Today students finished the lab: Density of different sizes and answered the questions for the lab. We also compared data that was collected. The last thing we did today was set up a little for the lab we will be doing tomorrow. The information attached went on page 17 in your science notebook.

Today we started a lab: Density of different sizes. Attached below is the information students wrote and some of the data we collected. (You can copy this (or print it and glue it) on page 15 in your notebook. 1. You need to write a hypothesis answering what you think the answer to the question will be. *I think.... because..... 2. You need to calculate the density for each object. 3. You need to answer the questions at the bottom of the page on page 16 in your science notebook.
Today we are going to update our sunrise/sunset data for the last time and will find out when the equinox really was (attached below). Next, we are going to go over the density phet simulation sheet that was completed on Friday (and give time for some people to finish it). Last, students will finish the Galileo- on the shoulders of giants video.
Today students are going to the library to complete a Density Phet simulation. The sheet needed is attached below (2 pages). *Important: You need to subtract 100 from each of the volume amounts in each section. For example, if it says 105.00 L you should use 5.0 L for the volume instead. If it says 110.00 L you should use 10.0 L; if it says 102.5 L, you should use 2.50 L, etc. I am also attaching a video showing how to navigate the simulation for each section of the simulation. Please end at 4:40. Remember, Density = Mass/Volume. Have a great weekend!
Today students took notes on density and did practice problems, which are attached below. They also watched a video on density, which is included below.
Today students are learning about density. Density is equal to mass divided by volume.
Density = mass volume We did an example problem and then students did a lab where they measured mass and volume and then calculated the density of the two objects. Mass = 5.52g volume = 2ml Density = 5.52g/2ml = 2.76 g/ml Today we are updating the sunrise/sunset data (attached below). Then we are doing Part D of the Volume lab (continued from the volume lab last week). If you are absent you will be excused from this work as the lab can't be replicated at home. A picture below shows our results from the lab we are doing today.
Today students are going to the writing center to access Google Classroom (physical science). If you are absent, you can go to my google classroom. You will be writing a CEAL paragraph explaining your fall equinox prediction (A google doc has been assigned to you and will have a guide at the top). Once you complete that you will fill out a survey in a google form.
Today students learned why we have been tracking the sunrise and sunset times. We talked about what an equinox is and took the following notes: Equinox: the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are (nearly) of equal length (Spring equinox is typically March 20). The line of best fit is an educated guess about where a linear equation might fall in a set of data plotted on a scatter plot. Then, I walked students through how to make a scatter plot/line of best fit to predict when the Fall/Autumnal equinox will fall (not the date they have on the calendar). Templates and sunrise/sunset data are attached below. An example of a graph I made is also attached (I used the amount of daylight and days in September to make the graph). The video we watched is also linked below.
Today students learned about volume. Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. The notes for the lab we did are attached below.
