Science
The Human body. This is one of the topics that I enjoyed the most. So i'll tell you a little bit about it.!
The Nervous System:The nervous system is divided into two parts. There is 30,000 miles of the nerves that snakes through the whole body. The brain and the spinal cord are the main parts of the nervous system. The rest of the body is called the peripheral nervous system. The latter has two main types of nerves which are the sensory and the motor. The sensory is the one that carries messages to the eyes, skin, ears, and some other sense organs. The motor nerves are the ones that convey signals from the brain to the muscle and thats what makes the body move.
The Brain: The brain is a important part of the body. The brain is located on the top of your head and it is cover or protected by the skull. The brain is one of the most largest and complex organ in the human body. Its made up of more than 100 billion nerves that has a communicate in trillions of connections that are called synapses. The cortex is one of the outermost layer of the brain cells. The brain does not only control what you think or feel or hear or how you learn and remember and the way you move and talk but it also does other things like the brain is the boss or the main part of the human body. The heart is the one that tells our heart to keep beating and it helps our digestion when we eat and also the amount of stress we have. The cells is our brain are called neurons those are the ones that send messages to our body.
The Spinal Cord: The spinal cord is connected from the brain down. The spinal cord send messages down to the body. The spinal cord is a thick white rope that starts below the brainstem and it ends as a thin thread. The spinal cord is the main nerve pathway that is between the brain and the rest of the body. The spine is made out of thirty- three separate bones that are called vertebrae. When you get injured the spine is the one that helps and it protects the spinal cord from getting injured bad. Each of the thirty -one pairs of the spinal nerves contains of sensory and motor neurons. It is through the neurons that messages travel from the body to the spinal cord and the brain and back again. Such as the mammals and the frogs, snakes, fish and birds they have spinal cords and back bones and they are called vertebrates. The animals that dont have back bones or a spinal cord such as worms and insects are called invertebrates.
Weather patterns
This is what you usually see or think of when you have weather patterns. This is one of my best topics that I have personally learned about and understood the most.
Climate: The average recorded pattern of weather at a particular place. Also is the average weather in a place over many years. While the weather can change in just a few hours, climate takes hundreds, thousands, even millions of years to change.
Temperature: The degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

Air pressure: Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth.
Wind: Is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air
-
Climate change: The Earth's climate changes over time because of factors, several only partly understood internal and external to the planet. This all includes the sun's activities. It is also a change in the statistical distribution of weather patterns when that change lasts for an extended period of time.
Cells
This is one of the challenging topics (personally) that we have learned so far and this is what I have studied so far
Euglena: The Euglena is a large unicellular protist which means it has both plant and animal cells. This is because the euglena goes through the process of photosynthesis as plants do but also crawl and eat as animals do. So it is not classified as either.
amoeba: The amoeba also called the amoeboid is a celled organism that has the ability to alter its shape mostly by extending and retracting pseudopods. Another name for the amoeba is the amoebae.
Volvox : The Volvox is a polyphyletic genus of chlorophyta green algae in the family Volvocaceae.It forms spherical colonies of up to 50,000 cells.
Paramecium: The Paramecium is marine cell. It is also a genus of unicellular ciliates, commonly studied as a representative of the ciliate group.
Meiosis: is a specialized type of cell division that reduces the chromosome number in half making four haploid cells each genetically different from parent that gave rise to them.
mitosis: In cell biology mitosis is part of the cell cycle. An example of mitosis is the reproduction of body parts the cells are autosomal this is also asexual reproduction. That is when a cell or organism reproduces itself. The difference between mitosis and meiosis is one has two rounds of genetic separation and mitosis has only one
Animal Cell :This is what we and all animals are made of, hints the name animal cell. As you see it is more circular than a plant cell because we aren't as stiff as a plant.
Plant cell :A plant cell I know this is a plant cell because of the way it is shaped it is shaped this is because plants are the way they are shaped all stiff and i also now that animal cells are more circular.
Organelles: Organelles are the structures inside of cells that have certain functions for what kind of organelle it is. There are two different types of cells Prokaryotes and Eukaryotes, prokaryotes have no nucleus and no membrane bound cells and Eukaryotes have all the things Prokaryotes don't have they have a nucleus all the membrane bound cells some like the mitochondria and the golgi apparatus.

Genetics
this is one of the topics I least enjoyed, but also I learned the most about.
-
Genes: are the things that run in your family and the things that determine what you look like and how you act and even how you laugh. Each cell in the human body has about 25,000 to 35,00 genes. Genes aren't just in humans but they are in animals to. Genes are found on tiny spaghetti looking things that are called chromosomes, and chromosomes are found in cells and cells are found in the body. Chromosomes are found in sets of two and there are thousands of chromosomes in the human body. Chromosomes and genes are made of DNA which is the abbreviation for deoxyribonucleic.

Physics. This is one of the topics that I struggle with the most, but I have learned a little bit about it.
