It took a lot of oil, though. You can try other liquids, if you want to! When i added the tablet piece it sank to the bottom, dissolving and creating a gas. The alka-seltzer reacts with the water to produce carbon dioxide gas bubbles. You can change an independent variable so that means you can change the color of food coloring you use to make the experiment. This is because water is more dense than oil.
By: Eve Campbell Lava Lamp Science Fair Experiment Hypothesis: My hypothesis is that if i mix oil and water, then it will make bubbles from the gas at the top. Or, at least Henry thought so. We learned about mixing colors in the , it was a blast! If water acted like most other liquids, lakes and rivers would freeze solid and all life in them would die. Then, we let the bottle sit for a little bit and after we let it sit for a while we shook it and it worked out perfectly! Plus you need to be able to fully document what you have done and the conclusions that can reasonably be reached by your experiments. The lava lamp contains two substances which are a very closely guarded secret by the makers of lava lamps.
Dunnett Walker later discovered had died. State Your Hypothesis Question:Why doesn't oil mix with water? Anything but a volcano, they're too cliche. Total Time: 5-10 minutes Safety Concerns: None. This is Lava Lamp, Deluxe Edition. Once in the water the salt dissolves, releasing the oil to return to the top layer again.
A hypthesis is an educated guess on what is going to happen in your experiment. Go ahead and add an inch of oil on top of the water. Dependent Variable: We will measure the oil. It consists of two parts. Are you ready to make your own deluxe lava lamp using the brilliance of chemistry and some easy-to-find household materials? Hypothesis: If we combine oil and water we think the chemicals will form little blobs. We claim this because when we tried this experiment both times, the result was the same.
In fact, she had entire! It is meant for possible ingestion so if accidentally swallowed or comes in contact with little mouths. This is because water molecules are packed more tightly and a cup of water actually has more mass than a cup of oil. Oil is nonpolar while water is polar, which means they will never mix, even when shaken extremely hard. What if you drop a whole tablet in? Walker became determined to make a better version of the novelty item and spent the next decade and a half doing so inbetween running an international house-swap agency and making films about nudism. Where the oil and water connect and form bubbles! Not only do lava lamps contain a lot of different science properties, but they are really fun to have around the house also! Step 3 — Add food coloring! Then, when we put the food coloring in, we saw it break through the oil. Then we will transform the density tube into a beautiful lava lamp that is sure to delight even the oldest Science Kiddos.
Science Fair Project: Homemade Lava Lamp The basic knowledge of water and oil is that they just do not mix. Even though the amount of liquid is the same, the denser ones will be heavier. Can you explain how they each work? These stick to the water droplets. Walker worked on improving the lamp with his company the Crestworth Company of Dorset, England. It's your project, so you decide what you do with it.
The wax then becomes more dense than the surrounding liquid, causing it to sink, and the cycle starts over again. Because the oil is less dense than water so it floats to the top. Projects that are complex and based on energy are good, and fun to do. It all starts in the preparation. You don't want to have the coolest project ever and be beaten by someone who did loads more research and documentation. Which one do you think works the best? They won't let you down, no matter what they're up against. There are many different things that affect density, such as temperature.
We explored this question when we did our experiment. And it's a good thing it does! Does it mix with the oil and water the same way? Notice how the oil does not absorb the food coloring. It also shows me how much fun it can be. When we put the alka seltzer in we watched our lava lamp go before our eyes. Also it helped me see how you can make it look cooler.
Add food coloring, if desired. Or maybe because it was the tallest and skinniest, so it had the best reactions. Lava Lamp Science Experiment Discussion Points 1. If you have a bunch of wires and stuff, then you should partially conceal them, but not fully hide them. You can find it in pharmacy sections of stores where the laxatives are found. Step 4 — Add 2 Alka Seltzers in per bottle. The food coloring falls through the oil and mixes with the water at the bottom.
