Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

- Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount of water in the balloon. 2. Inflate the yellow colored balloon and tie it up. 3. Pour half a cup of water into the blue colored

Chemistry plays an important part in studying Biology. It answers some questions that Biology could not explain alone. Questions like: How does an organism convert foods for energy? How do plants use sunlight and water into all the things that cells needed to grow and reproduce? How does the basic unit of life passed through generation to the next? Here are some contributions of Chemistry in Biology: • Within atomic theory‚ chemistry contributes towards biology in the understanding of atoms and elements
