Monday, April 3rd Entry Task Copy the following exactly if they are true. If they are false, correct them to make them true. Substances you see are matter, but substances you can’t see are not matter. Mass and weight are the same thing. Formulas can be used to calculate the volume of many solids with a regular shape. Schedule: Intro to Matter Objective: I can describe characteristics of matter Homework: 1.1/1.2 RSG Please have on desk: ISN

Matter has mass and volume Matter is anything that has mass and takes up space. Matter is anything that is made of atoms If it is not matter then it is energy

Mass is the amount of matter in an object. Mass is measured using a balance, which compares the mass of an object to a standard mass. Weight is how much gravity pulls on an object. Weight is measured using a scale.

Weight changes from place to place depending on how strong gravity is. Mass stays the same because the amount of matter does not change if the object is moved.

Volume is how much space an object occupies Formula for Volume = What is the volume of a cube that has 2 cm sides?

Calculating Volume of Regular objects Calculate the volume of the text book (remember to measure in cm)

Displacement Method Used when objects are irregular in shape This is called the meniscus. What is the volume of this?

Displacement Method Take initial reading Carefully add object. Take final reading and subtract initial from final

Tuesday, April 4th Entry Task Define an element. Is it a pure substance? Explain why. Schedule: Matter combines to form different substances Objective: I will explain how elements and compounds are related Homework: Output page Please have on Desk: Journal open to 1.1 notes & volume math

Matter Matter has _________ and ___________ In the Matter box, Describe atoms Describe molecules Remember, atoms and molecules are ALWAYS in motion!

Atoms Atoms are the smallest basic unit of matter. Atoms are really, really, really, tiny (5 x 1023 atoms in a teaspoon of water!)

Molecules Atoms can bond together, or combine. When they do this they form what we call a molecule. Molecules can be made out of atoms that are the same or different. A water molecule, H2O, is two hydrogen (H) atoms, and one oxygen (O) atom. Oxygen we breathe is O2

Matter can be pure or mixed A pure substance has only one type of component. One type of element only One type of molecule only

Elements Only one type of atom Pure Substance Number of atoms not important Found on Periodic Table of Elements Examples: Hydrogen, Carbon, Gold Non-Examples: Water, Salad Dressing, People

Compound 2 or more different types of atoms Pure Substance Ratio of atoms important (Water is always 2 Hydrogens:1 Oxygen) Bonded together Can’t be separated by physical means Examples: Water, Carbon Dioxide, Sugar Non-Examples: Gold, Chocolate Milk

Mixture 2 or more substances put together (not bonded) Not a pure substance Individual substances remain the same (Salt water) Not bonded together Can be separated by physical means (Salt water can be boiled to remove the salt from the water) Examples: Chocolate Milk, Salad Dressing Non-Examples: Helium, Water, Sugar

Elements, Compounds and Mixtures Is seawater an element, compound or mixture. How are you sure? Is the water you get from a tap at your house an element compound or mixture. How are you sure? What benefit is there to separating the parts of a mixture?

Wednesday, April 5th Entry Task Blast from the past!!! Restate the kinetic theory of matter Schedule: 1.4 Matter exists in different physical states foldable ISN 76 Objective: I will describe the different states of matter. Homework 1.4 Questions ISN 75 Please have on desk: ISN open to 1.2 & 1.3 notes & 1.1 & 1.2 RSG

Solid, Liquid, Gas foldable On the front of the foldable, draw the particles in each of the states. Include the motion and distance between particles. Inside the foldable, use the information on pages 27 to 33 to make notes about solids, liquids, and gases.

Notes: States of Matter Moving Particles Make Up All Matter! We can use the ENERGY of this movement to explain states of matter!

States of Matter: Here is the basic idea….. The state of matter of a substance is determined by how fast the particles are moving (how much KINETIC ENERGY is present) and how strongly the particles are attracted to one another!

Solids: A solid has a definite shape and volume. Particles of a solid do not have the kinetic energy to move fast enough to overcome the strong attraction between them, so they are held tightly in place. The particles vibrate in place.

Solids: Amorphous solids are composed of particles in no particular order. Examples: rubber and wax. Crystalline solids have an orderly, 3-D, repeating pattern. Examples: iron, diamond, ice, and salt crystals

Liquids: A liquid will take the shape of whatever container it is in and has a definite volume. Particles have the kinetic energy to move fast enough to overcome some of the attraction between them. The particles are able to slide past one another. The particles vibrate and rotate.

Liquids: Since particles in liquids are close to one another, it is difficult to push them closer together. They have a definite volume. This is why liquids are used in hydraulic systems, like brakes on a car. When you step on the brake, you apply a force to the liquid. The fluid applies a force, pushing the brake pad against the wheels, which slows the car!

Gases: A gas changes both shape and volume! Particles of a gas have the kinetic energy to move fast enough to overcome nearly all of the attraction between them. The particles move independently of one another. They vibrate, rotate, and translate.

Laws describe gas behavior Boyle’s Law: for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases.

Laws describe gas behavior Charles’s Law: for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature increases.

Plasma: Plasma is the state of matter that does not have a definite shape or volume and whose particles have broken apart. A plasma has so much energy that the particles have become ionized – broken down into cations and anions. Natural plasmas are found in lightning, fire, and the auroras.
