Density tower

  1. 1. 6 Layer DENSITY TOWER By Caryl Vivien Capiral Gr 7 SJAT
  2. 2. Materials needed:  spoon  glass  funnel  syrup  milk  dish soap  water  cooking oil  rubbing alcohol  2 food colourings
  3. 3. Procedure: 1. First, pour an amount of syrup. 2. Second, pour the milk. 3. Then pour the dish soap. 4. Then add 2-3 drops of food colouring to the water. Then take a spoon and scoop up a little bit of violet water , take a funnel and slowly pour it against the side of the glass. 5. Next thing we’re going to add is the cooking oil. Again, slowly pour it into the glass. 6. For our last layer add 2-3 drops of food colouring to the rubbing alcohol and stir. Again, take a funnel and put against the side of your glass and pour it into the glass
  4. 4. If each ball has the same mass, which box would weigh more? Why? The box that has more balls has more mass. This property of mater is called density. The density of a material helps to distinguish it from other materials. Since mass is usually expressed in grams and volume in cubic centimeter, density is expressed in grams/ cubic centimeter.
  5. 5. How the Density tower works?  You made your column by pouring the heaviest liquid into the glass first, followed by the next- heaviest liquid, etc. The heaviest liquid has the most mass per unit volume or the highest density. Some of the liquids don't mix because they repel each other (oil and water). Other liquids resist mixing because they are thick or viscous. Eventually some of the liquids of your column will mix together.
  6. 6.  The same amount of two different liquids will have different weights because they have different masses. The liquids that weigh more (have a higher density) will sink below the liquids that weigh less (have a lower density).  Density is basically how much "stuff" is smashed into a particular area... or a comparison between an object's mass and volume. Remember the all- important equation: Density = Mass divided by Volume. Based on this equation, if the weight (or mass) of something increases but the volume stays the same, the density has to go up. Likewise, if the mass decreases but the volume stays the same, the density has to go down. Lighter liquids are less dense than heavy liquids and so float on top of the more dense layers.
