Injecting yellow perch with an egg ripening hormone in order to encourage spawning
Testing water quality parameters in the Tuckahoe River where quality yellow perch eggs have been found
Conclusion: A general trend can be seen, however trials have not been completed, therefore no definite conclusions can be made.
“The effect of abiotic factors on hatching and mortality rates of Artemia”
Grade Level 6-8
Major Emphasis: Biology, Microbiology, Environmental Science
Major Curriculum Area: Science
Related Curriculum Area: Math
St. Marys of the Mills
How do abiotic factors such as pH, temperature, light, salinity, and contaminants effect the hatching rate and mortality of aquatic organisms?
Students will design their own experiment and form their own hypothesis based on previously presented material. An example might be, “Artemia will hatch more quickly when more salt is added to the water.”
An Approach to Enhance Scientific Investigation in the Classroom
Engagement: Grab the students' attention and stimulate their thinking
Exploration: Students think, plan, investigate, and organize collected information
Explanation:Students analyze their exploration
Extension: Students expand and solidify their understanding of the concept & apply it to real world situations
Evaluation:Scoring tools developed by the teacher and students to target what students must know
Students think, plan, investigate, and organize collected information
“THINK, PAIR, SHARE”
THINK-Students will brainstorm on their own several problems they would like to investigate and ways to design an experiment in order to test their problem. (Suggested topics may be: the effect of: pH, temperature, light, salinity, fertilizer, oil, eroded soil, on the rate of hatch or on live Artemia.)
PAIR- Students will discuss their ideas with other students at their lab table and decide on a problem, hypothesis and an experimental design.
SHARE - Lab table groups will share their work with the class. Class will offer compliments and constructive criticism/ suggestions for improvement of project designs.
