What does the lava lamp experiment teach?

Changes in density as gas is added to or taken away from water cause it to float up and sink down through the oil. Thus the lava lamp is created! This activity is simple and provides a great demonstration for kids. This experiment allows the kids to see what is happening as you explain what and how it is occurring.

How do you explain a lava lamp to a child?

The Alka Seltzer reacts with the water to make bubbles of carbon dioxide. The bubbles attach themselves to the blobs of colored water and bring them to the top of the glass. When the bubbles pop the blobs of colored water fall back to the bottom of the glass. This lava science experiment is sure to WOW your kids.

Why does the lava lamp experiment work?

How it Works: The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve.

How do you make a lava lamp out of dish soap?

Start with a clear vase or jar pour in one layer at a time: 1. First, mix 4-5 drops of purple food coloring into corn syrup, then pour into jar. 2. Next, carefully pour in Dawn dish soap – it should already be blue!

What is the dependent variable in a lava lamp experiment?

INDEPENDENT VARIABLE- The temperature of the water. DEPENDENT VARIABLE- We are measuring how well the lava lamp works. CONSTANTS- The amount of water, oil, and salt put in the the container will be about the same.

What is inside a lava lamp?

What type of mixture is a lava lamp?

What liquids are used in lava lamps?

The whirling globs we remember are made mainly of paraffin wax, with compounds like carbon tetrachloride added to increase its density. The liquid the wax floats in can be water or mineral oil, with dyes and sparkles added for whimsy.

How can we make lava at home?

STEP1 – Fill your glass just over half full with water and add a good few drops of food colouring. STEP2 – Pour just less than 1 quarter cup of vegetable oil into the cup. It will soon settle out to form a layer on top! STEP3 – Sprinkle a good dollop of salt on into your cup to start making your lava!

How to make a homemade lava lamp?

How to Make the Lava Lamp. Break open an oil-soluble marker or pen and place the inked felt into a container of benzyl alcohol. Leaving it in longer will give a darker color, but will also increase the tendency to bleed into the brine. A few minutes is usually a good time to leave the inked felt in the alcohol.

What is the science behind a lava lamp?

Water&Vegetable Oil. First you are going to fill the bottle about 2 quarters full of vegetable oil.

Food Coloring. Then you add your food coloring to the mixture.

Alka Seltzer. Go and break up the alka seltzer into four small pieces,and add them into the lava lamp 1 at a time.

ERUPTION!!! Now your lava lamp should start springing into acton.

The Lesson.
