the specific plan to test an idea (the steps for an investigation)
scientific method
the states of matter
solid, liquid, gas
1. attracts pollinators
2. has chlorophyll and is where plants make their food
3. transports water and nutrients to the rest of the plant
4. absorbs water and nutrients from the ground
1. flower
2. leaves
3. stem
4. roots
1. makes it own food using energy from the sun
2. consumes (eats) other living things for food
3. breaks down dead organisms or waste, returns nutrients back to the soil
1. producer
2. consumer
3. decomposer
this cannot be created or destroyed; only transformed or transferred
energy
a prediction that uses what you already know about a topic
hypothesis
the smallest particle matter is made of
atoms
sunlight, water, nutrients, carbon dioxide are the ______ of photosynthesis.
1. a consumer that only eats plants
2. a consumer that eats both plants and meat
3. a consumer that only eats meat
1. herbivore
2. omnivore
3. carnivore
1. stored energy
2. the energy of motion
1. potential energy
2. kinetic energy
the variable that the scientist changes
independent variable
the thing that causes phase changes
thermal energy
oxygen and sugar (glucose) are the ______ of photosynthesis
products
ways to organize living systems
1. one living thing
2. a group of the same kind of living things
3. different populations living together in the same place.
4. all of the living and nonliving things interacting with each other
1. organism
2. population
3. community
4. ecosystem
a force that resists (works against) motion
friction
the variable that stays the same
constant
a combination of two or more substances that do not lose their identifying characteristics when combined
mixture
The two ways plants can reproduce
seeds and spores
the role or job of an organism in its ecosystem; these can change throughout an organism's life cycle
niche
when two objects knock into each other that causes a change in motion (speed/direction) and a transfer of energy
collision
the data/results
the variable the scientist measures/observes
dependent variable
a special kind of mixture where a substance dissolved in another substance
solution
1. the part of the plant that attracts pollinators
2. the part pollinators pick up pollen from
3. the part of the plant that pollinators will drop pollen into to help pollinate the plant
1. A
2. C
3. B
1. organism that has a skeleton with a backbone inside its body
2. organism that DOES NOT have a skeleton with a backbone in its body
1. vertebrate
2. invertebrate
1. equal forces in opposite directions that cause and object remain in place
2. unequal forces where there is a difference in strength and/or direction of the forces. This causes an object to move.
1. balanced forces
2. unbalanced forces
