Daniel wants to test if Brand X paper towels are stronger than Brand Y when wet. To make the test fair, which towels should he use?
one from different brands but different sizes
one dry and one wet towel
one from each brand, same size and number
the same towel used for both brands
Once all data has been gathered in an experiment, what should a scientist do next?

conduct the test again with changes
analyze and interpret the results
Jacob is explaining how energy transfers from one organism to another in a food chain. Which method would most clearly show this energy flow?
a written paragraph
a labeled diagram
a descriptive sentence
a chart of values
A line graph shows rainfall over four days. Which type of chart can also be used to represent the same data clearly?
circle graph
histogram
bar graph

Anna performed an experiment using two trays with the same soil and seeds. She added fertilizer to only one tray. After a week, that tray had taller grass. What was likely her original hypothesis?
Fertilizer will result in taller grass growth.
The grass with fertilizer grew more.
The trays got the same amount of water.
The fertilizer caused faster growth.
After collecting and studying the data from an experiment, what should a scientist do next?
Pack up the lab materials
Describe the results and explain them
Begin a completely new experiment
Modify the procedure and start over
Sophie is exploring how different materials used for switches affect electric current. Which of the following would be a good hypothesis for her experiment?
A switch must be closed to complete a circuit.
The material used in the switch will change each trial.
If the switch is metal, then electricity will flow.
Cotton switches won't allow current through.
Carlos and Emma grew identical plants using different water types: tap, rain, pond, and mineral. After tracking plant growth, which conclusion might they reach based on the results?

Rainwater supported the best growth
Pond water was most effective
Mineral water was best for all plants

Nathan is testing different ways to join straws in a structure. He uses various connectors and tries to test all structures at the same time with different stacks of books. Why might his test be unreliable?
He must use different straw lengths
He should use different test materials on each one
He needs to test one structure at a time
He should weigh the books rather than count them

Emma and Carlos grew identical sunflowers using different types of water. After three weeks, they noticed some plants grew taller. What was the likely purpose of this investigation?
To compare types of fertilizer
To test soil conditions
To determine which water type supports plant growth best

Which plant is commonly used for healing purposes in medicine?
Cotton
Citrus
Aloe vera
Lavender
What do producers need to carry out photosynthesis?
Sunlight and nitrogen
Water and oxygen
Chlorophyll and carbon dioxide
Oxygen and nitrogen
Which process returns carbon dioxide to the atmosphere?
Transpiration
Precipitation
Respiration
Photosynthesis
Which formula best represents photosynthesis?
Glucose + oxygen → carbon dioxide + water
Carbon dioxide + water → glucose + oxygen
Oxygen + water → glucose + carbon dioxide
Glucose + carbon dioxide → oxygen + water
Which of the following is NOT an abiotic factor that can be polluted?
Air
Water
Soil
Sunlight
Lena squishes a foam ball into a pancake shape. What force is she applying?

Shear
During an experiment, Isaac noticed these signs: particles moving freely, weak attraction between them, and increased volume. What is most likely happening?
Solid being cooled
Liquid being heated
Gas being condensed
Liquid being frozen
Why does the red liquid inside a thermometer rise when it is placed in a hot liquid?
It expands as it warms
It shrinks from the heat
It begins to boil
It contracts under pressure
What happens to the particles in a substance when it is heated?
They stop moving
They move slower and contract
They move faster and spread apart
They become heavier and settle
What makes water unique compared to most other substances?
It doesn't change temperature easily
It expands when it freezes
It remains a liquid at all temperatures
It conducts electricity
How does heating or cooling affect the state of matter?
Heating slows down particles, forming solids
Cooling causes expansion of particles
Heating speeds particles up, causing melting or evaporation
Cooling creates more energy in particles
