Atoms

Standard: Student will examine the Scientific view of the nature of matter and distinguish between Atoms and Molecules.

EQ: How is the Atom structured?

An atom is the smallest particle into which an element can be divided and still be the same substance.

All substances are made of atoms. Atoms are small particles that cannot be created, divided or destroyed.

Atoms of the same element are exactly alike, and atoms of different elements are different.

Atoms join with other atoms to make new substances.

Atoms usually have as many electrons as protons.  Atoms usually have about as many neutrons as protons.

In 1877, J.J Thomson a British scientist discovered that there are small particles inside the atom.  He also discovered that they are negatively charged particles called electrons.

Atoms are made out of three basic particles: Protons carry a positive charge

Neutrons carry no charge

Electrons carry a negative charge and circle the nucleus.

these are part of the notes we took in class today.

No Homework.

chapter 4 section 3 Review

Properties of Mixtures: Today in class we took notes on the above section.  Here are the reviews.

1. A mixture is two or more substances that are not chemically combined i e that can be physically separated.

2. There are no chemical changes in a mixture.

3. A mixture do not need to be mixed in a definite ratio.

Solution - A mixture that appears to be a single substance.

Dissolving is how solutions are separated and spread evenly throughout a substance.

Important: Solute the substance been dissolved.

                 Solvent substance in which the solute is dissolved.

                 Solubility ability of a solute to dissolve in a solvent at a certain temperature.

                 Particles of an elements is an atom.

                 Particles of a compound is a molecule.

Pure Substances

Hello,

I hope you all had a terrific weekend.  well this week we are working with pure substances.  Students should be able to describe the difference between pure substances (elements & compounds) and mixtures.  Page 90-93.

We were not happy with your grades in the last test and I asked some of you to come to school this morning by 8:15 am so we could go over the differences between physical & Chemical changes but no one came.

Please take time to read thoses note you took in class today.  Trust me all you need is about one hour of study time to reinforce what was learned in class and you will come up a shinning star.  You all are already a Star but we need you to shine in Physical Science.

No homework today.

Thanks

Merrick

Study guide for science test

Hello,

I know you all have had a busy week testing, but we have our section 3 test in science.  In order to make the science test easy I am attaching a study guide and I promise if you read those sections in the study guide you will end up with very good grades.  The key again is review for the test.

Please study.

Properties of Matter

Hello,

I hope you all had a wonderful weekend, well this week we are working on properties of matter.  Students will describe the movement of particles in Solids, Liquids, Gases and Plasma states.

After this session students should be able to:

a. describe the properties shared by particles of all matter.

b. describe four states of matter.

c. explain the differences between the states of matter.

students will use a graphic organizer to illustrate the properties of states and the characteristics of states of matter.

Parents please encourage your kids to navigate the science textbook on line.  They could also practice on their skills tutor at home.

Thanks.

Quiz

Hello,

We have been busy this week with the physical and chemical changes lab.  By now students should be able to identify a physical and chemical change.  We are going to the computer lab tomorrow to work on skills tutor and reviewing for our test next week.  Students are currently reviewing page 58-59 in class this assignment is due on Friday and it will serve as a Quiz.  If you need help, I will be available in class and in the morning before homeroom.

Thanks,

Merrick

physical science

Hello,

Today in class we discussed the physical/chemical properties of Matter on page 44 in the physical science textbook.

We are currently discussing chapter 2 section 3 of the textbook.  Below are some important notes taken in class today and you need to review them for your up coming test.

1. A physical Property can be observed or measured without changing the Matter's identity.

2. State of Matter is the physical form in which a substance exists such as solid, liquid or gas. example Ice is water in the solid state.

3. Density - is the mass per unit volume of a substance.  The amount of Matter in a given space or volume.

4. Solubility - The ability of a substance to dissolve in another substance for example Cool-Aid.

5. You use Physical Properties to identify matter.

6. Physical changes do not Form new substances.

7. Chemical properties - are more difficult to observe.
