Light and Matter
The most reflective material we investigated
What is a mirror
The causes of Earthquakes
What is tectonic plates snapping past each other on rough edges
The science words for loudness and pitch
What is amplitude and frequency
The reason for seasons
What is the Earth's tilted on its axis. When a hemisphere is tilted towards the sun it is summer, while the hemisphere tilted away is in winter
1. The powerhouse or energy maker of the cell
2. The brain of the cell
1. What is the mitochondria
2. What is the nucleus
The way light travels
What is in straight lines
The cause of mountains shrinking
What is when the erosion rate is larger than the uplift rate
The way to determine frequency, wavelength and amplitude
What is counting the peaks
what is the distance between the starting point and the peak or valley
The two major eclipses and what happens during them
What is a solar eclipse (moon casts shadow on Earth) and Lunar Eclipse (Earth casts shadow on Moon)
The way cells reproduce
What is the cell takes in nutrients, grows, makes copies of the material inside the cell, and then split, creating two identical cells
The reason we can see a tiny reflection when we look at a transparent window
The cause of the Atlantic Ocean getting bigger, and the Pacific ocean getting smaller
What is, the Atlantic Ocean is diverging plate boundaries, the tectonic plates are moving apart and magma is coming up and filling it in. The pacific ocean oceanic plate is going underneath the continental plate since it is denser and melting in the mantle, making it smaller
Sound needs a __________ to travel.
How can you increase frequency?
What is a medium
make the sound source vibrate faster
The moon phase three weeks after a Waning Gibbous
What is a Waxing Gibbous
The structures of blood and the function of each part
What is blood plasma, liquidy, travels around body and carries nutrients, food, and the other parts of blood
What are red blood cells brings oxygen from lungs around body
What are platelets create scabs and plug openings in skin and blood vessels
What are white blood cells help fight ifnfections
The reason the music student could not see the teacher
What is even though a little bit of light was transmitting through and going to his eyes, it was competing against too great a light source
FOUR important pieces of evidence that prove Pangea existed
What is fossil evidence, glacier evidence, puzzle pieces, rock layers, coral reefs
The way to determine wavelength
what is the distance between two peaks
Changing these factors would make gravitational forces STRONGER (need to list all)
What is:
Increasing mass
Decreasing Distance
Decreasing Speed
The system that helps us move our body
What is the neuromuscular system
The reason the music teacher could see the student and herself
What is, the light hit the music student and half the light reflected off the one-way mirror and half the light transmitted through. Half the light went through, and then hit her, and then went back to the one-way mirror and then another half reflected back, causing her to see herself.
The cause of historic Marine Fossils being found on the top of Mt. Everest
What is the Indian Plate bordered ocean and coral reefs. It traveled towards the Eurasian plate, and collided, creating Himalayas. Over time, as a result of the convergent boundary, there was uplift of old rock/fossils, and weathering+erosion revealing fossils
The way sound travels from a sound source to a receiver
The process that formed our solar system
What is accretion -- particles of matter were brought together by the sun's gravity and continued to hit each other, and add on, increasing their masses until they were the perfect balance and found their way into a steady orbit around the sun.
The reason we take our hand off a hot object after touching it
What is our nerves send a signal from nerve to nerve, then to the spinal cord ad the brain. The brain processes the signal, creates a message to move your hand, and sends the message back through the spinal cord, through the nerves, to the nerves in the muscle responsible for moving that body part
