Science teachers should write learning objectives that communicate and describe intended learning outcomes. Objectives should be stated in terms of what the student will be able to do when the lesson is completed. Objectives should include verbs such as listed in table 25.1 to define specific, observable, and measurable student behavior .
Your students probably just think all bacteria are small, bad bugs. You can introduce your students to bacteria by watching and discussing a video lesson, having them research and present a bacteria, and giving them a quiz.

Bacteria are microbes with a cell structure simpler than that of many other organisms. Their control centre, containing the genetic information, is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid rather than a nucleus.
The “objective” of bacteria is to multiply rather than to cause disease; it is in the best interest of the bacteria not to kill the host.
They have made possible our understanding, at the molecular level, of hundreds of disease-relevant proteins that in turn has enabled rational drug design to improve human health.
We use bacteria as protein factories Bacteria can translate foreign genes into proteins – and scientists have ways to ensure that the bacteria make the proteins in large amounts. For these reasons, bacteria can function as 'protein factories', producing medically important proteins and others.
They are essential to supporting life, with benefits related to digestion, preventing the invasion of disease-causing bacteria, and the synthesis of essential nutrients and vitamins. The microbiome is linked to everything from gastrointestinal health to obesity, arthritis, and Alzheimer's.
Bacteria help degrade dead animals and plants and bring valuable nutrients back to Earth. Some species also help clean harmful pollutants out of the environment in a process called bioremediation.

Bacteria (singular: Bacterium) are single-celled microorganisms. The cell structure of bacteria is much simpler than that of eukaryotic cells. There are no nucleus or membrane-bound organelles in a bacterial cell. Thus, bacteria are classified as “ Prokaryotic cells ”. Learn what are the differences between Eukaryotes and Prokaryotes below:
Bacteria are thought to be the first living organisms on earth, about 4 billion years ago. The oldest known fossils (found in western Australia) are of cyanobacteria, dated 3.5 billion years old.
Let’s do physical exams on bacteria to know more about them! Bacteria are prokaryotes (pro-KAR-ee-ot-es), which means they have no nucleus or membrane-bound organelles (i.e., mitochondria or chloroplasts). Prokaryotic cells tend to be small, simple cells, measuring around 0.1-5 μm in diameter.
In the old taxonomic system, Bacteria belong to the Kingdom of Monera. Now, the consensus of the scientific community is creating a level called the Domain above the Kingdom. There are three Domains and six Kingdoms under this system.
Bacteria are considered the most basic form of life. How can we say that? Let’s first review what is the definition of life. Only living things show all of these characteristics:
Most bacteria are good for you, including the bacteria (referred to as Microbiota) in your digestive system. These beneficial bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen (Cyanobacteria) and other chemicals such as ethanol and methane. Some are used to create antibiotics and vitamins.
A single bacterium is too small to be seen with naked eyes. However, bacteria tend to grow and reproduce as a community, resulting in the formation of bacterial colonies. In the laboratory, we can culture a specimen that potentially contains bacteria in a Petri dish. This Petri dish is coated with a layer of nutritious substance.
Lesson objectives are important in helping teachers describe exactly what knowledge and skills students need to know and be able to do . Once objectives are defined, we can then plan lessons with activities ...
Vague objectives. Vague objectives like “be able to describe the differences between plant and animal cells” are not especially useful to teachers. In fact we often see this same objective at Yr 7, Yr9 and Yr12. From this objective it’s unclear as to what we are teaching.
This tick box approach to lesson observations is a dangerous path to pursue, recognised as long ago as in 1987 by Lee Shulman. I have yet to see any science lesson where sharing detailed objectives at the start of the lesson has really helped learning.
When referring to a bacterium in a paper, the writer should underline or italicize the names in the text. After writing the complete name of a microorganism in the first mention, the genus name can be shortened to just the capital letter. For example, Moraxella bovis can be written M. bovis. The ICSP recommends spelling out the entire name ...
While the Bacteriological Code is often interpreted as the “official” list of valid names for bacteria, the Code only provides guidelines on how bacteria should be named. This allows for disagreement, discovery, and evolution in scientific research. For example, one group of researchers might classify a bacterium to genus A.
A bacterium has a binomial name that consists of two parts: the genus name, which indicates which genus it belongs to and the species epithet. Related: Go on a reading marathon and learn the important aspects of academic writing. Check out this section now!
The first, as you might have guessed, is that different types of bacteria might appear to be the same when their names are abbreviated.
Research can be hard enough without worrying about how to use microbial nomenclature or scientific names of bacteria accurately. Writing bacteria names in a research article can be a big challenge for scientists, as the guidelines change to reflect new discoveries. Moreover, Latin names may be confusing.
Science teachers should write learning objectives that communicate and describe intended learning outcomes. Objectives should be stated in terms of what the student will be able to do when the lesson is completed.
A learning objective contains. (1) a statement of what students will be able to do when a lesson is completed, (2) the conditions under which the students will be able to perform the task, and. (3) the criteria for evaluating student performance.
Learning Objectives. Learning objectives are statements of what you intend to teach or cover in a learning experience. They tend to be. More specific than learning goals. Not necessarily observable nor measurable. Instructor-centered rather than student-centered. Useful in helping you formulate more specific learning outcomes.
Why Write Learning Outcomes? 1 describe to students what is expected of them 2 plan appropriate teaching strategies, materials and assessments 3 learn from and make changes to curriculum to improve student learning 4 assess how the outcomes of a single course align with larger outcomes for an entire program
As a general rule, as the level of analysis becomes smaller, from course to module to assignment, the learning outcomes tend to be more specific and easily quantifiable.
Learning goals are broad statements written from an instructor's or institution's perspective that give the general content and direction of a learning experience. They generally describe what an instructor or program aims to do; i.e., “The curriculum will introduce students to the major research methods of the discipline.”
