Smartie Lab Analysis: The total area of my ecosystem was six feet‚ but the area we sampled was four feet. We had six types of each smartie: 4 green‚ 5 orange‚ 10 purple‚ 7 red‚ 5 white‚ and 14 yellow. In our sampled area we had 3 green‚ 0 orange‚ 5 purple‚ 2 red‚ 0 white‚ and 7 yellow. We had 4.25 organisms per total area that was the density. Our relative density was 8.88% green‚ 11.11% orange‚ 22.22% purple‚ 15.55% red‚ 11.11% white‚ and 3.45% yellow. The frequency of each organism was 75% green

important step to start the research project is finding a research problem and there are many important steps that can be taken to turn a question into a research problem that readers think is worth of solving. There are two types of problem‚ Practical and research problem. Practical problems lead to research problems‚ and the answers are planned to help solve the practical problem. Practical problem are significant therefore it should not be ignored because ignoring it can lead to trouble. Practical
