to create a regular food item into a translucent particle that light can pass through?  This experiment of the translucent egg will show you how to create a “naked” looking egg through the process of a chemical reaction that will breakdown the egg’s calcium and erode its shell.

What you will need:

  • 1 large egg (or 1 for each person doing  the experiment)
  • 1 large glass jar, or a tall drinking glass
  • 1 bottle of white vinegar
  • 1 pen or pencil
  • journal or notebook to record your results

Procedure:

  1. Take your raw egg and place it into your jar or drinking glass.
  2. Take your vinegar and pour it into the jar or glass so that it completely submerges your egg.
  3. Leave your jar or glass with the egg in a safe place where it can remain undisturbed for 24 hours.
  4. After 24 hours, take a look at your egg.  Record what oyu see in your journal.  (Hint: you should see tiny bubbles beginning to accumulate onto the eggshell).
  5. Now, take your jar or glass and drain the vinegar.  Use a strainer while you do this, or be very careful so that your egg does not drop!
  6. Once your jar or glass is drained, refill it with vinegar so that you will completely submerge the egg once again.
  7. Again, place your jar or glass in a safe and undisturbed place for 48 hours, or about 2 days.
  8. After 48 hours, take a look at your egg and note your observations.
  9. Again, carefully pour and drain the old vinegar from the jar or glass.
  10. Remove your egg from its jar and rinse it under cold water.  Take a look at your egg — it should be translucent!  The shell should be gone and the egg should be left with its membrane.
  11. Record your results.

chemistry experimentsLava Lamp

Purpose:

In this experiment, you will be able to demonstrate the effects that salt has on oil by creating a mysterious and magical looking “lava lamp” in a cup.

What You Will Need:

  • 1 or more teaspoons of salt
  • Tap water
  • 1/4ths cup of olive or vegetable oil
  • Food coloring (your color of choice)
  • 1 large clear glass
  • 1 eye dropper (only if your food coloring is not already in a dropper)

Procedure:

  1. Fill your glass about 2/3rds full with tap water.  Leave enough space to fill the rest of the cup with your oil.
  2. Take your 1/4ths cup of oil and pour it slowly into the glass of tap water.  The oil should be concentrated at the top of the water.  Do not attempt o mix the oil and water together.
  3. Take your choice of food coloring and add several drops into your glass of water and oil.
  4. Now, take 1 teaspoon of salt and slowly sprinkle your salt into the glass.  Take note of what happens when the oil and water mix together!
  5. Feel free to add several more drops of different colors of food coloring for a cool effect!

Green Slime

Purpose:  This slimy experiment will show that you can mix two chemicals together to form slime, or your very own “Flubber”!

What You Will Need:

  • 1 bottle of White Wood Glue, such as Elmer’s brand.
  • Broax power (typically found in the laundry section of a supermarket).
  • Green food coloring
  • Water
  • 1 Tablespoon
  • 1 Teaspoon
  • 2 bowls or containers
  • 1 airtight container or Ziploc bag to hold your slime.

Procedure:

  1. Take you container and inside, mix together: 1 tablespoon of glue, 1 tablespoon of water, and 1 drop of green food coloring.
  2. In your other container, take 1 teaspoon of your Borax powder and dissolve it in 1 tablespoon of water
  3. Now, take your Borax solution and pour it into your first container of glue mixture.
  4. Using your fingers, mix together the two solutions until they are combined.  You should form a green slime!
  5. Take note of what occurred and then store your slime in an airtight container or Ziploc bag, as to avoid any mold growth.

Put On Some Protective Goggles!

There is a lot more to Chemistry than learning formulas and memorizing the periodic table.  Chemistry experiments can translate what you learned into exciting and rewarding hands-on experiments that can show you how different particles and substances can react in different environments — and create things such as slime!  Try your hand at some of these experiments to make learning fun, and be sure to check out Udemy.com to further supply any of your Chemistry needs!
