Lab Report: Soaring Staws

Soaring Straws

  In this lab, we had to figure out how the gravitational potential energy of a straw rocket depending on the elastic potential energy of the rubber band launcher. The relationship of the G.P.E (gravitational potential energy) and the E.P.E. (elastic potential energy) is the more the straw stretches, the E.P.E increases which means the straw will go higher than usual. Also, the amount of stretch is the manipulated variable and the responding variable is the height of the trials, which means the amount of stretch is related to the E.P.E. (elastic potential energy). When the rocket takes off it has K.E. (kinetic energy), and the G.P.E and the E.P.E. are now converted to kinetic energy.

            The possible errors that might have occurred are the data could have been typed in the calculator incorrectly. Also, the amount of stretch could have been miscalculated. Another possibility is that the data for the plot could be incorrect.

Toothpick Fish

In this lab, in completed recently I experimented with genes, alleles, phenotype, genotype, and the environment with toothpick fish. There are four different fish with different alleles. There are green, red, yellow, and orange. Green is dominant, red and yellow are recessive and orange is incomplete dominance (red and yellow make orange).  In this lab, I had to make four different generations, to do that I had to pick randomly from a cup and add up the offspring. If two yellows were paired they would be eaten immediately, and go into the morgue. The generation next would have one less box because the yellow allele/fish is in the morgue.
        The first generation has eight green fish, one red fish, zero yellow fish, and two orange fish. The second generation has seven green fish, one red fish, one yellow fish, and two orange fish. The third generation has six green fish, one red fish, zero yellow fish, and four orange fish. The fourth generation has seven green fish, one red fish, zero yellow fish, and two orange fish. Now, there is a natural disaster, all the rocks and sand are now exposed and are good camouflage for the red ,yellow, and orange fish but not the green, all the green are eaten. The only survivors are one red fish, and two orange fish.

A Camouflaged Creature

There is a camouflaged creature somewhere in my environment. I can’t seem to find one because it’s camouflaged from its predator and prey. They are hiding form there predator because the want to stay alive and they hide from their prey because they would like to sneak up on them. The reason I can’t find it is because to it I’m its predator, then who is the prey. We’ll never know because we don’t know the creature.

Biotic Limiting Factor across the street

There is a suspicious limiting factor across the street in the big field. I’m wondering if the animal or animals are living under the barn. I have come to a conclusion, there is a groundhog living under the barn in the field and it’s limiting the population of squirrels. The male or female groundhog only comes out on mid temperature days. In Conclusion, the world will never know is the suspicious groundhog going to attack again and is it male or female?
