Energy and Matter
Popsicles on a hot summer day, or what the Wicked Witch of the West said after Dorothy threw water on her
"I'm Melting"...(aka changing from solid to liquid)
Precipitation
This fancy term describes how all scientists approach problems, test ideas, and develop explanations for phenomenon
What is the Scientific Method?
What is the Water Cycle?
The system that moves water between locations
Where (body part) does digestion begin?
the mouth
This is the process matter undergoes to change from a liquid to a solid, it's probably happening outside right now!
What is freezing
Digestion
The process by which living organisms convert matter to energy
This is the phase of the Scientific Method in which scientists test out their ideas.
What is the experimental phase?
I am a water molecule and I live in the clouds. Suddenly, I start tumbling to earth as a raindrop! What happened to bring me out of the clouds?
The temperature dropped
With few exceptions, a major difference between plant and animal life is in their energy production. While plants use photosynthesis for energy, animals must do this to survive
What is eat?
What would you expect to see rising out of a pot of boiling water on the stove and why is it rising?
Steam (because water molecules increase in speed of movement and spacing as they heat up)
Runoff
water that pools and runs across the ground after rain
The first step in the Scientific Method. This usually involves looking around the room and noticing things.
What is observation
Every year, when I visit in January, there is a large, but shallow lake in the desert out side of Las Vegas, NV. When I return to visit in July every year, the lake is always gone. What happens to the water?
Evaporation and infiltration
This organ is primarily responsible for chemical digestion, but you might feel like it rumbles like an engine 3rd hour
What is the stomach
The temperature of the air near the cold soda can decreases. As this occurs, the water molecules in the air lose energy, and _________
What is slow down?
Evaporation
Liquid turns to gas when energy is added in the form of heat and or pressure
After scientist observe their environment, they come up with an idea to explain what they are observing. Later, the scientists test their ideas during the experimental phase of the Scientific Method. What do we call the ideas that we test experimentally?
An hypothesis
Plants are an important part of the water cycle. List 3 ways that plants participate in the water cycle.
Absorbing excess water to prevent flooding, releasing water into the air during transpiration, and naturally filtering the water
If a person has diabetes, a disease in which the body does not produce enough insulin to digest the sugars in food, this organ is not functioning correctly.
What is the Pancreas?
There are at least 5 states of matter, name 3
Liquid, Solid, Gas
Condensation
gas to liquid due to energy being removed (heat removed and/or pressure removed)
Often used to describe any old idea in common use, among scientists this term means specifically an idea that has been experimentally confirmed many, many, times by many different scientists.
What is theory.
How are clouds formed
water vapor in the atmosphere begins to condense together to form clouds as the water vapor cools
This long narrow tube can reach lengths of 22 feet when it's stretched fully. You might never guess how long it is by the way it is coiled and curled in your abdomen. It needs all of that length to absorb nutrients from food.
What is the Small Intestine
