States of Matter
This state of matter has no fixed shape and no fixed volume
Gas
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
What is hibernation?
When an animal goes into a sleep like state to conserve energy and survive winter.
Name 3 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 is adaptation?
Changes in an animal to better survive in its environment. Ex. Ducks have webbed feet to help them swim. Predators must have ___________ to catch prey.
Describe 2 things 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
If 2 people are trying to move the same object in one direction what must they do?
The object moves in the same direction as theforce is applied, so they must both apply force in the same direction.
Identify the type of energy produced by a 1-Stove Burner, 2-a flute, and 3- a roller coaster
Stove Burner - Thermal Energy
Flute- Sound Energy
Roller Coaster - Mechanical Energy
What do fossils tell us?
What plants and animals used to live in that area.
What is a volcanic eruption? What effects can it have on the land?
Volcano erupts molten rock (lava) and ash; can bury land, change landscapes, and affect air quality and plants.
What is it called when a solid to becomes a liquid? Why does this happen?
melting occurs when there is an increase in heat or temperature
Describe what will happen to a toy car on a tall ramp.
How could you make the car go slower?
Steeper ramp → more speed and likely farther travel; lower 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.
Explain how a landslide can happen and what it would look like
(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.
What is it called when a gas loses heat and changes into a liquid ?
Give an example
Condensation example — water on a cold glass; gas → liquid is condensation.
Explain how and why the change occured?
The heavier an object the more force is pulling it down.
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.
How does removing a secondary consumer effect the rest of the food chain?
If top predator disappears: prey populations may increase, leading to overpopulation, overgrazing and reduced plant populations
How can wildfires can be beneficial to the environment?
Wildfires can be beneficial by clearing dead plant matter, returning nutrients to soil, and enabling fire-adapted seeds to germinate.
