Once your sugar is dissolved, start by adding the most dense solution to the bottom of your tall glass. Repeat the process until the sugar is dissolved. Place the cup of water in the microwave and heat for 10-20 seconds. If the sugar doesn’t dissolve, the solution is over saturated and you must supersaturate it by heating the water. Mix the sugar into the water until it is completely dissolved.
Label each cup with the amount of sugar added. In the first cup, add 2 tablespoons of sugar, in the second add 4 tablespoons of sugar, third add 6 tablespoons of sugar and in the last add 8 tablespoons of sugar. Then color the water with either food coloring or Kool-Aid. The exact amount isn’t as important as each glass having the same amount of water. Start by filling each glass with about a cup of warm water. You will need 4 short glasses and one tall, clear glass, a dropper, sugar, water, measuring spoons, and food coloring or Kool-Aid. I’ll list the kitchen supplies, but if you are interested in the SSS supplies, visit the Sugar Water Density Tower experiment for a complete list and more of the science behind the activity. We used materials from Steve Spangler Science, because well you know why. Hence, the name Kitchen Science, but you knew that. Instead of using Kool-Aid, we used colored water, but either one will work.įor this experiment, everything you will need is found in your kitchen.
Time to take out the sugar and demonstrate what happens when you add 14 spoonfuls of sugar to one small cup of Kool-Aid. Do your children like to dump spoonfuls of sugar into their Kool-Aid or a giant scoop of Gatorade powder into a glass of water like mine do? This experiment teaches a lesson in density and supersaturated liquids. So instead of a rainy day activity, we hunkered down inside to stay out of the midday sun and 100 degree temperatures. Many areas are facing severe drought situations. This summer has been extremely hot and dry across the country. Usually around this time of the summer we are looking for indoor activities to do on a rainy summer day. Weather STEM Activities – Weather Science for Kidsįor this week’s Sick Science!

When you mix two or more substances, the most dense substance sinks to the bottom, whilst the least dense substance is more buoyant and floats to the top. This is why you should never comment on your Auntie Mabel's sponge cake by describing it as dense: she was probably going for something a little more airy.ĭensity is also what makes things float or sink. A pound of feathers is filled with airy space, so it's not very dense at all, while a pound of lead feels much more solid, so it's more dense. For an equal amount of space it takes up (volume), lead weighs much more than the feathers (mass).ĭensity can also be thought of as how compacted or compressed a substance is. So if the question was, 'Which weighs more: a 500ml jug full of feathers or a 500ml jug full of lead?' then the answer would be the lead. What is density?ĭensity is the mass per volume - not just the straight-up mass. Read on to find out exactly what density is, how it works, and how to calculate density. Although the feathers and the lead both weigh exactly the same (um, a pound), their density is wildly different, and we can sometimes mentally conflate weight and density - even though they're different concepts. If you've ever been fooled by the old question, ' Which weighs more: a pound of feathers or a pound of lead?' then you wouldn't be alone. To calculate density: p = m/V To calculate mass: m = pV To calculate volume: V = m/p
