True or False: Plants and animals have internal and external structures to help them survive in their environments.
True. Plants and animals have internal and external structures that support survival, growth and reproduction across multiple Utah environments (desert, wetland, forest).
When looking at an example of sedimentary rock layers, which layer is always the oldest?
The bottom layer, because it was formed first.
What is the definition of energy?
Energy is the ability to do work or cause change. It makes things happen!
True or false. The higher the amplitude, the higher the crest of the wave?
True!
What is a star?
A burning ball of gas millions of miles away! Pumba was right!
Name an external structure that a desert plant might have that would help it survive.
deep roots, shallow roots, spines (small pointy leaves), thick and wax skin
What do trilobites found in Utah's desert environment tell us about Utah's environment thousands of years ago?
Trilobites found in the desert environment are evidence that Utah has changed over thousands of years. Trilobites live in the ocean, so Utah was under water in the past.
A heavier, faster object will have LESS or MORE energy than a lighter, slower object?
MORE
What are the two main types of waves?
Hint: the way they travel
Transverse (up and down like water waves)
Longitudinal (side to side, like slinky, sound waves)
True or False. The sun and stars move through the sky?
Name a structure an animal that lives in the Utah mountains might have to help it survive in the winter.
thick fur, ability to hibernate, color changing fur, keen senses for hunting
Coal is a type of fossil formed from ancient plants that died in swamps millions of years ago. If coal is found in Utah's Uinta Mountain Range, what does that tell us about Utah's environment over time?
It tell us that Utah's environment has changed over time. If coal is found in the mountains here, it's evidence that the mountains used to be a swampy environment millions of years ago.
What are the 2 things that effect the transfer of energy when 2 objects collide.
1. Speed
2. Mass
What is the difference between amplitude and wavelength?
Amplitude is how tall or short a wave is. Measured from the wave's peak to it's resting point. Wavelength is the distance from the peak to peak.
True or False:
Objects that are closer are brighter and/or bigger than objects that are further away.
FALSE! They APPEAR brighter/bigger, but they aren't necessarily actually bigger or brighter.
For instance, our sun is a very average-sized star, yet because it's so much closer than other stars, it APPEARS bigger and brighter.
Name a structure an animal from the wetlands might have to help it survive in an aquatic environment?
fins, gills, webbed feet, breathable skin, scales
What is the main difference between a dragon fly fossil and a modern day dragon fly?
The modern dragonfly is alive and the fossil dragonfly is not.
What are the four ways energy can be transferred from place to place?
1. sound
2. light
3. heat
4. electrical currents
What causes an object to be seen?
How long does it take for Earth to make one complete rotation on its axis?
24 hours.
Animals use their senses to process information in their brain and respond to their environment. Describe this process.
The animal uses one of the five senses (see, hear, smell, taste, touch) and the receptors send the information to their nerves. The message travels through their nerves to their spinal cord and then to their brain. The brain tells the body how to respond.
The fish fossil in the bottom layer means that the environment when it first formed was under water and the top layer containing petrified wood means the environment changed over time to a forest environment with trees.
Name a device that can convert energy from one for to another.
1. solar panels
2. water wheel generator
3. wind turbine/mill
What is the type of information transfer that uses a combination of long and short signals of light or sound.
morse code
How long does it take for Earth to make one complete revolution or orbit around the sun?
365.25 days (1 year)
