LEARNING GOAL & SCALE

585% & Above

In addition to Level 4, I can make connections to real-world applications and content in other Investigative Science units.

475%

Mastery

I can correctly: Describe substances based on their physical properties.Describe substances based on their chemical properties.Predict properties of elements and compounds using trends of the periodic table (e.g., metals, non-metals, bonding – ionic/covalent).Describe the following features and components of the atom: o protons o neutrons o electrons o mass o organization o structure o number and type of particles

360% I can correctly complete most of Level 4.

250% I can correctly complete Level 4 only with guidance.

125% I am unable to complete Level 4, even with guidance.

What students will be able to apply by the end of this course?Students use scientific processes: questioning, planning and conducting investigations, using appropriate tools and techniques to gather data, thinking critically and logically about relationships between evidence and explanations, and communicating results.What students will be able to do by the end of this unit according to State Standards?Learning Goals:I can understand how to identify, categorize, and organize substances.

Matter Activity”

Matter

Matter

• Anything that has mass and takes up space (volume)– Examples:

• A brick has mass and takes up space • A desk has mass and takes up space• A pencil has mass and takes up space• Air has mass and takes up space

All of the above examples are considered matter because they have mass and take up space. Can you think of

anything that would not be considered matter?

Mass vs. Weight

Physical Properties of Matter

• any property of matter that can be observed or measured without changing the identity of the matter

• Examplescolor shapetaste

state/phasedensity D = m

V

Chemical Properties of Matter

• any property of matter that describes a substance based on its ability to change into a new substance

• Examplesflammability

reactivity with vinegarreactivity with oxygen

Iron + Oxygen Iron oxide (rust)2Fe + 3O2 Fe2O3

Chemical or Physical Property?

1. Paper is white

2. Boiling point of H2O is 100oC

3. Zinc reacts with hydrochloric acid and creates hydrogen gas

4. Nitrogen does not burn

5. Sulfur smells like rotten eggs

Helium Less dense than air Nonflammable

Wood Grainy texture Flammable

Baking soda White powder Reacts with vinegar to produce bubbles

Powdered sugar White powder Does not react with vinegar

Rubbing alcohol Clear liquid Flammable

Red food coloring Red color Reacts with bleach and loses color

Iron Malleable Reacts with oxygen

Physical Change

• a change in shape, size, color, or state• a change without a change in chemical

composition• a change that is reversible

– The Mixtures Lab• Examples

tearing paper cutting your hair change in state

Changes in States(Physical Changes)

Melting

Vaporization

(Evaporation/Boiling)

Freezing

Condensation

All changes in state require a change in energy

Disposition

Why do you think Bose-Einstein and plasma are not equally distanced

from the other three states of matter?

Ionization

Recombination

Phase Changes Simulation

• PhET

• Harcourt School

• Pearson

This is what happens when energy is added and/or taken away from matter

Chemical Change

• a change in which a substance becomes another substance having different properties

• a change that is not reversible using ordinary physical means

• Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes

You usually need more than one of the above characteristics to be considered a chemical

change!

• Examplescombining sulfuric acid and sugar

burning a piece of woodsoured milk

Chemical or Physical Change?

1. Bending a Paper Clip

2. Baking a cake

3. The sublimation of carbon dioxide

4. Crushing an aluminum can

5. Vinegar and baking soda combining to create salt and water

Mass vs. WeightMass

• a measure of how much matter an object is made of

• does not change, regardless of where something or

someone is

Weight

• the force of gravity on an object

• equal to the mass of the body times the local acceleration of gravity

http://www.exploratorium.edu/ronh/weight/index.html

Why do you think the person ’s weight is less on

the moon?Mass = 59 kg Mass = 59 kg

Weight = 579 N Weight = 96 N

5 Physical States of Matter

•Bose-Einstein

•Solid •Liquid•Gas

•Plasma

(Newest State)

Bose-Einstein Condensate

• Exist at extremely cold temperatures (around absolute zero or -460 oF)

• Particles are super unexcited

• Particles lock or “clump” together so firmly that they move as a single unit

• Definite shape and volume (?)

Solid

• Particles are tightly compact

• Particles vibrate without the ability to move freely

• Definite shape and volume

• Solid Animation

Liquid

• Particles are tightly compact, but able to move around close to each other

• No definite shape, but definite volume

• Liquid Animation

Gas

• Particles can easily spread out or move close together

• Particle move freely and with a lot of energy

• No definite shape or volume

• Gas Simulation

Plasma

• Exist at extremely high temperatures (several million degrees Celsius)

• Particles are broken apart• Particles move freely and

with extremely high energy

• This form is not too common on Earth, however it is the most common form of matter in the universe

• No definite shape or volume (?)

• Examples: Florescent and neon lights, lightning, aurora borealis

Why do you think this is the most common

form/state of matter in the universe?

Energy and the States of Matter

• The physical states of matter result from the amount of energy the particles composing the matter have. Basically, more energy means more movement for the particles and less energy means less movement.

• Energy/Temperature and Matter Simulations– PhET– BEC: Temperature and Absolute Zero

If you were to compare an ice cube and the steam created from boiling water, which would you think has more energy?

What about this continuum could be considered a little misleading?
