SCIENCE 7: DENSITY of regular shaped objects
Essential Questions: 1.How do you calculate the density of regularly shaped objects? 2.How can calculating density determine the identity of an unknown? Density •The ratio of an object’s mass to its volume. •Density = Mass /Volume Volume •The amount of space taken up by a quantity of matter •Often measured in cubic centimeters (cm3) •1cm3 = 1 ml volume = L X W X H Mass •The amount of matter in an object •Measured with a triple beam balance or a scale •Units – grams Density of a material remains the same regardless of how much of the material is present. SCIENCE 8: WAVES 101 Essential Questions: 1.How do matter and energy interact when waves are generated? 2.What are the three main types of mechanical waves? 3.What are properties of waves? •Transverse Waves •Longitudinal Waves •Surface Waves Wave Vocabulary •Crest – where the displacement of the medium is at a maximum •Trough – where the displacement of the medium is at a minimum •Rest position – where the medium shows no disturbance. Amplitude •The vertical distance between a peak or a valley and the resting position in a transverse wave. •A measure of how compressed or rarefied the medium becomes in a longitudinal wave.
