Introduction The scientific method was used during this experiment to teach us how to use it properly. The steps that are included in the scientific method are listed as such observation, problem, hypothesis, experiment, theory, and lastly law. (Maris,2010) These three experiments were conducted to see how well we could measure, calculate math equations, use the scientific method, and collect data. Most of the information that we collected was known due to the fact that the data was all at random. My partner and I had to determine through experimentations what was inside the black box. Materials and Methods A. Measurements 1. A 10 inch long flexible ruler 2. Top loading balance 3. Petri dish B. Black boxes 1. 2 boxes 2. Top loading balance 3. Objects in both boxes C. Fish Respiration 1. Goldfish 2. Beaker 3. Aquarium water 4. Ice 5. Thermometer Table 1.0: Length and weight of Sea Urchins Individual Length (mm) Weight (g) 1 28 1.3 2 26 1.0 3 27 1.1

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
