Determining Variables and Constants due 12/10 or 12/11

Directions: Read page R30 & 31 on Variables and Constants. Complete the chart below. Then compare your chart to the checklist on page 13 in your science fair packet.

Variables Chart

(Title of your chart) Table 1.____________________________________________________________

Independent Variable

(What you will be changing in the experiment. Note there should only be one item listed here)

Dependent Variable

(What you will be measuring or observing)

Controlled Variable

(Constants)

(What you will be keeping the same during the whole experiment)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Measuring the Dependant Variable due 12/10 or 12/11

Directions: Read the section on Measuring the Dependent Variable on page R31 in the textbook. Then complete the chart below. Remember quantitative observations deal with measuring, (units), while qualitative observations deals with your 5 senses.

Procedures due 12/19

Directions: Complete the following on loose leaf paper or typed. Read the section on page R32 on Writing Procedures. Then read page 5 in your science fair packet online. When finished with your procedures use the checklist on page 14 in the Science Fair packet online. You should have at least 12 steps. If you are using a set of procedures already written, make sure you the directions are written to test your hypothesis. The last few steps should include repeating steps _____ through _____ for a total of 10 trials. Your last step should include write your observations on the chart

You also need to write procedures on safety. Answer the following question, what are you doing to be safe during the experiment? Be specific.

Diagrams & Pictures

You will have picture(s) of your materials and how your experiment was set-up. If people are in the picture, you will need to have them complete a photo release form. This form must be signed by their parent / guardian. If it is not, then you cannot use the picture(s). Ask Ms. Baker if you need a form or you can copy it from the website. The pictures will have to be label on top of the picture. A description of what is happening in the picture will be typed below. You can have the picture(s) emailed to your account or save it to a jump drive. Then you will be able to upload it to Word document so the title and description can be added.

Diagrams need to be drawn to scale. See Ms. Baker for more details.

The picture(s) and or diagrams will be in your report and on the display board.

 

 

 

Data Tables due 12/19

Your data table needs to be constructed before you test your experiment / prototype. The chart below is there for you to create a Title for the data table & label the columns.

Data Table 1: _______________________________________

  

Trials

(Quantitative Observation title with units) Make more columns if you are measure more quantitative observations

(Qualitative observations) Make more columns if you are measure more qualitative observations

Graph Set-up due 12/19

Directions: Label the x and y-axis of the graph. Write the increments you might use on the x and y-axis. Label the units for each axis. Remember to draw the dash marks for the increments. For more information on graphs, read pages R 24-R 27 & R34.

 Are you constructing a bar graph or a line graph? ____________________________________________
