So I was showing a group of kids recently how to learn about the life cycle of a butterfly using food. Usually I use a butterfly snack cake to represent the butterfly stage. They also make butterfly shaped crackers….but you can only find the crackers and snack cakes in the spring time. So what do you do if you are doing the experiment in the fall? In this case, I came up with something similar to pictures I had seen before, and I created this:

I filled a sandwich bag with grapes and carrots, and then divided the bag using a pretty hair barrette (you can use whatever you want: barrette, clothes pin, pretty ribbon, whatever you can think of that would divide the bag in half). So there you go: a nice, healthier alternative to try when you can’t find what you need. 🙂 Or if you just want something a little less sugary.

Edible Experiment: Colors of the Rainbow September 25, 2017

Posted by Tori in Edible Science Experiments.

Area of Science: Physics

Materials Needed: Multicolored licorice

Background: What are the colors of the rainbow?

In order, the colors are: red, orange, yellow, green, blue, indigo, and violet, or ROY G BIV.

Why? Why are the colors in the order they are in? When white light is scattered (like in a prisim, for example), it divides into colors. These are colors that we see, which is part of the electromagnetic spectrum. The light we see is only a small part of the spectrum known as visible light. They break down according to wavelength. Red has the longest wavelength (and lowest frequency) at around 700 nanometers. Violet has the shortest wavelength (highest frequency), around 400 nanometers. Beyond those ranges, we get out of the visible light and into ranges the human eye can’t detect.

Instructions:

  1. Separate out your colors. Line them out in order to make a rainbow. (Red, orange, yellow, green, blue, indigo, violet).
  2. Enjoy!

Note: You may only be able to find 6 out of the 7 colors when it comes to licorice. Indigo is a color that is somewhere between blue and purple, and may not be available as a licorice color. (I know I couldn’t find one in that color). If you can’t find a separate licorice rope in that color, just make your rainbow with the other 6, or see if you can find two different shades of blue or purple.

For older children: For older kids, you can explore more in-depth with the frequencies and wavelengths associated with each color.

Edible Experiment: “Magic” Floating Raisins January 16, 2017

Posted by Tori in Uncategorized.

Hi! Finally getting back to posting some fun experiments. A little while back, my pastor decided to take a page from my book, as it were, and try a Children’s sermon you can eat. He floated a raisin in soda (only he had trouble making it float….but that’s a different story, lol). So I decided to put it up here to explore the science of it. Enjoy! 🙂

Instructions:

Take some raisins, and drop them one at a time into a cup of clear soda. It may take a few, but you should be able to get at least one to float.

What’s going on?

The bubbles in the soda cling to the raisins, causing them to rise to the surface. Once the bubbles reach the surface, they pop. The raisin then sinks again, only to rise again.

So it’s been a while since I last posted an experiment. I’ve been busy putting together all my experiments into a book. My good friend, Renae, with Armonia Publishing, will be publishing my new book: Play with your Food…for Science!

I first met Renae 8 years ago when we moved into the house across the street from hers. Now she and her husband own a publishing company, and will be publishing my book sometime next spring. Can’t wait til then? Then check out the sample here.

In the mean time, keep experimenting, and play with your food…for science! 🙂

Edible Experiment #28 August 29, 2016

Area of Science: Physics
Age Range: preschool and up
Materials Needed: Water
A syringe

Background: The boiling point is the temperature at which a liquid transforms into a gas. In the case of water, the boiling point is 100 degrees Celsius (212 degrees Fahrenheit). Pressure can affect the temperature at which something boils. As you lower the pressure, the boiling point lowers. This is the reason cookbooks will give instructions for higher altitude.

Instructions:
Using the plunger, pull a small amount of water into the syringe. You only need enough that you can see what’s going on. Don’t fill it completely.
Turn the syringe upside down, with plunger facing down. Cover the opening with your finger or some kind of air tight cap.
Pull the plunger down. You should see tiny bubbles start to form inside the liquid. It may take a few tries to get it to work well enough that you can observe it.

Area of Science: Biology/Environmental Science
Age Range: All ages can appreciate this experiment
Materials Needed: 1 box chocolate pudding
Your favorite chocolate cookies
Gummy candy critters (gummy worms, snails, etc-no gummy bears)
Background: The dirt in your yard is actually an entire ecosystem. The topsoil is home to all kinds of bugs and other critters: ants, earthworms, snails, etc. In this experiment you will be “building” a topsoil ecosystem.

Instructions:
1. Mix pudding according to package directions. Layer into dessert cups.
2. Crumble the chocolate cookies. Sprinkle over pudding to form a 1/4” think layer.
3. Add your gummy critters on top.
4. Enjoy!

Note: I actually used Jello’s Dessert Creations Oreo Dirt Cake box kit, but pudding and cookies will work just as well.

Edible Experiment #18 March 28, 2016

This is another experiment my husband and I came up with to explore buoyancy and Archimedes’ Principle.

Area of Study: Physics
Age Range: Jr. High school and up
Materials Needed: an egg
a bowl
a cup

Background: Archimedes’ Principle states that the buoyant force on an object submerged in fluid (whether fully or partially submerged) is equal to the weight of the fluid the object displaces. In mathematical terms, the formula is:
F=ρgV
where F is the upward buoyant force, ρ is the density of the fluid, g=9.81 m/s² (the pull of gravity), and V is the volume of the fluid displaced. If the weight of the displaced liquid is less than the weight of the object, it will sink. If the weight of the fluid is equal to or greater than the weight of the object, then the object will float.

Instructions:
1. Fill the cup with water (ρ=1) all the way to the brim. Carefully place cup in the bowl.
2. Gently place the egg into the cup. The water displaced will overflow into the bowl.
3. Carefully remove cup from bowl, and measure the water displaced.
4. Hard boil the egg in a pan of water. Once cooled, repeat steps 1-3.

SONY DSC

Questions: Was there any difference between the hard boiled egg and the raw egg? Which one displaced more water? Why do you think this was?
If you have a kitchen scale, you can weigh the eggs and see if there is a weight difference between the two.

Note: You can use this to test if an egg is still good. A good egg will sink in water, while a bad egg will float. Why do you think this works?

Edible Experiment # 15 March 7, 2016

Area of Science: Physics
Age Range: middle school and up
Materials Needed: 4 small boxes or 2 large boxes red gelatin dessert
2 1/2 cups boiling water
Mixing bowl
Measuring cup
13’x9’ pan
Graph paper
Red laser pointer
Knife

CAUTION: This experiment requires the use of a low-powered laser pointer. Do not shine the beam in anyone’s eyes or look directly into the beam, as that could cause eye damage. Use precautions when using the laser.

Directions:

  1.  Mix gelatin with boiling water. Stir to dissolve.
  2.  Pour into pan. Chill in refrigerator for several hours.
  3.  Cut a square of gelatin using knife. Set aside.
  4.  Place the laser pointer on the graph paper so that the beam will line up with one  of the grid lines. Tape the laser in place.
  5.  Place the gelatin square on the graph paper at a 45 degree angle to the laser  beam.
  6.  Shine the laser through the gelatin. Observe what happens.
  7.  Change the angle of the laser beam in relation to the gelatin. What happens?
  8.  Experiment with other shapes: circles, semicircles, triangles, concave and  convex lenses. How does each shape affect the path of the laser beam?

DSC07095.JPG

Analysis: When light travels from one material to another (where the two materials have a different index of refraction), it changes path. The index of refraction is a number that describes how light moves through a particular material. Normally we can’t see what path the light takes unless the light bounces off of something like dust or pollen in the air. Because gelatin has tiny particles that reflect the light, we are able to see the path of the laser beam through the gelatin. This is the same affect as when you stick a straw in water and the image of the straw seems to bend when it hits the water.

Further Study for older kids: This is a good way to help older kids understand how lenses work. This is the same principle optometrists use for figuring out eye glasses and contacts. There are two types of lenses:

  1. Concave lenses (positive lenses)—Concave lenses will converge, or focus light and form an image
  2. Convex lenses (negative lenses)—Convex lenses will diverge, or spread out, light rays

If one knows the distance from the object to the lens and the focal length of the lens, it is possible to calculate how far from the lens the focused image should be using the Thin Lens Equation:
(1/d) + (1/d’) = (1/f)
Where d is the distance between object and lens, d’ is the distance between lens and image, and f is the focal length of the lens.
