Mineral Madness

Learning about Luster: Dull, Glassy, Metallic

What's the difference between a mineral and a rock?  Not sure? Well, the fourth grade students learned first hand what tests are used to tell the difference!


Thanks to our generous PAC, we were treated to an excellent in-house field trip by Natural Discoveries.  Pete Money, owner and presenter, engaged the students with humor, mineral samples, a video-microscope and 3D visuals.

Mineral Samples

Properties geologists use to determine the mineral type include the following: hardness, density, color, luster, and some other secret properties.  Each of these properties were discussed.  Examples were given and students had the chance to participate in these scientific investigations.

The first test included 4 samples (a brick, a piece of coral, a rock & a piece of quartz).  The group used the definition of a mineral to determine if any of those are minerals. 


A mineral is:

• a solid
• made by nature
• never alive
• has same elements inside

 Another test found a student checking the color of the mineral using a "streak test".  A mineral's color can be determined by the color of the residue left behind.  Taking the mineral sample and dragging it across a piece of rough tile will show the chemical color of the sample. This was done UNDER the microscope which was then projected onto a video screen for all to see. It showed that although Quartz comes in many colors all the 'streaks' come across as white.

Examining Mica!

Along with learning a mineral's properties, students learned how certain minerals are used in many of our everyday items.  Feldspar, for example is used the making of porcelain and china.  Quartz is used in computers and graphite is used in pencils.  Through the use of the above visual students had a great understanding of the uses of minerals today.

This presentation was a great way to get kids excited about Earth Science.  Pete said that the best thing about rocks and minerals is that you can find them right outside your door! Don't be surprised if your budding geologists starting bringing home samples!


 

Plimoth Plantation Field Trip

"How Now!" or "Good Morrow!"  These were just some of the greetings we heard today as we stepped back in time to the year 1627.   

Leaving Boyden during the pouring rain didn't damper our spirits as we eagerly awaited the sights, sounds and smells of Plimoth Plantation in Plymouth, Mass.  Students glimpsed what life would be like for the Pilgrims and Wampanoag people of the 17th century.  

In preparation for our trip, Kathy Devlin (Maggie's aunt) who portrays Susannah White Winslow in the Village, spoke with the fourth grade last week via Skype.  She gave suggestions on how to make the trip more meaningful.  Asking lots of questions, offer to help someone with a chore and speak to many people about the same subject, she felt would provide a wonderful learning experience.  With these tips we were ready for an exciting visit.

Making our way through the pathways to the Pilgrim Village and the Wampanoag Village really gave one the feeling of stepping back in time.  The rustic paths led our group to Pilgrims and Native people who were dressed in authentic clothing.  The pungent smell of wood smoke from the cooking fires filled the air.  Buildings and fences looked like those only seen in books. The damp weather contributed to the feeling of authenticity.  


Hopefully, students will have a greater appreciation for the finer comforts that we so take for granted.  After seeing small one room homes (which often housed six to ten people), beds on roped frames, thatched roofs, glassless windows and dirt floors, students learned that life in the late 1600's was rather harsh.  

We spent just over 2 hours touring the villages, but it felt like it was the blink of an eye.  It was a wonderful day filled with learning and wonder.  Ask your child to tell you about their favorite part of our trip.
