Registration has begun for the Battle of the Books 2020!
Online registration runs through Friday, October 25.
Battle of the Books celebrates reading and fosters team spirit, and is open to all Westside District 4th through 6th graders. We are hoping to have all 10 elementary schools represented at this year’s battle on Saturday, March 21, 2020 at the Westside Middle School.
Musical glasses are a fun way to combine art, math, music and science.
Gather the materials you need:
8 identical water glasses
a set of measuring cups
food coloring (optional)
1 plastic spoon
1 sheet of paper
As you create this experiment. Take pictures of all of your steps.
Use a measuring cup to fill each of the glasses with the correct amount of water. Use the image below as a guide.
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.

80,000 tons of mobile phones and small electronic devices around Japan, which will be used in the crafting of every gold, silver and bronze Olympic and Paralympic medal awarded to athletes at the 2020 Olympic Games.
View the history of Olympic Medals at: https://www.olympic.org/olympic-medals Pick 5 different years and compare the medals from those years (designer, composition, diameter, and mint). Display your findings in a creative manner.

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?
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).
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).
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!
