As we continue our study on sustainability and take a closer look at where our items come from, we will now look at what happens AFTER we are done with them. Clothing waste is a incredibly large scale problem and many don't realize it. When we donate clothing, we may think we are helping the less fornutate or making a sustainable choice, but is that really the case? Let's take a closer look today at where close go after we no longer want them.

Conduction, Convection and Radiation - Oh My!
Heat is the energy that makes molecules move. Molecules with more heat energy move faster and molecules with less heat energy move slower. We also learned that as molecules heat up and move faster, they spread apart and objects expand (get bigger). This is called THERMAL EXPANSION. (Text taken from the following Heat Transfer Article)
Today we will be taking a closer look at how heat transfer works. We will be reading an article, taking notes, and making informative posters to help us when we make our solar cookers. To start, let's watch a video to get us thinking!
HEAT - Brainpop
Your job today will be to highlight the key words and concepts in the article and make it into an easy to understand "poster". We will be working as a class to gather information.
Supplies you need for today are a highlighter and a pen/pencil.

How to we choose the books we read? What makes a good book, "good"?
What makes a "good" story, "good"? Is it action? Suspense? Drama? Good laughs? A good story can have all of these things or something completely different but no matter what, a "good" story needs to connect with the reader!
In 7E and 7F we have asked ourselves why we pick the books we do. After looking closer at our reading preferences, we are able to better select future books. We can also then share our book recommendations with other students who may like to see if they like the story too! Please check out our jot notes! Soon we will share with you our personal book recommendations and maybe you will find your latest "good" story!

Pure Substances vs Mixtures
Ever open a soda water, have a few sips, close up the cap and put it back in the fridge? What happens when you forget about it and decide to drink it a few days later? Is it still full of fizzy deliciousness?! Probably not. Soda water is an example of a mixture, a solution in fact, of CO2 (Carbon Dioxide Gas) and H20 (liquid water). What about soft drinks? Those are solutions too with the addition of sugar.
Today we will look at a variety pure substances and mixtures. We will learn new vocabulary and make diagrams to show our learning. Later, we will do a matching activity to show our understanding.
It is important to know what happens when we mix things because while some mixtures are delicious others can be toxic. It's also important to note than in Science we often talk about food but you should NEVER taste an unknown substance, solution or mixture to decide what it is.
Let's start with a quick video. While watching, I am going to pause along the way. Your job will be to take "quick" sketchnotes or jot notes so you will have the proper terms and vocabulary for our discussion later.

The world is filled with materials that can be distinguished into pure substances and mixtures. Read to know the differences between them.
Matter is the stuff everything you see around yourself is made of. For years, scientists have devoted themselves to studying properties of matter. This quest ultimately led to the discovery of the building blocks of matter which are atoms and molecules. The atom is the smallest unit (particle) that makes up an element. An element is a pure substance consisting of a single type of atom (ex: nitrogen, oxygen, gold). A molecule is a union of one or more atoms. There are about 100 naturally occurring types of atoms that can combine together in various ways to create zillions of different types of molecules. These molecules and elements can further combine together to create mixtures of various kinds. Thus, atoms combine in various ways with each other to create the complex world that you see around yourself.
What is a Pure Substance?
It is something which cannot be divided into parts by physical means, as it's all made up of the same thing. Pure substances are either elements or compounds.

What is a Pure Substance?
It is something which cannot be divided into parts by physical means, as it's all made up of the same thing. Pure substances are either elements or compounds.
·
Elements can NOT be separated into
other types of matter (physically or chemically). Therefore, elements are pure
substances.
o
Ex: Hydrogen gas is a pure substance, as it is made up of only
Hydrogen atoms or molecules. Carbon, gold, & nitrogen are other elements
(pure substances).
·
The atoms of elements can combine to form compounds (that have a chemical formula), that cannot be physically
divided into their separate atoms, but can be separated by a chemical reaction.
Compounds have only ONE set of properties!
o
Ex: water (H2O) and table salt (Sodium Chloride-NaCl). Pure substances have unique physical and
chemical properties (boiling point, color, smell, density…).
What is a Mixture?
Mixtures are a random blend, containing various types of two or more pure substances, which haven't chemically reacted with each other. Mixtures can be physically separated (filtering, sifting, evaporation). The pure substances that mix keep their own physical and chemical properties—a mixture doesn’t have its own unique properties.

Mixtures can be physically separated (filtering, sifting, evaporation). The pure substances that mix keep their own physical and chemical properties—a mixture doesn’t have its own unique properties.
There are two types of
Mixtures:
·
homogeneous (hoe-ma’-jen-us) –evenly
mixed (you can’t see the different parts)
o
ex: kool-aid, tomato soup, saltwater,
·
heterogeneous-unevenly mixed (can see
the different parts).
o
Ex: trail mix, chicken noodle
soup, chocolate chip cookies, pizza
Differences Between Pure Substances and Mixtures
The prime difference lies in the fact that pure substances cannot be physically separated while mixtures can be. The separation of a mixture into its different parts is done by using physical techniques like distillation, filtering and particle separation. A pure substance, any compound or element, can’t be separated into different atoms by physical methods. A chemical reaction must occur to separate a compound into its different atoms/elements.
Unlike mixtures, which have no fixed ratios of elements (it’s not even!), compounds are created from the combination of atoms in specific proportions (like in H2O, there is a ratio of two atoms of hydrogen to every oxygen molecule).
Remember that pure substances are compounds and elements (made up of the same atom or same molecule respectively), while mixtures are an assortment of different substances put together.

Where in the World Did You Get That?
When we head to the nearby shopping mall or grocery store we often look for what we need, find the size, colour, texture, shape, or fit that suits us best, check the price, and if we are good with it, we buy it. Sometimes we forget that the items we purchase often don't originate from the location we buy them from. For our mid-year project, our Social Studies component will be mapping the location (the point of origin) for 10 different personal items. We will then reflect and discuss as to whether or not where things are from matters. Specifically, does it make a difference in our personal lives, the lives of others, and the life of our planet where our possessions come from?
Where are some of my personal items from? Let's take a look. This example will serve as a model for the map you be creating and sharing with others for your mid-year projects. Beyond that, we hope through this exercise you start to think more about where the things you buy come from and whether or not you can make small or big changes that will impact the sustainability of the planet.
Let's get started!
While we are doing our inquiry, I want you to think about "What do people need to know?", "What can we do about it?" and "How can adversity, challenges or obstacles influence our environmental choices?"
- Interviews - What does "sustainability" mean to you? What stops you from making sustainably choices?

Where In The World Did you Get That? Let Me Tell You!
We have spent a lot of time critically thinking about where our items come from and we now want to share our learning with you! STUDENTS - In the comments below, please include a link to your map as well as a reflection about how your shopping and consuming habits will or will not change.

What is a Theory? Why do Scientists Use Them? What do they "prove"?
What is a Theory? Why do scientists use theories and how to they prove them? These may seem like big questions but theories are the basis of Science. Scientists in a variety of fields come up with ideas, assumptions, hunches and hypothesis and set out to prove them. This can range from researching cures for diseases to finding materials that hold in heat to keep our hot chocolate warm in the cold.
What is Scientific Theory?
What is Scientific Theory?
This term we will be focusing on "Particle Theory". This is the theory that all matter is made of particles. These particles are always in motion. They move quicker or slower depending on the state of matter it is in.
This is a basic explanation so we need to dig deeper. When studying a new topic, it is always good to learn the key terms and/or new vocabulary of that topic so we can better understand what we are talking and learning about.
One goal during our unit will be to use our new knowledge and understanding build a Solar Cooker that can "cook" a S'more. This unit also fits in with our mid-year project focussed on Sustainability. We can see that using renewable energy we can reduce our carbon footprint and reduce our impact on our planet.
Before we begin, let's discuss a few ideas.

The "Challenger" Disaster
Florida is the home of hot, humid weather, the NASA space program, and the space shuttle. Space shuttle launches seem like routine events now, with little possibility of disasters like those associated with the initial rocket launches of the 1960s. But a disaster did occur on January 28, 1986, when the “Challenger” space shuttle blew up with seven astronauts on board.
Investigators had to study pictures, videos, data from computers, design specifications, and weather conditions to piece together the cause of the explosion of the fuel tanks. Investigations led scientists to believe that the tragic event was due to a leak through an “O” ring (similar to those found in water faucets to prevent leakage/dripping of water) in the booster rockets. It was also noted that weather for that day had been uncharacteristically cold.
What caused the normally tight fitting “O” rings to leak and the subsequent explosion of the fuel tanks? Explain your thinking.
Temperature - What does it matter? Teehee!
Today we will dive into the world of temperature. The temperature of matter really has to do with how much particles the are moving, and therefore how much heat they are giving off.
To start, we will watch three experiments that highlight the affects of heat on matter.
Next, we will read an article about how thermometers work.
Temperature - Brain Pop
Next class, we will watch a video and read an article to gain a better understanding of temperature. Then we'll take a look at different types of thermometers, what they are used for, how they are made and how they work. Let's begin! Choose one of the following types of thermometers and tell me more about it. Start by organizing your paper to research using the "Cornell Method".
Next, choose a thermometer you will teach us about. You can use books, websites and videos on websites to gain a better understanding. You will be telling us about the thermometer and what it does. What are some good questions to asking when starting your research? Let's brainstorm together.
