Make a Lava Lamp Science Experiment

Even though the amount of liquid is the same, the denser ones will be heavier. A homemade lava lamp does not use heat at all. Use food coloring to make a rainbow of colors. To figure out where your new liquid would fit in the column, you can measure the density of all the liquids. You may have to wait a couple of minutes for the oil and water to separate. The piece of Alka-Seltzer tablet you drop in after releases small bubbles of carbon dioxide gas that rise to the top and take some of the colored water along for the ride. Water does the opposite: it expands as it freezes, lowering the density.

As it gets farther from the light, it cools down, becoming more dense again until it sinks; then the cycle starts all over. Position the flashlight under the lava lamp and watch how it glows. Looking for more fun and easy science experiments for kids? What happens when you add the Alka-Seltz er to the bottle? Next, put in 4-5 drops of into each bottle. Credits This activity is not appropriate for use as a science fair project. But Home Science Tools' products and service can handle it. This Video is full of facts about lava lamps.

Make an Alka

One exception is water - it becomes more dense with cold until the freezing point, but it freezes in a crystalline structure that makes ice less dense than liquid water. Use simple household items such as vegetable oil, food coloring, Alka-Seltzer and a bottle to create chemical reactions and funky balls of color that move around like a real lava lamp. Acid-base reaction — A chemical reaction between two substances where one is an acid and one is a base. The food coloring falls through the oil and mixes with the water at the bottom. Drop one piece into the bottle and watch the reaction that takes place.

What happens when you add water to the plastic bottle? You can see the same effect if you try - another of our favorite easy children's homeschool experiments. Fill the rest the way with water until about 2 inches from the top. Put in 4-5 drops of into each bottle. Since each new liquid was less dense than the one before it, it floated on top instead of mixing together. He used the entire box of Alka-Selzer just for this experiment! And if your science inquiry doesn't go as expected, you can expect our customer service team to help. Break your Alka Seltzer tablets into 4 pieces.

Enjoy our range of fun science experiments for kids that feature awesome hands-on projects and activities that help bring the exciting world of science to life. The seltzer tablets release carbon dioxide, which blends with the water and allows it to float in the oil. How much time a lava lamp takes to heat up? Oil and water mixture — Oil, a hydrophobic compound, and water, a hydrophilic compound, do not mix. In a real one, however, the densities of the liquids are much closer together than vegetable oil and water. After the tablets were all dissolved, and the bubbles calmed down, I added another tablet to the bottles and repeated the lava effect. How to make a lava lamp We love easy science experiments.

It was even interesting from the top of the bottles. It's nice to see that you are a 2nd generation homeschooler. How to Make Lava Lamp Bottles Start your experiment by filling each empty bottle about ¾ of the way full with. Adding things to a liquid will also change its density. How long will a lava lamp bulb last? As the reaction slows down, simply add more alka-seltzer. Whether it's over eager young scientists year after year, or rigorous requirements that come once-in-a lifetime. You may find it easier to use a pipet for this one instead of pouring.

This causes the separation we see in this experiment as well as in our kitchen sinks and oceanic oil spills. Fill the plastic bottle ¾ full with vegetable oil. The water will sink to the bottom under the oil. Tip the bottle back and forth and observe the reaction. Drop an into each bottle and watch all the bubbles start up and float all around like a lava lamp. See if you can make a lamp powered by heat! Density is affected by temperature—the hotter a liquid is, the less dense it will be. Phosphorescence is a slower process in which energy is absorbed and released as light, so once a phosphorescent material is charged with light, it may continue to glow for several seconds, minutes, or even hours, depending on the specific chemicals.

When the air comes out of the colored water blob, the water gets heavy again and sinks. You may want to use a measuring cup with a spout or a funnel. You can try other liquids, if you want to! What Happened: Each of the liquids you used had a different density. The creation of the lava lamp and the observations related to its operation give the student insight into the inner workings of a lava lamp and a creative science project to do at home or school. Break the seltzer tablet into several pieces. Oil molecules, however, are non-polar— they don't have a positive or negative charge, so they are not attracted to the water molecules at all. This homemade lava lamp was just as exciting As always, all activities seen on the Fun With Mama website should be done under close adult supervision.

The alka-seltzer reacts with the water to produce carbon dioxide gas bubbles. The water will sink to the bottom under the oil. How it Works: The oil floats on top of the water because it is less dense or lighter than water. You can even put a lid on your bottle for use another day! And it's a good thing it does! Henry dropped in tablet after tablet. See detailed discussion in Introduction section. Once we were starting to run out of Alka-Selzer tablets, we started combining the colors and making them bubble together. Even though the amount of liquid is the same, the denser ones will be heavier.
