3SOL 3.2- Simple Machines *A simple machine helps people do work!* A lever moves around a fixed point called a fulcrum.A wheel and axle is made up of a large wheel attached to a smaller wheel or rod.A wedge is a made up of two inclined planes placed back-to-back
4SOL 3.2- Simple Machines, cont.. A screw is an inclined plane wrapped around a pole that is usually used to hold things together.An inclined plane is a flat surface with one end higher than the other.A pulley is a rope or chain and a wheel around which the rope fits
5SOL 3.3- Matter Objects can be described by their physical properties. A physical property is anything that can be observed using the senses.Objects are made of one or more materialsmaterials are made up of parts that are too small to see with out magnificationphysical properties remain the same when the object is reduced in size.

8SOL 3.6- Living Systems, cont.. Environments support a diversity of plants and animals share limited resourcesDry-land environmentsConiferous forestDeciduous forestrainforestgrasslandDesert

10SOL 3.7- Soil topsoil subsoil bedrock soil provides the support and nutrients necessary for plant growthtopsoil is a natural product of subsoil and bedrock;rock, clay, silt, sand, and humus are components of soilssoil is a natural resource and should be conserved
11SOL 3.8- Earth Patterns, Cycles, and Change The Earth revolves around the sun. Each time it makes one revolution, we have one year!The earth rotates on its axis which causes us to have night and day.
12SOL 3.8- Earth Patterns, Cycles, and Change The sun rises in the EastAnd sets in the WestThe tilt of the Earth causes seasons. When one hemisphere is experiencing summer, the opposite hemisphere is experiencing winter.Tides are caused by the gravitational pull of the moon
13SOL 3.8- Earth Patterns, Cycles, and Change A life cycle is all the parts of a plant or an animal's life from birth to death. The life cycle of a bird is made up of unhatched chick, chick, young adult, and adult
14SOL 3.9-The Water CycleThe energy from the sun drives the water cycle.Water is a natural resource and needs to be conserved.condensationevaporationprecipitation

16SOL 3.10- Sources of Energy Fossil fuels: Renewable resources coal, oil and natural gasRenewable resourcesSources of energy: sunlight, water, wind, wood and fossil fuelsNonrenewable resources
17Some objects will float on water, while others will sink. SOL K.5- Sink or FloatfloatsinkSome objects will float on water, while others will sink.floatsinkwoodfruitpapermetalmetal
18back and forth: vibrations SOL 1.2- Moving ObjectsThe motion of objects may be:straightcircularback and forth: vibrationsExamples include: humming, strumming a guitar, or plucking a rubber bandcurved
19SOL 1.3- Materials interacting with water Some liquids will dissolve in water, while others will not.Most substances will dissolve better in hot water than they will in cold water.Things that will mix easily in waterThings that will not mix easily easily in watervinegarmilkbaking sodapowered drink mixsugarsaltOilsandsoilrocks
20Similar magnet poles repel, opposite poles attract. SOL 2.2- MagnetsA magnet is a piece of iron that pulls things that are also made of iron or nickel.Similar magnet poles repel, opposite poles attract.
21SOL 2.6- WeatherCommon types of stormsfloodsTornadoblizzarddroughthurricane
