Candy Chromatography
The Skittles in water experiment can also lead to another exciting activity called candy chromatography. After the Skittles have dissolved, you can use the leftover liquid to separate the different dyes present in the candy.
To perform candy chromatography, you will need:
- Coffee filter paper
- A glass or jar
- The liquid from the Skittles in water experiment
Here’s how you can conduct candy chromatography:
- Cut a strip of coffee filter paper.
- Dip one end of the strip into the liquid from the Skittles in water experiment.
- Place the other end of the strip into a glass or jar, ensuring that the strip is suspended and the end does not touch the liquid.
- Wait for several hours, or overnight, as the liquid travels up the strip, separating the different dyes in the candy.
- Observe the colorful patterns that appear on the filter paper as the dyes separate.
This experiment allows you to explore the concept of chromatography and learn about the different components that make up the colors in the candy. It’s a fun and educational way to delve into the world of chemistry!
| Candy | Dissolving Color |
|---|---|
| Red Skittle | Red |
| Orange Skittle | Orange |
| Yellow Skittle | Yellow |
| Green Skittle | Green |
| Purple Skittle | Purple |
This table shows the color that each Skittle will dissolve into when performing the Skittles in water experiment. It can help you observe and compare the colors as they dissolve in the water.
Enjoy the vibrant and captivating Skittles in water experiment, and take it a step further with candy chromatography to explore the fascinating world of color mixing and dissolution!
Colour Changing Potions
Experience the magic of color-changing potions with this exciting science experiment. By using a red cabbage indicator, kids can create a potion that transforms its color based on the pH level. This experiment is not only visually captivating but also teaches children about chemical reactions and the concept of acidity and alkalinity.
The Science Behind Color Changing Potions
Color changing potions rely on the red cabbage indicator, a natural pH indicator that changes color depending on the pH level of a solution. The red cabbage contains pigments called anthocyanins, which have different colors under different pH conditions. When combined with baking soda or vinegar, the red cabbage indicator undergoes a chemical reaction that causes a color change.
How to Create Color Changing Potions
- Prepare the red cabbage indicator by blending red cabbage with water and straining the liquid.
- In separate containers, mix the red cabbage indicator with baking soda and vinegar.
- Observe and record the color changes that occur when the two substances react.
- Experiment with different ratios of red cabbage indicator, baking soda, and vinegar to create different colors.
Red Cabbage Indicator Color Chart
| pH Level | Color |
|---|---|
| Highly acidic | Red |
| Acidic | Pink |
| Neutral | Purple |
| Alkaline | Blue |
| Highly alkaline | Green/yellow |
Candy Chromatography
Discover the marvelous world of candy chromatography, a captivating science investigation that unravels the secrets of dyes found in candy. With just a few simple materials like non-washable felt-tip pens, filter paper, and water, your kids can embark on a colorful experiment that demonstrates the separation of dyes.
To start, gather some candy of different colors and select a few non-washable felt-tip pens in corresponding hues. You’ll also need filter paper strips and water. Begin by drawing a small dot of ink from each pen on separate strips of filter paper. Next, place a small piece of each candy on separate filter paper strips. Make sure the dots of ink and candy pieces are positioned above water, without touching it.
Now, carefully pour water into a cup or bowl, ensuring the level doesn’t reach the dots of ink or candy. Observe as the water is drawn up the filter paper, carrying the dyes with it. You’ll witness a mesmerizing display of colors as the dyes separate and travel up the filter paper at different rates. This phenomenon occurs due to the varying solubilities and molecular sizes of the dyes present in the candy.
You can also explore a fun twist on this experiment by using the candy itself for chromatography. Simply place a piece of candy on a filter paper strip and add a few drops of water on top. Watch as the candy colors separate and percolate up the filter paper, revealing the individual dyes within.
Encourage your kids to make observations and record their findings in a notebook or create a data table to document the order of dye separation and the colors they observe. This hands-on activity not only sparks curiosity but also teaches valuable lessons about scientific investigation, separation techniques, and the properties of different dyes.
| Dye Color | Order of Separation |
|---|---|
| Red | 3rd |
| Blue | 2nd |
| Yellow | 1st |
Unlock the vibrant world of candy chromatography and empower your child with the knowledge and excitement of scientific exploration. They’ll be delighted by the magical transformation of colors and gain a deeper understanding of the separation of dyes. Through this engaging experiment, they can unleash their creativity and curiosity while building a strong foundation in the wonders of science.
