Plant Mitosis Virtual Lab
The purpose of this virtual lab was to find out each phase that produces the most daughter cells. The procedure was to count how many different daughter cells were in each different stage of meiosis. Joe and I's results support our original hypothesis. We had initially thought that Prophase would have the most daughter cells.
Hot Potato Lab-Inquiry
By: Joseph Rinaldi and Sean O’Donnell
2. Heat both potatoes in the microwave for 10 minuets.
3. Remove from heat and take initial temperatures.
4.Take the temperatures of each potato each minute for 15 minuets.
Conclusion: The purpose of this experiment was to discover if there was a correlation between service area and retaining heat. We set up a controlled experiment where we heated two potatoes, one small potato and one large potato. After we heated them up we took her temperature then every minute for 15 minutes we recorded the temperature. Our results from our experiment showed that the smaller potato lost heat quicker. These results refuted our hypothesis because we initially said that the larger potato would not retain heat as long as the smaller one. Our experiment had sources of errors which included a slight movement of the thermometer they change the temperature.

Strawberry Lab Report Conclusion
The purpose of this experiment was to be able to extract DNA from a strawberry. We set up a controlled experiment where we mashed up the strawberry and put it through a coffee strainer to try and isolate the DNA. Our results from our experiment showed us that the chemical characteristics and physical were completely different. These results support our hypothesis because we had thought that it would not be difficult to extract the DNA. Our experiment had sources of error which include being confused on which steps we had to start our experiment.
