Middle School Life Science and Biology

In addition to Math videos I also create animated Life Science and Biology Videos
A beginners guide to the metric system. 

The metric system is a system of measurement used throughout the world, and the scientific community.
It is based on tens, and can be easy to use.

Alleles are different forms of the same trait. Let's look at hair color. You can have black hair color or blonde hair color. The allele is the different color hair and the hair is the trait. You get half of the genetic material from the female an half from the male.

Arthropods Characteristics: Learn what make this class of organisms unique

Biotic and Abiotic Factors

Biotic factors are factors that are alive. This means they can grow,reproduce,use energy, and are made of cells. Abiotic factors are not alive. A rock is an abiotic factor, and a dog is classified as biotic. 

Characteristics of Living Things

What makes something alive? All living things are made of cells, have the ability to grow,reproduce, contain genetic material, respond to their surrounding, and use energy. In this video I give examples of each characteristic of living organisms.


During prophase the DNA, found in the nucleus will condense into rod shaped objects called chromosomes. Humans have 23 chromosomes. In the video I discuss sister chromatin, howchromosomes form and more information.

Connective Tissue 

Examples include bones,cartiladge, and blood

Diffusion-Real Life Examples

On earth objects tend to move from an area of high concentration to an area of low cncentration. This movement from high to low is diffusion. In this video I review several examples of diffusion we encounter in everyday life.

Genotype vs Phenotype

Your genetic code which is referred to as your genotype determines your physical appearance or phenotype. 

Golgi Apparatus

The Golgi apparatus is part of a transportation and repackaging system found in eukaryotic cells.


Heredity is the passing of traits from one generation to the next. 
If you parents have red hair there is a good chance you will have red hair.


Heterotrophs are individuals that cannot create their own energy but must directly or indirectly get their energy from autotrophs.

Interactions in an Ecosystem

In an ecosystem you have several types of interactions including, competition,predator and prey, and sybiosis.

Kingdom Fungi

The kingdom fungi includes mushrooms and lichen. This kingdom is made up of unicellular and multicellular organisms that are heterotrophs. 

Kingdom Monera

The kingdom monera is made up completly of single celled organisms. This kingdom contains bacteria and archaebacteria which are found everywhere on Earth.

Levels of Organization-Cells-Tissues Organs

Organisms have levels of an organization. Groups of cells create tissues. Groups of tissues create organs, and organs create organisms. Finally, organ systems work together to create an organism.

Life Science-Biology

Life Science is the study of life on earth. It includes genetics, anatomy, ecosystems, biomes, and many more fields of study. In this video I review the entire middle school year of life science in three minutes


The liver is one of the most important organs in your body. It is a factory, a storage area, and manufacturing plant.

Lung Facts

Learn interesting and unusual facts about your lungs. Your lungs supply important oxygen to each cell and help remove dangerous carbon dioxide.


Macromolecules are large molecules like proteins, lipids and nucleic acids like DNA


The mitochondria is considered the powerhouse of the cell. It is the site of cellular respiration that creates glucose of the cell in order to give the cell energy.

Nitrogen Cycle

In this video I review the steps of the nitrogen cycle.

Phosphorus Cycle

In this video I review another important cycle called the phosphorus cycle.

Physical and Chemical Changes

Physical changes are changes in appearance only. A chemical change creates a new substance with new properties.


Ribosomes are called protein factories. They are very small organelles found in a cell that make proteins.

Science Crossword puzzles with answers

I create science crossword puzzles almost everyday. Each puzzle has a downloadable pdf and answer key

Six Kingdoms of Life

In this video I review the six major kingdoms. Kingdom anamalia,plant,fungi,bacteria,protist and archaebacteria.


Traits are characteristics that can be passed from one generation to the next. Examples include eye color, face shape, are just two examples.

Types of Decomposers

In this video I review several types of decomposers. They include bacteria, fungi, and insects.


Vacuoles are storage containers of plant and animal cells.

Earthworm Digestive System

Learn how an earthworm digests the food it eats from start to finish

Types of Heterotrophs

Learn about four main types of heterotrophs. Carnivores,omivores,herbivores, and saprotrophs

Life Science Videos for middle School

Life Science is very similar to a basic biology class. Life is fascinating and learning about how life works on Earth can be really fun and interesting. When the flipped classroom came along I started making short animated science videos to help my students in science. I recieved very positive feedback from my students and I feel it really helped them in class. I alternate between creating science videos and math videos. You can find all of my videos at my YouTube channell called,  

MooMooMath and Science
Autotroph vs Hetertroph 

In this video I show how an autotroph is different than a heterotroph. You may have heard these described as producers and consumers. Both autotrophs and heterotrophs play important role in any ecosystem.
Cellular Respiration

How does a cell produce energy in order to stay alive? Both plants and animal cells use cellular respiration in order to generate energy in the form of ATP.

 Characteristics of Living Things  

What makes something alive? In this video I review the characteristics that all living things have.

Decomposer vs Scavenger 

How is a scavenger different than a decomposer? 
Both scavengers and decomposers are important for ecosystems. They both help recycle dead and decaying matter back into an ecosystem. 

Left Hemisphere and Right Hemisphere of the brain 

The brain has a left and right hemisphere. The left hemisphere controls movement on the right side of your body and the right hemisphere controls the left side. In addition the left, the brain is made up of 4 lobes, the brain stem, and the cerebellum. 

Learn why lysosomes are important to the health of a cell. Lysosomes contain digestive enzymes that help the cell break down items in the cell.

Learn how plants use photosynthesis in order to create energy. Photosynthesis combines sunlight, carbon dioxide, and water to create sugar and oxygen.

Steps of the Scientific Method 

Learn the steps of the scientific method and why are they important.
Cell Transportation  

How do cells move important materials into and out of the cell? In this video I explain how cells use active and passive transport to move materials in and out of the cell.
