Transcript What animals change form in each stage of the life cycle?

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 Matter
When 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 MATTER
When 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
Days are shorter in the winter,
longer in the summer.
Air Currents
Wind 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?
microscopes
telescopes
bunsen burner
tongs
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?
