   2. If you did not get to do a bug box and you want to, please let me know.

Due October 20

No regular homework, because several students will be completing their entomology boxes on Monday,  If you are interested, please call Mrs. M. and show your parent the letter below.

Dear Parents of 7-8 science students,

          Several students in our class have collected and frozen insects to build entomology collection boxes.  Other students were not able to find very many, because our first freeze came early.  Therefore, those who would like to create an entomology display box with their insects will meet in the science room next Monday (October 19) at 12:00 to classify and mount our bugs.  If your student is here in the morning, they may bring a lunch and stay. We will need about an hour and a half to complete the boxes.  They will need to tell me if they are staying and will have to bring their collected insects.

          Because of the insect project, the only homework this week will be to use their notes and pictures from our dissection to compare a grasshopper to a human.  They may use a Venn diagram, a chart, or paragraph descriptions.

Thank you for the privilege of teaching your children,

Susie Marshall

Science Teacher

Due October 13

7 – 8 science

1.       Research the grasshopper in an encyclopedia or on the internet to prepare for our dissection next week. Find out:

a.       How they eat

b.      What they eat

c.       Who eats them

d.      If they fly and how

e.       What 3 or 4 of the organs below do divide the list with your partner

2.      On the diagram below label:

a.       The antenna

b.      The compound eye

c.       The fore & hind wings

d.      The abdomen

e.       The femur

f.       The sternum

g.       The hearts

h.       The crop

i.         The digestive tract

 Looks like this grasshopper did not copy....please find another...

3. Find an ant or termite nest and watch it

Due October 6:

7 – 8 Science

1. Read Chapter 2-2 on Arthropods.
2. Find an arthropod in your yard and watch it closely for 10 – 15 minutes.  Then write a 6-8 sentence paragraph about your arthropod’s life, without saying its type. Be sure to include movement, what it eats, relationships to others, etc. We will read these in class next week and try to guess who they are.
3. If possible bring an arthropod to dissect in you bug killing jar.
4. Continue to collect and freeze bugs.

Due September 22

1. Continue to collect, kill and freeze insects until you have 15 – 20 samples of different insects in a labeled jar or box in your freezer.
2. Bring one dead bug to class, that you think has all of its parts still attached
3. Read “Animals” pages 55 – 59. Design an insect that has all of the correct characteristics.  Explain what it eats, how it eats, and its life cycle.  You may do this with a physical model (food, legos, etc.) or by drawing it on paper.
4. Give this letter to your parents.

September 15, 2009

Dear parents,

     The students in the grades 7-8 science class have voted to start the year with a study of insects.  This study will include the creation of entomology boxes which showcase the bugs they have collected. We will make the boxes in November, but the insects need to be collected in September, before they all die. Today we practiced collecting bugs; however most of the bugs will need to be caught, killed and frozen at home.

     To do this they will need to prepare materials, collect insects and freeze them carefully.  This may take several sessions in the backyard or nearby bush.  The materials include a quart jar with lid, paper towels, some finger-nail polish remover, and some space in a freezer.  The paper towels are wadded up and put at the bottom of the jar. Then about 2 teaspoons of polish remover are poured over the paper towels. The acetone in the polish remover will kill the bugs painlessly and quickly. Then they need to freeze the bugs gently to maintain their structure. One small flat box that is well labeled in the freezer will hold them for several months.

Thank you for supporting our process,

Mrs. Marshall

                                                                             September 15

Dear parents,

     Today your science student brought home a middle school level science book entitled “From Bacteria to Plants.” The information and visuals are well done, however the vocabulary is challenging.  Please read the assigned nine pages (6 – 14) with your student, helping them with words and concepts where needed. Then, please, make some notes below about what you thought of the book for your student, and have them return it to school with their homework (on the back side).

1. For my student, this book is:
   1. A good resource for science
   2. A book I would like to read with them
   3. Appropriate with in school help on vocabulary and reading strategies
   4. Too difficult
   5. Other: __________________________________________

2. I use a science book at home and would rather they not have one from school. T   F 

3. One hour per week to read and prepare for science class is doable for my child.   T   F

Due September 15

    1. Bring something to class that is living and very small = less than 2 inches. Bring it in a sealed container.  Be sure that you know what it is.

7-8 Graders: Bring in a mason jar

4-6 Graders: Bring a fungus that is not a mushroom in a sealed container.
