number of acorns will decrease.

• Responsive variable ( Frog) What will you measure
• Data or description of experiment – describe how you will take
data, materials, organism etc. How it will be graphed an analyzed.
• State how you will draw a conclusion. Your experiment needs to
be at least theoretically possible.

along the x-axis and dependent along the y-axis
• Mark off axes in equal increments and label with
proper units
• Plot points and attempt to sketch in the curve
(line)
• If more than one curve is plotted, write a label on
each curve ( this is better than a legend)

showing)
