Monday: A Day
Aim: How
do animals reproduce asexually?
Do Now: Examine some of the organisms
in class. Hydra, amoeba, paramecium, planarian, starfish. How would these organisms reproduce? DO they have reproductive parts?
Procedure: Sometimes only one parent is necessary
for reproduction. Have students provide information they already know about asexual reproduction in a KWL chart. (1. Egg and
sperm not used. 2. Sexual organs are not present 3. There is no meiosis. 4. Mitosis is involved. 5. Offspring are identical
to one another. CLONES) Discuss types of asexual reproduction: Budding: Hydra, Regeneration: Starfish and planarian, Sporulation:
Mushroom or bread mold, Binary fission: amoeba, paramiecium and bacteria
Homework #3: UPCO BOOK page 329 Part
A, B, and C all questions.
Tuesday: B Day Afternoon IEP Training
Aim: To enhance their science glossaries
Do Now: Draw a picture that shows how a hydra reproduces asexually.
Procedure: Students will use the terms in their UPCO books on page 335. They will define
each term in their science glossaries.
Homework: Free Homework night for all.
Wednesday: A
Day
Aim:
What are the reproductive cells of bread mold?
Do Now: Students will draw a diagram of bread mold and label the reproductive cells. Get lab folder and
record Lab #8. Bread mold: Asexual reproduction: Use Lab investigation sheet from page 333 in UPCO book.
Procedure: Students will create slides of bread mold to view the reproductive cells. They will also use
a hand lens and a stereoscopic microscope to view the mold. Students will be responsible for the lab on page 333-334 in their
UPCO Books. Sexual and Asexual idea maps on pages 504 and 507 should be copied into notebooks.
Homework #4: UPCO Book:
Complete Part D, E and F on pages 331-331. ALl questions
Thursday: B Day
Aim: How do animals reproduce sexually?
Do Now: Make a list of everything you
already know about sexual reproduction.
Procedure: Sometimes two parents are necessary
for reproduction. Have students provide information they already know about sexual reproduction in a KWL chart. (1. Egg and
sperm are used. 2. Sexual organs are present 3. There is meiosis. 4. Mating is involved. 5. Offspring are different
from the parents and can have better traits than the parent. DEFINE FERTILIZATION: Egg ans Sperm join outside the body.
Students will see how fertilization occurs two ways. External
fertilization occurs outside the body. Most animals with E.F. live in or near water. Discuss the need. How can these animals
ensure that the egg and sperm meets? Thousands of sex cells, gather in large groups, Fish starfish, sponges and frogs.
INTERNAL FERTILIZATION: joining of egg and sperm inside the female organism. Reproduce on land, usually protect their young
and care for their young. Allows for reproduction out of water. Example: humans, mammals. Show external fertilization on the
laser disc player. Complete the enrichment activity
Homework #5: Complete the critical thinking worksheet:
Bearing more than one animal at a time.
Friday: A Day
Aim: What is a breeding season and an estrous cycle?
Do Now: Complete the idea map for sexual reproduction
Procedure: Students will define a breeding season: Time of year when animals reproduce. Many animals breed
in the Spring or when weather conditions are optimal. Deer breed in the fall. What is an estrous cycle? A cycle in which the
female will only mate at certain times. Ex: dogs: two per year, rats every five days a cow has a 20 day cycle. Female humans
have a 28 day cycle. A gestation period is the time a female carries the young for. How long they are pregnant. Complete
the check your understanding questions on page 506 and 510 questions 1-10. Complete the bar graphs comparing estrous
HAVE A GREAT WEEKEND!
See You Monday!
