Have a great Spring Break!!!

Announcements:

• Hope you have a wonderful Spring Break!!! (see you on April 8th, 2019)
• There are extra Math and Science practice opportunities in the sections below

Math:

We finished Patterns and Relations this week. If students would like to review this chapter over the break (chapter 10) they can do practice questions on Khan Academy or IXL or they can review the textbook chapter. 

This week students practiced graphing from equations and noticing differences in graphs as equations change. We looked at graphs on Desmos and students learned how y = x is different from y = x + 3 or y = 2x. They learned that the number next to x (that multiplies by x) is called the numerical coefficient and changes the slope (steepness) of the graph and the number added or subtracted to x is called the constant and determines where the graph crosses the y-axis (y-intercept).

Some of the skills students learned in this unit include:

• Describing visual patterns (how is the pattern changing from one figure to the next?)
• Creating tables of values from these patterns comparing one variable to another
• Determining the rule (expression or equation) for the pattern
• Graphing the pattern from the table of values
• Creating a table of values from an equation using substitution

Science:

Students completed their Ice Box designs and tested them to see how well they would keep an ice cube from melting in one hour. All projects were quite successful! 

We measured how much water was in their baggies after the hour using a graduated cylinder and recorded the results. They then reflected on what they would do to improve their projects were they given the opportunity to rebuild. 

These projects will be marked over the break and marks will be on PowerTeacher. 

Thank you to the students for doing a really good job with this project!!! 

When we get back we will study types of energy. Students who would like to get ahead are welcome to research pros and cons of different energy sources including:

• fossil fuels
• solar power
• wind energy
• nuclear energy
• hydro power

Email lebowen@cbe.ab.ca if you have any questions over the break.

See you April 8th. Have a great Spring Break!!!
