Science Lab #3: Pure Substances & Mixtures pg.20-21

Context:
·         Pure substances like table sugar or salt and aluminum are matter that contain only 1 particle.
·         Mixtures like juice, cookies and steel are matter that contain 2+ particles.
·         Many mixtures we use on a daily basis (i.e. cleaners, batteries, lights, paints) contain hazardous pure substances that are harmful to us and the environment; as such, they must be disposed of at a designated facility – not the garbage can.

Purpose:
We will conduct an experiment to test a sample of matter to determine whether or not it is a pure substance containing only 1 particle.

Hypothesis:
If we mark a strip of filter paper with a water-soluble black marker and expose it very close to water, then we think…  because…

Observations:
Procedure:
What we see happening:
Exposure to water after 1 min.

Exposure to water after 5 mins.


Analysis:
Is the ink in a black marker a pure substance or a mixture?
What evidence supports this conclusion?

Conclusion:

What did you learn about the common products we all use on a daily basis?

Numeracy

+/-/x/÷ fractions with unlike denominators

Part of collaborating on a team task is to share and build knowledge together and to use that know-how to create and share an artefact for others to use and comment on.
Keeping this in mind, your goal is to create a how-to YouTube video that explains (using a combination of oral and visual aids) how to either add, subtract, multiply or divide mixed fractions in an easy-to-follow format for the typical intermediate student.
Tips & success criteria:
·         Your goal is to support and clarify a concept
·         Refer to our many corrected examples and select any 1
·         Watch related videos for ideas then add your own twist
·         Draft a script aimed at a target audience
·         Engage audience - create a hook to interest
·         Focus on skilled communication: logical, step-by-step, understandable
·         No faces - clear voice(s), words, pictures, numbers, digital/handwritten
·         Should you decide to use MovieMaker, you will need to save your file as a .wmv file to upload to www.youtube.com/stsimongr7
