Transcript of What animals change form in each stage of the life cycle? What does it mean to change form?
What animals change form in each stage of the life cycle? What does it mean to change form?
To become different.
How do we measure wind?
How can we tell which direction the wind is
blowing?
What might you see at an airport to help pilots monitor the wind?
Wind can be measured…
Wind sock
Anemometer
States of MatterWhen molecules are heated, what do they do?
When molecules are cooled, what do they do?
What do molecules in a solid look like?
What do molecules in a liquid look like?
What do molecules in a gas look like?
STATES OF MATTERWhen molecules are heated, what do they do?
Move further apart and move quickly
When molecules are cooled, what do they do?
Move more slowly, move closer together
What do molecules in a solid look like?
Close together, neatly arranged, move around slowly
What do molecules in a liquid look like?
Loosely arranged, slip and slide past each other
What do molecules in a gas look like?
Move rapidly, bouncing off one another, no patterns
What state of matter is air?
How can you prove air is matter?
What state of matter is air?
Air is a gas or vapor. It takes up space (think about the space air takes up in a baggie).
Conductors – what are they?
Examples?
Conductors – what are they?
Conductors help move energy
Examples?Copper pipe, glass, most metals
Energy?
What are the different types?
Types of Energy wind
sound
light
heat (thermal)
kinetic (motion/movement)
chemical
electrical
potential
Friction
Less friction-moves easily, can slip and slide (think ice skating)
More friction-resists movement, slows or stops movement (think rubber soles on pavement)
Renewable vs. Nonrenewable
Renewable resources can be replaced over a reasonable amount of time (trees, plants, wind, sun, water, and soil)
Nonrenewable resources cannot be replaced in a reasonable amount of time (think fossil fuels such as, oil, gas, coal)
What does soil provide a plant?
Soil proves minerals and nutrients for plants and trees to grow.
Fall (Autumn)*gradual falling temperatures *the noon sun appearing lower in the sky *days continue to grow shorter*plant cycles end *animals migrate south or prepare for winter sleep *some animals grow warmer fur or feathers & some change color to blend in with coming snow *the leaves of deciduous trees change color and drop off. Winter*Northern Hemisphere is tilted the furthest away from the sun *we experience our coldest season - winter. *this is the season of freezing cold temperatures, snowfall, wind, and ice. *many animals hibernate or sleep a lot to save energy *in winter there are fewer plants to eat
SpringBeginning on March 20, spring is marked by longer days and the sun higher in the sky. The Northern Hemisphere is tilted toward the sun once more, with the equator getting direct sunlight at noon. As the days grow longer, temperatures rise and plants begin to bud and start their life cycles again. Migrating animals move north and those who spent the winter in the north begin to shed their winter coats. Birds build nests, find mates and start their breeding seasons. Mammals give birth to their young. Insects hatch and begin to feed. SummerBeginning on June 21, summer is the warmest season in the Northern hemisphere. Plants grow and provide food for herbivores. Herbivores gain weight and provide food for carnivores. Mammals and birds raise their young. Insects go through their life cycles and lay eggs. Summer is when all animals, including humans, take advantage of the warmer weather to eat fresh foods. Humans grow the fresh food we will eat all year. In early times, people only ate the fruits and vegetables they could store for winter. Now we bring fresh fruits and vegetables from the Southern Hemisphere and tropical climates, so we can have them year round.
Days are shorter in the winter, longer in the
summer.
Air CurrentsWind is created by the uneven heating of the earth.
During the daytime the land heats up more rapidly than the ocean, the warm air rises and cool air blows in from the ocean to take its place.
At night the opposite occurs. The land cools quickly while the ocean remains warmer. The wind direction reverses itself and blows offshore as the warm ocean air rises and the cooler air from the land moves in to take the place of the rising air.
The earth rotating causes what?
Day and night…
If it is night, where on Earth would you be?
Facing away from the sun
Tools?What do we use these
for?microscopestelescopes
bunsen burnertongs
beakers
Photosynthesis
Sunlight drives photosynthesis.
Sunlight is the energy or force that helps plants create their own food.
Leaves collect the sunlight (like solar panels).
Producers vs. Consumers
Producers are plant life (some are found above ground or even in water, like seaweed).
Consumers eat producers or even other consumers: omnivores, carnivores, herbivores
Life Cycles
All plants and animals go through a life cycle.
A plants’ life cycle includes: germination, growth, and then reproduction/adult.
Some animals change form or can go through a complete metamorphosis/incomplete metamorphosis (larva, pupa, nymph, adult, etc..)
Weather…
Fronts are formed when two air masses meet up.
Cold air is heavier
Warm air is lighter
Cold fronts occur when cold air slides up under a warm air mass.
Warm fronts occur when warm air slides over cold air and forces it down.
Climate..
Climate is observed over a ______period of time.
Weather is observed over a ________period of time?
Moon Phases
The lunar cycle/moon phases are a repeating pattern.
You will see a new moon every month.
• If the last full moon was on May 25, when will the next full moon appear (approximately)?
Shadows
• What time of the day is your shadow the shortest?
• What time of the day is your shadow the longest?
