11. SOL 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.
12. SOL 3.8- Earth Patterns, Cycles, and Change The tilt of the Earth causes seasons. When one hemisphere is experiencing summer, the opposite hemisphere is experiencing winter. The sun rises in the East And sets in the West Tides are caused by the gravitational pull of the moon
13. SOL 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
14. SOL 3.9-The Water Cycle The energy from the sun drives the water cycle. Water is a natural resource and needs to be conserved. evaporation condensation precipitation
15. SOL 3.10- Resources natural events and human influences can affect the survival of species recycling Air pollution conservation Floods
16. SOL 3.10- Sources of Energy Renewable resources Nonrenewable resources Fossil fuels: coal, oil and natural gas Sources of energy: sunlight, water, wind, wood and fossil fuels
17. SOL K.5- Sink or Float sink float Some objects will float on water, while others will sink. float sink wood fruit paper metal metal
18. SOL 1.2- Moving Objects straight circular curved back and forth: vibrations Examples include: humming, strumming a guitar, or plucking a rubber band The motion of objects may be:
19. SOL 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 water Things that will not mix easily easily in water vinegar milk baking soda powered drink mix sugar salt Oil sand soil rocks
20. SOL 2.2- Magnets A magnet is a piece of iron that pulls things that are also made of iron or nickel. Similar magnet poles repel , opposite poles attract .
21. SOL 2.6- Weather Common types of storms floods blizzard Tornado hurricane drought
22. SOL 2.6- Weather We use various tools measure weather. thermometer Rain gauge Weather vane
