Title: Density impacted by Acids

Problem: Does an Acid impacted the Density of vegetables?

Hypothesis: If you boil mixed vegetables in the acid vinegar, then the density of the mixed vegetables will decrease because of the chemical change that happens with the vegetables.

Materials list: mix vegetables(carrots, green beans, peas, corn), water, apple juice, milk, vinegar, small pot, the stove, containers, the fridge, balance( to measure the mass of the vegetables), beaker and gas.

Procedure: 1)Get the listed materials that are above and sort them based on weather they are used in the project. 2) Measure the amount of mass on the balance beam for each vegetable. (Note: The mass has to be close to the first mass you measure and the mass can not go over of 1 grams) 3) Measure the volume of the mixed vegetables by putting water in the beaker and then the vegetables to see how much volume is in the vegetables. Then divide the mass over the volume to get the density and record them in the lab table.(Note each volume will be different depending on the amount of corn, carrots, peas, and green beans that are in each trial) 4) Measure out the liquids (water, vinegar, apple juice and milk) to a 1/4 of a cup for each liquid. 5) In the pot, put the 1/4 of the cup of water in the small pot with the vegetable. When water comes to a boil remove the vegetables, by draining, the measure the mass and volume of the vegetables. Then the divide the mass by the volume to get density and record that in the data table. 6) Repeat step 5 seven times to get seven trials for that liquid. 7) Repeat steps 5 and 6 for each liquid. 8) After measure the density after boiling, put each trial, labeling each trial, in the fridge and leave them there over night. 9) Measure the mass and volume for each trial after the over night in the fridge. Then divide the mass by the volume to get density and record the density of the vegetables in the data table.
