This model placed Earth at the center of the universe and was supported by early astronomers like Ptolemy.
the geocentric model
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.
This astronomer proposed a Sun-centered model of the solar system that challenged earlier beliefs.
Nicolaus Copernicus
What is it called when a different scientist performs the same experiment to check results
Replication
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
What is it called when the Moon passes directly between the Sun and Earth, causing the Sun to be blocked?
a solar eclipse
What is the variable you change on purpose in an experiment?
the independent variable
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
What is the force that keeps planets in orbit around the Sun?
Gravity
What is the variable you measure or observe in an experiment?
dependent variable
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.
What is the phase when the Moon appears completely illuminated from Earth?
A full moon
This variable depends on changes made in the experiment.
the dependent variable
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
