Today we are doing our first formal lab. Our question/purpose to answer in this lab it “how many drop of water can I get on the top of a dime?”. To answer this question we will use the formal lab template provided below. Also, here is a video discussing formal lab write-up procedures (just in case you had to miss class).
Today we watched some videos on the Earth’s crust that explain how convection moves the tectonic plates in Tectonic Theory. Check out the links below. Then go to the Quizlet link to study the vocabulary related to the lesson. Also, there is a link to the handouts from class.
Today we took notes on the 3 types of rocks. Watch the video above to get some notes of your own. If you need some help there are some notes linked below that Mr. Ewert took during class (however, remember that taking your own notes is by far the best practice so don’t just print these).
Today we are discussing air pressure. We will be observing a few demonstrations and then attempting to explain the Science behind them.
First: review the video below that we tried a few weeks ago. Do you remember how to explain it?
Second: Take a look at the expanding air experiment below. But, be sure that you have your mini-lab ready first. This means that you need to have a piece of lined paper with the date, your name, Science, and Mr. Ewert in the top right hand corner. The title is “Balloon and Bottle Experiment”. You need to have the question, “what will happen to the bottle with the balloon on it when the bottle is heated?”. For materials and procedure just write, “see class blog post”. Make absolute sure that your hypothesis is detailed and completed before watching the video.
Third: Complete a mini lab for the final demonstration. This one is called “Egg and Bottle Experiment”.
Today we boiled water and took temperature readings each minute to observe how the two interact. When we graphed our results we found that there is a “curve” whenever there is a change of state. See our results below and watch the video that explain this concept.
Here is a copy of the assignment in class. Attach this to your existing formal lab. Use your lab template if you need.
