Sometimes We Do Not Need Microscopes . . .
Last week we used microscopes to get a closer look at an ecosystem right outside our school. We took water samples from a small drainage ditch and could see living microorganisms inside! These biotic beings were quick but many of us were able to get a closer look. Today, we will learning about an ecosystem that is rapidly changing right before our eyes - no microscope necessary. The beaches along Lake Winnipeg have drastically changed over the winter. Due to an invasive species, home and cottage owners are finding that after the snow melted, their once beautiful sandy beaches are full of millions and millions of mussels.

Le pouding au vers de terre - Worms and Dirt Pudding "How-to" Videos
Do you like worms? What about dirt? The students of 7D, 7E and 7F sure do! Check out our videos in the comments section, showing students following their recipe! We hope you will also try out the recipe so you can use a video and follow along at home!
Bon appétit!
****Students - please click in the comments section and post the link to your video! Don't forget to also include your FIRST names only!

Earth Day, Everyday!
This years's Earth Day takes place on April 22nd, 2018, but what we really need to focus on what we can do EVERY DAY. This year's theme for Earth Day is to reduce plastic/Styrofoam waste. Today we will watch a video about students in Hawaii who are looking to make a difference, then we will write about what we can do. Finally we will share our message with the school by making some 3 dimentional art to grab the attention of fellow students.

Ok, we can make mixtures and solutions, but what if we want to separate them?
Today we will separate water from sand using three different techniques. Do you remember what they are? Filtration, decanting and sieving. You'll see today that these methods wouldn't make water ready for drinking, but these steps are used when separating water from other substances.
Your job today will be to record your observations during the experiments. If you are chosen to help as a science assistance, please be sure to record your observations when you return to your spot. Watch carefully and remember "what good scientists do!"
We have spent time look at particle theory, heat transfer and solutions/mixtures. We can use this learning to think about what happens when we want to separate mixtures. Today we will learn MANY key terms used to describe separation techniques. Later, we will create our own experiment to separate a solution and evaluate it's efficiency. We will start by watching a video, then dig deeper into the key terms.
Decanting - Izabella, Mia C.
Magnetism - Logan, Jacob
Chromatography - Kally, Ella
Distillation - Nick, Raman, Nathi, Sham, Ashish
Evaporation - Alex, Ian,
Filtration - Seairra, Hailey
This is filtration because they used a funnel to kept the mud and the water from going into the cup. The reason why that happened was because they put a piece of paper inside the funnel to collect the mud particles. The funnel kept the mud from going into the cup.
Sedimentation - Evan, B
Sifting/sieving - Ryan, Beckham, Kurt, Carson, Chris, Mia D.
The reason this works is because there are holes that when you shake the strainer, the holes are small enough to let one solute pass through while leaving the other one in the strainer. Therefore separating the two substances. - Ryan, Beckham and Carson
After looking at these separation techniques, why do you think it is important that we have methods for separating mixtures? How can filtering, decanting and sieving water and sand related to our mid-year project and our discussions around the world's fresh water supply?
Today we will read an article about a young girl who has creating a filtration system to help improve water quality. Next we will develop our own methods to separate water and sand.
