Say you're hosting a birthday party and the birthday girl's cake needs to be lit up, but you've just run out of matches. What to do? While you can certainly go to the store and purchase more, doing so would take at least half an hour (an eternity to wait for little kids), it's probably easier to make a flame with what you've got at home.
Everyone floats in the Dead Sea because the amount of salt in water effects the density. Do a hands-on experiment and practice checking density. Here’s a good science experiment to do in class or at home, if you have access to an electronic balance.
In this Education video tutorial you will learn how to do a yeast experiment to see how much C02 it produces with different types of food. Yeast is a fungus and it has to eat. After it eats, it produces CO2 gas. The bubbles in bread are produced by the CO2 gas from the yeast. Take five different types of food items and measure out the same quantity for each item. In the video it is 8gms of cookie, oil, flour, salt and sugar. Take six glasses of water and mix one packet of yeast in each glass....
It's a stormy winter night, and you're electricity goes out. You could grab some candles to add a little light to your life, or you could use glow-in-the-dark chemicals for a cool luminescent.
This is how to make a near professional grade lava lamp. We did this as a chemistry project. We perfected it in a week. This took many hours to do, as we had to get the density just right. We remade it three times, also. At the very end, we combined all of the wax into a huge flask. And then it blew up.
Got an upset stomach or a little heartburn? America's favorite pink pill will cure it right up. But did you know that there's actually metal hiding in those chewable Pepto-Bismol tablets? Yes, metal. Technically, it's a poor metal, but metal's metal, right? Well, we do tend to eat a lot of iron in our diets, because it carries oxygen throughout our bodies, so consuming metallic minerals isn't anything abnormal. But you'd never think that Pepto-Bismol is actually made up of metal.
Mr. O shows his audience in this video how to make oobleck, a slime-like substance which has a variety of unique properties. For this project, you will need a mixing bowl, food coloring, corn starch, a measuring cup, and water.

Add some water to the bowl and add the cornstarch, then add the rest of the water. Finall...
Ever wonder why Jupiter has those colored bands across its surface? Jupiter's enormous mass is made from an array of different liquids, and those fluids do not play well together because of their different makeup. All of the hydrogen- and helium-based fluids are thought not to be miscible, which means that they aren't homogeneous in nature, resulting in strikingly beautiful bands across the planet's surface. But what about viscosity and how that correlates to the development of planets? What ...

In this tutorial, we learn how to make hydrochloric acid from salt. First, you will pour some salt into a distil flask. After this, you will add in some concentrated sulfuric acid to the salt. Next, you will let these react with each other. You will start to see gasses bubble up and the excess hydrogen chloride gas come out through the top of the tube. To create a stronger reaction, you can add heat underneath the reaction. Then, test this by exposing it to ammonium chloride. If it's the righ...
A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.
