Today we discovered that our tootsie lab was not a great scientific lab. We had too many variables we didn't control for. Tonight we have a worksheet on variables (did you forget yours? PRINT ME) Remember you have definitions in your glossary for the types of variables your worksheet discusses (independent, dependent, and controls). Tomorrow we grade the worksheet and continue our discussion of variables (and questions and hypotheses and procedure)! Watch the video below for help in understanding variables! It's helpful!!!
Today we investigated the age old question of "How many licks does it take to get to the tootsie roll center of a tootsie pop?" Tomorrow we shall compile all the licks, do some data analysis, and then draw conclusions as to how many licks it DOES take to get to the tootsie roll center of the tootsie pop.
Tonight you DO NOT have to write your conclusion (we thought yesterday during planner time).
IF you would like to investigate about Tootsie Pops you might want to EXPLORE THIS SITE.
Today we discussed the importance of observations, data collection, repeating trials, inferences, etc... Tomorrow we shall ask a very important question (and better still find the answer... I hope!).
Tonight will be cool for sure in the skies... go watch!! CLICK FOR DETAILS!
Today is free entrance into the park for Public Lands Day... GO!!! Yesterday we discussed some of the Native American stories to explain the beginnings of Glacier. Go explore today and draw your own conclusions as to the beginnings of such beauty! Next week we will discuss procedures and scientific investigation. Fun stuff!
Today we explained what equipment to use and the safety steps to follow for lab investigations. Tomorrow we shall discuss data from the SWYK and discuss Native American contributions to science understanding!
GET YOUR SAFETY CONTRACTS SIGNED!!! You don't want to miss out on next week's investigations!
Today we reviewed the lab equipment and discussed safety rules. IF you did not get a signature on the safety contract DO SO TONIGHT (forgot it? PRINT THIS)... Tomorrow we SWYK on lab equipment. Review THIS!
Today we discussed data analysis (and visited with Tim and Moby of Brainpop). We also discussed the errors in our Friday graphs (remember IF you missed school last Friday you have data to gather from ME). Tonight you can go for a "4" on graphing using the data from our Starburst post it graph. You will need to calculate and graph the percentage of students who like each of the Original Starburst flavors. 23 like cherry; 19 chose orange; 15 were lemon lovers; 41 smartly chose strawberry, and 7 individuals don't like Starbursts!
Today we discussed good graphs and bad graphs and collected some more data TO graph! This weekend you need to finish your SWYK of the birthday data (if you didn't get it done in class). IF you were absent today you will need to check in with ME upon your return either before school, during homebase, at lunch, or after school. I have your data and will give you the details you need. Monday we continue with data analysis!
Today we discussed our Glacier Park data and wrote some REFLECTION QUESTIONS (put on page 10). Next we took NOTES ON HOW TO GRAPH DATA (print the page for your notebook p. 13). Tonight you need to graph boys vs. girls for your class (if you were absent you will need to visit with me to get the data for your class OR call a classmate for the data). Tomorrow we continue discussing graphing. Yes... it is very exciting!!!
