Scientific Method
There is only one scientific method, and all scientists follow it in exactly the same way. True or False?
What is false?
Jasper watches the birds in his yard for two weeks to determine which of the two bird feeders they like best. He tells his teacher that this is an experiment, but it is actually this.
What is an observation?
All living things are made of one or more of these basic units of life.
What is a cell?
Variable on the X axis
What is independent variable?
This is the smallest level of biological organization that is considered living.
What is a cell?
Observations that are numerical
What is quaNtitative observations?
Ty wanted to find out which soil would help his plants grow best. He planted tomato plants in Soil A, pepper plants in Soil B, and squash plants in Soil C. Then he measured their height each day for five weeks. This is Ty's mistake.
What is he should have used the same type of plant.
Living things react to changes in their environment through this characteristic of life.
What is responding to stimuli?
Variable that is being measured
What is dependent variable?
A group of similar cells working together to perform a specific function forms this level of organization.
What is tissue?
A prediction about the answer you expect to get from an experiment is called this.
What is hypothesis?
Callie wants to test which model car will go down a ramp fastest. She releases model A and records the time it takes to travel to the bottom. She does the same with model B, and it gets there five seconds faster. She concludes that model B is the fastest car. This is her mistake.
What is she needs to do it more than once?
This characteristic of life allows organisms to produce offspring and pass genetic information to the next generation.
What is reproduction?
Variable that gets changed by the person doing the experiment
What is independent variable?
Multiple organs working together, such as the digestive system, make up this level of organization
What is organ system?
In this step we're trying to systematically test our hypothesis
What is experiment?
Dylan finds two types of varnish that are supposed to help keep the wood on his deck from fading in the sun. He decides to test them. He paints 10 boards with Vivid Varnish, and 10 boards with Valiant Varnish. He leaves 10 boards with no varnish at all. He leaves them in the sun for 4 weeks, and makes notes on their daily appearance. The 10 boards with no varnish would be his ________________ ______________.
What is control group?
Maintaining a stable internal environment, such as body temperature or water balance, is called this.
What is homeostasis?
Variable that is used to show that the results are actually caused by what is being tested; a baseline
What is a control variable?
All the populations of different species living and interacting in the same area make up this biological level.
What is a community?
The step of the Scientific Method accepts or rejects the hypothesis.
What is conclusion?
Sal gives his each of his strawberry plants 500 mL of water daily. He makes sure they get the same amount of sunlight and fertilizer. Twenty plants are in pots with potting soil. The other twenty are in pots with a sand and clay mixture. This is the tested variable for Sal's experiment.
What is soil type?
Over many generations, populations change and become better adapted to their environment through this process.
What is evolution?
Variable that changes in response to changes in the independent variable
What is dependent variable?
This is the largest level of biological organization and includes all ecosystems on Earth.
What is a biosphere?
