Graphing Tides & Moon Phases

This activity ties together spring tides, neap tides, moon phases,  chart reading skills, graphing skills, and analyzing data skills. When making the worksheets, I used the data for high tides since it showed a better range of data for the students to create the graph.

This activity was also a good review on how to create line graphs by hand for two sets of data. Students are used to making bar graphs so we reviewed how to set up line graphs and plot points on the graph.

When plotting the data, you can really see the differences in the tidal heights. We also used the phrase “Neap ain’t that deep” to remember the difference between spring tides and neap tides.
