**TABLES**

Some data are best presented in a table format. Here are tips on how to correctly present a table. Remember to include a description that goes ABOVE the table.

**GRAPHS**

Graphs come in many types: Line graphs, Bar graphs, Scatter plots, Pie charts, etc. The best fit for the data will depend on the experiment. Remember to include a description that goes BELOW the graph.

ThomasHey, Im not sure if i have variables or not. My project is about surface tension. I put objects on water and canola oil to see if surface tension holds them up or not. Please help me i only have a few days (2 days)

Dr. Maille LyonsThomas – you do have variables!

Your INDEPENDENT variable is the “thing” you varied or changed. It sounds to me like the objects were different ? so if you put different objects on oil and water then this was one of your independent variables. The other INDEPENDENT variable would be the liquids. Water (sounds like your control) and oil (your experimental situation)

Your DEPENDENT variable is the “thing” you measured. It sounds like you either counted yes/no for if the liquid held up the object or maybe you timed how long it took before the object fell through? Either way, your DEPENDENT variable is the yes/no condition or the time.

Cheers,

Dr. Lyons

AnnetteI am trying to show results for comparing popcorn popped. One is butter the other is extra butter. Can you give me some ideas on how to set up the results?

Dr. Maille LyonsMake a bar graph. Put whatever you measured on the y-axis and label the different types of popcorn on the x-axis.

AnnetteShould I include pictures?

Dr. Maille LyonsAbsolutely – pictures make the board more interesting and attractive and frequently make it easier to understand what was done.

QuenmumMy son science fair project is changing 3 ingredients in making cookies…adding more sugar, adding milk instead and by adding oil… Is this a bar graph and if so how? Thanks

Dr. Maille LyonsAs long as you measured something that generated a number, then what goes on the y-axis with the “treatment” on the x-axis = 1 bar for each treatment (more sugar; milk no oil; third change).

You could measure cookie diameter; cookie height; etc. it must be a number, not just “that one looks best”

Good luck

MelanieMy daughter is doing a science fair project on added decomposers. The experiment she did was slicing an apple and having yeast added to some of the slices and nothing added to the other slices. How would we do an graph on something like this??

Dr. Maille LyonsWhat did she measure?

Time to decomposition? Percent decomposition? Weight loss of Apple?

Whatever was measured goes on the y-axis; you would make a bar graph with (nothing/control) as one bar and (yeast) as the other bar.

MelanieWe have kept track of the time of decomposition, and have taken pictures to show the difference of the two apples slices ( one with yeast added and the other with nothing added) What would the experimental variable be and the controlled variable be?

MelanieWe have kept track of the rotting difference between the two apples one with added yeast and the other with nothing being added. We have taken pictures over a 2wk period. What would the experimental variable be and the controlled variables??
