Ever wonder why humans spend 1/3 of our lives sleeping? Watch the PBS NOVA episode Mysteries of Sleep and learn the answer to that question and more!
Learn more about the connection between adenosine, caffeine, and sleep by watching the TedEd video below:

- Create a sleep journal. Think about the factors that might impact your sleep each day, then track those along with how much sleep you get each night. Which factors seem to affect your sleep? Which factors don’t seem affect your sleep? Add and remove factors to help you dial in on how to get the best possible sleep each night.
- Create a dream diary. Record your dreams upon waking. Write them down, draw them out, or narrate them into your phone. Notice any trends or patterns? How often are you able to recall your dreams? Does your ability to remember your dreams correlate with how long or how well you sleep? Does the content of your dreams correlate with your past, present, or future experiences? Do you have recurring dreams?
- Learning to remember. Feeling tired after a long day of learning at school? Try a Power Nap and see whether it helps you remember what you learned during the day. Are you more efficient at completing homework before or after a Power Nap?
Welcome to the Evidence for Change across Time activity! As part of our Evolution Project, you were tasked with identifying careers associated with the study of evolution. We will expand on what you learned about those careers in this activity. You will be assigned to one of four careers. Your job: complete the assigned tasks for your career. Some parts of the activity should be completed as a team. Other parts are to be completed individually, with the understanding that the members of your group are available for consultation. You are expected to actively engage in your own learning and to share your learning with others.
For this project, you will be assigned to a team of 3 or 4 students. Each team will receive a folder. Please keep the materials in the folder organized as they will be used by students in multiple classes. You are expected to sit with your team this week and use class time efficiently. Please do not ask to change groups. You will present your work Friday, so your research and presentations must be completed and assembled before class begins Friday.
This work will count as your Evolution Unit Final Exam. To receive credit, you must complete all individual and group work, document all of your research, and turn in all of your documentation in addition to preparing and sharing your findings during the presentation. This will be your final grade for third quarter. Late work will not be accepted.
Once you receive your assignment, it’s time to go to work!
Last week, we learned about Darwin’s voyage and how he collected data to formulate his theory of evolution. We went on to study biological classification, using the system devised by Linneaus way back in 1735. Previously, we learned that scientists collecting were able to date common ancestors of humans to over 3 million years ago. Our work over the next few days will be to learn how scientists use radiometric dating to estimate the age of really old samples. We will begin an introduction to chemistry, focusing our efforts on understanding the difference between carbon-12 and carbon-14 atoms. Class notes are pictured below:
Next, we will watch a video introducing radiocarbon dating:
After the video, we will begin the Radioisotopes Activity. We will read through the first few pages, and then tomorrow students will work with a partner to complete the activity which is anticipated to wrap up by Wednesday.
