# # 94: Pixel Power

#### 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.

##### 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

# #87: Palindrome Party

### From time to time we are lucky and have a Palindrome “Week”. In 2024 we had a 10 day stretch where the dates could be written as a palindrome!

##### The date reads the same forward as it does backwards.  This doesn’t happen often!

Check out the palindrome badge at the EY website.
