PRE-LAB REPORT Lab: Density of Liquids and Solids Purpose of the experiment: The purpose of this lab is to help understand how to resolve the density of liquids and solids. Also‚ the lab is supposed to teach us how to record lab data and how to measure volume and mass the correct way. Lastly‚ it’s designed to help us understand significant values and its relationship to measurements and data recording. Lab Techniques: One technique that will be used during this lab is comparing the

Investigation: How does the number of maggots in the mass affect the temperature of maggot mass and development of maggots in the mass? Abstract The aim of this investigation is to find a correlation between the number of maggots in the mass and the temperature of maggot mass. To find the correlation the different number of maggots in each mass was placed in (the isolated by glass beakers) polystyrene cups. The internal temperature of masses was obtained regularly every 10 minutes during 30

sculpture actually existed in three dimensional spaces. We made sure to cover and define the difference between mass and weight‚ wherein mass is the amount of space something occupies where gravity is the objects mass in relation to weight. Then we started to go over the more technical aspects of the art are space and mass. The amount of mass the object has in relation to space and how the mass moves through space. Other areas to look at are the surface‚ the material‚ the volume or medium and of course

Data Analysis The pH of a liquid affects the brownness of a banana. This experiment was started by the question‚”Does the pH of a liquid affect the browning time of a banana? “ The hypothesis was “that the lower the pH the less brown a banana will turn.”. The experimental group was bananas placed in liquids with varying pH levels : lemon juice‚ lime juice‚ vinegar‚ baking soda water‚ alkaline water‚ and distilled water. This experiment’s dependent variable is the number of spots each banana has
