Matter & Chemical Reactions
What is the smallest unit of matter that still keeps the properties of an element?
What is-
an atom?
What is one way humans negatively impact the environment?
Pollution, deforestation, overfishing, fossil fuel use, etc.
What happens to kinetic energy when speed increases?
Kinetic Energy increases
What are the names of the three Schuyler Sisters?
Angelica, Eliza, and Peggy
By fate, one of Mrs. Potts' (Beauty and the Beast actress) horses has the same name of a popular Chicago Rapper/TV Personality. What is it?
Chance
What evidence shows that a chemical reaction has occurred? Name one.
Color change, gas produced, temperature change, precipitate formed, odor change, etc.
What is a divergent boundary?
A divergent boundary is a place where two tectonic plates move away from each other. As they separate, magma rises from below the Earth’s surface and can form new crust.
This process often creates features like mid-ocean ridges or rift valleys.
What is the phenomenon called when your body continues to stay in motion when a bus comes to a stop?
Inertia
What medium does sound travel fastest through?
Solids
Vernon Hills football team won the JV superbowl this year. Name the player from HMN who scored the most touchdowns in the game.
Everett Proctor
In a chemical reaction, other than mass, what does not change?
The total number of atoms.
Why are some natural resources unevenly distributed around Earth?
Because of past and current geologic processes
According to Newton's third law, every action has what?
An equal and opposite reaction.
¿A qué hora termina la escuela los miércoles?
Es la una y cincuenta de la tarde
The "Baby Shark Dance" went viral in 2016 with a very catchy tune. What is the name of the group that created the video?
Pinkfong
What law states that matter cannot be created or destroyed?
Law of Conservation of Mass
Which moon phase occurs during a solar eclipse?
A solar eclipse happens during a New Moon phase, when the Moon moves between Earth and the Sun and blocks some or all of the Sun’s light.
What are the two main factors in determining an objects acceleration?
The force applied to the object and the object's mass
What are the tiny hair-like structures in our ears that convert sound vibrations into electrical signals called?

How does the freezing point change when salt is added to roads in the winter?
When salt is added to roads in the winter, the freezing point of water decreases.
Pure water freezes at 0°C (32°F), but salt water freezes at a lower temperature. This allows ice to melt even when the air temperature is slightly below freezing.
How does a solenoid work?
A solenoid is a coil of wire that becomes an electromagnet when electric current flows through it. The magnetic field created pulls a metal rod (plunger) inside the coil, causing movement. This motion can be used to open valves, move switches, or power other mechanical actions.
Describe the formula for calculating kinetic energy?
KE = 1/2 mv^2
KE = kinetic energy (measured in joules)
m = mass of the object (in kilograms)
v = velocity or speed of the object (in meters per second)
What is the human hearing frequency range in Hertz?
20 Hz - 20,000 Hz
Mr. Leonardi and his son Lucas have the same middle name, what is it?
