2. Classifying Matter Matter is anything that has mass and takes up space
Matter has physical properties that can be observed
mass
magnetism
physical state
relative density
solubility
Ability to insulate or conduct heat
Ability to insulate or conduct electricity

3. Mass
Mass is the amount of matter in an object

4. Magnetism The property of attraction to a magnet
Some metals are strongly magnetic, such as
Iron
Cobalt
Nickel
Not attracted to a magnet
Aluminum
Copper
Plastic
Wood

5. Physical State

6. Density Objects with a density greater than water sink.
More Dense
Objects with a density less than water will float.
Less Dense

7. Solubility
Solubility is the ability of a solid (the solute) to dissolve in a liquid (the solvent)
Salt
Sugar
When one substance dissolves into another, we have a solution

8. Insulators of Heat and Electricity
To insulate energy means to prevent the transfer of energy
Does not allow heat or electricity to pass.

9. Conductors of Heat and Electricity
To conduct energy means to transfer energy.
Allows heat or electricity to pass from the object.

10. Properties of Water
Waters freezing point (liquid to a solid) is degrees Celsius
Waters melting point (solid to a liquid) is degrees Celsius
Waters Boiling point (liquid to a gas) is degrees Celsius

11. Changes from Heat
Adding heat means to increase the temperature of matter
Taking away heat (cooling) can change the state of matter

12. Mixtures
Some materials, when mixed together, maintain their physical properties such as iron filings and sand
Mixtures can be separated

13. Solutions
Some materials, when mixed together, undergo changes in their physical properties, such as salt dissolving in water
Must be separated through the process of evaporation

15. Energy Energy is the ability to do work
There are different types of energy
Mechanical
Sound
Thermal
Electrical
Light
We can use different types of energy
Bicycles, stereos, computers, lamps, and toasters all use different types of energy at one time

16. Mechanical Energy
Energy possessed by an object due to its motion or position
All movement is mechanical energy.

17. Sound Energy
created when an object vibrates and sends these vibrations through air
Sound energy requires a medium, such as air or water to transmit, which is why sound does not travel in space

18. Thermal Energy Also known as Heat energy
The higher the temperature the faster the particles, or molecules, of an object are moving

19. Electrical Energy
Electricity flows in a closed path to form a circuit, and stops when the circuit is broken
Conductors-copper, aluminum, and steel
Insulators- rubber, plastic, glass, wood, and cloth

20. Electrical Energy
electricity can produce light, heat, and sound when flowing through a circuit.
electric current flows to a TV, both sound and light are produced
electric current flows to a toaster, the heating element wires get hot enough to turn bread a toasty brown.

21. Light Energy
Light travels in straight lines

22. Light Energy
Light is reflected when it bounces off of mirrors or shiny surfaces
Opaque- light can’t pass
Translucent- Some light can pass
White- reflects light
Black- absorbs light

23. Light Energy
Light is refracted, or bends, when passing from one medium to another, such as from air into water
Transparent- allows light to pass

24. Science Tools Metric Ruler- 10 millimeters is 1 centimeter
Used to measure length, width, height, distance

25. Science Tools
Celsius Thermometer - The Celsius thermometer measures temperature

26. Science Tools
Spring Scale - Weight is measured in metric units of Newtons (N) using a spring scale. Weight is the force that gravity pulls on an object

27. Science Tools
Graduated Cylinders and Beakers - measure and compare metric volumes of liquids using a graduated cylinder or beaker in units of liters (L) or milliliters (mL)

28. Science Tools
Triple Beam Balance and Pan Balance- Used to measure Mass in Grams
