Biology Lab Reports

This lab report investigates how enzyme concentration affects the reaction time of enzyme activity in hydrogen peroxide solutions. The hypothesis posited that increasing enzyme concentration would decrease the time taken for a paper disc to rise to the surface. Materials included various enzyme solutions and procedural steps were followed meticulously to ensure accurate results. Data was collected and presented in both paragraph form and graphical representation. The analysis revealed whether the hypothesis was supported and discussed potential errors for improved future experiments.

  1. Biology Lab Reports

  2. General Formatting • 12 Point Font Size • Times New Roman Font • One Inch (1”) Margins • Header including Name and Class Period on EVERY PAGE

  3. Mrs. Ring 2nd PeriodEnzymes: How Fast Can They Go? This is what the top of your paper should look like. If it looks similar to this you will automatically get four points! I know it is not listed on your Rubric but please insert a header with your name and class period on it so I know who to give credit to.

  4. Mrs. Ring 2nd PeriodEnzymes: How Fast Can They Go? Problem: How does enzyme concentration affect the reaction time of enzyme activity? Hypothesis: If the enzyme concentration increases, then the time it takes for the disc to rise to the surface of the hydrogen peroxide will decrease, because________. Materials: • Beaker with H2O2 Timer • Forceps 0% enzyme solution • 3 cups 50% enzyme solution • Filter paper discs 100% enzyme solution • Paper Towels

  5. Procedure: • Obtain one plastic cup blah blah (control, no solution). • Two members, blah • Blah • Blah • Blah blahmer • Mer blah • Blammer blah • Mermer • Repeat • Repeat steps 3-10 for the 50% enzyme solution and the 0% enzyme solution (control).

  6. Data: You must summarize your data in paragraph form AND in table and graph form. EX: The data shows ***If you do not know how to insert tables or graphs please ask a friend or you Computer teacher and they can assist you with this.***

  7. Analysis/Conclusion: My hypothesis was supported/unsupported(pick one that matches your data) because the data shows…. The independent variable (concentration) caused_____________..... The ___% solution was the fastest by_____. Some possible errors that could have occurred during our lab were_________. Had we done _________instead, we could have had ____________ results.
