In her book Mapping the Mind, Rita Carter (1998) states that the teaching
and learning process is all about relationships. In fact, unless this emotional
engagement is made, learning will not “stick” positively in the memory
(Goleman, 1996; Jensen, 2005; LeDoux, 1996).
In order to form a relationship, clear ground rules need to be established
(Prentice, 2007). Because the teacher is the adult, this is the teacher’s responsibility.

How Animations are Made
How Animations are Made
You don't need to make your own animations. There are a lot of them in the internet. Almost every topic in high school.
You need to learn how to use them. Complete the following steps:
1. Own a computer or laptop, if that is still a plan, own a USB flash drive
2. Download Adobe Flash Player 9 here.
3. Install Adobe Flash Player. Just double click on what you have downloaded and answer next or yes to every prompt that pops up. It's safe of course, I will bet my christmas bonus.
4. Search for animations of your lessons. It is not that easy to find these animations but there are so many of them. I have put up a list of several animations in the next section and a tool for searching. Go get it.
Water Cycle Animation
Water Cycle Animation
Cool huh? Use this in your classroom, let your students click through the options presented in this animation and they will surely have a lot of fun. They will have a lot of learning.
I remember teaching a second year high school class using the animation above. This section is a notorious section, 53% of the teachers hated them for their behavior. That's 8 out of 15, the 7 techers don't have a class with them.
I let them choose the options in the animation. I discussed, they listened. I asked who wants to try the other questions in the animation and they all raise their hands. They smiled. They focused on the lesson. No quarel, no noise, no talking other things. It was the best day I had with them.
It's not powerpoint. It's flash. The animation above was not made with Powerpoint and it is not a video. Videos are not very interactive. But flash is interactive.
Flash is the same technology used in Facebook games. You've played Farmville, haven't you? Then it's the same as the animation above. Tetris Battle is also flash.
Now I will guide you in using this technology. This next step is the start of something new.

Globe Tatoo vs Smart Bro vs Sun Broadband
Wireless broadband in the Philippines is now highly praised and highly priced. The convenience that these broadband sticks provide makes them very ideal for people who travel a lot with their laptops and netbooks or even with desktop computer users in the Philippines.However, many Filipinos are also complaining about the high price that the three companies offering these sticks stamp on them.
A broadband stick usually costs between 1000 pesos to 1400 pesos. Using it will cost you 20 pesos per hour. If you subscribe to their unlimited service, you will be paying 50 pesos per day.
Because of this, we have to compare these three brands and choose what's the best.
Getting to Know Each Other Classroom Activities
Emotional Links
Teaching and learning process is all about relationships. In fact, unless this emotional engagement is made, learning will not "stick" positively in the memory.
In order to form a relationship, clear ground rules need to be established. Because the teacher is the adult, this is the teacher's responsibility. However, with the emphasis on coverage of content, it can happen that these social expectations are never clearly shared with students. Part of the development of these expectations is sharing appropriate information about yourself. You may share about your family, your interests, and your ambitions, but this is not enough.
This then provides a knowledge base as to the "life rules" that you live by and expect in the classroom setting. Sharing your own thoughts and dreams develops a model of trust, which in turn gives students the opportunity to do the same. Use these exercises to open the lines of communication between you and your students.

Filipino Biologists
Lourdes J. Cruz. Her researches have contributed to the understanding of the
biochemistry of toxic peptides from the venom of fish-hunting Conus marine snails. The
characterization of over fifty biologically active peptides from the snails’ venom had been
made possible, in part, by her studies. Also, her work led to the development of conotoxins
used as tools for examining the activity of the human brain. For instance, w-Conotoxin is
widely used for studying neural calcium channels and m-Conotoxins is used when muscular
activity must be controlled to examine events at the synapse.
Clare R. Baltazar is the author of Philippine Insects, the first authoritative text on Philippine insects. Her numerous works on insects, especially on the Philippine Hymenoptera, are significant in laying down the framework of insect control in the future. She also discovered one subgenus of Hymenoptera and one hundred eight new species of the Philippine parasitic wasp.
Magdalena C. Cantoria. Dr. Cantoria’s researches focused particularly on the morphology, physiology, and biochemistry of drug plants. She has also done basic study on the pharmacognosy (or the study of the therapeutic substances) of agar, raulfia, datura, mint, and piper species.
Filomena F. Campos is recognized for her work on cotton research in the Philippines. Her contribution led to the development of a package of technology on cotton production achieved in relatively short period of three years. She was also deeply involved in the research on sunflower, which is a potential source of edible oil and livestock feed.
Benjamin D. Cabrera. Most of Dr. Cabrera’s works are on medical parasitology and public health. Parasitology is concerned with parasitism and the parasites, like intestinal parasites, its causes and possible prevention.
Because of his work on epidemiology and life cycle of filarial parasites, preventive measures through the development of drugs, can now be implemented on humans especially against mosquito carriers. With the model he proposed, ascariasis or soiltransmitted helminthes can now be reduced.
Eduardo A. Quisumbing is widely known in botany, especially for his work on taxonomy, systematics and morphology. His researches on Philippine medicinal plants and orchids are pioneering. He is the author of Medicinal Plants of the Philippines, which is considered a forerunner on the subject in our country today. He has also written one hundred twenty-nine scientific articles.
Francisco M. Fronda. Dr. Fronda’s most significant contribution is the development of poultry industry in the Philippines as well as in the Asian region. His title as the “Father of Poultry Science in the Philippines” is but fitting to his share in the development of the poultry and livestock industry. He spent over six decades – virtually a lifetime – teaching, doing researches and extension work, and he truly deserves the honor.
Emerita V. de Guzman. The outstanding contribution of Dr. de Guzman is the development of the makapuno embryo inside a test tube (in vitro development). This discovery has dramatically changed the ratio of the makapuno-bearing nuts in the tropics which ranges only three to five makapuno nuts in every raceme or cluster of fourteen to nineteen nuts. Dr. de Guzman successfully produced one hundred per cent all makapunobearing nuts in a cluster.
Emil Q. Javier. Dr.Javier has been known for his practical and realistic approaches to the problems confronting the small farmers, especially in a tropical and developing country like the Philippines. Keenly aware of the limited resources of the small farmers, Dr. Javier directed his researches towards developing practical methods to improve crop production using cheap, indigenous materials.
Jovenito D. Soriano. Some of Dr. Soriano’s studies on plant cytogenetics (or the study dealing with the cells and their processes) and researches on mutations have been published in international journals. He shed light on the understanding of the mutation process (mutation is the process of cell transformation or cell change).

Microscope and Other Tools in Biology
The subject of this lesson is the MICROSCOPE. The microscope is a tool used to
study objects too small to be seen with the unaided eye. You will be using the microscope
to discover a whole world of life too small to be seen with the eye alone. The study of the
diversity of life will begin with microscopic organisms and progress to the largest organism.
The microscope enlarges the image of a small object. In your biology class, you will be using the compound microscope. It consists of two lenses, each fitted into the end of a tube within a tube.
How to Prepare the Microscope
The word microscope comes from the Greek word micro meaning “small” and scopein meaning “to see or view.” The purpose of a microscope is to magnify small objects so that they can be seen.
The microscope that you will be using is both a light and a compound microscope. The light for your microscope will come from sunlight. The word compound refers to a microscope with two lenses or a set of lenses. There are two sets of lenses in a microscope, one at each end of the body tube. The two sets of lenses are called the EYEPIECE and the OBJECTIVE.
How to Focus the Microscope
The purpose of adjusting or focusing the microscope is to produce a magnified image that is sharp. That is where the problem begins. Do not be surprised if you do not get sharp images at once.
The scientific word for focusing to get a sharp image is RESOLUTION. MAGNIFICATION is the enlarging of an image. Resolution and magnification are two different things. The problem is that you cannot get good resolution and good magnification at the same time.
A microscope may have to be continually adjusted to get a sharp picture. This is especially true when you are viewing living things. They swim up and down in a drop of water. As an organism moves in a drop of water, it will go out of focus. Turn the adjustment knob to bring the image back into focus.
The Limitations of a Microscope
1. Resolution limits magnification.
2. Continual focusing is necessary if the object moves.
3. Image will be upside-down and reversed.

Life Processes
It is usually easy to recognize life, but it is often much harder to define it. All living
things are made of cells. Some organisms are unicellular and consist of only a single cell.
Other organisms are multicellular and are composed of many cells. To determine whether
an object is living or nonliving, biologists have agreed on several characteristics that define
living things. They are referred to as life processes or activities. These life processes
include such activities as growth, metabolism, movement, and reproduction. Living things
also react, or respond, to their environment. The ability to respond to an environment
stimulus is called irritability (no, this word does not mean cranky in this case).
Living things grow. Growth is an increase in size. Most organisms also go through a series of changes called development. The beginning form of an organism may not resemble its adult form. For example, a tadpole does not look the same as an adult frog. Growth in multicellular organisms is due to an increase in the number of cells. Humans begin life as a single cell. However, when they are adults, they consist of even more cells.
Metabolism refers to the chemical activities that are needed for life. Ingestion, digestion, respiration, and excretion are the processes of metabolism. Ingestion is taking in food. The process of breaking down food into simpler substances is called digestion. The breaking down of food particles to release energy is called respiration. For biologists, respiration has two meanings. Respiration occurs at the cellular level when food is broken down to release energy. Respiration is also the process of taking in oxygen and giving off carbon dioxide as a waste gas. In humans, breathing and respiration often refer to the same process. Excretion is getting rid of wastes. Excretion usually refers to the removal of solid and liquid metabolic wastes that are produced during respiration.
Catabolism and anabolism are two processes in living things that are involved in metabolism. Catabolism is the break down of complex substances into simpler substances. Anabolism is the formation of complex substances from simpler substances.
Reproduction is the process of producing new organisms of the same kind. Reproduction of living things can occur asexually, requiring only one parent, or sexually, requiring two parents. Organisms that consist of a single cell reproduce asexually by dividing. Organisms that reproduce sexually contain genetic material contributed from each parent. If a group of living things does not reproduce, extinction of that group occurs.
Living things react to changes in their environment. A response is a reaction to a change. Responding to a change in the environment may increase an organism’s ability to survive.
Organisms must be able to get and use energy in order to survive. Energy is needed to carry out all cellular processes. For example, organisms use energy from food to grow, develop, and reproduce.
Energy flows through individual animals, communities, and the environment. It is passed from one organism to another organism, usually in the form of food. For example, a goat eats the energy from the sun that is contained in the cells of a plant. Man then eats the goat and gets its energy. In this way, energy moves through living systems from one organism to another. The sun is the ultimate source of energy, for most of the organisms that live on Earth, although there are exceptions. Some bacteria for example, are able to use the energy trapped in chemical compounds rather than the energy from the sun as plants do.
Living things are highly ordered. A tree grows into a form typical of its species. All humans have the same general form, although there are differences in size. The chemical reactions that occur in living things do not occur randomly. The chemicals that make up living organisms are, in general, more complex than the chemicals found in nonliving things, such as rocks. All living things are complex. All are composed of small units of life called cells. Cells are able to carry out all the life processes that insure their survival.

Biology: An Introduction
Biology is the science that studies life and living things, including the laws that govern
the phenomena of life.
Every aspect of life from the smallest submicroscopic living particle to the largest and most imposing of plant and animal species is included in the study of biology. Biological study encompasses all that is known about any plant, animal, microbe or other living thing of the past or present.
Biology is a natural science because it is the study of organic (living) nature. It is the science of fishes and fireflies, grass and grasshoppers, humans and mushrooms, flowers and sea stars, worms and molds. It is the study of life on top of the highest mountain and at the bottom of the deepest sea. Biology is the accumulated knowledge about all living things and the principles and laws that govern life. Those who specialize in biology are known as biologists or naturalists, and it is through their observations of nature and natural phenomena that the great ideas of biology have been born.
