HOW TO USE SCIENTIFIC WORKPLACE 6 DRIVERS

The alternative hypothesis could be that there are a significant number of solo drivers using the carpool lane.

Construct Hypothesis: The null hypothesis might be that there are zero people driving alone who are using the carpool lane on the freeway.Define Purpose: I want to know if solo drivers are illegally using the carpool lane on the freeway in my city, and if so, how widespread the problem is.Communicate Results: Prepare a way to present the results of the experiment, like in the form of a written report, a slideshow presentation, or as a display at a science fair.ДЄpplications of the scientific method include simple observation too.Draw Conclusion: Based on the data you collected, determine if there is a conclusive answer to the question as to whether a bean plant placed inside or outside will grow more quickly.You may choose to find an average between the two indoor plants to determine the 'typical' indoor plant growth, doing the same for the two outdoor plants to calculate the 'typical' outdoor plant growth. Analyze Data: Review the data and determine how the plants in both environments progressed over the course of the three weeks.Carefully record the size of each plant in a notebook. Then, each day for the three-week experimental period, observe and measure plant growth. Care for the plants in an identical way, like giving the same amount of water. Try to choose locations where the plants will get a similar amount of sunlight. Place two of these in an outdoor location, and place the other two in an indoor location. Test Hypothesis and Collect Data: Plant four bean plants in identical pots using the same type of soil.The alternative hypothesis is that there is a statistically significant difference between the two growing situations for bean plants. Construct Hypothesis: The null hypothesis is that there is no difference between growing a bean plant indoors or outdoors.For the purposes of this experiment, you might decide on a time frame of three weeks. Define Purpose: I want to know if a bean plant will grow more quickly outside or inside.Here is another example where the scientific method can be used to study the natural world.

This could be a more robust experiment as you would then have additional data to report. In the case of this experiment, you may choose to vary the amount of sugar added (during step 3 of the scientific method above) to see if it alters the results as well. Communicate Results: Report your findings in the form of a written report as an oral presentation.Draw Conclusion: Based on the results of your experiment, come to a conclusion as to whether water with sugar freezes faster, slower, or at the same rate as water without sugar added.Did the water with sugar added take a significantly longer or shorter amount of time to freeze? Analyze Data: Look at the time it took for each container of water to freeze.Write down the time it took for each container of water to reach a fully frozen level. Continue until both have completely frozen. At regular intervals of 15 minutes, open the freezer and observe the status of the water in each container. Place the two containers into the freezer. Add a measured amount of sugar to one of the containers. Test Hypothesis and Collect Data: Fill two identical containers with the same amount of room temperature water.The alternative hypothesis is that there will be a statistically significant difference in freezing time between the two scenarios.

Construct Hypothesis: The null hypothesis is that there will be no difference in how long it takes the water to freeze, whether or not it has sugar added to it.

Define Purpose: I want to know if water freezes faster on its own or with sugar added to it.

Consider how the scientific method applies in this simple experiment with freezing water under two different conditions.
