Earth Science
This process breaks rocks down into smaller pieces called sediment.
Weathering
This state of matter has a definite volume but takes the shape of its container.
Liquid
Ability to camouflage is an example of a/an what to improve survival?
Adaptation
This type of material allows electricity or heat to flow through it easily.
Conductor
If you are standing in a dark room and shine a flashlight at a mirror, the light bounces off and hits the wall. This "bouncing" of light is known as what?
reflection
Earth completes one full rotation on its axis every ___ hours
24
f you dissolve 5 grams of salt into 100 grams of water, the total mass of the solution will be exactly this much.
105 grams
This is the process by which plants use sunlight, water, and carbon dioxide to create their own food.
Photosynthesis
A preliminary version or "test model" of a design is called this.
Prototype
After a rainstorm, a puddle on the school sidewalk disappears even though nobody mopped it up. This is a two-part answer: Name the state of matter the water turned into, and the process that caused it.
Evaporation
When wind or water drops sediment in a new location, it is called this.
Deposition
True or false: matter never disappears
True
These organisms, like fungi and bacteria, break down dead plants and animals and return nutrients to the soil.
Decomposers
This property describes how much "stuff" or matter is packed into a certain amount of space. (Hint: It determines if an object will sink or float in water).
Density
Most people think trees get their "bulk" and weight from the soil, but they actually build their wood primarily using a gas they "breathe" in from the air. Name that gas.
Carbon Dioxide
While the Moon doesn't actually change shape, these occur because we see different amounts of the Moon's sunlit side as it orbits Earth.
Moon phases
Unlike the ocean, this type of water is found in lakes and rivers and is what humans need to survive.
Fresh water
List the four needs of plants and what they produce
Food (nutrients), water, sunlight, air --> oxygen
If an engineer's first design fails, they should do this next.
Redesign
You notice your shadow is very long in the early morning, but very short at noon. This happens because of the change in the Sun’s ______ in the sky.
Position/angle
The Sun appears to rise in the East and set in the West because of this specific movement of the Earth.
Rotation
Most of Earth’s freshwater is actually frozen and trapped in these
Glaciers
A scientist observes a bird building a specific type of nest and a dog learning to "sit" on command. Which of these is an inherited instinct, and why?
The bird building a nest
An engineer needs to choose a material for a new cooking pot handle. They should choose a material that is a "thermal ________" so the person's hand doesn't get burned.
Insulator
A scientist finds a fossil of a sea shell on the very top of a high mountain. What does this tell the scientist about what that land used to be like millions of years ago?
That it was underwater millions of years ago
