Today we learned a bit about Charles Darwin and his scientific discoveries. We had a productive work day finding definitions for the terms related to Darwin's work: species, fossils, adaptations, evolution, natural selection, and variation. Remember we define species and fossils on page 130, adaptations and evolution on page 131, and natural selection and variation on p. 132 using the three column note strategy used in Kelner's classes (only THIS time add illustrations!). We will continue to support the analysis part of your definitions Monday (IF YOU MISSED CLASS TODAY YOU CAN CATCH UP MONDAY). If you need or want to explore more about variation and natural selection you may want to explore THIS AMAZING WEBSITE. Your "Nature at Work" labs were collected today... make sure you answer #1-3 (save #4 for later!)...
AND TODAY IS ARBOR DAY! YAY TO TREES FOR PHOTOSYNTHESIZING AND GIVING YOU O2!

Today we analyzed the death rate of our mice in the white sand environment (it's not easy to be a brown mouse in a white habitat!) and then discovered how a dark forest floor would affect the white mouse population. THIS SITE EXPLAINS JUST HOW AND WHY NATURAL SELECTION OCCURS with these mice. Pretty cool to see the results in nature match our lab results! Be sure to finish all analysis AND questions 1, 2, and 3 only (skip 4 and anything on the back side for now). Tomorrow we will work on vocabulary! We reviewed how variations in traits occur (mutation!) and then we started a lab exploring how variation affects natural selection! IF YOU MISSED CLASS TODAY you should WATCH THIS and get the data upon return. Tomorrow we will analyze how the brown mouse fared in the white sand environment and then predict how they'll do in a dark forest floor. We will clearly observe how variation affects speciation!  Today is DNA day! On this date in 1953, Watson and Crick published their paper in the journal Nature describing the structure of DNA. The day celebrates the discovery and understanding of DNA and the scientific advances that understanding has made possible. Thanks fellas (and Roslyn!)!!!  Today we explored the diversity of life BECAUSE of DNA mistakes! Tomorrow we shall explore how variation in traits will change the selection of individuals in their habitat! IF YOU MISSED TODAY: Watch this!  Today we spent the morning in SBAC testing and then the afternoon classes had another exploration day for Learn Genetics. Tomorrow we will revisit mutations and discover how these SNPs give us diversity of life!   I don't know the answer ... but I know I am ONE who is trying ... join me ???
Today we wrapped up our genetics unit with a SWYK... IF YOU MISSED CLASS TODAY you will need to make up this task upon your return. THIS WEEKEND IS EARTH DAY (celebrate in Whitefish on Saturday) and THE MARCH FOR SCIENCE (register to join virtually OR join one of the satellite marches in Montana). Get out and enjoy nature, pick up garbage in your neighborhood, or join us at KMS to work in the gardens for GLOBAL YOUTH SERVICE DAY. We need to take care of our planet so it can take care of us... get involved, be informed, speak up, be active, insist on good science, and sustainability! It's time to get off the sidelines and make a difference  Today we explored just a bit more with advancements in genetics: gene therapies, research with identical twin genomes, and more with genetic engineering. Tomorrow we SWYK on these advancements. You will need to write a paragraph with at least TWO advancements explained AND supported as to why this is so cool. Be ready for a great final CEAEAEAL for the genetics unit... next up: Natural Selection (DNA still is involved!!!).   Today period 1 had regular science class (did exactly the same exploration of LEARN GENETICS) and the others were SBAC testing (or waiting to). Tomorrow we will continue exploration of genetic advancements!
Today was a day of exploration on the LEARN GENETICS SCIENCE LEARNING CENTER SITE investigating many COOL advancements involving our DNA and genetics. Wow... such a bright future! We made a list of at least 3 advancements as well as WHY they are so cool and important (notebook p. 126)! Your textbook pages 123-128/130-131 also discusses advances in genetics. We will have our final genetics SWYK on Thursday. IF YOU MISSED CLASS TODAY you need to visit the LEARN GENETICS SITE and explore. SBAC testing begins tomorrow periods 3-5 ... sleep well tonight and have a good breakfast!!!  Today April the giraffe FINALLY had her baby! Click THIS LINK AND FWD TO WATCH THE BIRTH (it's gonna be a birth... complete with gushing placental sac and fluids. You can also fwd to watch the baby get on its feet and try walking). I love watching the patterns of her belly during the contractions... you can see how the muscles move. Pretty amazing what a body can do! Did you know that recently we have changed our classification of giraffes species based on DNA and genetics? YEP! READ ABOUT IT HERE!  |
