Draw a Best Fit Line and Predict From It

Teach the four string pitch sheets in order as a mini investigation. Use the claims, best fit line and error sheets as skill practice before or between them.

Plot snowy tree cricket chirps against air temperature, draw a best fit line and spot the outlier. The directions on the page read: Read the passage. Plot each data point on the grid, draw one straight best fit line, and find its slope. An answer key is included.

Yes, both. We made it for 8th grade scientific method, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

A testable question names one thing to change and one thing to measure. Write a Hypothesis About String Length and Pitch has students rewrite vague questions about a plucked string. They then name the independent, dependent and controlled variables.

First look for a likely cause. On Test String Length and Pitch With Repeated Trials, a tuner app sometimes reads double, so that reading is left out of the mean. Students name the cause from the note before they find the mean.

The abstract sums up the whole study, the method tells what was done, the results give the numbers and the conclusion says what they mean. Present String Length and Pitch Findings has students sort ten notes into these sections. They also plan a poster.
