This experiment involves placing bird feeders with a specified amount of bird seed in different locations around the school grounds to determine if human presence has an impact. After a designated period of time the bird seed is weighed to determine what location attracted the most birds. Data is collected and then submitted to be posted online. By using an already tested scientific research method, students can determine the numbers of a mobile population of insects. Grasshoppers are captured, marked, and then recaptured.
Students learn how to use an algebraic formula to determine their populations.
The purpose of this experiment is to determine the types of pigments found in schoolyard vegetation. The students will gather plants from the schoolyard, soak them in acetone and use coffee filter strips to separate the pigments. Then the students will determine the pigments found in each type of leaf. This experiment is an excellent way for your students to investigate solar energy. With our sources of energy being depleated we must look to other forms of energy.
