Science Skills Observation using your senses to describe

Science Skills: Observation: using your senses to describe something Inference: a guess or prediction that you make based on the information that you have Classify: Grouping things according to how they are alike Measuring: comparing an unknown value to a standard value. Measuring can help our observations become more percice

Parts of the Earth

Mineral’s Properties are used to help identify minerals Luster: Metallic (shines like metal) Non-Metallic, clear, transparent, dull. Breakage Pattern: Cleavage: Flat sides Fracture: uneven breakage Hardness: some minerals are softer and some harder. We tested this by seeing which minerals can scratch glass Mineral Properties Streak: The color of a powder left by a mineral

Measuring Matter Mass Is measured using a Triple Beam Balance

Volume The formula to find volume of a regular shaped object: L x W x H To find the volume of an irregular shaped object use the displacement method.

Displacement

Density

Units for Measurement • Units for Mass= Grams (g) • Units for volume= cm 3 • Units for Density = g/cm 3

Density Facts Density refers to the amount of matter in a given volume. Or Density is the amount of matter (mass) compared to the amount of space (volume) the object occupies Objects that are denser have atoms that are tightly packed and objects that are less dense have atoms that are loosely packed. More Dense Less Dense

Density Facts • Objects less dense than water (1. 0 g/cm 3) will float, and objects more dense than water will sink.

What if I cut it in half? The density of each half will stay the same. Density does not change if you change the size and shape of an object.
