Scientific Method
The format that a hypothesis should be written in.
What is an If...then...statement.
This is the area of chemistry that studies chemicals containing carbon.
What is organic chemistry?
Three roles that chemists play regarding energy.
What is conserve, produce and store?
The variable that you are manipulating and setting the parameters for in an experiment.
What is the independent (or manipulated) variable?
Chemistry that is done just for the knowledge sake.
The group that remains the same throughout the experiment.
What is the control group.
Branch of chemistry studying chemicals that do not contain carbon.
What is inorganic chemistry?
An area that chemists contribute to medicine in the development of this.
What is drug production?
The variable that you are measuring in an experiment.
What is the dependent (or responding) variable?
Chemistry that is done with a specific application or goal.
This is the group that is tested.
Branch of chemistry that studies the processes that take place in living organisms.
What is biochemistry?
This is one of the most popular pollutants determined by chemists that was banned from being used in paints, gas and plumbing pipes.
What is lead?
You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plant receives pure water. After a two week period the height is measured. The independent variable is:
What is the solution the plant is watered with?
What is the macroscopic world.
Another word for your dependent variable; what you are gathering during the experiment.
What is data?
The branch of chemistry that studies the composition of matter.
What is analytical chemistry?
Two ways that chemists have contributed to agriculture.
What is crop production and and productivity?
Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. Once tree is left outside in normal conditions. Height of the tree is measured once a week. The dependent variable is:
What is the height of the tree?
Blood cell, cheek cell and skin cell are all part of the ________________ world.
What is microscopic?
The step before forming a hypothesis in scientific method. (HINT: Not the step that requires using your senses).
What is create a question?
What is physical chemistry?
Chemists contribute to this part of society by analyzing samples from planets and the moon and determining their composition.
What is the universe?
Spending time with a cat or dog decreases the amount of stress someone is feeling and allows them to perform better on tests. The independent and dependent variables are:
What is amount of time spend with cats or dogs (independent) and performance on test (dependent)?
What is inference?
