Did the raisins and other objects sink and float when you expected them to? Homemade Lava lamps are a fun activity demonstrating that oil and water dont mix. Density is how much mass is contained in a volume of measurement (D=M/V). Density is an abstract concept for young students. Once we had our supplies gathered we followed these instructions to do our salt water experiment: *Hint: You may need to add more salt/sugar/baking soda to the water, depending on what kind of jewels or food you are using in this experiment. Allow your children to speculate on where they believe the objects will land. Therefore, one can sit on top of the other the more dense a liquid is the heavier it is. An object whose density is greater than that of the liquid will sink in it. This is primarily because the volume and mass of a liquid can be directly and simultaneously measured. The dropper/pipette should work well for the stacking two liquids part. Sometimes students wrongly think that an object's density is the same as its weight or its mass. The next dense will float on top of that, and the least dense will float at the very top. The adult involved is fully responsible for ensuring that the activities are carried out safely. And why do some liquids mix together easily (think lemon juice and water for some tasty lemonade), when others don't mix together at all? And to make this even more fun, lets use flavored sugar water. Which is denser, sugar water or saltwater? (The thing you dont change so you can compare other things to it.) Kids will love making and observing the liquids in the rainbow density jar. These hands-on activities can help kids. We watched Ocean Deep and Shallow Seas to go along with this ocean science experiment. Give it a try. I just found that resource. Stir each of the cups to make solutions of different densities. If you measure the mass of different liquids, the liquid with a greater mass for the same volume will be denser. {Pay attention to the amount of sugar in each juice. Im new to teaching and I am looking for low budget ideas for middle school physical and life sciences. (This part may take a little practiceif you add the red water too fast you will force the colors to mix. Write down what you think will happen when you mix cold water and hot water. It could be any form of a container, provided it has the markings that facilitate volume measurement. Different liquids, solids, and gases will have different densities. Submarines are built with special tanks called ballast tanks. However, it is different in the form that it changes the liquids ability to sink or float the object. 2. Our science . Density is the measurement of how closely molecules are packed together in a given material (in this case, liquids). Release the drops of juice as close to the surface of the second juice as possible. When the sub reaches the correct depth, its density is adjusted by changing the amount of air or water in secondary tanks called trim tanks. 2. Enjoy!

This test helps you see the higher density of seawater, but a real sub doesn't have to add fresh water to the ballast tanks - it just fills up with the higher density salt water. Try it out with a plastic drink bottle in the sink or bathtub. The denser a liquid is, the easier it is for an object to float on it. Required fields are marked *. Plus, our supplies lists usually contain only free or cheap materials you . What is the difference between mass and weight? If you fill the bottle with water, its density will increase and it will sink. At a lot of times, these containers are accompanied by a scale that can measure the mass of the liquid. On the other hand, an object which is less dense than the liquid tends to float in it. PS thanks for sharing on Kids Get Crafty! Density is a measure of how much mass is contained in a volume (density = mass divided by volume). Did it stay in layers? Once they are done with this, perform the activity and check out the students having the most number of correct answers. Encourage your kids to make predictions, discuss observations, and re-test their ideas if they dont get the desired results the first time. I'm completely fascinated by density, and my kids and students have also always been equally excited about learning about how liquids can stay separated based on their density. Each of the liquids has a different mass of molecules or different numbers of parts squashed into the same volume of liquid; this makes them have different densities. It was absolutely FASCINATING to watch that process! Thanks for this idea. Add a handful of ice to the blue water and put it in the refrigerator for a few minutes. Owing to this, they are often confused with one another. I love love love this idea! Relative density, once calculated, can be interpreted in three different ways. Layer the liquids in the large container in the following order: Molasses, water, vegetable oil. In such cases, density measurements are extensively used. As soon as the sub's density is more than the water's, the sub will sink. (Using a syringe or medicine dropper makes it easier. Place equal drops of food dye into each cup of water - place blue into one cup, red into another, and yellow into the final cup. STEP 1: Set out 6 glasses. - Easy Density Experiments and Tricks for Kids Wonderful Women in STEM Home Science Experiments for Kids Chemistry What is Density? When the relative density is lesser than 1 If the relative density is lesser than 1, it indicates that the substance is less dense than the reference substance.

The salt water and baking soda water should make the jewels float. We tried with different coloured salt solutions, but it didnt work as well as yours. People often talk about weight when they mean mass and vice versa. Liquids have density, too. It is measured in cubic units, such as cubic centimeters (cm3) and cubic meters (m3). If you want to find out the approximate density of each, you can calculate it using this formula: Density = Mass/Volume. In the ocean liquid density experiment, kids can learn how the different densities of water separate the layers of the ocean. Ask students to record the number of teaspoons of salt that made the egg float. Density refers to the amount of stuff there is in a given space. Look at this playful and colorful way for younger kids to explore oil and water, along with the concept of density. Many objects that sink in fresh water will float in salt water! Can you find an object to float on each layer. What you need is a fish tank full of water, a diet coke, and a regular coke. Layering Liquids Density Experiment We have done this density experiment before with our saltwater density investigation. If the juice goes too fast, it tends to mix. If the juice sinks to the bottom, then it is more dense. All with easy household supplies! See me at Pinterest. The ocean liquid density experiment isnt difficult to do, which makes it a perfect simple science fair project for kids in early elementary school. Because these liquids will have different densities, there will be a density tower, or different layers, that are visible, sort of like being able to see ice cubes (frozen water) in room temperature water. For additional research for older kids, have them find out what types of animals live in each ocean layer and what specific biological functions they use to prevent from being compressed by the dense water in the deeper ocean layers.

You can find most of these liquids in your own home making this a simple kitchen science project for kids. Which is the densest: water, corn syrup, or vegetable oil? Apparently, yes they do. The Navy has to keep track of the salinity of seawater (how much salt is in it) because salt makes the water denser. Pour water in both glasses but add salt just in one. When the relative density is greater than 1 If the relative density is greater than 1, it indicates that the density of the substance is greater than the reference. You can use this as an easy way to compare the density of a liquid to a solid. In the realm of Physics, there are several properties used to define or describe matter. To measure the density, you will require a volume-measuring container. I showed Aiden the different liquids and told him they each contain a different amount of sugar. Here is a list of nine simple science experiments that deal with density of various objects and liquids. It's cold and dark. You can check out the entire density rainbow activity here. Megan from Coffee Cups and Crayonsasks: Does it dissolve? But what about liquids? Will a raisin, paperclip, penny, small cork, ball of paper, and other small objects sink or float if they are placed in water, corn syrup (or light corn syrup), and vegetable oil? several small objects - raisins, paperclips, pennies, small corks, etc. This post was originally published on August 7, 2013.

Density Experiments for Kids Updated April 24, 2017 By Pauline Lovingood Density is an abstract concept for young students. Add the liquids to the jar in reverse order (purple, blue, green, yellow, orange, red). Instead of using saltwater, we are using sugar water. Check out our layers of the ocean activity. Will adding sugar make the water denser? In simple terms, density is a property of measurement that determines the amount of space which is taken up an object or a substance. Measuring the density of a liquid is easier than measuring the density of a solid. These include: 1. Which layer was on the bottom? weight and weight distribution are highly important. The syringe will help it go slowly. (Your answer will be more exact if you use a graduated cylinder instead of a beaker to measure the volume and weigh the liquid.). Check out our to see what we did. Flip a Rainbow Light Refraction Experiment. On the other hand, density lets you know how compact an object is. This density experiment is very neat. Experiment with adding sugar to water to see if it increases the density of water. Once you fill the aquarium with a liquid, you can ask your students whether a particular ball will sink or swim. It varies in depth but often contains a lot of marine life. Wouldnt it be fun to stumble across a gold nugget in the ground, because even a small amount of gold is worth a lot! Density and buoyancy are closely related In the floating and sinking of objects section, we discussed that denser objects sink in less dense liquids and vice-versa. Use common items such as water, eggs, oil and salt to demonstrate density. Discuss what liquid the children think might be the most and least dense liquids and objects and record their predictions.
