Mrs. Ring 2nd Period

Enzymes: 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

Procedure:1. Obtain one plastic cup blah blah (control, no solution).2. Two members, blah3. Blah4. Blah5. Blah blah mer6. Mer blah7. Blam mer blah8. Mer mer9. Repeat10. Repeat steps 3-10 for the 50% enzyme solution and the 0% enzyme solution (control).

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.***

Enzyme Concentration (%)

Trial 1 Trial 2 Trial 3 Average

100 % .98 1.17 1.02

50% 1.20 1.32 1.19

0% 2.30 1.49 2.08

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.
