 For All Ages:

http://www.ccmr.cornell.edu/education/ask/?quid=742 this is a Question and Answer page, from Cornell, all about how crystals from. It’s all text so you may need to read this to younger students.

http://skywalker.cochise.edu/wellerr/students/crystals/project.htm this is a good page all about the different shapes of crystals. We’ll be making these shapes in class (for 8-12’s)!

http://www.youtube.com/watch?v=laMZAJ2L_1Y Here is a 10 min. video from Discovery Channel all about the giant crystals found in the Naica Crystal Cave in Mexico. It will amaze you!

http://homechemistry.blogspot.com/2010/03/salt-crystal-trees.html this is a great laboratory protocol for growing salt crystal trees at home. It’s quite easy and done with household items.

For Parents:

http://www.hometrainingtools.com/captivating-crystals-newsletter/a/1564/ this page had a neat background on crystals (at the bottom) and at the top it has two different recipes for growing crystals at home, and comparing crystal growth between borax and sugar.

Missed Class Schedule, Updates, and Rocks,

Gems and Minerals Block 2 Pre-Class


Thank you for your patience during furlough. This will be a bit longer post than usual so please bear with me. We need to address the missed classes, some changes, and pre-class materials for Block 2: Rocks, Gems, and Minerals class.

For those that missed the final class in the Ecosystems on the Edge Block of classes

We will be offering two make-up dates for the class, on Thursday, October 31st and Friday, November 1st at the normal times (9-10 am for 5-7 yr. olds on both dates, 10:30am-Noon both dates, and 1:30-3 pm on Thursday only).

You may sign up online at: www.SignUpGenius.com/go/10C0D4DACAB2CA7FA7-make. If you have questions contact me McDonaldK@si.edu.

If you cannot make either of these dates please e-mail me. We are still receiving guidance about how refunds or credits will be issued. If you wish you may donate the program cost to SERC Education, otherwise I will update you when I receive more information. Please let me know your choice when you e-mail.

Film Class Make Up:

For those in the film class we will meet at our next regularly scheduled date/time. However I will be adding one additional date, January 16th to our schedule, and we will push everything back one date.

NOTE: Because of feedback from students and parents I will be offering, in the next class, to allow students to break up into smaller groups of 2 students. Students may remain in their larger groups, or if distance and time dictates break up into smaller units. However, this may mean more work for each student. Please consider this carefully with your students before arriving in class. We will discuss this as a class and decide on final groupings. If students do break into smaller groups they may keep their original topic, or re-submit a pre-production proposal. This must be approved by me before continuing!

Homework for next class:

HOMEWORK FOR OCTOBER 24TH: Turn in final Pitch for documentary with the following for your pitch:

  • Topic
  • Goal of documentary
  • Summary paragraph
  • 3 sections of arc
  • Highlight for story boarding and have a rough draft of your story board ready to turn in.

You are going to have to communicate with your film crew to accomplish this homework. Please be sure to have some means to communicate with them, either digital, phone, or in person meeting lined up.

READ: Chapter 7 in “Shut up and Shoot” about interviewing.

Student Citizen Science Data/Math Opportunity with Bluebird Population Data:

I have an opportunity for one or two students that are proficient in Excel, to do some mathematics and modeling using real life data. We’ve collected bluebird nesting data for the last 6 years (2008-present). We would like to graph this data and do some visualization of population trends. If your student is working in Excel or might be interested in adding this to their curriculum please let me know. It can be done at home. Probably would be best suited for ages 13+. Please e-mail me with question (McDonaldK@si.edu).

http://www.youtube.com/watch?v=9Xv1DoqkARQ Watch this video (23:05) on Rocks by Bill Nye (my favorite!). You may wish to try the Epsom salt exercise in the video at home. It takes about 24 hours to set.

http://www.youtube.com/watch?v=pg_jKJFbA2A&list=PLDEQMJ4WTcWohAvf48MWaGaIjOoK8FQLE here’s a quick video (8:36) about the three different types of rock. You should watch this before trying the rock hound quiz.

http://www.fi.edu/fellows/fellow1/oct98/create/index.html explore the three links to discover how the three types of rocks are formed.

http://www.fi.edu/fellows/fellow1/oct98/expert/index.html study the rocks (in red) and then take the “Rock Hound Quiz” at the bottom of the page to see if you can tell which is igneous, sedimentary, and metamorphic.
