A class wants to build a bridge using popsicle sticks and glue. Which factor should they consider when choosing the design?
The color of the popsicle sticks
The bridge's ability to hold weight
The length of each popsicle stick
How much glue is left in the bottle
Which of the following designs would best help a solar car move faster?
A heavier body structure
Larger solar panels to capture more sunlight
Smaller wheels for less friction
Thicker tires to grip the road
When comparing two paper airplane designs, what should you consider?
The color of the paper used
How far each airplane flies
The cost of the paper
The brand of paper used
Students are designing a boat to hold marbles. What should they compare between different designs?
How much paint they use on the boat
How many marbles the boat can hold before sinking
The number of friends who like the boat design
The size of the marbles
Which would be the best way to improve a model bridge?
Make it look more colorful
Test if using stronger materials helps it hold more weight
Use fewer materials to save money
Make the bridge taller
When testing a paper airplane design, which factor should remain constant?
The person throwing the airplane
The time of day the test is conducted
The way the paper is folded
The color of the airplane
Which is the best way to carry out a fair test on a model boat's performance?
Test each boat in different water conditions
Use the same amount of water and measure how long each boat floats
Test boats made from different materials and compare them
Change all variables at once to see the overall effect
A group wants to test which plant grows best under different lights. What is one variable they should control?
The type of soil used
The number of leaves on each plant
The color of the pots
The day they plant the seeds
Why is it important to control variables in an experiment?
To make sure the experiment is fun
To know which factor caused the change in the results
To save time during the experiment
To ensure everyone participates
If a prototype fails during testing, what should you do?
Start over without making any notes
Identify what caused the failure and think of ways to improve it
Throw the model away
Assume the design is perfect
What main material do plants get from the air to help them grow?
Soil
Carbon dioxide
Sunlight
Oxygen
How do plants use water in their growth process?
Water helps plants change sunlight into energy
Water makes the leaves green
Water keeps the roots warm
Water provides food for the soil
Which of the following is NOT a main source of materials for plant growth?
Sunlight
Air
Soil nutrients
Rocks
When a plant takes in carbon dioxide, what does it do with it?
Turns it into oxygen
Stores it in the roots
Uses it to grow leaves and stems
Releases it into the soil
Which statement supports the idea that plants get their materials mainly from air and water?
Plants need fertilizer to grow
Plants absorb sunlight for energy
Plants produce food through photosynthesis using water and carbon dioxide
Plants grow best in rich soil
What role do decomposers play in an ecosystem?
They produce energy for the sun
They break down dead organisms and recycle nutrients
They create oxygen for plants
They eat plants and produce waste
How does matter move between plants and animals in an ecosystem?
Animals eat plants to get energy
Plants absorb nutrients from animals
Plants and animals share the same water
Matter does not move between them
Which best describes how a model could show the movement of matter?
Using arrows to show how nutrients flow from soil to plants to animals
Drawing a straight line from the sun to plants
Coloring plants and animals the same color
Showing a diagram of how animals breathe
What happens to a plant when it dies in an ecosystem?
It turns into a rock
Decomposers break it down, returning nutrients to the soil
It disappears without a trace
Animals carry it away
Which statement best describes how energy moves through an ecosystem?
It flows in one direction from the sun to plants to animals
It is created by plants and animals
It stays in the soil
It moves in circles between animals and decomposers
What direction does gravity pull objects on Earth?
Upward
To the left
Downward
Sideways
Which of the following demonstrates gravity in action?
A balloon floating in the air
A ball falling from a table to the floor
A leaf flying upward in the wind
A car moving forward on a road
How would you support the argument that gravity pulls objects toward Earth?
By dropping different objects and observing they all fall down
By watching a bird fly
By explaining how boats float
By comparing the speed of moving cars
If there were no gravity, what would happen to a thrown ball?
It would fall to the ground quickly
It would continue moving in a straight line forever
It would stop in mid-air
It would spin in circles
Which experiment would best show the effects of gravity?
Dropping two objects of different weights to see if they both fall
Rolling a ball on the floor and measuring the distance
Throwing a paper airplane and timing its flight
Watching water evaporate in the sun
