5.PS.3
Which form of energy is stored energy due to position?
Potential energy
Energy transferred through vibrations is called:
Sound energy
Eye color is an example of what type of trait?
Inherited trait
What are fossils?
Preserved remains or traces of organisms from the past.
What is the first step in the engineering design process?
Identify the problem
A stretched rubber band has what type of energy?
Elastic potential energy
Which transfers heat faster: metal or plastic? Why?
Metal, because it is a better conductor.
Riding a bicycle is what type of trait?
Learned behavior
What type of rock most commonly contains fossils?
Sedimentary rock
Why do engineers build prototypes?
To test and improve designs.
A moving bicycle has what type of energy?
Kinetic energy
Name the three ways heat transfers.
Conduction, convection, radiation
Why might offspring resemble their parents?
They inherit genetic information from their parents.
How can fossils provide evidence of environmental change?
They show organisms that lived in different climates or habitats.
A student builds a bridge model that collapses. What should be done next?
Redesign and improve based on test results.
When a flashlight is turned on, describe the energy transformation.
Chemical → electrical → light (and some heat)
Why does a metal spoon feel colder than a wooden spoon at the same temperature?
Metal conducts heat away from your hand faster.
Give one example of an inherited trait and one learned behavior in animals.
Inherited: Fur color
Learned: Hunting technique
If marine fossils are found on a mountain, what can be inferred?
The area was once underwater.
Why are constraints important in engineering problems?
Answer: They limit materials, cost, or time and guide the solution.
A roller coaster is at the top of a hill and then rolls down. Explain how potential and kinetic energy change.
At the top it has maximum potential energy. As it moves down, potential decreases and kinetic increases.
Explain how convection currents form in boiling water.
Warm water rises, cool water sinks, creating a circular movement.
Why can siblings look different even with the same parents?
They inherit different combinations of genes.
Why are fossils rare in igneous rock?
Heat from magma would destroy remains.
Explain why testing multiple designs leads to better solutions.
It allows comparison, identifies weaknesses, and improves efficiency and effectiveness.
