A geologist and a biologist performed an experiment together and examined the data. Each scientist formed a different conclusion. Both conclusions were supported by the evidence. How is this possible?
Why are graphs useful when interpreting data?
Gerald performed an experiment to determine if photosynthesis was affected by the color of light that a plant received. The data from his experiment are shown in the table below.Color of LightNumber of plantsAverage volume of oxygen produced (mL)green40.50orange42.0blue45.0Which format should he use to present his data?
Francis was recording plant heights for an experiment. Each time that she took a measurement, she wrote it down. Then, she measured the plant again and compared the new measurement to the one that she had recorded in her notebook. What was she most likely trying to do?
What is the most appropriate way to present the data below?Week Plant Mass (g)1222613874123
Denise was measuring the effect of temperature on the amount of dissolved oxygen that water can hold. She hypothesized that as water temperature increases, the amount of oxygen that is dissolved in water increases. Her data are shown in the table below.Water temperature (ºC)Dissolved oxygen (mg/L)512.51011.01510.2209.1258.3Which conclusion did Denise most likely write in her lab report?
How can evidence from an experiment be explained in relationship to the hypothesis?
A good conclusion restates the hypothesis so that the reader
For a conclusion to be accepted by the scientific community, the data must be accurate, free from error, and
Maria wanted to learn more about the birds that visit her backyard. She installed several bird feeders and offered a variety of bird seed mixes in order to attract a mix of species. For a month, she observed the bird feeders three times a day for an hour each day and counted the types of birds that she saw. Then, she made a pie chart to represent her findings. What is the most likely reason that she chose a pie chart?
