why bat is a mammal and penguin is an Aves?

if you observing the video above you can see the body of a bat is covered with fur not with feather and the bats give birth while Aves should lay eggs.

A penguin on the other hand, looks like it covered with fur, but if you take a closer look.....the penguin's body is covered by small and stiff feathers, and they also lay eggs (click it if you want to see the movie).

picture taken from:

http://www.seaworld.org/animal-info/info-books/penguin/images/pic-incubating-single-egg.jpg

visit this web to observe their feathers:

answer for your questions (2) update

Hi…..

these are the answer for the questions from the other classes and 1 which is left behind to answer because it is a simple question but it need time to think about it. A good one, and apparently some of you have similar question.

Can you tell me how to study in a good way?

What if we don’t understand the lesson that had been taught over and over again?

How to understand the lesson which is delivered in English?

For all the questions above……

Do you remember ‘the super brain’ tips? Well it could help you.

For me, there are some steps:

1. Stop saying I can’t, and starts saying I can

2. understand myself( ie: am I auditory/visual/kinesthetic type of student?, will I remember better if my note is in the form of mind map/ small cards/colorful notes/something else?, how can I encourage myself to study harder?, how to overcome my weaknesses?, etc)

3. set a goal

4. always searching for the answer if I don’t understand, not only from my mentor/supervisor, sometimes I search from the internet, another time I ask my capable experienced friends (sometimes they are older than me, sometimes they are younger. There was a time when I learn how to use the computer and organize his blog from a student). The key is never hesitate and never fell inferior/ashamed just because you fell you don’t understand. Never stop learning!

5. Never afraid to make mistakes. Take it as a part of learning. Takes failure as a postponed success, learn from it and move forward. Trying a new method sometimes makes me afraid to fail, but I always try to overcome it by saying to myself “I’d better try and fail than never” I won’t learn anything if I never try:).

6. Reflection. Sometimes after I did a thing, I tries to think what I did best, what I need to increase to get better, what are the obstacles, how to overcome it if I have to face it again, something like that…usually at night

7. Last but not least…I learn for myself, for my future, as a step to reach my dream….that way I learn with a happy felling. Believe me it’s a way…..different effect if you learn to make other people satisfied because they keep telling you it’s something you have to do. So find your own motivation, it’s the key!

Inform me if it could help you, and if other reader have opinion which could help your friend here, sharing it will be helpful

When is your birthday?

March 13

How do you make your assessment?

Your question is not clear enough. Is it for final mark in your report card? I think you had your explanation during your ‘Mabis’

Why the class is separated into biology class and physics class?

Try to answer this question:

Which class would help you learn better?

· Class A which have 5 students in a classroom with 1 teacher

· Class B which have 100 students in a classroom with 1 teacher

Your class is not separated to learn two different things, because on the third and fourth period Biology class will learn about physics and physics class will learn about biology.

Will we have a lots of experiments?

You will have enough experiments which depends on the topic.

How old are you?

Still young, why you want to know?

See you next time…..

My first impression for Grade 7….you didn’t ask too much, which could be a good thing in one way and not too good in the other way. I hope it was because you understand all of my explanation and agree to all of it…..other way it means you were afraid to ask.
Well don’t be afraid, you are a student and you have to ask to get knowledge! Although when you are asking something to anybody, please remember…….’care & respect’.

Now… the answer:
How long have you been in Santa Laurensia?
I’ve been here since August 1st 2007, so how long have I been working here?
What is your hobby?
Reading, eating, drawing, traveling
Miss, can we use a note book with colorful pages?
What is the purpose of a note book?
Will a colorful note book help you to understand better?
This book is not for me, so please decide after you know the answer of the questions above.
Where are you from?
Surakarta is my hometown
Where do you live?
At the teacher’s dormitory near the school. Couldn’t mention the address….I have enough seeing you during school, no offense…ok?:)

oh...one thing, the Classroom procedures will be here after I met 7 C, D, E and F

here are some of the information that you have to remember:

Supplies to bring to class:

A. self and Brain

B. Materials (1. SIF 2. Exercise book 3. Note book 4. Clear Holder)

C. Home Work ( 1.Assignment 2.Internet 3.newspaper )

Biology class rules:

#Always write your full name/number and class correctly
#Collect your assignment and homework on time & well done
#Never forget to raise your hand and wait for the permission before you speak.
#Permission to the toilet will be given only 5 minutes at the beginning of the class.

#Always answering all my questions during the test, quiz, assignment, presentation, etc in English! If you can’t mix it with Indonesian/Bahasa! If you answering all in Indonesian, I will consider the answer do not exist
#No correction pen during the test and quiz.

#Bringing dictionary during the test and class period is your own responsibility, borrowing during the test is not allowed.
#Bring your clear holder with all its contents, note book, and exercise book
#Bring your SIF Biology when our topics are: characteristics of living things, the five kingdoms, cell, and ecosystem.

#For every violation, I will give you a personal assignment. If you are late collecting it, that means you want your assignment to be doubly.

Have a nice day.......

Invertebrates-hndout

1.Phylum Porifera
Every one of you might be familiar with Sponge Bob right? Well the author refers to this asymmetrical phylum of vertebrates known as the sponge.
It is called the simplest form of animal life because although they are multicellular organisms which contain several different cell types
they are lacking true tissue.
They are aquatic animals (live in water) and do not move around (sessile animal) with lots of pores (holes) all over their bodies. They are all filter feeders (animals that obtain nutrients by filtering suspended particles or small organisms from water). Most sponges have spikes which support it, keeping it upright in the water and defending itself from the predators.

Examples: tube sponge, glass sponge, sea sponge

picture of tube sponge:

2.Phylum Cnidaria
Members of this phylum have radial symmetry, they are aquatic animals. Most of them have tentacles arranged in a ring around their mouth with nematocysts (stinging cells which can release toxic or sticky substances to paralyze the prey). It has a gastrovascular cavity for digestion with one single opening to this cavity that functions as both mouth and anus. They have two different body plans:
1).Polyp (sessile, reproduce by budding)
2).Medusa (motile, sexual reproduction)
hydraSome species of cnidarians live in a colony (a group of many individual animals living together), one of them is stony coral. Both sea anemones and coral occurs only as polyps in the marine world. Other species such as hydra prefer to live soliter (alone) in a fresh water habitat.
Examples : jellyfish, hydra, sea anemones, coral

hydra: sea anemone:
picture of stony coral :
3. Phylum Molusca
They are invertebrates with soft bodies that are often protected by a hard outer shell. A mollusk has a thin layer of tissue called a mantle that covers its internal organs, which in many mollusks produce a hard shell. It has a digestive system with two opening. Three major classes of mollusca are
· Class Gastropoda (some have shells and move with a muscular foot; ex: snail & sea slug)

· Class Bivalvia (have two shells held together; filter feeder; ex: oyster, clams, scallop)

· Class Cephalopoda (have tentacles→ modification from muscular foot; no shell except nautiluses; ex: octopuses & squid)

Vermes: worm like
The simplest animal with a brain which are sensitive to light, touch, and vibration from the environment. For example, if an earth worm on the surface of the ground gets too much light or senses vibration of a foot step, the worm will quickly return underground to avoid it.
4.Phylum
Platyhelminthes
They are known as flatworms because they are flat like a ribbon and as soft as jelly. They have bilateral symmetry. Many flatworm are parasites in vertebrates bodies (ex: tape worm and flukes), while some of them (ex: planarian) are free living in the aquatic or damp soil habitat.
planarian:

tapeworm:
5.Phylum
Nematoda
Known as a round worm it has a cylindrical body. They look like tiny strands of cooked spaghetti, which are pointed at each end. It has a digestive system that is like a tube, open at both ends (starts from mouth and ends in anus).
Some of them are parasites (ie: Ascaris lumbricoides and hook worms) or free living animals.
6.Phylum Annelida
Known as segmented worms which have bodies made of many linked sections known as segments. Earth worms and leeches are included in this phylum. They are hermaphrodites (have male and female reproductive organs in one organism) but they cross-fertilize. Earth worms respirate through their moist skin.

7. Phylum Arthropoda
Athopod means jointed legs. All arthropods have an exoskeleton or outer skeleton (have skeleton outside the body) which protects them and helps prevent water evaporation. They have a segmented body and jointed attachment called appendages (wings, mouth parts, and legs). They have bilateral symmetry, and open circulatory system with two openings.
Metamorphosis: The body form changes from embryo to adults. It increase in size, reorganizes tissue, remodels its body parts.
Complete: egg→larva→pupa→adult

Incomplete: egg→nymph→adult

insecta:
compound eye:arachnid:
crustaceae:
myriapoda:8. Phylum Echinodermata

They are invertebrates with an endoskeleton and water vascular system (a network of internal canals to pump water to the different parts of their body for movement, feeding and gas exchange). The skin of most echinoderms is covered by spines. They have bilateral symmetry as larvae and pentaradial symmetry as adults (body part usually in multiples of five). Adults have no head or brain and they live in salt water. They have tube feet for movement, the end of them are sticky. When filled with water they act like small sticky suction cups. The stickiness and suction enable the tube feet to grip the surface beneath the echinoderm so it can move along slowly and can help it to capture food. Respiration of echinoderm is done using skin gills.
