          Quarterly  Drawing

NEW OPPORTUNITY for CAST members to win CLASSROOM MATERIALS

Visit this page often to learn about materials you may want to use in YOUR science classroom. We will provide information about the materials and strategies plus a way to enter the drawing in order to win science materials to use in YOUR science classroom. We will have a different drawing each quarter of the school year!

Quarter 3 Drawing = Economical, Portable Microscopes 


Quarter 3 Drawing is now OPEN!

DRAWING # 2 - January, February, March - 2019

This drawing is for current CAST members only. You may only enter this drawing once a month - once in January, once in February, and once in March. Duplicate entries will be deleted. The drawing will be held on March 20th and winners will be notified by e-mail.

A NEW drawing will be posted for Quarter 4 in April, 2019.

Want to have your SCIENCE students ‘take a closer look’ at the world around them?

Check out these newer, economical versions of microscopes for your science students to use.

These microscopes could definitely be used with biology students, but there are many applications of using microscopes in learning within other sciences. Students can use a microscope to observe crystals, minerals, and rocks in an Earth Science or Geology course. Chemistry students can use a microscope to observe chemical reactions such as the reaction of silver nitrate with copper metal. In biology, students can use microscopes to study cells and microorganisms in pond water. In Environmental Science students could take microscopes out in the fields to observe the anatomy of small insects and to detect microorganisms in stream water or to observe soil samples. Science teachers at all grade levels could incorporate these microscopes in their teaching. Check them out here and then add your name to the form below to be entered in our Quarter 3 drawing for these microscopes.


Option 1:  Receive 3 USB microscopes for use in your science classroom. Each microscope is valued at ~ $21.These microscopes plug into the usb port on your computer and allow your students to view magnified (40-1000X) images of the materials they are observing. Click the link above to see the actual USB microscopes included in this option.

Note: There are many different USB microscopes available, this is just one possibility. If you win this drawing you may request different USB microscopes as long as you remain in the $60-70 allotment.  



Some resources regarding USB microscopes to check out:


Option 2:  FOLDSCOPE - The Paper Microscope -

“Foldscope is the ultra-affordable, paper microscope. designed to be extremely portable, durable, and to give optical quality similar to conventional research microscopes (magnification of 140X and 2 micron resolution). Foldscope brings hands-on microscopy to new places!”  

To learn more about this valuable resource click here to check out the website for Foldscope .

If you choose this option for this drawing, you will receive one combined kit which includes a single DIK (Deluxe Individual Kit - for the teacher) AND a Basic Classroom Kit (including 20 foldscopes). 21 foldscopes in all. Assembly is required. The value is ~ $70. 


Here are links to several Ted Talks by Manu Prakash, one of the inventors of the foldscope.
