based on the chart above identify the qualitative and quantitative observations, the dependent and independent variables, and the measuring and recording data and identifying possible sources of error prior to data collection

Help with this question please:

• Determine if the observation is qualitative or quantitative. •Write a hypothesis and a null hypothesis. • What would be yourexperimental approach? • What are the dependent and independentvariables? • What are your controls - both positive and negative? •How will you collect your data? • How will you present your data(e.g., chart, graph)? • How will you analyze your data?

You accidentally left a carton of milk on the counter all night,and you notice that the milk tastes worse than it usually does whenit is stored in the refrigerator.

design your own scientific experiment (you don’t need to carry it out). Your experiment should be in the field of biology. Identify the observation you made, the hypothesis you will be testing, the independent and dependent variables, and 3 control variables that should be used.
