Answers questions Must be testable What is Science? Investigate and learn about our world Based on evidence A Process

� The Scientific Method is a systematic process to investigate the world around us.

� The Scientific Method is a systematic process to investigate the world around us. Step Description Example Purpose Decide what will be studied. Research what is already known. Which Laundry Detergent Cleans Clothes the Best? Hypothesis Make a prediction of the outcome If Tide is used to clean clothes, then stains will be less noticeable Experiment Test your hypothesis Wash white shirts with a 5 cm Ketchup stain in different detergents Analysis Examine your data. Look for patterns Measure stains before and after washing. Determine which stains were smaller. Conclusion State what was found out about the hypothesis Tide cleans clothes with Tomato stains better as measured by size of stain

� The Electromagnetic Spectrum is the range of electromagnetic waves arranged from highest to lowest frequency. � Things you know : UV damage, radio signals, microwaves cooking � NOT sound waves, water waves , ect. These electromagnetic waves are energy waves. They can travel through a vacuum (no particles needed) � Includes every color of light – notice our eye picks up a very small part of the spectrum � Main difference between the different types of waves are the wavelength and frequency � Wavelength effects frequency – the shorter the wavelength, the higher the frequency and the higher the energy

Crest � Trough � Wavelength � Amplitude � All waves have these properties in common – but why they are important might be different � Amplitude of a sound wave determines loudness or softness while amplitude of a light wave determines brightness �

Term Definition Reflection Wave hits a surface and bounces back Refraction Wave enters a new material and bends because of a change in speed and wavelength of the wave Absorption Some part of the energy of the wave is lost as heat as the wave moves into a new material. Light Example Sound Example Water Example

1. The main difference between waves on the electromagnetic spectrum: a. Wavelength b. wave

1. The main difference between waves on the electromagnetic spectrum: a. Wavelength b. wave height c. amplitude 2. Draw a line to Match the Key Words: Reflection Less energy Refraction Bounce Back Absorption Bend

Need Particles? S E Y Conduction: Heat transfer with objects/particles in direct contact. Example:

Need Particles? S E Y Conduction: Heat transfer with objects/particles in direct contact. Example: Hot pan on stove O Radiation: Heat Transfer by waves from a distance. Example: The sun Are particles in direct contact? Y E S N N O Convection: Heat transfer by moving fluids (liquid or gases) Example: Hot Air Balloon

� Energy can neither be created nor destroyed, only transformed � Energy Conversion: When one form of energy is changed to another. Electrical energy changed to light, sound and heat energy in a TV.

The Layers of the Earth Plate Tectonics Lithosphere: Rigid parts includes crust and uppermost

The Layers of the Earth Plate Tectonics Lithosphere: Rigid parts includes crust and uppermost mantle. A. Divergent: Plates moving apart Asthenosphere: Plastic parts (not that type of plastic! ) Here we mean material that can flow – almost melted but not quite. This would include the middle and lower mantle. B. Convergent: Two plates coming together. A subduction zone forms when one plate moves under the other. Centrosphere: Center of the Earth. Inner and outer core – both iron. Outer core is liquid, inner core is solid, Volcanoes Cinder: Dust, ash and cinder layer with lava Composite: Series of violent and gentle eruptions Shield: Series of slow gentle eruptions C. Transform: Two plates slide past each other – more like a North/South motion. Plate movement is a geologic process that can change land, mountains and oceans Earthquakes Three types of waves are created by Earthquakes. Primary waves can travel through solid and liquid layers of the Earth Secondary Waves: travel through solids only Love or Land Waves: Travel through solids only
