12th Grade Biology Bridge Projects
Students who do not pass the High School Assessment in Biology must complete bridge projects in order to graduate. These projects require the students to carry out the scientific method with minimal guidance by their bridge instructor. They steps they have to complete are as follows: read a scenario, come up with a scientific question, complete background research, create a hypothesis, design an experiment, carry out the experiment, collect and analyze data, and come up with a conclusion. The seniors create their own projects. Several projects have focused on the impact that humans have on the environment. The project for 2011-2012 was the impact of detergent when used to clean bird feathers covered in oil. The projects for 2012-20313 focused on the effects of detergent on plant growth, the impact of acid rain on germination, and how clarity of water impacts the rate of photosynthesis.
The effect of soap on feathers- Completed March 2012
Tanika was a student that always struggled with Science. By being able to conduct the bridge projects, Tanika was able to graduate on time. She was very proud of her work she conducted on her own. She conducted research to determine what detergents are best used to clean off oil from birds. She learned about how soap is used to wash off the oil from birds who were affected by the BP oil spill. Based on this, she designed her experiment. She then recorded the weight of each feather before saturating each feather with oil. Then she took different types of soap and washed each feather in the soap solution for a specific period of time. Tanika then used a blow dryer to dry the feathers. She then recorded the weight of each feather. She created a data table and a graph to show the results of her experiment. Tanika took this information to describe which soap was most effective. She then related her experiment to the BP oil spill and what happens to organisms when our human endeavors go too far.
