What are the three laws of motion?
The Law of Inertia; The Law of Acceleration; The Law of Reaction
How do we study physical science?
Physical science is studied though observation, experimentation, and classification.
What is created by natural processes like erosion, weathering, volcanic activity, and tectonic movement.
Landforms are created by natural processes like erosion, weathering, volcanic activity, and tectonic movement.
What causes seasons?
The rotation of Earth on its axis causes seasons.

Mountain- Known for a dark coat, a large body, and medium-sized ears and nose.
Fill in the blanks:
Cells form _____ that form _____ that form ______ that form organisms.
Cells form tissues that form organs that form organ systems that form organisms.
What type of energy is needed for a chemical reaction?
Chemical energy is needed for a chemical reaction.
A student builds a circuit and begins testing different components in the circuit. The student tests a light bulb, a motor, a buzzer, and a hot plate. When the student used each component, what was the electrical energy being converted to?
Light bulb - Radiant (Light)
Motor - Mechanical (Motion)
Buzzer - Sonic (Sound)
Hot plate - Thermal (Heat)
What are the steps in the scientific process?
Observe; Question; Hypothesize; Experiment; Analyze; Report
What is the energy source made from decomposing biological matter found in the Earth's crust called?
The energy source made from decomposing biological matter found in the Earth's crust is called fossil fuels.
What significant impact does the Sun and ocean have on the water cycle?
The Sun evaporates water and the ocean acts as a reservoir for precipitation runoff.
How does the abiotic soil, the biotic grass, the biotic mouse and the biotic decomposers interact, via nutrients, within an ecosystem?
The soil feeds the grass. The grass feeds the mouse, the mouse feeds decomposers in the soil. The decomposers return nutrients to the soil.
Name two of the four features that humans have that allows one to be balanced bipedal.
The features our body has that allows us to balance and walk include a strong curved spine, a short wide pelvis, angled femurs, and arched feet.
Students poured water and olive oil into a beaker. The students then added a penny, a plastic paper clip, and a cork to the beaker. They recorded their observations.
"The oil was above the water. The penny was at the very bottom. The cork floated on the oil. The plastic paper clip sank through the oil but floated on the water."
Using these observations, list the five items in the beaker from most dense to least dense.
Penny, Water, Plastic paper clip, Olive oil, Cork.
Using three different types of energy, explain how batteries in a flashlight can make the lightbulb shine.
The chemical energy in the battery is converted to electrical energy in the flashlight. The electrical energy is converted to light energy as the lightbulb shines.
What are the quadrivium?
Arithmetic; Geometry; Music; Astronomy
Starting at magma, describe how a mineral can travel through the rock cycle. Include the following terms: compaction and cementation; cooling and crystallization; heat and pressure; igneous rock; magma; melting; metamorphic rock; sedimentary rock; sediments; weathering, erosion, and deposition.
Magma undergoes cooling and crystallization to turn into igneous rock. Through weathering, erosion, and deposition, pieces of igneous rock become sediments and move. As the sediments settle, they undergo compaction and cementation, turning them into sedimentary rock. As sedimentary rock gets heated and pressure is applied, it changes into metamorphic rock. When the metamorphic rock heats up, it melts back into magma.
Name 12 of the 16 landforms we talked about in class.
Alluvial fan; Arch; Archipelago; Beach; Butte; Caldera; Canyon; Delta; Dune; Fjord; Mesa; Mountain; Peninsula; Plateau; Valley; Volcano.
Axis deer are an invasive species of deer found in Texas which eat grasses, flowering plants, and shrubs which is a similar diet of other native herbivores. If their population continues to grow, what consequence does this have on the Texan ecosystem?
There is now more competition for the same limited food sources and overgrazing the land will cause increased soil erosion.
Within the nucleus of a cell, there are chromosomes. How many chromosomes do humans typically have and what are they made out of?
Humans typically have 46 chromosomes that are made of DNA (or deoxyribonucleic acid).
A student is building a computer but her CPU and GPU keeps overheating. She installs a heatsink which spreads the heat out over a larger surface area. The heatsink is most likely made of what material? Is the material a conductor or insulator?
The heatsink is most likely made of metal which is a conductor.
Rachel is playing tennis. She swings her racket and hits the ball. Using each law of motion once, explain what is happening to the ball before, while, and after she hits the ball.
The Law of Inertia states that the ball will travel in a straight line at a constant speed until it is hit by the racket.
The Law of Reaction states that as the racket hits the ball, the ball will also hit the racket with the same force and in the opposite direction.
The Law of Acceleration states that the force applied by the racket will accelerate the ball in the direction the force is applied.
