Some people feel that we should change the way we write our numbers and use a base 12 system instead of a base 10 system. What do you think? Would this be a good idea?

Additive vs. subtractive colour mixing
Check out these two online activities to see the differences between additive (light) and subtractive (pigment, such as paint) colour mixing. In class today we were working on two labs working with these colour mixing online apps. If you did not finish, please complete them for homework. The labs are due Wednesday at the start of class.

Math 8 Learning Log
Today we will be starting a new way of tracking your learning in Math. You will get a learning Log which you will be colour coding based on your understanding of concepts in Math 8 (I will also keep a copy). Every Tuesday you will have a short Quiz that will check your understanding on the topics we are working on in Math.
The Learning Log looks like this:

Wave Investgation
Today in class we worked on a Lab investigating waves with the use of slinkies. We will have some time in class on Tuesday to finish (about 15 minutes) and it will be due at the end of class.

Wave diagram
Colours are made of light with different wave lengths. Using the app in the right top corner of the blog or go to this link: http://scienceprimer.com/light-color-frequency-and-wavelength-experiment and see if you can you figure out what colours have short wavelengths and which colours have longer wavelengths. List the colours of the rainbow in order from longest wavelength to shortest wavelength and give an approximate frequency and wavelength for each. We will be charting the data in class.

Integer Extension Project
Some students in class are working on an extension project that uses Scratch, a computer programming language, to create a math game about adding and subtracting integers. Students are using this game and modifying it to quiz players on adding and subtracting integers. The game they are modifying can be found here: http://scratch.mit.edu/projects/2096713/
Open up the game and find the lists (arrays) in the Data folder. Edit the lists to make the questions and answers about integers. Change the graphics and other game components too if you think you can make it even better!
