However, all protists are too tiny to see without magnification of at least x. To look at protozoa with a compound microscope, use a medicine dropper to put a drop of pond water onto a concave slide.
Cover the drop with a slide coverslip , and then view the slide on high power. What kind of detail do you see? Can you identify different kinds of protists? What physical characteristics like flagella or pseudopods can you see? But what is a virus? It has two main characteristics: its genetic material DNA or RNA is encased in a protective protein coat, and it is unable to reproduce itself the way cells can.
Because of this inability, viruses are considered to be non-living. So how does a virus work? They are often able to cure once-fatal diseases, such as the bacterial infection scarlet fever.
Amoxicillin, penicillin, and erythromycin are common antibiotics that inhibit bacterial cell functions. Antibiotics are derived primarily from bacteria or fungi mold , such as Penicillium.
Malaria is a disease caused by protozoa that are carried by certain mosquitoes. Antibiotics, such as doxycycline, can be used in both treatment and prevention of malaria. In some cases where an antibiotic is used to treat a disease, the disease-causing bacteria or protozoa will develop resistance to the drug, meaning that that particular antibiotic will no longer be effective at destroying the resistant organisms.
Antibiotic research is a continuous process, since the need often develops for bigger and better antibiotics to wipe out resistant diseases. You need vaccines to prevent viral diseases such as hepatitis or polio. A vaccine is a weakened form of a disease, which produces antibodies when injected in a person or animal. These antibodies allow the immune system to recognize and attack a stronger form of the disease. After you finish this article, we invite you to read other articles to assist you in teaching science at home on the Homeschool Hub, which consists of over free science articles!
Home Science Tools offers a wide variety of science products and kits. Find affordable beakers, dissection supplies, chemicals, microscopes, and everything else you need to teach science for all ages! But, we can help. Is STEM just another fad?
Or are STEM fields the key that can unlock the future for not only young people but for the world? Let's dive in. Science can be split up into several fields of study. They shared what they learned in public service announcements PSAs , which were posted around the school buildings.
While the activity was originally planned for in-person instruction, students were still able to collaborate with their peers from a distance using digital tools like Jamboard, says Kearney. Social distancing: As states reopen schools for in-person learning, teachers and students are gearing up for ways to safely return to the classroom. Second-grade teacher Melissa Collins of John P. To show what they learned, they could make a skit, write a poem, or create a prototype.
Students familiarized themselves with COVID facts, considered which cell organelles their virus-buster would use to imitate real cell behavior, and sketched out a rough prototype of the nanobot on their iPads.
How viruses spread: Jennifer Sweaks, a biology teacher at Allen High School in Texas, developed a multitiered lesson plan that reflected the progression of the pandemic. In addition, they completed an interactive simulation called Gizmo this lesson was free, with an account , focused on disease spread, and explored the transmission and treatment of HIV using research studies by the National Institute of Allergy and Infectious Diseases. To incorporate multimedia, Sweaks created lesson plans on TEDEd that showcased how viruses jump from animals to humans and how funding for virus monitoring programs—and the lack thereof—have impacted global efforts on curbing emerging diseases.
Louis, Missouri, students shared their own experiences with the COVID pandemic and the questions they had about the virus. Students then embarked on a quest to find out about pandemics of the past, how the coronavirus spreads, and how the spread can be contained. Viruses are microscopic parasites that can infect living organisms and cause disease. Viruses can make a copy of itself inside of another organism's cells. Viruses are a nucleic acid with a protein coat. Viruses have a simple structure.
Different viruses cause everything from the common cold to the measles. To help stop the spread of a virus wash your hands often. There are not very many good things about viruses. Viruses usually attack your body and make you sick! Germs are tiny organisms that cause diseases in plants or animals. Germs are microbes or microorganisms that are so small they can only be seen through a microscope.
There are many types of germs including bacteria, viruses, protozoans, and fungi. Germs are more like little bugs then dirt because they are microorganisms or tiny living things. Many medicines stop disease by killing germs. Diseases caused by bacterial germs are called bacterial diseases and those caused by virus germs are called viral diseases. We are all exposed to germs everyday, but it helps our body build stronger immune systems to fight off diseases in the future.
Bacteria live all around us in colonies and reproduce quickly. Bacteria are single celled microorganisms that live in the air and even in our bodies.
