See our current unit for your current quizzes. Matter 2. Pure Substance 3. Mixture 4. Heterogeneous 5. Homogeneous 6. Solution 7. Solvent 8. State how temperature affects how quickly a solute dissolves in a solvent, and state an example from our experiments explain how it shows your point.
Name a liquid and a solid from our experiments that did not mix to form a homogeneous mixture. How do you know it was not homogeneous? Here is the answer: 1. All matter is made of particles. Pure substances are made of identical particles; no two pure substances are made of the same particles. There is space between all particles. Particles are always moving, the higher the temperature, the faster they move. All particles are attracted to one another.
You will be required to explain the reason for your answers. Name two methods for removing salt from water. Name two reasons why is it important for humans to know how to purify water? You will also have to answer a math problem based on the concentration of a solution.
These are the assignments that have been assigned for this unit. If there is no due date set, you will not submit it, simply complete it and have it in your binder. The page must have the words "Pure Substances and Mixtures" on it and at least four relevant pictures.
It is up to you to decide what else you would like to do to it. The worksheet may be found here. Properties Homework.
Assigned: Dec 15th Due: Next Period This task involved choosing three random objects, then making an extensive list of properties for each of those objects. Mixtures Lab Report. Assigned: Dec Due: Jan 26th This task involves documenting the 8 mini experiments performed in class.
The lab report is to be a full lab report, showing all of the standard sections. This is your big assignment for this unit. All information including pictures can be found here. Particle Theory Note. The contents of this note are very important, and it is expected that you have the five postulates memorized and be able to use them for the rest of the year and beyond.
Filtration Experiment. You need to have the instruction sheet and the completed questions in your binder. The instruction sheet may be found here. Review Questions. Those questions are to be answered and in your notebook. The answers are posted here , it is your responsibility to check them to be sure you have them correct.
Please see me if there is anything you do not understand. Saturation Lab. Assigned: Jan 30th Due: With Binder This task involved creating a saturated solution of sugar water, then using the measured values of solute and solvent you determined the concentration point of sugar in water.
There were also questions to accompany the experiment, which may be found here. Concentration Calculations. Air Purification Questions. Assigned: Feb 9th Due: With Binder This assignment was to read two newspaper articles and an advertisement for an air purification system, then you were to answer some questions based on that reading.

After distilling our salt solution you were to use your dried samples to answer the questions on the worksheet. Dissolve Rate Graph. Mix It Up Lab Instructions. Particle Theory. Concentration Calculations Take Up. Distillation Demonstration.
You are required to make a title page for the start of this unit. This task involved observing three common beverages with the naked eye, a magnifying glass and a microscope, recording observations, drawing observations and discussion at each stage whether the observations indicated a homogeneous or heterogeneous material.
This task involved choosing three random objects, then making an extensive list of properties for each of those objects. This task involves documenting the 8 mini experiments performed in class. This was simply a note shown in class to accompany our discussion on the particle theory of matter.
This experiment involved filtering a variety of substances and making observations throughout the process. In class you were shown 7 questions. This task involved creating a saturated solution of sugar water, then using the measured values of solute and solvent you determined the concentration point of sugar in water. This assignment was to read two newspaper articles and an advertisement for an air purification system, then you were to answer some questions based on that reading.

Combination of two or more different kinds of substances that keep their own physical properties and can be easily separated. James wants to seperate the salt from the water in his glass of salt water. What seperation method should James use?
When we speak of a pure substance , we are speaking of something that contains only one kind of matter. This can either be one single element or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties. Compounds are made up of one or more element. If we take two or more pure substances and mix them together, we refer to this as a mixture. Mixtures can always be separated again into component pure substances, because bonding among the atoms of the constituent substances does not occur in a mixture. Whereas a compound may have very different properties from the elements that compose it, in mixtures the substances keep their individual properties.
