AKA: Scientific Inquiry THE SCIENTIFIC METHOD
The scientific method is a series of steps to solve a problem or question You might hear this referred to as scientific inquiry. You and other scientists use the scientific method every day to answer a question or solve a problem. WHAT IS THE SCIENTIFIC METHOD?
An observation is when you use your senses to view the natural world. Example: Students observed that some frogs in their area had deformities. STEP 1: MAKE AN OBSERVATION
After you make observations, you become curious. A question will be based off of your observations and curiosity. Example: “Could pollution be causing the frog deformities?” STEP 2: ASK A QUESTION
A hypothesis is a possible answer to your question. A hypothesis is written in what we call an “If/then” statement. Example: If there is an increase in exposure to pollution, then some frog eggs will develop into deformed frogs. STEP 3: WRITE A HYPOTHESIS
An experiment is when you use specific materials and follow procedures to test your hypothesis. This is where you make more observations and collect data! Example: Students created 3 groups of frog eggs and exposed each group to pollution for different amounts of time. The number of deformed frogs which developed was recorded for data. STEP 4: PERFORM THE EXPERIMENT
Control Group/Variable – A group that receives no experimental treatment/the variable that doesn’t change. Independent variable – the one factor that is changed during an experiment. Dependent variable – the variable that changes because of the independent variable. EXPERIMENT CONTINUED.
STEP 5: INTERPRET THE DATA Gather all your results/data from your experiment and create a visual graphic (chart, graph, etc.) to represent them.
A conclusion is a summary of your experiment and what you have learned from it. Example: The pollution experiment supports the hypothesis that frog deformities can be caused by exposing the eggs to pollution. STEP 6: MAKE A CONCLUSION
Share your ideas, experiment, results, and conclusion with peers so they can learn. You can communicate by talking, writing, presenting, etc. STEP 7: COMMUNICATE YOUR RESULTS
