100
This is the diameter of a circle with a radius of 5.
What is 10?
100
These angles add up to 90o.
What are complementary angles?
100
This is an educated guess based on prior knowledge and/or observation.
What is a hypothesis?
100
Plants release this element as waste.
What is Oxygen?
200
This is the ratio of the circumference of a circle to its diameter.
What is
pi ?
200
These are two non-adjacent angles formed by intersecting lines. In this case <1 and <3, for example.
What are vertical angles?
200
In order to be a valid hypothesis, it must be this.
What is testable?
200
This cell part is responsible for capturing solar energy for a plant?
What is chloroplast?
300
This is a commonly used numerical approximation for
pi.
What is 3.14?
300
These congruent angles on parallel lines made by a shared transversal, map on to one another.
What are corresponding angles?
300
When testing a hypothesis, a scientist tries to ______ the hypothesis.
What is disprove?
300
Photosynthesis requires these two molecules.
What are Cardon Dioxide and Water?
400
A pizza is advertised as containing 250 square inches of pizza.
This is roughly the diameter.
What is about 18 inches?
Since the area of a circle (pizza) is
pir^2
Divide 250 by 3 (pi-ish), which is a little more than 80, let's say 81. which leaves you with radius squared to solve. The square root of 81 is 9 so radius is 9. So diameter, is roughly - 18.

The Triangle Sum Theorem says this.
What is, "All interior angles of a triangle add up to 180o"?
400
This is the measure of the extent to which two variables are related.
What is correlation?
400
The overall purpose of the light-dependent reactions is to convert light energy into this.
What is chemical energy?
500
This is the shaded region's area.
What is ≈ 69.53 square meters?
Side length is 18. Therefore radius, which must start at the center is 9.
Square area = 18 x 18 = 324
Circle area =
pi (9)^2
Square area minus circle area = shaded area... 324 – 81π 69.53 square meters.
500
This is the measure of the red angle.
What is 50o?
500
This can represent a complex system. We use these because they can be manipulated more easily than the system.
What are models?
500
Plants get water from these.
What are roots?
