How well does one biodegradable or compostable material decompose compared to another? In this science project, you will explore this question by making your own indoor composter. You will need a basic understanding of "brown" and "green" scraps, small pieces of organic matter that you add to a compost bin to create compost.
Identify scientific (testable) and non-scientific (non-testable) questions. Ask questions that can be investigated and predict reasonable outcomes based on patterns such as cause and effect relationships.
Key Info. Background research is necessary so that you know how to design and understand your experiment. To make a background research plan — a roadmap of the research questions you need to answer — follow these steps: Identify the keywords in the question for your science fair project. Brainstorm additional keywords and concepts.
Science fair projects are based on the scientific method. Students formulate a hypothesis and predict the outcome before performing the experiment. The test results support or refute the hypothesis.
20 mar 2014 · With Earth Day and Science Fairs on the horizon, there are many great themes to help students examine an environmental topic in depth and educate their classmates and parents at the same time. Here are some ideas for environmental science fair projects:
Use historical data and current conditions to find out how the number of sunspots affects Earth’s weather. Can this information be used to accurately predict weather patterns on the earth? Use a radio to measure changes in the ionosphere.
In the video for Session 8, Dr. Adrien Finzi walks us through a deciduous forest ecosystem and identifies some of the elements that compose living — or organic — matter. These elements include carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P), sulfur (S), calcium (Ca) and iron (Fe).
