For Thursday.....                 More than just Bait -   OMM online text lesson 3     Interactive notes!                                                                       California Black Worm    Lumbriculus variegatus         Segmented worms that are small but complex!


Positions on the body:    Anterior  -- head region (rounded)          Posterior – tail region  (pointed)

                                                 Dorsal - back or top surface         Ventral - front/bell region


1.  Movement – describe how they move through water and soil. 


2.  Respiration (gas exchange)... how does oxygen get into the Lumbriculus?


Reflex actions:  rapid jerky motions forward or backward for defense.  Photoreceptors in tail region detect shadows and the worm reacts.


3.  Digestive System --- what does it look like?


  1. Circulatory System --- what does it look like?


They have no heart so how does the blood get pushed through the body?


Reproduction –  Blackworms can reproduce both sexually or asexually

  • Asexual reproduction is most commonly seen  - fragmentation and regeneration     Produces offspring identical to the parent
  • Sexual reproduction – possible but more rarely seen   unique offspring


5.  What is a related organism?


6.  What is the clitellum?


7.  What are castings?


8.  How are these worms helpful in the environment?





9.  Name at least three organisms that can regenerate?

WAS #2 Nature of Science 1/12/15   


This Week in Science   1/12/15   Nature of Science

  (Quizlet:  Nature of Science - Adams

Monday:  More on Controlled Experiments.  Homework:  Quiz tomorrow over the concepts we have covered and completed vocabulary.  Work on your study guide for test on Thursday.  

Tuesday:  Quiz!  Theories and Laws of science.     Homework:  Notebook check is coming-make sure all your materials are complete and up to date.  Complete the study guide and prepare for test.               

 Wednesday:   Study guide will be checked and discussed.   Homework:    Study for test!

Thursday:    Test on Nature of Science      Homework:  Make sure your notebook is up to date for notebook check tomorrow.

Friday:  Notebook Check.  Planting of Fast Plants and radishes.    Homework:  none



 How would you design an experiment...You notice that the flowers of a particular plant are pink one year and then the flowers bloom blue the following year. Your friend tells you that adding Miracle-Gro fertilizer to the soil causes the pink flowers to be blue the following yearYou decide to set up a controlled experiment to test this idea.


What is your hypothesis?  


Show how your experiment will be carried out.  What is your independent variable?   

What is your dependent variable?                              Label your control and experimental setups.




          What are some of the constants?

      pastedGraphic.pdf                                                                                                 pastedGraphic_1.pdf





How you will know if your hypothesis is supported? 


How long your experiment will run?      



Controlled Experiments!  

7th graders in Minnesota found many deformed frogs in the creek by their school!


Question:  Why are many deformed frogs being found?


Hypothesis:  Higher levels of UV light may be causing the deformities.  If higher levels of UV light are causing the deformities then higher numbers of frogs will show deformities when living under UV as compared to normal lighting because of the possibility of DNA damage from UV exposure.


Materials:  3 tanks,  2 UV lights,   1 regular light,   frog eggs


What are some constants that must be maintained in each group?


How many frog eggs (trials) should we test?



pastedGraphic_2.pdf                   pastedGraphic_3.pdf                    pastedGraphic_4.pdf



Control                 Experimental group 1     Experimental group 2



What is the independent variable?

What is the dependent variable?

How will we know if the hypothesis is supported?



If the hypothesis is supported, is this absolute proof that our hypothesis is true?




Why is it important to have more than 1 or 2 trials of the experiment (in this case frogs)?

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?




Further Questions:








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?
