Tonight is the night to wrap up your THIEVES.
Some of you feel good about the summary (introduction) work you have already done. Some of you want to add more and need to cite the textbook. Some of you chose to bring home a text to finish your End of section questions. Some of you didn't need to because the work was done already today. Some of you may still need to borrow the book for the long weekend since there won't be class time for working on Wednesday.
Choose well my little grasshoppers... choose well.
(I LOVE this kids' super hero choice... do you?)
Today we continue to THIEV our way through our textbook chapter "What is Life?"... by the end of class you should have your Headings and Evidence for all sections (maybe even all Vocabulary and Visuals as well)... Need more explanation for how Redi and Pasteur disproved Spontaneous Generation? Watch any of these videos...
Next week is a short week because of MEA days (teachers go to school Thursday and Friday!). We will observe our seeds AND continue with our THIEVES work and complete the End of section Q's and Summarize what we have learned. Worry about checking out a book next week if you aren't done with your THIEVES.
Very few of you have detail work tonight on the introduction or cleaning up your procedure... enjoy the break!
Time to apply the method. The question is "Which abiotic factor is most important for seeds to germinate?" Your task tonight is to write your hypothesis and procedure to test this hypothesis.
Tomorrow you will trade procedures with your partner and give feedback on the details for their steps. Be as detailed as you can because I just might have you trade procedures on Wednesday's planting day!
Make sure to give the "because" in your hypothesis AND be sure to list materials you may need for this experiment. IF you want to work on the introduction paragraph you may BUT it is also okay to wait for our class tomorrow to take another LAPS around the background information.

Be sure to complete any of the missing work you still owe or tomorrow afternoon is detention time for you!
So it seems that we can't state a theory of water drop behavior... more research needs to be done... The surface seems to play a part in our answer so KEEP TESTING! (not really... we are done with the lab... but I will keep testing year after year after year anyway). PS overall today we had 34% only rolling, 50% evenly split, and the remaining 16% still held on to sliding only.
Have a great weekend... some of you need to get all this past week's work finished so you can avoid the dreaded after school detention time on Tuesday... others have NO WORK TO DO and will get to chill and relax (or chillax even!).
Next week we design our own lab!
Well... does a water drop roll or does a water drop slide down a surface? Today you gathered YOUR data and tomorrow we will share our class data. We are trying to formulate a scientific theory of water drop behavior!
Sometimes in science we change our thinking about the how or why something happens... like when we once thought the earth was flat but now we know it to be round (actually a tad more bulging in the center... like so many of us older folks!)...
People used to think that life could just "pop" and appear (they called it spontaneous generation) but Francisco Redi changed their minds with a simple experiment to prove that living things come from other living things and NOT from spontaneous generation (we will discuss more with Mr. Redi in a few weeks).
Remember to finish the analysis and conclusion questions on your lab #1-5 (can't answer 6 YET)... Hopefully this post can help you with answering #4 if you are having some troubles... Here's the song from today too.
KMS Science Teacher
Most science pictures I post are found from assorted Facebook science pages... too numerous to cite specifically and downloaded for "just the right time"... I am sorry for the poor citation example I am setting.
In addition the archives are primarily from my days as a ONLY a life science teacher ... 2020 has changed all that!
