Also, list 3 solar features.
Core, Radiative Zone, Convective Zone, Photosphere, Chromosphere, Corona.
3 features: sunspots, solar flares, solar prominences.
What is doing the same experiment multiple times yourself.
Repetition
Fill in the blanks and label the atom
AND identify the element
(see sheets)
A probe traveling through outer space is moving at a constant velocity.
Which statement applies to the motion of this probe?
The force that makes the probe move through space is equal to its mass divided by its velocity.
What is the difference between a prokaryote and a eukaryote?
A prokaryote has no nucleus.
What is the relationship between gravity, mass, and distance?
The force of gravity between two objects increases as their mass increases, but decreases as the distance between them increases.
An explanation in science that is supported by a large amount of evidence from experiments and observations and accepted by many scientists.
Scientific Theory
Write the equation for photosynthesis
Write the equation for cell respiration
water + carbon dioxide + sunlight energy -> glucose + oxygen
glucose + oxygen -> water + carbon dioxide + ATP energy
A student eats breakfast, rides a bike to school, then turns on a classroom projector to watch a video. Identify the sequence of energy transformations that occur from the food to the images on the screen.
chemical energy → kinetic energy → electrical energy → light (and sound) energy?
List the following from smallest to largest:
organs
cells
organisms
tissues
atoms
molecules
organ systems
atoms, molecules, cells, tissues, organs, organ system, organism
In what two places does convection occur and why is it important to both?
Hot material rises and cooler material sinks in both the Sun and Earth’s interior; this movement not only transfers heat but also causes tectonic plate motion and solar energy circulation.
Dr. Martinez conducts an experiment and finds that a certain fertilizer helps plants grow 20% taller. She publishes her results in a science journal. A few months later, Dr. Chen reads the study and decides to perform the same experiment using the same procedures, materials, and conditions to see if she gets similar results.
What is Dr. Chen doing in this situation and why is it important?
Replication. It's important because it confirms results are reliable and consistent.
Astronauts measured a rock on the moon. Its mass was 1,500 grams and its volume was 250mL. How does the density of the rock change on Earth?
It would not change because mass and volume are not affected by gravity.
What is the relationship of frequency, wavelength, and energy in regards to the EM spectrum?
Long wavelengths = low frequency and low energy
Short wavelengths = high frequency and high energy
The first cell theory is credited to the work of Theodor Schwann and Matthias Schleiden in the 1830s, but this biological principle has changed over time.
Which of the following is NOT a premise of modern cell theory?
All cells arise from other cells.
All living cells require water for survival.
All living things are only composed of cells.
II only
Compare and contrast absolute magnitude vs apparent magnitude.
Apparent magnitude is based on the distance the star is from Earth.
Absolute magnitude is the true brightness of a star which isn't affected by distance.
What are the meanings of these root words?
Bio
Geo
Phy
Hydro
Cryo
Therm
Life, Earth, Physical, Water, Ice, Heat
The process of rusting occurs when iron (Fe) combines with oxygen (O) in the atmosphere to form iron oxide (FeO).
How would you classify iron oxide?
compound
A metal spoon is placed in a cup of hot soup. After a few minutes, the handle becomes warm. Using the correct rule for heat transfer, explain which direction heat is moving and why.
heat moves from the hot soup to the cooler spoon because heat always transfers from warmer objects to cooler objects
Mushrooms, bread molds, and yeasts are classified together in the fungi kingdom. Specific characteristics are used to classify these organisms. Which of the following is a characteristic used to classify these organisms as fungi?
They are heterotrophic.
List the 8 planets in order and name 4 key differences between the inner and outer planets.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
4 inner: rocky, smaller, no rings, few or no moons, hot temperatures, thin or no atmospheres, faster orbit around the sun.
4 outer: gas, bigger, all have rings, many moons, cold temperatures, thick atmospheres, slower orbit around the sun.
A group of students wants to find out how sunlight affects plant growth. They place identical plants in different locations: one gets 2 hours of sunlight, another gets 5 hours, and another gets 8 hours each day. After two weeks, they measure how tall each plant has grown.
Identify the independent and dependent variable. Explain your reasoning.
Independent Variable: Amount of sunlight (because this is what the students are changing)
Dependent Variable: Plant growth/height (because this is what is being measured and responding to the change)
On the periodic table, elements are arranged in horizontal rows and vertical columns. Identify what the rows and columns are called and explain why elements are grouped this way based on their atomic structure.
periods and groups (or families)? Elements are arranged this way because elements in the same group have the same number of valence electrons and similar properties, while elements in the same period have the same number of energy levels.
Scientists launch a rocket into space for a mission. Once the rocket escapes the pull of Earth’s gravity, how will the mass and weight of the rocket be affected?
The mass will stay the same, but the weight will change.
List 5 cell organelles and their primary function.
mitochondria
Golgi apparatus
cytoplasm
nucleus
cell wall
ribosomes
endoplasmic reticulum
lysosomes
vacuoles
