       MIXTURES AND SOLUTIONS

January 8, 2017

Dear Family, 


    Our class has begun a new science unit,
Mixtures and Solutions. We will be studying basic concepts in chemistry, and finding out how materials interact with each other. Students will learn what happens when simple materials, such as gravel, salt, and water, are put together. They will also learn techniques for separating the resulting mixtures and solutions. As our studies continue, we will investigate combinations of materials, such as baking soda and calcium chloride (the salt used to melt ice on roads), that react when mixed to produce new products—chalk, carbon dioxide gas, and table salt. We will engage in an engineering challenge dealing with desalination.

    One of the most demanding intellectual activities in the enterprise of science is developing descriptive, explanatory models to advance the understanding of complex natural phenomena. Models provide intellectual structures to important ideas that are inaccessible to direct observation. But bringing understanding to the inaccessible is a critically important dimension of science. We expect students to develop their first, primitive models of the particulate nature of matter. Their models at this level will be incomplete and limited, but expect them to have some interesting intellectual experiences as they grapple with explanations for the commonplace phenomena they observe.

    You can bring chemistry to life at home by exploring familiar household materials in a scientific way. Some of the interesting chemicals you may have on hand include baking soda, baking powder, alum, table salt, Epsom salts, flour, sugar, cornstarch, and vinegar. Add to these a few pieces of “laboratory equipment,” such as jars, margarine tubs, plastic cups, and spoons, and you are ready to extend the classroom experiences into your home. Reminder: Just as we do at school, you and your student should review and follow important safety procedures, even when working with familiar materials.

 

  • Have a plan before starting an investigation.

  • Avoid skin contact with experimental materials. Clean up spills immediately. Rinse with water if materials contact skin, eyes, or clothes. Wash hands after completing experiments.

  • Never taste the experiments. 

     We are looking forward to many weeks of exciting investigations with mixtures and solutions. You can get more information on this module by going to www.FOSSweb.com.

Sincerely, 
Bethni Albright

 

SCHOLASTIC
Book Orders


We are collecting book orders to turn in ANYTIME!!!

Book order flyers will be sent home as they are available, however, you can now order online with ease of ordering from any catalog.  I am hoping we are able to earn enough bonus points to update our classroom novels.  In the past, we've been able to purchase needed novels for a reading unit, add new books to classroom libraries, and get book samples for students.  Thank you parents for your support!

The online Scholastic code is HYDTG.  You can access and order online using this code.  Please let me know if you have any questions.
