Today we analyzed our Tootsie results and made the conclusion that we still don't know how many licks despite having 96 lickers and 56448 total licks done. We didn't control variables in the experiment to draw a scientific conclusion! IF you missed class today (or broke your arm and can't write well) you can PRINT THESE NOTES. We will continue the discussion of variables and doing good scientific problem solving next week!
Today we used the scientific method to get an answer to the age old question of how many licks does it take to get to the tootsie roll center of a tootsie pop. IF YOU MISSED TODAY: come get a lab sheet AND a tootsie from me so you can weigh in on the analysis and conclusion. Tomorrow we shall discuss just how accurate this investigation was (or wasn't). Tonight let your tongues relax ... no analysis questions after all! We have data from 84 lickers thus far with a total of 45743 licks to the center ... we still have more data to analyze!
Today is a day to mix and mingle with the other teams of awesome 7th graders! Tomorrow back to science!!!
Today we practiced skills used in scientific problem solving: observation and inferences. We discovered knowing the question BEFORE making observations sure helps! We also discovered the importance of repeating trials instead of one and done experimentation. Tomorrow is FALL FUN DAY and then back to experimentation with the scientific method on Thursday. Time to investigate important questions.
Today we analyzed the similarities and differences of the scientific method, scientific inquiry, scientific problem solving, scientific investigation, and the scientific process. Turns out it's all the same thing! Slightly different number of steps maybe, but all have common expectations: observation, hypothesis, data collection and analysis, conclusions ... same but different but the same! The next few weeks we shall practice our skills of science. Be sure to have SAFETY CONTRACT signed and delivered tomorrow! Grrrrrrrr...
Today we reviewed our field trip data. Some of us didn't fill in all the information we need to truly analyze our observations, so we took some time to clean up missing names, headings, and population totals. We shall use the data for more analysis during science and math. The Kootenai used Apgar as a mid-winter camp AND they call the Apgar area "Ya kit Haquitnamki" which means "The Place Where They Dance". We will explore many more ways the natives of Montana have contributed to science this year! IF YOU WERE ABSENT TODAY: you will need to answer THESE QUESTIONS ON PAGE 16 OF YOUR NOTEBOOK!!!
Can you believe how NO RAIN FELL during our field trip!!! YESSSS!!! Great day for data ... rest up tonight!
Rain rain GO AWAY!!! Soggy first day of fall ... but a day in Glacier Park still is an awesome day to have!!!
Tomorrow we head into Glacier to observe succession. We will venture into areas burned 13 years ago and compare the species of trees (and overall community of organisms) with areas burned nearly 80 years ago. How fun to actually use science skills in the field! It looks like rain so make sure you are all set and ready!

Today we reviewed succession (and added this term to our glossary) and learned how to use a dichotomous key to identify tree species. Tomorrow we wrap up background prep for the field trip and Thursday we go!
Remember you will need to pack a lunch for Thursday, bring water, AND plan for rain! Safety contract still?

Today we started to discuss just what will we do in Glacier on Thursday?! We shall explore succession of tree species after a fire disturbance. Tomorrow we will learn how to key out tree species. Wednesday we practice the method of data collection, and Thursday we hope not to get too soggy as we venture into the park!!!
If you missed school today (or last Friday) you will need to setup a lunch/after school time to take your SWYK for safety and lab equipment. Some of you still need SAFETY CONTRACTS signed ... please do that tonight!
Today we took our SWYK to Show What We Know of the steps, tools, and safety in our science class. This weekend a few of you still need to get your SAFETY CONTRACTS signed. Please do! Next week prep for the field trip! IF YOU MISSED CLASS TODAY... you have a SWYK to make up. Plan for lunch or after school.
