Well so far the data is NOT double the stuf. IF YOU MISSED CLASS TODAY you can check with a table mate for all the ranges OR you can just add this information to the data table: REGULAR OREO has an average stuf height of 2.7 mm; overall average mass is 11.5 grams; wafers alone are 8.2 grams; and the stuff is 3.2 grams. DOUBLE STUF OREO has an average stuf height of 4.5 mm; overall average mass is 14.5 grams; wafers alone are 8.6 grams; and the stuf is only 5.8 grams. Woa... that's a bummer and maybe even false advertising! You need to finish your analysis questions (back side of data table) and we will write our conclusion on Monday in class. Be safe this weekend with the forecasted storm!!!
Today we explored GOOD science methods with controlling variables (which we didn't do in Tootsie lab). IF YOU MISSED CLASS TODAY you missed out on discussion and practice in identifying variables. We also added VARIABLE, QUESTION, AND HYPOTHESIS to our notebook as notes (page 23). Watch the videos below to review the steps of the scientific method (our wheel) and a bit about variables. Tomorrow is fall fun day for 7th graders!
Today we analyzed our data and concluded that we still don't know how many licks it takes to get to the tootsie roll center of a tootsie pop! The experiment had too many variables! IF YOU MISSED CLASS TODAY you will need to write your analysis questions (page 21 in notebook... either copy question and then answer OR you can restate the question in your answers). Be sure to discuss YOUR results as well as the class average (check with a classmate) AND total Equinox averages in your conclusion work (614!). We have data from 88 lollipops with 54008 total licks!
Today we collected data to answer the question "How many licks does it take to get to the tootsie roll center of a tootsie pop?" Over the weekend you can let your tongue recover (who knew it would hurt so much from licking?!?!). IF YOU MISSED CLASS TODAY (or if you finally have a signed safety contract) you can get a tootsie pop from me on Monday when you return! We will continue with data analysis and conclusion work for this lab on Monday.
Today we assessed our understanding of the lab tools and safety. IF YOU MISSED CLASS TODAY you will need to take this SWYK when you get back either during lunch or homebase study hall (or if you don't have your safety contract in yet you will take it instead of science-ing). Next week we shall continue with our science work! Have a great weekend!!!
Tonight you need to study for your SWYK to Show What You Know about lab tools and how to use them safely.
IF YOU MISSED CLASS TODAY we did some reviewing of lab situations and what not to do! Be sure to spend some time reviewing the tools AND looking over safety rules.
Reminder that you will not be using notebooks for the SWYK!
USE THIS POWER POINT TO REVIEW
LOOK OVER THESE RULES FOR SAFETY IN THE SCIENCE LAB
LISTEN TO THIS SONG FOR SAFETY
Be ready for best success on the first academic grade of the year!!!
Some of you still have safety contracts or syllabus surveys to finish!
Today we created a study guide to learn our lab equipment. Tomorrow we will discuss how to safely use said lab equipment! IF YOU MISSED CLASS TODAY you can print THIS LIST OF EQUIPMENT and then take some time to look up what the items look like (you can also ask me for a picture page when you return to class). WATCH THIS POWERPOINT TO REVIEW EQUIPMENT. Some of you still need to have your parents sign the SAFETY CONTRACT. (some need to finish the SCIENCE SYLLABUS SURVEY as well!)
Most science pictures I post are found from assorted Facebook science pages... too numerous to cite specifically and downloaded for "just the right time"... sorry for the poor citation example I am setting...
