Changes in Matter
These are the three states of matter.
What is liquid, gas, and solid?
This is the process by which plants capture the Sun’s energy to make their own food.
What is photosynthesis?
These are the 3 processes of the water cycle.
What are condensation, precipitation, and evaporation?
This process happens when wind, water, ice, or gravity carries sediment from one place to another.
What is erosion?
This object orbits Earth and affects ocean tides.
What is the moon?
All matter is made up of these.
What are particles?
This living thing makes its own food using sunlight.
What is a producer?
The repeating movement of water between Earth’s surface and the air is called this.
What is the water cycle?
In an experiment, this is the one thing you change on purpose.
What is a variable?
The Moon does not make its own light. Instead, it does this with light from the Sun.
What is reflect light?
Matter can be defined at this.
If the number of hawks in a food chain drops, the population of these animals they eat may increase.
What is prey?
This Earth system is made of all the solid rock, soil, mountains, and landforms on Earth.
What is the geosphere?
This is a drawing, diagram, or model used to show how a solution will solve a problem.
What is a design plan?
This is the reason we see different constellations during different times of the year.
What is Earth’s revolution around the Sun?
This forms when one substance dissolves evenly into another.
What is a solution?
In a grass → rabbit → fox food chain, this is the rabbit’s role.
What is a primary consumer?
This is the percentage of freshwater on earth.
What is 2.5% to 3%?
When rain falls, sinks into soil, and later flows into rivers or oceans, it shows an interaction between these two Earth systems.
This pattern in the sky can be observed when some stars are visible in different seasons but not others.
What is the seasonal pattern of stars?
When matter changes form, it is not created or destroyed. This idea is called this.
What is the conservation of matter?
When one population in a food chain changes, this can happen to the other populations because living things depend on one another.
What is the balance of the ecosystem changing?
What is 30%?
This model can be used to explain the repeating patterns of day/night, shadows, and seasons.
What is the Earth-Sun system?
This movement of Earth on its axis causes one side of Earth to face the Sun while the other side faces away.
What is rotation?
