The Milk in Your Cereal the Pavement Outside Your House the Glass in Your Windows Ketchup

The milk in your cereal…the pavement outside your house…the glass in your windows… ketchup… gasoline…shampoo…all of these are pure substances or mixtures that you use or rely on every day. But how are these everyday products made? And how do they affect the environment and society?

You will be listing the 20-25 substances and mixtures you use on a regular basis. This can take many different forms. For example, you could make…

 You could make a map of your home/community with photos and captions of the various substances in the various rooms/locations.  A schedule that shows the places and times you use each substance, displayed like an agenda page.  A chart organizing the substances you use by category (i.e. home, school, transportation)  A slideshow that shows all the substances you use by category or time

You must classify each substance you choose as a pure substance, homogenous mixture (solution), or a heterogenous mixture (mechanical mixture) and explain why you classified it in this way. You should do this in chart/table form. (see reverse)

Lastly, and most importantly, you must choose at least 5 of the MIXTURES and explain in more detail how they are made and what their effect is on society and/or the environment.

So to recap…you must hand in:  The map/schedule/chart/slideshow with pictures and words of your 20-25 chosen pure substances and mixtures  A chart or table classifying each of your substances  Your analysis of the creation and impact of 5 of your mixtures  Your rubric

Item Pure Substance, Evidence Solution or Mechanical Mixture? Ketchup Solution It is made up of more than one particle (water, tomatoes, sugar, etc.) but you cannot see them. It is very smooth. Shampoo Solution It is made up of more than one particle (ammonium chloride, glycol, plant extracts, perfumes, etc.) but it only looks like one substance. It is smooth. Orange Juice Mechanical Mixture It is made up of more than one particle (water, oranges, sugar) and you can see them  it has bits of pulp in it. Aluminum foil Pure substance It is only made up of aluminum particles, hammered into a very thin sheet. Part C – The analysis

Aluminum foil: - Aluminum foil is actually a good product to use for packaging because it is recyclable, reusable and it is readily available on Earth. - Aluminum foil keeps heat in food so it doesn’t have to be reheated; therefore, we don’t have to use as much energy. - It is easy to re-melt foil if it is clean. - Even if foil goes to landfill instead of being recycled, it is not toxic to soil or ground water. - Therefore, even though it takes some energy to MAKE the foil in factories, it is actually quite a good product to use (versus plastic wrap).
