MMII: The Earths CrustPembina Trails workshopKelly McBride, OCTMarch 14, 2016Prospectors and Developers Association of Canada Mining Matters
bringing knowledge and awareness about Canadas geology and mineral resources to students, educators and the general public
My name is Kelly McBride. I am a teacher who works at Mining Matters. In this position I get to educate teachers, students and members of the general public about rocks, minerals, metals, mining and career opportunities in the mining industry. I work to develop curriculum based educational resources. I also get to coordinate with other interested partners in developing educational programs and materials such as events like this one.0

Mining makes it happen!1
Today we are going to explore the teacher resource kit MMII: The Earths crust. This resource is one that is cross curricular and touches on multiple strands of the grade 7 curriculum.
The EarthMining makes it happen!2
We are going to split into 3 groups for this activity. Each team will take a rope, labels and clothes pins and use them to create a model of the inside of the Earth. Stretch out the rope and determine which end is the innermost part of the Earth and which end is the outermost part of the Earth. Use the clothes pins to attach the labels and to determine how deep each layer goes. With the dry erase markers add any details you can think of about each of these layers, including its physical state (solid, liquid) and its composition.
Generally speaking, an Earth material is defined as a resource that comes from Earth
Humans get many Earth materials by digging into the Earths crust
The Earths crust is a thin layer of solid rock that makes up the Earths outer layer
T3: The Building Blocks of RocksMining makes it happen!3
Take a look at the 4 samples in the bag. Which ones are minerals and which ones are rocks? Why? What clues did you use to make your decision?
When getting your students to do this provide them with hand lenses. This will allow them to extend their sense of sight.
Review definition of mineral and rock.3
T3: Mystery MineralMining makes it happen!48 testsDensity and relative massHardnessStreakCleavageConductivityMagnetismLustreChemical properties
Each of these tests examines 1 of the physical properties of minerals. The tests have been set up around the room. Working as a small group pick 4 minerals to observe. As a group go through each of the tests and record your observations. Once you have gone through all the test take a look at the description chart and identify the minerals.
This activity focuses on observation skills. How easy or difficult did you find this? How do you think your students will find this?4

The kit no longer includes Common Ground, and has been replaced with Ground Rules. Chapter 3 of the DVD focuses on Mining in the Modern world and some of the ways we use mineral in our daily lives.
On a piece of chart paper brainstorm some of the ways you use minerals on a regular basis?5
T2: Rock Classification ChallengeObserve and identifyMining makes it happen!6
Review what the 3 rock groups are and how they are formed.
In groups look at each of the rocks in your bag. Go through and record your observations. Once that is done sort them into the 3 rock groups. Look at the Rock Description chart. Identify each of the rocks you have based on your observations.6

T3: Mining OperationsMining makes it happen!8
Take out the Surface Mine poster and Underground Mine poster. Compare and contrast. What do you notice about each? How are they different? How are they similar?8

Manitoba?Mining makes it happen!10
What is in Manitoba?
Take a look at the geology of Manitoba. - What do you notice? What is where? Why is it there? What questions does this map make you want to ask?

All participants will be needed for this activity. Can everyone come to the side and stand in a row close together12
Volcanoes Mining makes it happen!13
This is a game that can be done in a relay. For the purpose today we are going to go through some of the cards and determine where they should end up once they have been used; will they be recycled, reused, end up in a land fill, or do they require special handling? 13
SummaryKey MessagesThe Earth has many layers. The resources we extract from the Earth come from the surface.Minerals can be identified by their physical characteristicsRocks can be classified by the processes that form themThere are many active mines in ManitobaEarth processes affect the landscape and what resources are available in an area

I hope everyone had a great time and learned a lot today. We appreciate your feedback as it allows us to grow as a company and as presenters. Another reason we ask that you fill out the feedback form is that it grants you access to certain perks offered by Mining Matters. Because you attending this presentation you now have access to our field trip subsidy program which can grant up to $500 to you for your students to take an earth science related field trip. Application need to be in by May 15. field trip must be taken by June 10.We want you to know that we are here for you. Please feel free to contact mining matters. We are happy to answer questions and direct you to interesting earth science opportunities. Mining Matters runs a national contest called the WHERE challenge. Students between the ages of 9 and 14 are asked to chose an everyday item and then figure out What on earth is in your stuff? And WHERE on earth does it come from? for the chance to win cash prizes.
Ensure that teachers have signed the database sheet and included an e-mail so that they can be e-mailed a follow-up e-mail
