- Observation: information gathered using one or more of your 5 senses
- Qualitative Observation: deals with descriptions that can be observed but not measured (ex. color, texture, smell)
- Quantitative Observation: on observation dealing with numbers that can be measured (ex. length, time, temperature)
- Inference: an interpretation of one or more observations
Today, in class, we discussed the difference between observation and inference. We copied down the following notes on the note sheet that Mrs. Oyer passed out in class:

Today, the class completed a lab using M&Ms! Working with a partner, we predicted how many of each color of M&Ms were in a package and then, opened up the package to see the actual number of M&Ms. (Of course, after we were done counting the M&Ms, we had to sample a few!) Then, we practiced graphing the data, and designed an experiment to answer the questions--do the different color M&Ms taste different? Overall, it was a great Friday activity. If the students did not finish their labs in class, then they will be homework are due on Monday. This week, we have been working on making graphs in science class. Monday and Tuesday, we made bar graphs and line graphs by hand. Wednesday and Thursday will be spent making pie, line and bar graphs on the computer using Microsoft Excel. If you have Microsoft Excel at home, practice your graph-making skills that we learned today in class!
*If you have any missing work (names are posted on my white board), make sure to get everything turned into me as soon as possible! Today was a day of firsts in science class! We took our first quiz over the scientific method and completed our first lab--and everyone survived :) The lab we completed was called The Drop Print lab, and student worked in pairs to take data on what happens to the width of a drop of water when you dropped it from different heights. There were 2 questions on the lab that are homework if they were not finished in class. Tomorrow, we are doing another lab--it should be a fun Friday!
Tomorrow is the first science quiz over the scientific method! The class checked over their study guides and I passed out a sample experiment to study from. Remember, for the quiz there will be a problem that you will have to solve using the scientific method. The best way to study is to choose any problem and practice solving it with the scientific method!
The homework tonight is to finish filling out the scientific method flip chart that we worked on in class. You can pick any problem to solve--just make sure it can be tested with an experiment. Below are the directions: Today, in class, we finished the notes over the scientific method that the class started on Friday. We then watched a short video clip of Mythbusters, and discussed how the Mythbusters scientists used the scientific method to discover if the human voice is actually able to break glass (watch the video below, it's pretty cool!). The homework today is to finish writing a detective story titled "The Case of the Polluted Stream". Below are the directions to the story--remember the story needs to be a full page long! These are the steps of the scientific method. 1. Choose, or state the problem. 2. Research the problem. 3. Develop a hypothesis. 4. Design an experiment. 5. Test your hypothesis. 6. Organize your data. 7. Draw conclusions. Use these steps to write a detective story. The detective is you. In this story, you should solve the case by following the steps of the scientific method. Everyone loves a secluded stream, with clear water and overhanging trees. That was what brought Jackie Shavers to Clear Creek on Thursday, July 2, at seven o’ clock in the morning. He often fished in Clear Creek at that time of day, but on this day, Shavers was horrified to find the creek was full of soap suds—his lovely stream had been polluted the night before. At least, that is what he thought. Shavers ran back to his house and called the police station. The sergeant put me on the case. The first thing I did was to head for Clear Creek. Finish the story of the polluted stream on another sheet of paper. Use your imagination for the details. Be sure to use the steps of the scientific method to solve the case. Today, we began our unit over the scientific method. Students took notes (which can be found in the note section of my website), as well as create their own scientific method flow chart showing the steps of the scientific method. Some students finished this in class, but if it was not finish, it will be homework over the weekend. Students must have a finished flow chart with all of the steps of the scientific method, and it must be colored and neat! Next week, we will begin pef
Today, we learned about organisms and what they need to survive. The assignment for today was to create your own organisms. The following things need to be included for the assignment:
