Labor Day

In this short activity, students learn the meaning and history of Labor Day as they look for patterns emerging from the Labor Day dates over more than past years. Students then use those observed patterns to predict future dates of the holiday.

The numerators in the fractions have been blacked out.  What could the numerators be?  Explain your reasoning.

Back to school

In this investigation students calculate the percentage of the U.S. population (current and historically) that are enrolled in K-12 schools. They are asked to draw conclusions from these variations. Finally, they use their calculations to predict the number of enrolled students in Massachusetts.

A calculation of percent increase (or decrease) of earning power compared to education level is the final activity in this study.

Ebola is a deadly virus that has reappeared in Western Africa in an outbreak that began in February of this year.  We’ve supplied you with weekly statistics on the progression of this disease and given you and your students a few questions to assess.

Consider beginning this task by finding out what students already know about Ebola and viewing the slide show from HealthMap.org/ebola/.

In the Cloud

Clouds
I want to find a way to keep my photos, documents, videos and music in a place that is safer then on my computer.  If my Macbook Air melts, where can I keep my irreplacable files so that they aren’t lost?

Should I buy some iCloud space?  I found that I could get 5GB of storage free at iCloud.  Is that enough for my files?  Should I instead buy 10, 20, or 50 GB?

At Flikr I can get 1 TB of space free.   What on Earth is a TB?  How should I save my files?

In this activity students learn about computer memory, KB, MB, GB and TB.  They compare four different cloud providers and estimate their own cloud storage needs.
