If you look at all of the angles in a triangle, label them and then rip them apart, and put them together a little differently you can prove that the sum of the angles is 180 degrees.

  
 Period B was replaced today by an all candidates meeting.  We have a student vote on Thursday, and of course election day is Monday the 19th.  We got to ask the candidates running for MP questions on local and federal issues.

Today we put our knowledge into action.  The challenge was to create a square based prism 12 cm tall and a square based pyramid also 12cm tall.  The square bases could be any dimensions, but must be te same for the prism and pyramid.

planning is an important first step.

Next we measured and carefully cut out our pieces.

We used old filing folders that the school wanted recycled.

After a little tape and glue we had the solids formed.

We added the calculations for area and volume of each solid, and also the area and volume of the pair together if combined.

We can now calculate the volume of prisms, cones and pyramids.  Today we took small containers and measured them.  We then calculated how many times we could fill the small one with water and empty it into the big container without overflowing it.

pyramids and cones can be dumped three times into the prism with the same base and height dimensions.

We used two cylindrical containers next, and to prove how confident we were, someone sat beneath the container being filled.  These are the moments where you want to triple check your calculations!

   
 
We’ve graphed our bean growth and projected the trends to estimate their height on October 15th.  We used a line of best fit and extrapolated in order to do this.  We also used interpolation to determine the height of the plants on the weekends when we weren’t there to measure them.

Are we making careless errors? Computation errors? Precision errors? Or problem solving errors?

we’re correcting the quiz we recently did, and analysing the types of errors we each make.  Hopefully then we will be more aware when we write the next quiz.

Some grew 18 cm over the weekend!  Pretty impressive!

We’re graphing the progress on Wednesday.  Tomorrow is grade 9 day at Grass Creek Park, so we’ll not be in class to measure the beans.

We’re learning all about stress reduction, relaxation, and where to turn for help if we need it.  It’s important to pay attention to your self care, as well as your academics and extra curricular activities.  Emma Jane is the school’s adolescent care worker, and she is here to help!

we use the words “lemons” “cat” “turtle” “elephant” “fence” “mud” to remind us of several stretches and ways to relax our major muscle groups.

We also learned about how our feelings, thoughts and behaviours are linked.  We can have more control over our feelings if we change our behaviour and change our thought patterns.

Today we used pipe cleaners (30cm) to make rectangles with the same perimeter.  We made different rectangles and calculated the areas of each.  The biggest areas were found within the sauares.  The closer a rectangle gets to being a square, the bigger the area it contains.

We compared our results in small groups

And posted our work on the wall.

We extended the idea by trying different shapes with a 30 cm perimeter to try to find a shape that can hold more than a square.

We planted our bean sprouts today. We’re going to measure them to watch how fast they grow each day.
