7th Grade Math
In math, a straight line is measures how many degrees?
180 degrees
an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity (same speed and direction) unless acted upon by a net external force.
What is Newtons First Law of Motion
What type of triangle has all equal sides?
Equilateral
What is Geographic scale and what type of measure is it
Unit: Kilometers (km)
Used for very large sizes. Continents and people are on entirely different scales because a person is vastly smaller than a continent. We use kilometers to measure distances between cities like Los Angeles and New York.
YIKESS!

Dmitry Mendeleev and his pedictive blanks in his periodic table, what are they?
He left strategic blank spaces for elements that did not fit the column properties, successfully predicting the existence and atomic masses of undiscovered elements.
A student walks 3 meters east, then 5 meters west then 8 meters east then 10 meters West. What is their final displacement? Remember to include direction
What is 4 meters west?
Formed by two or more different elements that are chemically bonded together.
What does PEMDAS stand for?
Parentheses, exponent, multiply/divide, add/subtract
When liquid water is in a solid form what is it?

Name the steps to solving Scientific notation.
1. Create a Number Between 1 and 10
Move the decimal point until you have a single non-zero digit to its left (e.g., 32,500 becomes 3.25).
2. Count the Decimal Places
Count how many places the decimal moved. This number determines the value of the exponent.
3. Determine the Sign of the Exponent
If the original number is greater than 1, the exponent is positive. If it is less than 1, the exponent is negative.
The Scanning Tunneling Microscope and how it works?
The Braille Analogy
The probe moves across a surface. Closer to an atom, electric current increases; farther away, it decreases. Scientists can map the surface shape precisely, similar to feeling braille dots.

The car travels 200 km in 2 hours and then 100 km in 1 hour. What is the average speed?
What are the three main structures of the atoms? (bonus: what is the center of an atom called?---100pt)
The basic atom consists of protons (positive charge), neutrons (no charge), and electrons (negative charge). The nucleus contains protons and neutrons, while electrons circle along orbital paths.
What is 1/2 + 1/3=
