How to Keep Your Eyebrows
Before a lab experiment, strap these bad boys onto your head so you don't spend the afternoon blind and crying in the nurse's office.
Goggles
This unbalanced force is why someone drops their books in the hallway, or falls down the stairs.
Gravity
Your dirty laundry will remain happily on the floor forever until an outside force (usually a frustrated parent) acts upon it, proving this law.
Newton's First Law
You drag a heavy box right with 15 N of force, but carpet friction pulls left with 5 N. This is the net force doing the actual work.
10 N Right
This component of CER is your mic-drop moment—the direct, bold statement that answers the initial question.
Claim
The person who needs to know immediately if a beaker shatters, even if it was "totally an accident."
Teacher
While screaming on a rollercoaster, you have the most speed at what point of the ride?
Bottom
The equation to tell how fast something is going, how much matter it has, and how much force was used for Newton's Second Law.
F = m x a
The slick ice has minimal amounts of ______ friction against a hockey puck.
Sliding
Using your five senses or lab gear to catch reality in the act—no guessing allowed.
Observation
The mandatory hairstyle choice for long hair unless you want your locks transformed into a torch.
Ponytail
A falling raindrop has a lot of _______ energy.
Kinetic
You have a 4 kg ball that accelerates at 5 m/s², what is the force?
20 N
When all opposing forces on you cancel out completely, you reach this serene state where net force is zero and nothing moves.
Balance
Raw numbers, lab photos, and cold hard data fill this role in your scientific argument, because "just trust me bro" doesn't count.
Evidence
The emergency water fountain where you get to spend 15 awkward minutes staring directly down if chemicals hit your eyes.
Eyewash Station
Pulling back an archer’s bow string stores this specific strain of energy right before you release the arrow and hope for a bullseye.
Potential Energy
When a rocket blast pushes down on the launchpad, the launchpad pushes up on the rocket. This fiery spectacle is brought to you by this law.
Newton's Third Law
Getting a heavy couch to start moving requires more force than keeping it moving, because this type of friction is a bigger bully that wants to stay still.
Static Friction
When you're wrapping up your findings into a final, comprehensive paragraph that sums up your results.
Conclusion/Summary
Gently fanning chemical fumes toward your nose instead of taking a deep, regrettable snort.
Wafting
A reckless driver forgets to wear their seatbelt and takes a quick trip out the windshield due to ______ since their body is still going 80mph.
Inertia
If a dog accelerates at 10 m/s² while pushing at 50 N, how much mass does the dog have?
5 kg
An evenly matched tug-of-war will have what net force?
This part of CER connects your facts to your claim, using scientific principles to explain why your evidence actually matters.
