## Hurricanes, Typhoons, and Cyclones

Graphic from http://lagoon-inside.com

This week Hurricane Fiona caused major damage to Puerto Rico, the Dominican Republic and the Caribbean,

This is the season for increased cyclonic activity around the globe.  How are hurricanes, typhoons, and cyclones related?

There is a measurement called the Accumulated Cyclone Energy (ACE).  How is it measured? Are storms becoming more intense?  Did you know there is a formula for measuring the strength of storms and storm seasons?  Let's see if this formula for measuring the intensity of storms makes any sense?

## How much caffeine are you consuming?

Did you know that there is an amount of caffeine that is too much for the growing brain of a teenager?  We did some research and have asked students to examine the sources of caffeine in their diets and calculate the number of servings that they actually consume.

## How many gumballs are there?

Gumball Machine Problem from Brian Marks on Vimeo

This problem is a little puzzle to get your students thinking, estimating, and calculating. We've given you a pdf file with only a picture of the gumball machine to use for estimating.

• How many gumballs are there?
• At \$0.25 per ball, how much will it cost me to buy them all?
• How long will buying them all take?

## Macy’s Star Rewards Points

Wow! Check out this deal at Macy's.  For \$25 I can join Macy's Star Rewards program.  I get 10% back in rewards for every dollar I spend.  Its pretty cool that Macy's gives part of that \$25 to charity.  Should you do it?  It seems like free money (or clothes) just for shopping at Macy's.  Factoring in the \$25 enrollment fee, how much do you need to spend at Macy's to come out ahead? For what total shopping dollar amounts is this a bad deal for the consumer?  What dollar amount must you spend to at least break even?  Can you write a rule that gives the dollars earned at Macy's after the \$25 registration fee for any dollar amount of purchases?

## Willy Makeit or Betty Wont

I have to go to the bathroom pretty badly. I have to admit that I have been holding it in for a while.  Finally!  I see a bathroom sign!  Wait ... it is in kilometers?  How far is that?  Should I run?

## What is Artemis 1 and when will it launch?

50 years ago we landed on the moon. We've established a space station and flown astronauts and guests to live there. Private industries have created reusable space delivery systems.  What's next?

This week, what's next (Artemis 1) was set to launch.  It is a new lift-off rocket (SLS - Space Launch System rocket) and a new crew and cargo module (Orion) into orbit. Artemis 1 will travel thousands of miles further from the Earth than has ever been flown before.

In this activity, students try to decipher several graphics that explain the flight path of the Artemis mission and make comparisons about what has been accomplished before.
