(Quizlet: Nature of Science - Adams http://quizlet.com/18098841/nature-of-science-adams-flash-cards/)
Tuesday: Welcome! Introductions, syllabus and procedures. Lab safety and equipment will be introduced. What is a life scientist? Assignment: Return your forms and complete the Explorer Activity with write up. Have parents email me for a surprize!
Wednesday: Scientific skill building. More on lab safety (http://www.youtube.com/watch?v=xJG0ir9nDtc&sns=em Discuss homework results. Notes and discussion on scientific methods and the global nature of science. Observation and collection of data. Assignment: Complete your observation sheet as needed. Looking at your bedroom... write 3 quantitative and 3 qualitative observations about it in your foldable.
Thursday: Science notebooks. Scientific method and controlled experiments. Assignment: Study vocabulary-visit quizlet! Make sure your notebook is up to date with all materials in place... be ready to share your author page on Monday.
Friday: More on variables and controlled experiments. Assignment: Study vocabulary/concepts. Complete your author’s page. Look at the example of the controlled experiment (color of fall leaves) on the back of the weekly assignment sheet and answer the questions.
Vocabulary: Biology Scientific methods Hypothesis Controlled experiment Constants Control Trials Dependent variable Independent variable Experimental group Peer review Bias Theory Scientific law

Explorer activity for Tuesday night
Question: How accurate are our senses?
Hypothesis: (An educated guess-the possible answer to your question) If we place our hands into different temperatures of water, then we will be able to accurately predict the water temperature because of our past experiences.
Materials: 3 large bowls or pans, very warm water, very cold water, room temperature water.
Set up- Place 3 large bowls on a table. Add very warm water to the left hand bowl. Add ice water (very cold water) to the right hand bowl. In the center bowl, add room temperature water. Immediately place your left hand in the warm water and your right hand in the ice water. Keep hands under the water for 1 minute. Next, place both hands in the center bowl at the same time.
Results/data: Sketch the experimental setup below/record what you observed - Did both hands feel the same?
Conclusions: Was the hypothesis supported by your experiment? Why or why not?
For later this week! Colors of the Leaves….You see the colors of the leaves changing in the fall and wonder why this happens. You think it is because the trees experience cooler temperatures in the fall. You want to set up a controlled experiment to test this idea. Your greenhouse is divided into 2 sections where the temperature can be regulated. One side stays at 80 degrees while the other side is kept at a constant 55 degrees. You have 20 maple trees in similar pots placed in each area of the greenhouse.
A. What is your question?
B. What is your hypothesis?
C. What is your control setup going to be?
D. What is your independent variable going to be?
E. Constants in both areas:
F. What kind of data will you record (dependent variable)?
G. How long will your experiment run?
H. How will you decide if your hypothesis is supported?
