Comparing the Density of Metals Question: What is the effect of changing the type of metal on its density? Hypothesis: If a different metal type is used‚ then the density will change. Materials: 4 metal samples Balance 50 ml graduated cylinder Water Paper towels Apparatus: Pre-Lab Questions: 1. What’s the formula to calculate density? D = M / V

relative intensities of light at various horizontal distances from the lamp. The light detector (photocell) will enable us to make light intensity measurements that are more precise than those made with the human eye. The photocell converts light intensity to an electrical potential difference‚ which can be measured with a voltmeter. Using our measurements made from numerous elevations above the table‚ we assumed voltmeters were proportional to the intensity of light and observed a relationship between

ordinary chemical reactions or physical changes‚ which means that no matter how dramatic of a change that a substance goes through‚ it will not lose mass. It may seem like it lost mass‚ and usually‚ if you weighed the result‚ it will have a different measurement than when you first started. Sometimes the mass is lost into the atmosphere. Procedure: Part 1: 1. Acquire‚ label‚ and record the weight of two beakers. Weigh 2-3 (g) of baking soda with one beaker. 2. Measure approximately 50 ml of vinegar

If a plastic sandwich bag is tied around a Magnolia tree‚ a Ligustrum tree‚ and a Robellini palm tree‚ which tree will transpire the most? This project relates to the outside world because someone could get lost in the woods and need water‚ so they need to know which tree will be the most efficient. The original hypothesis was‚ if a plastic sandwich bag is tied around a Magnolia tree‚ a Ligustrum tree‚ and a Robellini palm tree‚ then the Magnolia tree will transpire the most because it has the largest
