2. Remember to write complete sentences when doing your bell work.
Bell work 26 February 22, 2016
* You will need your composition books today.*
Take out a sheet of paper, write your name, class period, and date in the top right hand corner. Write Bell Work 26 on the top margin, skip a line, write Monday, and answer the following questions.
What is an organism?
What was the difference between the male and female milkweed bugs?
What do you think a population is?
Remember to write complete sentences when doing your bell work.

3. Determine male and female milkweed bugs
Focus on the markings on the ventral (belly) side of the bugs.
Teacher master A, Male and Female Milkweed Bugs
Swap petri dishes and see if you notice a difference
You should notice a difference in the black marks on the third abdominal segment.
Each table should have both sexes.

4. 12. Record gender differences
Draw pictures of the ventral sides of the milkweed bugs on your lab sheet

5. 12. Record gender differences
The third segment from the tip of the male’s abdomen is solid black on the ventral (belly) side.
The same segment on the female has two large spots with orange in the middle.
Also, the female is usually a little larger than the male.

6. 13. Reproduction How do milkweed bugs reproduce their own kind?
We know that nothing lives forever.
For milkweed bugs to continue on Earth, new ones must come into being all the time.
One question we should seek to answer is
How do milkweed bugs reproduce their own kind?
During the next class you will make a supportive habitat and place on e male and one female in it.

7. 15. Vocabulary 1.1 write the definitions and put the page in your index
Habitat: a place where an organism lives that supports its requirements for life
Observation: noticing the properties of an object or event with one or more of the five senses (sight, hearing, touch, smell, and taste)
Organism: a living thing
Population: all the individuals of one kind (one species) in a specified area at one time
Species: a kind of organism. Members of a species are all the same kind of organism and are different from all other kinds of organisms.

8. Put this in your notebook and in your table of contents
Focus Question 1.2
Put this in your notebook and in your table of contents
What needs to be considered when building a habitat for milkweed bugs?
Write down your thoughts. We will revisit

9. 2 Habitat project
We are going to raise milkweed bugs in order to learn more about their reproductive cycle.
For that we will need to make a suitable habitat and put a male and female into the habitat.

10. 3. Habitat tasks B: Habitat for Milkweed Bugs C D
Get your Materials for your task
Everyone in your group needs to participate

11. 7. Earthworm habitat
I have another population I want you to look at.
What are these? Earthworms
What are they used for?
Fishing bait, composting.
Where do they usually live? In the ground

12. 7. Earthworm habitat
We aren’t going to make detailed observations of them today but we will in a few weeks.
Until then, I have assembled a worm habitat in a jar.
It has all the things the worms will need: food, water, and shelter.
The jar goes in a black plastic bag so it’s dark.
We’ll add food and moisture occasionally so the worms will survive until we need them.

13. 8. Reading in Science Resources
Look and discuss:
the cover of FOSS Science Resources: Populations and Ecosystems.
Also the table of contents.
Locate the glossary and index.’
Complete the wrap-up activities

14. 9. Milkweed bugs
We need to add one male and one female milkweed bugs to their new habitat
Make sure that you have one male and one female at each table.
Swap with another table if needed.

15. Reading Observations and inferences Column 1
Take a moment and share your observations with your table
Review your list of observations for the photo.
Label (or add) one qualitative observation and one quantitative observation.
Share with the class.

16. Reading Observations and inferences column 2
Under the list of observations, record and label one inference you could make based on the photo.
Share your examples

17. Reading Observations and inferences
Complete the T-chart in your notebooks
Be ready to share which are observations and which are inferences.
Lastly, update your responses.
