1 Matter Types of Energy Science Tools
Science STAAR Review Matter Types of Energy Science Tools

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

29 Science Tools
