# Make a Water Glass Xylophone

### Musical glasses are a fun way to combine art, math, music and science.

Gather the materials you need:

8 identical water glasses

water

a set of measuring cups

food coloring (optional)

1 plastic spoon

1 sheet of paper

Tape

pen/pencil

As you create this experiment. Take pictures of all of your steps.

Steps:

1. Use a measuring cup to fill each of the glasses with the correct amount of water. Use the image below as a guide.
2. For fun, you can add a drop of food coloring to your glasses or two drops to make green, orange, or purple.

3.  Label your glasses.  Use the image below as a guide.

4. With a plastic spoon, gently tap each glass and listen for the sound it makes.

5. Notice which glass makes a lower sound and a higher sound.

6. Try playing these simple songs or create your own.

7. What else can you do with musical water glasses? Respond to this post with your ideas.

The SCIENCE behind the music

The science of sound is all about vibrations. When you hit the bottle with the spoon, the glass vibrates, and it’s these vibrations that ultimately make the sound. You discovered that tapping an empty bottle produced a higher-pitched sound than tapping a bottle full of water did. Adding water to the bottle dampens the vibrations created by striking the glass with a spoon. The less water in the bottle, the faster the glass vibrates and the higher the pitch. The more water you add to the bottle, the slower the glass vibrates, creating a lower pitch.

Below is a link to a list of technology housed at the EY office.  Make sure to select Tech at the bottom of the spreadsheet.

The spreadsheet contains the title of the tech available for checkout.  If/when you decide you would like to check out something, please e-mail Jenny Henningsen, who will then put your name in the “checked-out by” section of the spreadsheet.

# #70 Algebra in Pictures

Images to create this puzzle taken from pdclipart.org

###### One of the things I struggled with when taking Algebra was the use of letters (variables) to represent numbers.  However, if we remove the letters and replace them with pictures, somehow Algebra becomes a little more manageable.

How can I spend my Math Minutes?

1. Figure out the picture puzzle above stating what the ? represents in the final “equation”.  On a piece of paper, put your answer along with your first and last name, grade, school, and classroom teacher.  Give it to your EY Coordinator (or tell your classroom teacher to “pony” it to EY at Sunset Hills).
2. Create your own picture puzzle.  I used Keynote, but you could use Explain Everything, Pic Collage, or another iPad app.  Pictures for your puzzle can be found at https://www.pdclipart.org/ These puzzles can be emailed to Dr. Spady (ask your EY Coordinator or classroom teacher for the correct email).
3. Figure out the 11 puzzles pictured below.  On a piece of paper, put your answers along with your first and last name, grade, school, and classroom teacher.  Give it to your EY Coordinator (or tell your classroom teacher to “pony” it to EY at Sunset Hills).

Thank you Mrs. Bridwell for the inspiration to create this post!  Thank you to Mrs. Bridwell’s 6th graders for all the great puzzles below!

# #69: Snowiest February

#### Was February 2019 the SNOWIEST of all time?

###### How can I spend my Math Minutes?
1. Create 1, 2, or 3 different graphs to display the data above.  For a clearer image of the data, click here.   Use the Create-A-Graph website to make a graph of the data.  Be sure to include a title and label your axes.
• Top 5 Snowiest Februarys
• The Top 5 Snowiest Winter Seasons (Dec-Jan-Feb)
• Top 5 Snowiest Winters (Jul 1- Jun 20).
2. Take a look at the graphs in the image below.  For a clearer image of the graphs, click here.  The information in the blue box is particularly helpful in reading the graphs.  Answer any of the following questions by leaving a comment and/or leave a question for someone else to answer.
• How many times in January/February 2019 did the temperature range fall mainly in the record highs?  What about the record lows?
• On how many dates was the temperature range very small (short blue bar)?
• How many times did the temperature range fall in the average section (green)?
• What do you find interesting about these graphs?

# #68 The Math Behind Pringles

##### This Math Minute was inspired by the Pringles commercial that played during Super Bowl LIII.

Thanks to Ava and Karin too for your help!

I’ve always been intrigued by the shape of Pringles, but this commercial took it to the next level and had me pondering the mathematics behind this beloved chip!

How can you spend your Math Minutes this week?

2. Watch this video on stacking Pringles in a complete circle.  If you try it yourself, make sure to record it! 🙂  Check out Cooper and Jack’s attempt!
3. A Pringles can is a cylinder that is 30 cm tall.  The circles at each end of the can have a radius of 4 cm.  Find the surface area and volume of the can.  Click here for help with the formulas.  Turn in your work to the EY Coordinator at your building.
4. Create a package that will hold a single Pringle.  Send it to yourself (or a friend) in the mail and see if your package kept it protected during its journey (didn’t cause it to break).
5. Check out this interactive Pringle stacking website! https://www.pringles.com/us/wowyoucanstackpringles.html Leave a comment with the combination you think would taste the best!

The #spadyboys had a friendly Pringle Stacking Competition/Taste Test the other night.  Check out the video!

#### parade | pəˈrād | noun

##### a public procession, especially one celebrating a special day or event and including marching bands and floats.

Who doesn’t love a good parade?  People throwing out candy from elaborately decorated floats, listening to marching bands while baton twirlers dance by, watching the line of fancy cars drive by with kings and queens waiving…the list goes on!  Have you ever participated in a parade?  What is something you remember?  When I was in 4th grade, I dressed up as one of the orphans from Annie and walked in my hometown parade.  My little sister was Annie and my older sister was Miss Hannigan.

One of my favorite holiday traditions is watching the Rose Bowl Parade on New Year’s Day.  This year marked the 130th parade in Pasadena, California.

How can you spend your Math Minutes?

• Read about the Parade here: https://tournamentofroses.com/about/ and post a “number fact” about the parade.  For example:  45.5 Million people watch the parade on television and 700,000 (estimated) watch it live. Source Feel free to post as many facts as you like.
• Create a Infographic about some of the data you found out about the parade.  Check out Violet’s example.

#### The Nebraska Robotics Expo will be held at  Strategic Air Command & Aerospace Museum on Saturday, February 16, 2019.  Westside would like to take 3 TEAMS to this amazing event!

Mr. Harold Sanchez, a Loveland parent, will be holding workshops on Saturdays in January to prepare for the event.  All 4rd-6th grade students at Westside Elementary Schools are invited to attend. Even if a child decides he/she does not want to participate in the Expo, they are still welcome to attend the Saturday workshops.

Descriptions of the Robotics Expo events can be found by clicking the links below.

Please fill out the form to reserve your spot for the Saturday workshops.  They will be offered on January 5, 12, and 26 (all Saturdays) in the Swanson Public Library (9101 W Dodge Rd, Omaha, NE 68114) basement.

There is only space for 20 participants at each workshop. Students will be working on teams.  If a child wants to be part of the teams participating in the Robotics Expo, he/she should be prepare to attend all three workshops.

• 3:00-3:30 pm: General information about the event, and set up.
• 3:30-5:30 pm: Practice
• 5:30-5:45 pm: Clean up and closing

During each workshop, we will be practicing the activities.  If possible please bring a roll (or 2) of painters tape to assist in setting up the games/activities.  If your child plans to participate in the autonomous course (programming), it would be ideal for you to have a laptop computer (PC or Mac) with a USB port and the CEENBoT Commander software downloaded.  The CEENBoT Commander software can be found here: https://www.ceenbotinc.com/updates
