Lesson
2 - The Scientific Method
Answer this question in your science journal. Watch the Egg In A Bottle experiment.
That's right! It is called the "Scientific Method." If you follow the steps correctly, you should be able to repeat an experiment over and over while keeping the data and conclusion very similar. At the same time, if you have done a good job on a lab, anyone should be able to repeat the lab and come up with the same results. In this unit, you will be working on many varied activities. You will complete formal investigations, informal discoveries and technological challenges. Some of the activities will invite you to solve practical problems and others will provide you with opportunities to design your own experiments! Before we can get into the discovery of scientific facts and reasoning, we must start at the beginning! The best place to start is with a very important tool called the scientific method. The scientific method is a set of ideas or a procedure that scientists use to investigate things they want to understand. By using the method, you can be sure you're carrying out your project correctly. The scientific method allows you to investigate an experiment in a step-by-step method. Read through
the following process and then complete the "Egg In A Bottle"
experiment while completing each step of the "Scientific Method"
for this experiment. Problem: What are you going to solve in the lab? The problem or purpose explains exactly what you hope to accomplish in the investigation. Hypothesis: How do you think it is going to turn out? Use the facts you already know to come up with a guess that might really make sense. Materials and Apparatus: List what equipment you will need to complete the experiment. (Include diagrams of set up apparatus if required to do so in this section. Procedure: What you must do to complete the experiment. Write down the steps you need to follow. Data and Work: Include the tables, observations and work you did during the experiment. This section is where you keep very careful notes on everything you do and everything you find out. Be sure you write down or draw what really happened, even if it's not what you thought would happen. At the end, you look over all your data and think about it very hard. You think of the results of your procedure, or how everything turned out. Analysis Questions: You do not need to write out questions, but you must answer in sentences that include the question. Conclusion:
You must say what you found out during the lab. You figure out whether
your results agreed with your hypothesis or not. Put everything you observed
together and try to make some sense out of it. REMEMBER!! 1. Be neat. Your lab should be organized and easily readable. 2. Hand in a good copy. You can take a rough copy of data tables into the lab and then recopy for your hand-in report. 3. Hand in lab reports on time!
Good job! Now complete the "Egg Out Of The Bottle" experiment. Write up the lab and answer the questions. Once you have completed this lab, rewrite your good copy and prepare it for submission. This lab will be a practice evaluation. You will receive a practice mark and constructive feedback so you can improve on your labs.
