Physical Science
This force causes an object to speed up, slow down, or change direction.
An unbalanced force.
The two basic needs help plants grow and survive.
Water and sunlight.
Weather.
This is the first step in engineering, where you identify a problem to solve.
Defining the problem.
This skill involves carefully using your sense to gather information.
Observing.
This property of matter describes how something feels, like smooth or rough.
Texture.
This term describes how living things depend on each other and their environment.
Interdependent relationships.
Weather forecast.
These limit what you can use when designing a solution, like time or materials.
Constraints.
This is when scientists explain results using facts and data.
Constructing explanations.
This form of energyu travels in waves and allows us to hear sounds.
Sound energy.
These are characteristics passed from parents to offspring.
Traits.
This slow process breaks down rocks over time.
Weathering.
This is a drawing or physical example used to show how something works.
A model.
This is when scientists look for patterns and relationships in data.
Analyzing data.
These tiny particles make up all matter but are too small to be seen.
Particles.
These four stages describe the life cycle of all organisms.
Birth, growth, reproduction, and death.
This star appears brighter than others because it is closest to Earth.
Sun
This type of test controls variables to ensure accurate results.
Fair test.
This is when scientists share findings with others.
Communicating information.
This happens when forces are equal and do not change an object's motion.
Balanced forces.
Plants get most of the materials they need for growth from these two sources.
Air and water
These four systems interact to shape Earth: geosphere, hydrosphere, and atmosphere, and this one...
Biosphere
This process involves creating, testing, and improving solutions to problems.
Engineering design process.
This is the process of asking questions, testing ideas, and drawing conclusions.
Scientific investigation.
