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.
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.
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.
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.
Photosynthesis Learn how plants use photosynthesis in order to create energy. Photosynthesis combines sunlight, carbon dioxide, and water to create sugar and oxygen.
Types of Decomposer What is a decomposer, and how do they help ecosystems?
Mitochondria Learn why the mitochondria is called the powerhouse of the cell. The mitochondria helps generate energy for the cell in the form of ATP.
Lysosomes 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.
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.
Steps of the Scientific Method Learn the steps of the scientific method and why are they important.
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.
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.
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.
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.
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.
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.
Vacuoles are storage containers of plant and animal cells.
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,
Your genotype is your genetic code. In mendelian genetics, it can be homozygous or heterozygous. Your phenotype is the physical expression of the genotype. In this video, I give examples of your genotype and phenotype.
The Golgi apparatus is an organelle found in eukaryotic cells. It receives proteins from the E.R. and repackages them and sends to other parts of the cell.
A macromolecule is a large molecule created from smaller elements and molecules combining together. Elements like carbon, oxygen and hydrogen combine in order to make macromolecules. Examples of macromolecules are DNA, proteins, and carbohydrates.
