Earth and Space
The center of our solar system
what is the sun?
animals that only eat plants
what are herbivores?
matter takes up space and has this
what is mass?
This simple machine reduces the effort needed to lift or move heavy objects using a wheel and rope
what is a pulley?
Information collected during an experiment
what is data?
scientist who studies weather
What is a meteorologist?
shows how energy moves from one organism to the other
what is a food chain?
This happens when a push or pull changes an object’s motion
what is a force?
This step in the design process involves deciding what worked and what did not after testing a solution
what is evaluation?
Using your senses to gather information
what is observation?
What is rain, snow, sleet and hail?
If a new species is introduced and competes for the same resources, this is the most likely outcome for the original species
what is decrease in population size?
Energy that travels in waves and allows us to see
what is light energy?
After testing a design, engineers often do this to improve their solution.
what is redesign?
A prediction based on evidence
what is a hypothesis?
What causes Earth's seasons?
What is Earth's tilt on its axis?
A change in a species over many generations
what is evolution?
used to represent matter because atoms are too small to see directly
what is a scientific model?
This type of simple machine is a straight or slanted surface that makes moving objects easier.
what is an inclined plane?
This is when you use information from observations to explain what might be happening.
what is an inference?
What happens when the moon moves between the sun and earth?
What is a solar eclipse?
An animal changing to survive better in its environment
what is adapting/ adaptation?
This explains why matter keeps its total mass even when it changes state in a model.
what is particles are not created or destroyed?
If a prototype fails during testing, this is the most appropriate engineering response.
what is revise and improve the design?
This is what scientists do when they use results from an experiment to support or reject their hypothesis
what is draw a conclusion?
