Scatterplots

Scatterplots:

- good warm up for intro to scatterplots

[|Labs for Data Collection]- This link connects to an extensive PDF that does a lot of exploration of functions. I was thinking about using two of the labs for data collection to use for scatter plots. The first was the ball drop...starting a ball from a certain height and measuring how tall it bounces, then changing the starting height. The second was the paper bridge...folding a bridge from a piece of paper and suspending the bridge between two equal stacks of books. Then, place pennies one at a time in the center of the bridge until the bridge collapses. Then create a new bridge with 2 pieces of paper, 3 pieces, etc.
 * [[file:Collecting Data for Scatterplots.doc]]A lab I "created" that combines three experiments...the paper bridges one from above (that has a positive correlation)...one with heating water in the microwave and seeing how long it takes an ice cube to melt in the water (that has a negative correlation)...and one that has students compare their shoe length with the number of seconds it takes them to write the alphabet backwards (no correlation).

[|Interpreting Scatterplots] This links to a document of scatterplot activities and questions to help identify the relationship between the two sets of data being graphed on the plot.

[|How's The Weather?] Lesson from USA today to construct scatterplots comparing latitude, longitude, altitude, low and high temperatures of 30 cities.
