Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test surfaces. Using an eye dropper to deliver various fluids onto the surfaces, students determine the volume and mass of a liquid that can sit on the surface. They use rulers, scales, equations of volume and area, and other methods of approximation and observation, to make their own graphical interpretations of trends. They apply what they learned to design two super-surfaces (from provided surface treatment materials) that arecapable of holding the most liquid by volume and by mass. Cost of materials is a parameter in their design decisions.

Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. Using a paper cut-out shape of a parrot sitting on a wire coat hanger, they learn that their parrot exists in stable equilibrium — it returns to its balancing point after being disturbed. The weight of its tail makes the parrot balance upright. Give the parrot a push, and she knocks off balance, but swings back and forth until coming to rest in balance again.

This YouTube video addresses the issue of how history has effected the lives of Aboriginal peoples in our country. Presented by Truth and Reconciliation Commission of Canada.

Lyrics:
From unmarked graves their bones cry out;
"Don't let what happened to us be forgotten"
Indian hunters were paid for each scalp by the government.
You have nothing to be proud of, my white friend.
but, it's your world. it's your world.
And, if ever there was a perfect crime...
if ever there was a perfect crime...

I grew up in an empty room in a foster house full of strangers.
every dream i had about going home never ever did come true.
They lie broken like the promises that litter every street and every alley in your world. In your world.
And if ever there was a perfect crime...
if ever there was a perfect crime...

From ourselves we hide, from the darkness deep inside.
You took away our pride. And you'll never know what you have done.

If ever there was a perfect crime...
If ever there was a perfect crime...
If ever there was a perfect crime...
If ever there was a perfect crime...

if ever there was a perfect crime...

From unmarked graves their bones cry out; "Don't let what happened to us be forgotten"

A fun way for students to learn the periodic tabel its understand its layout.

This clickable periodic table give facts about each of the elements. Also, learn the history of the periodic table.

Students explore their peripheral vision by reading large letters on index cards. Then they repeat the experiment while looking through camera lenses, first a lens with a smaller focal length and then a lens with a larger focal length. Then they complete a worksheet and explain how the experiment helps them solve the challenge question introduced in lesson 1 of this unit.

This is an activity about the basic properties of magnets and magnetism. Learners explore concepts such as magnetic fields and polarity, which form the basic ingredients of a study of Earth's magnetic field and the technology of magnetometers. Materials needed include bar magnets and paper clips. This is Activity 1 of Exploring Magnetism: A Teacher's Magnetism Activity Guide.

Students investigate how different riparian ground covers, such as grass or pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model river. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.

In which John compares and contrasts Greek civilization and the Persian Empire. Of course we're glad that Greek civilization spawned modern western civilization, right? Maybe not. From Socrates and Plato to Darius and Xerxes, John explains two of the great powers of the ancient world, all WITHOUT the use of footage from 300.

This editable excel template allows users to document and track personal monthly investments, savings, income and expenses.

In this project students will use their math skills to determine how much money they can make in a minimum wage job, and are then given the opportunity to try to build a budget based on their income.

This project will also give students an opportunity to reflect on some of the difficulties that may occur as they try to budget based on minimum wage and the choices and sacrifices that may need to be made.
