# 94: Pixel Power

Image result for pixels are.

Pixels are the smallest unit in a digital display. Up to millions of pixels make up an image or video on a device’s screen. Each pixel comprises a subpixel that emits a red, green and blue (RGB) color, which displays at different intensities.
In this mini spark, you will learn about the basics of pixels and pixel colors.  You can extend your learning on this topic by completing the Pixel Power Badge! (coming soon)
Step 1:  Start by taking out your math notebook or opening your math mini spark doc.  Put the date at the top and put the title of this mini spark. Record all of your work on this page.

Step 2. Use this slideshow of images, which zooms a picture of raft. The final slide shows that the entire photo is actually made from individual squares of color. How does looking at these pictures help explain creation of the digital images that you see? What other images might you see today that are made from pixels?
Step 2: Watch these two videos. The first video is a reminder binary numbers. It will help to see this before watching the second video.
Take notes as you watch both vidoes.

After watching the second video answer these questions in your notebook.
What is the RGB name for turquoise?
How does a computer name turquoise?
Draw the math steps that were used in the video to explain how a function is used to filter an image.
Step 3: Turn your notes and responses to your teacher or EY coordinator.

#90: A Ridiculous Long Way to Find Out the Day of the Week You Were Born

Do you know what day of the week you were born on?  If not, you could…

  1. Ask your parent(s)/guardian(s) if they remember the day of the week.
  2. You could “Google”: What day of the week was May 16, 1975 (that’s my birthday)

OR

You can do this ridiculously long way…which is more fun IMO!

Step 1: Take the last 2 digits of the year in which you were born.

Step 2: Divide that number by 4 and ignore any remainder.

Step 3: Add the day of the month.

Step 4: Add the month’s key value.

  • January and October:Key Value = 1
  • February, March, and November: Key Value = 4
  • April and July: Key Value = 0
  • May: Key Value = 2
  • June: Key Value = 5
  • August: Key Value = 3
  • September and December: Key Value = 6

Step 5: Subtract 1 for January or February of a leap year.

Step 6:

  • Add 0 if the date is in the 1900s
  • Add 6 if the date is in the 2000s
  • Add 4 for the 1700s
  • Add 2 for the 1800s

Step 7:  Add the last 2 digits of the year.

Step 8: Divide by 7 and take the remainder.

  • Remainder 1 is Sunday
  • Remainder 2 is Monday
  • Remainder 3 is Tuesday
  • Remainder 4 is Wednesday
  • Remainder 5 is Thursday
  • Remainder 6 is Friday

Now double-check your work by searching on Google!  Bonus: Create a product that shows your work!  Look below for an example.

Step 3: Show your notes to your EY Coordinator and/or classroom teacher.

#88: EWeek (Engineer’s Week)

Calling all FUTURE ENGINEERS…Every year we celebrate EWeek.

Learn about 5 different types of engineers and solve the types of problems they solve.   https://www.mathcounts.org/resources/engineers-week

Geomatics Engineering

Geomatics engineers collect data and then analyze and interpret it to find solutions  Geomatics engineering plays an important role in construction, transport, communication, mapping and research.

Structural Engineering

Structural engineers design and analyze bridges, buildings and even things like concert stages. Environmental factors, what a structure will be used for and what type of weight will be put on it, and how this all might change from day to day before even beginning a design are all things that a structural engineer must consider.

Systems & Mechanical Engineering

Systems engineers need to ensure individual sub-systems and components of a large project all work together to perform the overall desired function. Mechanical engineering mostly work in HVAC(heating, ventilation and air conditioning).

Nuclear Engineering

What if you could harness the energy that is released by reactions within atoms?  That’s what nuclear engineering does!  The energy released by reactions within atoms can be used to generate electricity, power transportation systems, and diagnose and treat illnesses.

#87: Palindrome Week

Some times we have a Palindrome “Week”

December 1-9  in 2021 formed a palindrome when the month is written as 12 and the year is written as 21.  So…

December 1 was 12-1-21
December 2 was 12-2-21
December 3 was 12-3-21
12-11-21 and 12-22-21 were also palindrome dates in Dec. 2021.
The date reads the same forward as it does backwards.  This doesn’t happen often!

To earn this mini-spark,

  • Check out these palindromes for kids: https://kids.kiddle.co/Palindrome pay special attention to any words that are new to you and phrases that are palindromes. These items should all be included in your final note taking page.
  • Watch the video about palindromes https://youtu.be/1QC20PBvunI and pause the video as needed to record any new words/phrases that are palindromes.
  • Share your work with your teacher and/or EY Coordinators to earn this mini spark.

Where can you find 🅿🅰🅻🅸🅽🅳🆁🅾🅼🅴🆂?

Leave a comment and/or send a picture of a palindrome you discovered.
