A scientists uses an instrument to observe the pattern of molecules in a substance. The scientist sees that the molecules are very closely packed together. What state of matter is the scientist most likely observing?
solid
When liquid water turns from a liquid to a gas called water vapor.
evaporation
This is the phase of the Moon when it is positioned directly between the Earth and the Sun, making it invisible from Earth.
A New Moon
Why does the Sun, when looking
from Earth, appear to be
larger than other stars?
Because the Sun is closer to Earth than other stars.
Manny and Eva are dissolving sugar in 10 milliliters (mL) of water. They discover that more sugar dissolves in warmer water. In order for their results to be confirmed, another group must get the same results. Which list contains tools needed to confirm Manny and Eva’s experimental results?
a. beaker, test tube, stopwatch
.b. microscope, glass slide, probe
c. beaker, hand lens, eye dropper
d. graduated cylinder, thermometer, balance
d. graduated cylinder, thermometer, balance
True or false? Liquid can turn into a gas by adding thermal energy.
True
rain, snow, sleet or hail
precipitation
When we see exactly half of the Moon's face illuminated, it is officially known as one of these two "quarter" phases.
First or Third (Last) Quarter
What is the difference between
asteroids and comets?
Asteroids are made up of rock and metal, comets are mostly made up of frozen gas. As comets come closer to the Sun, their ice begins to melt and creates a “tail” of gas.
Two teams of students are testing the effect of light on a radiometer. Team 1 finds that blue light makes the radiometer spin slower when a blue light is 35 cm away. To validate Team 1's test results, how must Team 2 test the radiometer?
a. Test it with a red light that is 20 cm away.
b. Test it with a blue light that is 35 cm away.
c. Test it with a blue light that is 45 cm away.
d. Test it with a green light that is 40 cm away.
b. Test it with a blue light that is 35 cm away.
False.
When water falls back to earth as precipitation, it lands in oceans, rivers, lakes or on land.
Collection
A first quarter moon is observed. How does the appearance of the Moon change throughout the night?
a. The Moon will appear to become larger and change into a full Moon.
b. The Moon will appear to shrink and change into a new Moon.
c. The Moon will appear to move across the sky, keeping its same shape.
d. The Moon will stay the same shape and will stay in the same position until sunrise.
c. The Moon will appear to move across the sky, keeping its same shape.
What is the difference between rotation and revolution? Does
the Earth rotate or revolve?
When something rotates, it spins in a direction around its axis (the Earth rotates around its axis once every 24 hours). Revolution is when one objects orbits another object (the Earth revolves around the Sun once every year). The Earth both rotates and revolves.
What is the difference between an independent variable and dependent variable.
Independent variables are the factors manipulated or changed to test their effect. Dependent variables are the measured outcomes or responses that "depend" on the changes made to the independent variable.
Mass is the amount of ______ in an object and it is measured with a _________.
matter/balance
Located between the tropical zones and the polar zones. The climate is considered mild, so it can be either warm or cold.
Temperate Zone
Christina is investigating the phases of the moon. Tonight, she notices that the moon appears as a half circle, which is a first-quarter Moon. When can she next expect the Moon to appear in this phase?
In about four weeks, 28 days, or one month
Name two differences between the inner and outer planets.
Inner: rocky surface, relatively short time to revolve around the sun, smaller in size, relatively close to one another, varying temperatures
Outer: Gaseous surface, relatively long time to revolve around the Sun, larger than inner planets, further apart than the inner planets, all very cold
A student will measure and record the growth of two flowering plants every other day for 10 days. Only one pot will receive 10 mL of fertilizer and each pot will receive 200 mL of water. Which question is being tested?
Does adding fertilizer to the soil lead to taller flowering plants?
Provide an example of a physical change.
________ pressure is generally associated
with good weather and _______ pressure is generally associated with deteriorating weather conditions.
High pressure = good weather and Low pressure = deteriorating weather conditions
Michael looks up at the night sky and observes a full moon. If Michael were to observe the moon again in 7 days, in which phase would the moon be?
Third or Last Quarter
