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!
