Teaching children chemistry can become a fun, at-home activity as a weekend afternoon project or as part of their remote learning curriculum. One of the best experiments you can do is the mixing activity. With this exercise, children will learn the difference between soluble and insoluble substances. Do not worry! You can do it with ingredients you already have in your kitchen!
Before you begin the activity, ask the children what each ingredient is - whether it is a solid, liquid, or gas - and what they think will happen when you begin mixing them. This guarantees a hands-on experiment that will allow the children to feel they are in control. After these mixing activities, you can further this experiment by letting the children find other ingredients to mix with water and have them determine if that substance is soluble or insoluble.
The main goal is to show them different reactions and layers. For a clear example of this experiment, check out this video. Experiment courtesy of Dr. Stephanie Ryan.

Then, dip a cotton swab in dish soap and place it in the middle of the dish. The colors will begin to swirl and seem as though they are moving on their own! Explain to your kids that the soap reduces surface tension and makes the fat molecules in the milk move.

Check out the video for details. You can get in on the action yourself by blending your own custom bubble mixes. Then you can experiment to see which produces the biggest, strongest, and most colorful bubbles. You need only a small amount, though, so check the bulk food section. Instructions Make the Basic Formula 3 cups water 2 tablespoons dishwashing soap. Just a little bit of a key ingredient can make a huge difference in your bubbles! See for yourself by testing the different formulas. Label each formula so you can note its particular strengths and weaknesses.
Bubbles burst when they dry out, so adding glycerin can make them last longer. Most formulas call for about 2 teaspoons per batch, but for extra-strong bubbles, experiment with adding up to 4 tablespoons 2 ounces per batch.
You can achieve that by adding a small amount of a polymer, such as guar gum, a food thickener. For more about polymers, see What's Going On, page Mix the paste into the water, then add the dishwashing soap, and give everything a good stir.
Take It Further Some bubble formulas call for baking soda, which is said to improve the performance and stability of larger bubbles. This acidic cooking powder changes the pH of the mix to make it more neutral.
Add this after adding the guar gum, water, and dish soap, then cap the jar and turn it over to blend everything together. Can you observe any difference in your bubbles? For more tips and expert advice, check out Soap Bubble Wiki online, where you can read reviews of mixtures, see amazing photos, and learn more about the role of various ingredients.
Water alone is not stretchy enough to hold the air, but a mix with dishwashing soap is elastic, like a balloon. Bubbles pop when the water on their surface evaporates or touches anything dry. Adding a humectant, such as glycerin, to your mix slows down evaporation, making the bubbles last longer. Adding a polyme, makes the bubbles far more elastic so they can stretch to huge sizes. What to Watch For See how long the bubbles last, how strong they are, how high they fly, even how colorful they are.
Try them indoors and outdoors, on a calm day and a windy day. See how each formula works when you use a big wand or a small blower see Homemade Bubble Wands, opposite. The brand of dishwashing soap you use can have a big impact on your final mix. Dawn and Joy are recommended, so if your bubbles are not performing well, try one of those. Tell Me More Since bubbles pop from evaporation, the best time to blow them outdoors is when the air is calm and muggy, such as after a rain shower.
On colder days, however, your bubbles may fly higher, because your warm breath is lighter than the cold air. In extremely cold weather, you can watch your bubbles freeze into ice orbs or watch it on YouTube. And if you really want your bubbles to last, keep them in a sealed jar with a little bubble solution on the bottom. Famous bubble entertainer Eiffel Plasterer Google him! By adding more or less sugar to each water solution you are creating different density levels.
When you add coloring to the glasses you will be able to see which solution is the heaviest. Add the colors in rainbow order to impress the kids.
