States of Matter
This state of matter has a fixed shape and fixed volume
Solid
A push or a pull is called this single-word term
Force
Name 2 of the four types of energy we have studied
Thermal, Light, Sound, Mechanical
Organisms that use the Sun to make their own food are called this (one-word).
Producer
Name one rapid change of Earth's surface that we studied
Landslide , Volcanic Eruption , Tornado , Wildfire , Flood
This state of matter has no fixed shape but has a fixed volume.
Liquid
If you push an object harder, what happens to its motion? (one or two words)
It speeds up / increases speed.
Give an example of an item that produces thermal energy
Oven / Campfire
What do decomposers do?
Break down perished plant and animal material to return the nutrients to the soil.
Describe one thing that happens during an earthquake
Ground shakes, cracks form, buildings may fall.
Name the process when a liquid becomes a gas because heat is added.
Evaporation
How does the direction of a push affect the direction the object moves?
The object moves in the same direction as the push
Identify the type of energy produced by a 1-flashlight, 2-a drum, and 3- a moving bicycle
Flashlight - Light Energy
Drum - Sound Energy
Bicycle - Mechanical Energy
Name the three consumer types
Herbivore
Carnivore
Omnivore
What is a volcanic eruption? Give two effects it can have on the land.
Volcano erupts molten rock (lava) and ash; can bury land, change landscapes, and affect air quality and plants.
What must increase for a solid to become a liquid?
heat or temperature
Describe what will happen to a toy car on a steep (tall) ramp versus a gentle (shorter) ramp.
Which goes farther?
Which goes faster?
Steeper ramp → more speed and likely farther travel (unless friction stops it); gentle ramp → less speed, shorter distance.
Give an example of something that produces more than one type of energy- Explain
Example - A car produces mechanical, sound, light and thermal energy. The car moves, has a horn, has head lights and a heater.
Define Herbivore, Omnivore & Carnivore
Herbivore: eats plants. Carnivore: eats animals. Omnivore: eats both plants and animals.
Choose a natural disaster (volcanic eruption, landslide, earthquake). Describe step-by-step what happens during that event and one way it affects plants or animals.
(Example) Landslide: heavy rain or quake loosens soil → slope fails → soil and rocks move downhill → buries habitat and changes water flow, affecting plants and animals.
Give one real-world example of a gas changing into a liquid and name the process.
Condensation example — water on a cold glass; gas → liquid is condensation.
What force is always pulling everything down towards the earth?
Gravity
Explain how the Sun affects evaporation and how that relates to thermal energy
Sun provides thermal energy that warms water, causing evaporation over time even without very high heat.
Explain what would happen to animals in a food chain if a top predator (e.g., fox) disappeared.
If top predator disappears: prey populations may increase, leading to overpopulation, overgrazing and reduced plant populations
Explain whether wildfires can be beneficial to some environments and give one specific reason how or why
Wildfires can be beneficial by clearing dead plant matter, returning nutrients to soil, and enabling fire-adapted seeds to germinate.
