Who's it for?
This chapter of our Middle School Life Science Tutoring Solution will benefit any student who is trying to learn about microbiology and microbes and earn better grades. This resource can help students including those who:
- Struggle with understanding germ theory, antibiotics, bacteria or any other microbiology and microbes topic
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning about science visually
- Find themselves failing or close to failing their microbiology and microbes unit
- Cope with ADD or ADHD
- Want to get ahead in middle school life science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about microbiology and microbes simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about microbiology and microbes on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Learn about the Germ Theory of Disease and discover how the Theory of Spontaneous Generation was disproved by Louis Pasteur
- Explore the development of vaccines and antibiotics
- Note the contrasts between prokaryotic and eukaryotic cells
- Define archaea and bacteria
- Describe the characteristics of cyanobacteria, fungi and protozoa
- Provide examples of algae
1. The Germ Theory of Disease: Definition & Louis Pasteur
In this lesson, we will look at one of the most influential experiments in the field of microbiology. We will learn how Louis Pasteur disproved the theory of spontaneous generation which helped lead to the development of the germ theory of disease.
2. Antibiotics and Vaccines
Do you know why children must get regularly vaccinated? Have you ever wondered how an antibiotic works and why they are so widely prescribed? If so, this lesson will help you to understand how changes in medicine have almost eliminated several deadly diseases and added decades to the average person's lifespan.
3. Archaea: Definition, Characteristics & Examples
There is an entire domain of life that is made up of single-celled organisms without nuclei. We're not referring to the Bacteria domain, however. In this lesson, we will examine the main characteristics of the least commonly known domain, the Archaea.
4. What is Bacteria? - Definition, Characteristics & Examples
This lesson will introduce the Bacteria, a large and diverse group of microorganisms. We will examine several key characteristics, as well as a few commonly known examples of bacterial species.
5. Cyanobacteria: Definition, Characteristics & Species
Cyanobacteria are a phylum of Bacteria that produce oxygen during photosynthesis. This lesson will examine cyanobacteria and the role they played in establishing our oxygen-rich atmosphere.
6. What are Protozoa? - Definition, Characteristics & Examples
Taxonomy is the realm of science that attempts to group similar organisms together, which is not always an easy task. In this lesson, we will examine the protozoa, a diverse group of organisms that didn't really fit anywhere else.
7. What is Algae? - Definition, Characteristics & Examples
Plants are not the only organisms capable of carrying out photosynthesis. In this lesson we will look at algae and how an algal species can be differentiated from other organisms and microbes.
8. What are Fungi? - Types and Characteristics
In this lesson, we will examine the group of organisms known as the fungi. This group includes the familiar organisms mushrooms, yeasts and molds. We will look at several major characteristics of fungi, as well as a few disease-causing fungi.
9. Broth Culture: Definition, Medium & Characteristics
Broth cultures are used by scientists to grow bacteria. Learn why broth cultures are used, some characteristics of bacteria in broth cultures, and the different types of media available.
