Homework 10/29/14

Note to Parents

Parents,
Tomorrow, 10/30/14, the procedures section of the STEM Fair Journal is due. All of the items that you listed in your materials section should be included in your procedures. Please be very specific when you are recording your procedures. Your procedures should be written so that, someone else can follow them and reach the same or similar result.

Here is an example below.

Procedure
Question -Which temperature of water ( hot, luke warm, or cold) does red dye mix into the fastest?

First, pour 250 ml of hot, luke warm and cold water into each 1.234 gram container.
Second, put 1 drop of red dye into each 250 ml of water.
Third, use the timer to measure how long it takes the red dye to mix into each 250 ml of water.
Last, record my findings.

 Please make sure that you are recording the amounts/weighs in METRIC units in your procedure section. I listed a website on the 10/23/14 homework page at the bottom of this page that converts customary units of measure into metric units of measure. Please refer to that site as needed.

Tomorrow, your child will take the Math portion of the MUST TEST. It will be the first standardized test of the school year. All of the types of problems that I have been assigning for homework on this site, will be on the test. Please review the different types of questions on tonight's homework with your child in preparation for tomorrow's test.
