Meat and plants. Ex: bear, raccoon, human
Give an example of a predator and prey relationship.

The formula for SPEED
Speed = Distance / Time
Name two decomposers.
Bacteria, fungi
When light reflects, does it bend or bounce?
bounce!
T or F - Planets closer to the sun orbit faster than planets farther away.
True
What is the sun?
a star?
Why do the moon and stars appear to change position?
Earth's rotation
In a food web, which direction should the arrows point and why?
From the prey to the predator, because they show the transfer of energy.
The variable that CHANGES AS A RESULT in an experiment
What is dependent variable
You are designing a cover to put on the windows of a car to help the inside stay cool. What color would you use to keep the interior coolest and why?
White would be the best because all the light is reflected rather than absorbed.
a path that one object takes around another object
What is revolution?
What is the reason for all investigations and experiments?
There is a QUESTION!

Mutualism, Commensalism and Parasitism
What is the difference between a food chain and a food web?
Food webs consist of many food chains. Both show the energy flow within an ecosystem.
Describe why sunflower petals appear yellow.
White light hits the petal. The yellow light is reflected to our eyes, all other colors are absorbed.
What does the Solar System consist of?
The Sun and everything that revolves around it (Sun, planets, asteroids, comets).
________ light can be separated into a rainbow of colors.
White light
Primary consumers are always _________.
Herbivores
Uses suns energy to make its own food.
What is a producer?
What breaks down dead organic matter in an ecosystem?
decomposers
The more mass an object has, the more force is needed to move it. T or F?
True
In a darkened room, a student shines a white light on a block. The block appears green. The student then shines a red light on the block. The block appears to be black. Why does the block appear to be black?
The red light is absorbed by the green block. No green light is able to be reflected.
