Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

Oreos have double the filling‚ then the filling will have a larger mass. Materials: 4 regular Oreos 4 DSO I scale 1 paper plate 1 napkin Procedure: 1. Weigh all the regular and DSO on the scale. 2. Record into the data. 3. Find the average of each type of Oreos. 4. Repeat step 2. 5. Scrape off all the filling with a fork. 6. Weigh two of the cookie wafers that have no filling. 7. Use the equation (1 cookie – 2 cookie wafers) for each Oreos to just get the filling. 8. Repeat step

Laboratory safety is an integral part of any lab experience. If the participants are unkempt or precarious‚ they can easily cause a huge accident or even tragedy. When working in the lab‚ so many different hazards are faced. The rules of the laboratory are in place to ensure that one does not hurt themselves‚ let alone everyone else in the room or even the whole building. Each person needs to be responsible for themselves‚ while also watching for potential dangers others may not notice. The first
