Great job on your drawings and interpretations of Plato’s Allegory of the Cave!!

This week we also learned about basic wave structure and the 2 types of waves, specifically Mechanical (like sound, water, and seismic that need to travel through matter) and Electromagnetic (like UV, x-ray, visible light, and radio that can travel with or without matter like space).

After our lesson on waves, we discussed analog versus digital signals with our graph paper “telephone” game. We showed how those signals represent information in different ways and the varying ability to accurately reproduce them. Digital signals use digits, like 1s and 0s, to code for information, whereas analog signals are analogous, or similar, to the information. Analog signals like waves can have a lot of variation and a range of values like the curvy lines of your drawings. Digital signals rely on the very basic 0’s and 1’s of binary code and logic maps to relay information – like only following the lines of the boxes of your graph paper.

This graphic shows how binary coding can be used to represent pathways through a series of “high” and “low” choices.  Following the binary code will guide the path to take on a logic map, and help in finding the intended colors.

A “1” will indicate to take the “high” path and a “0” will indicate the “low” path. With this map, called a “logic gate map”, a binary series of 0’s and 1’s can indicate when to “go high” or “go low”, conveying a path in the map to “code” for a color. For example, using the logic map above, 010 would indicate “0” go down, “1” go up, “0” go down. This will code for the color green.

HW Challenge:

  • Figure out the binary code for your favorite color using the logic map above
  • Make your own logic map for something



How is your personal study of scriptures and math going? Have you been able to make it a habit and find a regular time to do it? We love reading about the concepts and topics you are learning!



Science: “Light, Sound & Electricity”

  • Usborne Encyclopedia of Science, pgs 228-247
  • Watch at least 2 videos on any of the topics from this section of pages
    • Usborne Quicklinks site: Science

Philosophy for Kids: Questions #28, #29 and #30 (pgs 86-93)

  • Write down your thoughts and favorite parts in your notebook.



Finish up your projects this week! Remember to take pictures AND notes/measurements!

Consider re-reading through the Science Fair Project packet in your binder. Be thinking about how you would like to present your project on your display board.

Our class Science Fair is on the last day of class – Nov 17th!
