Descriptions

100

Step that begins the scientific method and states what you are trying to solve/do

Question/Problem

200

Step that you look at the results or the information gathered from the experiment and determine if it is good and if it supports your hypothesis

Analyze Data

300

Step in which you must state what you think in an "If-then", "If-then-because", or "will-because" statement

Hypothesis

400

Step in which you are looking up what other's have found out and find more information about the topic you are experimenting (remember, it must be relevant to your experiment)

Research

500

Step in which you are wrapping up you experiment by stating whether your hypothesis was correct, restate your results, reflect on your research, discuss any problems or issues found in your experiment, and what you would like to change or try next time

Experiment: You will rub 1 tsp of different liquids on a coffee stain and will leave for 5 minutes.  You will then rinse the stain and will see how much stain is left behind.

Question: What is the independent variable?

Liquids you are testing to remove the stain

200

Experiment: You take 3 bean plants and measure their height.  You will then water them with 3 different amounts of water a day: 2 Tbsp, 1/2 cup, and 1 cup.  You do this for 3 weeks and will record the height of the plants at the end of each week.

Question: What is the dependent variable?

Height of the plant

300

Experiment:  You will make 3 different paper airplane designs out of computer paper.  You will then fly them each 3 times and measure the distance they go.

Question: What variable does the computer paper represent?

Constant/control

400

Experiment: You take 2 ml of 4 different cleaning agents and let a dirty penny sit in them for 20 minutes.  Take the pennies out of the cleaning solution and remove the cleaning solution. Record observations on how clean the penny is.

Question: What is the dependent variable?

How clean the penny is

500

Experiment: You will take 2 bouncy balls and soak one in boiling water for 10 minutes and leave the other in a box of dry ice for 10 minutes.  You will then remove the bouncy balls and drop them from a height of 1 meter.  Record how high the ball bounces.

Question: What is the dependent variable?

Bounce of the ball
