3. Hypothesis
4. Experiment
5. Analyze Results
6. Conclusion
What is Inertia?
The natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless acted upon by a force.
This scientific tool is used for precisely measuring mass.
Triple-Beam Balance
Four ways force affects motion.
- Start
- Stop
- Change Motion
- Change Direction
Give one example of each symbiotic relationship:
- Mutualism
- Commensalism
- Parasitism
(Answers will vary)
What is a Qualitative Observation and Quantitative Observation?
Qualitative: Non-Countable Observation (i.e. Color, smell, etc.)
Quantitative: Countable Observation (How much?, How many?, etc.)
*DAILY DOUBLE (800 POINTS)*
What is Momentum?
(Hint: It's an equation)
Mass x Velocity
This scientific tool is used for containing and observing the growth of bacteria or fungi.
(Hint: It's circular)
Petri Dish
What are the four fundamental components of a habitat?
-Food
-Water
-Shelter
-Space
Properly label this Food Chain with Predator, Prey, Consumer, and Producer.
Sun --> Grass --> Mouse --> Cat
Grass = Producer
Mouse = Prey and Consumer
Cat: Consumer and Predator

(Hint: Apples)
Gravity
This scientific tool measures volume.
Graduated Cylinder
How two words do you need within the structure of a Hypothesis?
- If______, then______.
What is an Invasive Species?
Non-native organisms (plants, animals, microbes) that spread aggressively in a new ecosystem, causing harm to the environment, economy, or human health by outcompeting natives, disrupting habitats, and reducing biodiversity, often thriving due to a lack of natural predators.
This variable is changed in a Controlled Experiment.
Independent Variable.
What force resists motion?
(Hint: It can create heat)
Friction
This scientific tool keeps liquids from spilling out of test tubes and flasks.
Rubber Stopper (or a Stopper)
What are Kinetic and Potential Energy?
Kinetic Energy = Energy of Motion (Arrow being shot)
Potential Energy = Stored Energy (Arrow being drawn)
Name four types of Ecosystems.
Forests, Grasslands, Deserts, Tundras, Mountains, Ocean, Marine, Savannahs, etc.
(Answers will vary)
This is the variable that stays the same.
Controlled Variable (Constant).
This thing is any push or pull from one object to another.
Force(s).
This scientific tool allows us to see small objects up close.
