This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

Changes in the Hours of Daylight

Hello Everyone! I've sure been posting a lot this week...Ms. Jovanovich has kindly given us a lot of extra credit opportunities! :) 


For this extra credit, I needed to keep track of the hours of daylight each day over the past two weeks. It was very interesting to see how it changed. Below is a table of my findings:

After completing that, I needed to make a graph of my data:

The y axis should be labeled the total hours of daylight, and the x axis should be labeled the number of day in December (it begins with December 1). 


Hope you've learned a little bit about how daylight totals during the winter change! I've certainly learned a lot from this. 


Have a good week! :)
