Will sending you back to school this year cost a fortune?

With high inflation rates, supply shortages, and rethinking what is essential spending, back to school spending might be different this year. Back-to-school spending is huge and students might not appreciate what it costs to send them back to, essentially, their job of learning.  In this activity students decide what equipment and supplies are necessary, estimate how much that will all cost, confer with classmates to refine their lists, and then research to find out more accurately how much it will probably cost to send them back to school.  This activity could be used for students in upper elementary school all the way to high school.  It offers an opportunity for kids to estimate, research, reason, calculate and communicate with each other.

But it didn’t sell?

A&W offered a bigger, tastier burger but it didn't succeed in grabbing customers away from the hugely popular McDonald's quarter pounder. The A&W third pounder hamburger cost the same as McDonald's quarter pound burger but customers still didn't bite. Studies found that Americans thought that one-third of a pound contained less meat than a quarter of a pound. Wow!

Hexadecimal coloring

Probably most of us have heard of and even used hexadecimal color codes. Don't you wonder why their number descriptions really make sense?

In this activity we first ask students to color in our Golden Spiral by giving them the hexadecimal codes of the colors that we want them to use.  Then we help them begin to understand which number weights between 00 and FF have the strongest values and how they blend.

All of our digital devices use light blending to create colors.  Why not begin to understand how that works.  Enjoy!

How much pee is in this pool?

After chlorination, it has been hard to measure the quantity of pollutants in pool water.  A Canadian chemist, Xing-Fang Li, has found a marker for urine that chlorine doesn't disguise.

In this activity, students calculate volume of several pools, change that cubic foot volume to gallons of pool water, and try to approximate how much urine is in each pool.  You might kick this activity off with this silly clip from the 2010 movie Grown Ups, where Kevin James is caught peeing in the pool.
