This week students will be learning how to evaluate websites and identify reliable sources of information before beginning their research on the solar system and extreme environments.  They will also be learning how to take key word notes and paraphrase the information.

 

Today we had a virtual field trip with Green Bricks about air quality and biodiversity. Students explored sources of air pollution, discussed the effects of air pollution on biodiversity, and reviewed ways we can all reduce the harmful effects of air pollution and keep our planet healthy. They also learned about ozone and smog and how wind currents off the ocean tend to move air pollution further inland.


Students are encouraged to take the FUN AIR QUALITY audit to explain how to keep our air clean.  For each completed audit we will be entered to win prizes for our classroom. Good luck everyone!

Spuds in Tubs

Check out how much our spuds have grown since Spring Break.  Harvesting will take place in June.  How many potatoes do you think these plants will produce? Put your predictions in the comments section of this thread.


Lesson Objectives

In this lesson students are learning about:

  • owl habitats
  • food webs and predator and prey relationships
  • owl adaptations
  • pellet formation
  • bone classification-anatomy and physiology of different species
  • conservation
  • stewardship of owls and other species

Planting Potatoes

| 1 Comment

  1. Today we planted our seed potatoes prior to spring break. We will harvest the potatoes in June. Our class predicts that we will grow approximately 100-320 potatoes.

On Wednesday we had a virtual field trip on zero waste and circular economies. Students learned about the 3Rs and examined why it is so important to reduce and re-use our resources.  They explored the “how to” for recycling and composting and discovered solutions for sustainable waste management and how to remake materials and products to be used again and again, mimicking natural cycles in nature.

Students are encouraged to take a waste audit for homework for a chance to win a $100 gift certificate of our choice or a pizza party for our class.  To complete the audit click on the link to take the fun WASTE AUDIT or follow the steps below:

While it is still winter we are starting to see signs that Spring is on its way.  Can you see where the daffodil bulbs are starting to sprout? Before you know it Spring will be here and the daffodils we planted this fall should be in full bloom.


     During todays virtual field trip we learned about the 3 local watersheds in Metro Vancouver (Capilano, Seymour, and Coquitlam). We learned that the Watershed is not a shed its actually part of the ecosystem and has many interconnected parts that are important to protect.
     So what are watersheds and what do they do? A watershed is an area of land that drains surface water and groundwater into a common water body, such as a creek, stream, lake or the ocean. In British Columbia water sheds down from the mountains into a lake or the water reservoir of our local watershed. Dams help keep the water in the reservoir.
     In British Columbia there are 400 watersheds that provide residents of British Columbia with Fresh drinking water. Of these 400 watersheds only 4 are protected.  Three of the protected watersheds are located right here in Metro Vancouver.
     Watersheds are closed to the public and people are prohibited from swimming, hiking, or fishing in these protected areas.  This helps keep our water supply clean and protected.
     The largest watershed in Metro Vancouver is located in Coquitlam.  Residents of the lower maintained get their drinking water from different watersheds.  For example, Richmond gets their water from the Capilano watershed while residents of Port Moody get their drinking water from the Coquitlam watershed.  Here in Burnaby we get our water from the Seymour watershed. When one reservoir is low or contaminated, cities must then get their water from a different watershed temporarily.
     During today’s field trip we also discussed how humans borrow water from the water cycle and why it is important to conserve water.  Did you know that it takes approximately 1 day or 24 hours for your water to travel from the reservoir to your tap. This is an average amount of time but it also depends on where you live and how close or far away from the watershed you are.
Quiz:
Which of the following is the most important?
A. Precipitation
B. Salmon
C. Forest
D. Reservoir
E. All of the Above
THE ANSWER IS E! (All of the above are an important part of the watershed and equally important.  Each one is dependent on the other).
What is the oldest tree in our watershed?
A. 100 years
B.800 years
C. 500 years old
D. 1000 years old
The ANSWER IS D.  That is a very old tree.
     For homework we were then tasked with finding out how much water we use and asked to think about ways we can conserve more water.  Click the link below to complete the water audit and get entered to win a pizza party for our class.  Good luck!

People from Fortis BC talked with us today virtually about different forms of natural gas energy. We learned about LNG (Liquid Natural Gas), RNG (Renewable Natural Gas), and CNG (Compressed Natural Gas). LNG is natural gas that has been cooled down to liquid. RNG is Gas that is created from compost and is renewable. CNG is an eco-friendly alternative fuel for vehicles. Another thing the class learned is that if you smell rotten eggs go outside and call Fortis BC or 911 until it is safe to go back inside. We also learned about ways to conserve energy. Some of the ways we can conserve energy is to keep doors shut, close windows to keep warm air in, take shorter showers, and use technology less and unplug when your not using it. These are only some of the ways you can conserve energy. We also learned that if you are doing any digging on your property you should call Fortis BC to get a free map of where the gas pipes are located around your house. You should always be careful near pipe line markers and avoid digging or using heavy machinery in the area. Activities that are okay to do in these areas where the pipelines run include walking or biking.

On Monday students from Division 3 participated as a class in an interactive virtual workshop with Relay Education facilitators using Google Meet.  Students:

  • learned about renewable and non-renewable energy
  • discussed the pros and cons of various types of renewable and non-renewable forms of energy
  • participated in demonstrations with model wind turbines
  • completed science equipments to determine how the length and number of blades on a wind turbine change how much energy is produced
