A DATA CHART is a useful tool for recording the data you collect. You might set up your data slightly different way than it is shown here, but you need to include your independent and dependent variable, because that is what you are measuring when you test your hypothesis. Check your Variable Sheet for that information.
| Name(s): | |||||
| Homeroom teacher: | Group # | ||||
| Data Chart | Question: | ||||
| trial# | Independent Variable: measured in _____ | ||||
| Dependent Variable:
Measured in: ________

Here's an example of how you set up your Data Chart using the Cars down the
Ramp experiment that we did in class:
| Name(s): Beatrice, Shawanda and Dixon | |||||
| Homeroom teacher: Ms. Wonderful | Group # 4 | ||||
| Data Chart | Question: If we change the weight of the car, will that change the distance it travels down the ramp? | ||||
| trial# | Independent Variable: The weight of the car measured in grams | ||||
| Dependent
Variable:
How far it travels Measured in: centimeters
|
Car #1 (38g) | Car #2 (53g) | Car #3 (64g) | ||
| 1 | 41 | 33 | 62 | ||
| 2 | 47 | 30 | 70 | ||
| 3 | 21 | 44 | 81 | ||
| 4 | 22 | 41 | 74 | ||
| 5 | 29 | 46 | 80 | ||
| average: | 32 | 36.8 | 73.4 | ||
Each time they tested one of the cars, they recorded how far it traveled. Then they averaged how far each of the cars travels. Do you notice any differences between the results? After you complete the Data Chart, you're ready to look your data over and see if your data supports your hypothesis. Then you write up your Results and make a graph from your data chart.
