Solubility and Mixtures Summative Review Guide

This assessment is only covering the Solubility and Mixtures part of our Properties of Matter Unit. First and foremost, check over all of the information that you have already done on your labs. Another GREAT way to study is to go over your ‘Scrapbook”. All of your learning from this unit should be in there. This was part of the purpose of this for REVIEW!

We will do a review in class on Monday March 24th in preparation for the test on Tuesday.  See me earlier if you don’t understand something!

The vocabulary for this section is:

  • heterogeneous
  • homogeneous
  • solubility
  • solvent
  • solute
  • chromatography
  • mixture
  • solution
  • saturated solution
  • dissolve
  • separation techniques – know what we have done in class: sieve, funnel and filter, chromatography, magnets, heating and evaporation
  • insoluble
  • soluble
  • concentration

Separating Mixtures Lab Debrief

Today’s lab focused on how the physical properties of matter could help us separate heterogenous mixtures. Heterogeneous mixtures contain two or more kinds of matter. Each part of the mixture retains its own composition and physical properties.  Scientists may use the physical properties of the different parts to separate a heterogeneous mixture.

 1.  Watch the following clip Chapter7-SeparatingMixtures (after the first section, click “Next” to watch the second section. Continue to click next to play the  “Game Show”)
 2. Based on what you watched in the link above, fill out the following table: (In your science notebook or use lined paper)

3. In today’s lab we used  forceps, magnet, funnel, filter paper, beaker and sieve sets as tools to help separate different parts of a mixture. What other tools could we use to separate mixtures? Try to think of at least 3 more tools.

4. (OPTIONAL) CHALLENGE: Based on what you have learned about physical properties and how to separate mixtures, how would you separate a mixture of salt, sand, iron filings and poppy seeds? Write out your method of separating the mixture and explain which tools and physical properties you would use to do so.

Wednesday, March 5

Today is a day 6B day.

Math: Complete Lesson 7.1.1 and start the beginning of Lesson 7.1.2 Today’s lesson continues to focus on comparing rates.

Science: What is the difference between a mixture and a solution? How are they separated? What methods are used to separate things? Below is a video that we watched in class to review what mixtures and solutions are. Thursday’s lab will be about separating mixtures.
