Celebration of Learning Tuesday, Mar. 13
Come f0r a visit to see our buddy project with the grade fours. Its a fort city of epic proportions. Please see your invitation for times when you can visit!
Pi Day on Wednesday Mar. 14
Thank you in advance to all the lovely people supplying pies!
Dissection moved to Thursday, Mar. 15
Due to some Celebration of Learning clean-up, the dissection day has been moved to Thursday.
Check out this video and actively listen to understand what Reggie Watts is trying to talk to you about:
Tessellations and TinkerCad
Our wonderful STEM peeps that taught us all about scratch are back to teach us all about 3D print design. We will be applying this information to a new math project.
Details coming soon...
Dissection next Wednesday (Mar. 14)
Get in those dissection permission forms for a chance to dissect a lamb heart or beef kidney. Lucky you! You may even get to see a lamb lung in action. Stay tuned!
Field Study Monday (Mar. 12)
Ever wondered if you could walk through the aorta of a blue whale? Wonder no more; we're diving into the water unit and tying it in to biology on our trip to Telus Spark Science Centre.
Purpose: Investigate why single-celled organisms have a limited size. (I.e. Why do we not see single-celled organisms the size of an elephant?)
Task 2: Answer the following question
If the volume of a cell (contains organelles, nutrients, wastes) increases at a faster rate than the surface area of the cell membrane, what happens to the exchange of nutrients and waste?
Task 3: Post-Video Explanation
Do you need to make any adjustments or can you now refine your original explanation.
Also note 2 adaptations that may allow a cell to grow any larger than a typical cell
Dart's Insta Post
To wrap up the 3D shapes SA and Volume unit, we will be completing a journal entry. The requirements of this journal entry are 3 fold:
1. Calculate the surface area of Dart's old & new terrarium. These can be measured in class. Complete the calculations in an organized fashion to demonstrate your understanding.
2. Think deeper about why it might be important to calculate this value as a factor in Dart's well being and quality of life. Things you could think about:
3. Draw up what you think the instagram page should look.
Another Journal Page Entry
Question: What is the reason why we never see single-celled organisms the size of an elephant?
Here we will be utilizing our knowledge of surface area and volume to investigate this question. More details to come...
Science in the News
Last week, the kids picked a science news article to investigate the 5 Ws (Who, What, When, Where, and most importantly WHY)
They were to develop in partners, a 2 min presentation that outlines the 5 Ws with an emphasis on asking why questions like:
Math Practice - Quiz on Wednesday, Feb. 24/2018
This quiz will be on surface area and volume of 3D shapes + the basic components of a 3D shape in prisms and pyramids.
- What is a face
- What makes a face a base in a prism and a pyramid
* Think parallel
- Use the shape of the base to identify how to name a prism and a pyramid
Surface Area: (Prisms & Pyramids):
- Be able to identify how many congruent faces are on a particular 3D shape
- Use this information to formulate an equation to calculate total surface area (TSA)
- Be able to solve word problems using these concepts
Volume (Just prisms):
- V = Al . (Volume = area of the base x length of the prism)
- know the difference between an area and a length when formulating your equation
- How to determine the base in order to accurately calculate volume of a cylinder, triangular prism, and a rectangular prism
p. 222 --> review of concepts
p. 223-225 --> practice questions
p. 226-227 --> practice test
*Use these pages to check your understanding and come prepared to class on Tuesday to clarify any concepts that you are unclear on
A very short week
A 5 day weekend is coming up starting Thursday Feb. 15. In addition, this week is packed from Monday to Wednesday with the school dance and science olympics. Therefore, to stay on track, there needs to be some studying over this weekend.
Wednesday Feb, 21, there will be a math quiz on Surface Area and Volume. Post will soon be updated with a review guide.
Wear your colour for science olympics!
Make sure to wear your colours for the science olympics on Wednesday!
I was absent for the lab, what do I do?
I am posting the document here. For those students who want to try it at home because they missed the actual lab, it is very possible to completed at home, as long as there are parents present to deal with either isopropyl alcohol or rubbing alcohol (it MUST be chilled).
Volume of Rectangular and Triangular Prisms
We are moving on from surface area of prisms and pyramids and into volume of rectangular and triangular prisms. The question sets are as follows:
Rectangular prism volume practice:
p. 198-200 # 4-7ac, 10-13, 15-18
Triangular prism volume practice:
p. 205-208 #3-9, 11-17
Students should come prepared to go over questions that they had difficulty with, or found an interesting way to solve, so they can contribute to class examples. The 2 sets should be done before the end of this week.
The Debate is done - what do I need to hand in by Monday?
Well what a useful question! If you are wondering what needs to be handed in here is a handy-dandy checklist:
But wait, what do I need in my reflection?
Another great question! Heres another checklist:
If you have not yet completed your science journal entry (you know who you are), please get it in to me ASAP. For more specific information on what this entry entails, see previous post.
Debate day is next week on Tues. Jan. 16th. Make sure to dot your tees and cross your eyes.
Next week on Wed. Jan. 17th, the kids will be participating in an inventor's day in the morning. They are allowed to wear a hat that day (its their "thinking cap")
We have been working on calculating the surface area of 3d shapes: prisms and pyramids. The SA of prisms is due on Mon. Jan. 16th. Pyramids is due Tues. Jan. 17th. The focus here will be completing work in a specific and accurate way.

Surface area prism (google area of a polygon for assistance with the trapezoidal prisms):
Surface area pyramid (google surface area of a cone for assistance with those questions):
Create your own worksheet
Have I identified specifically what I am calculating?
Have I shown all steps in my calculation?
Is my work displayed in a clean and concise fashion?
Are all my computations accurate?
Did I include proper units?
