Cells are the basic units of life that make up all living things. They carry out three basic life processes: nutrition, reproduction, and sensitivity. Cells contain organelles that carry out different functions - the membrane controls what enters and exits, the nucleus controls the cell, and the cytoplasm contains organelles and carries out their functions. Cells are organized into levels with cells forming tissues, tissues forming organs, and organs forming systems. There are different types of tissues including blood, muscle, bone, nervous, fat, and epithelial tissues that have specific functions like movement, support, information transport, storage, and protection.

Tissues organs and systems r2
Multicellular organisms like humans are made of cells that differentiate and organize into different levels. Individual cells specialize and combine to form tissues. Tissues work together to form organs, and organs systems are groups of organs that perform major functions. This allows multicellular organisms to be larger, live longer through cell specialization, and continue living even if individual cells die.

cell.pptx
The document defines the cell as the structural and functional unit of living organisms. It describes cells as the smallest units that make up tissues and organs, which work together in biological systems. The structures of cells include a cell membrane, cytoplasm, nucleus, and organelles. The cell membrane supports and protects the cell, controls movement of substances in and out, and separates the cell from the external environment. The nucleus contains DNA and sends signals for cell growth, maturation, division, and death. Organelles like the mitochondria and endoplasmic reticulum perform specific functions to carry out life's processes. The cell theory states that all living things are made of cells, cells arise from pre-existing cells, and the cell is the basic
Cells and cell specialization
This document discusses cell structure and specialization. It defines cells as the basic unit of life and identifies their main parts as the nucleus, cytoplasm and cell membrane. The document explains that while all cells share these basic components, they come in many shapes and forms due to specialization. Specialized cells take on specific functions like transporting oxygen (red blood cells), movement (muscle cells), and defense (white blood cells). The adaptive features of different cell types allow organisms to carry out vital processes through systems of specialized cell types working together.

Forests are classified as Atlantic or Mediterranean based on climate. Grasslands are located in mountainous humid areas. Deserts and steppes are found in dry, extreme climate regions. Aquatic ecosystems can be marine or freshwater. Marine ecosystems include sandy beaches, rocky shores, and open sea, and are classified based on their salinity. Freshwater ecosystems include rivers and lagoons. The document also discusses threats to these ecosystems and ways governments protect the environment.
Science Matter and energy
This document provides an overview of 6th grade science concepts about matter and energy. It defines matter as anything that has mass and takes up space, and describes the three states of matter - solid, liquid, and gas. It explains that matter is made up of pure substances or mixtures. Mixtures can be separated using various methods like filtration, evaporation, distillation, or decantation. Changes in states of matter, like melting, boiling, condensation and solidification, occur when matter is heated or cooled. It also introduces different types of energy like mechanical, chemical, electrical, light, nuclear, and thermal energy. Energy can be either potential or kinetic.
UNIT 5: ECOSYSTEMS
An ecosystem is made up of living and non-living things that interact in a specific area. Living things include plants and animals, while non-living components are the physical environment. Ecosystems can be terrestrial like forests or grasslands, or aquatic like freshwater or saltwater. Within each ecosystem, organisms fill different roles - producers like plants make their own food, consumers eat other organisms, and decomposers break down dead material. These relationships form food chains and webs that drive energy and nutrient flow through the system. Different species also interact through mutualism, commensalism, parasitism, and competition.
ANIMALS 3RD
This 3rd grade science document discusses animals under four topics: skeletons, birth, food, and movement. It describes that vertebrates have skeletons while invertebrates do not. For birth, some animals are viviparous and give live birth while others are oviparous and lay eggs. In terms of food, animals can be herbivorous and eat plants, carnivorous and eat meat, or omnivorous and eat both plants and animals. Finally, the document lists different ways animals move including walking, flying, crawling, and swimming.
PLANTS 5TH
Plants need water, minerals, carbon dioxide, sunlight, and chlorophyll to grow through the process of photosynthesis. Roots absorb water and minerals from the soil which travel through the xylem vessels to the leaves. Leaves take in carbon dioxide through stomata and use the chlorophyll and sunlight to transform the raw sap and carbon dioxide into glucose. The glucose is then transported throughout the plant via the phloem vessels to provide nutrients and energy for growth and survival. At night when photosynthesis stops, plants release carbon dioxide.
Reproduction 6TH
This document outlines a 6th grade science unit on human reproduction. It introduces key vocabulary words related to sexual and reproductive anatomy and the reproductive process. It provides diagrams and descriptions of the main female and male reproductive systems and their parts. It explains the female and male sex cells (ova and spermatozoa) and their production. Puberty and its physical and emotional changes are briefly discussed. Fertilization, embryo development, the placenta and umbilical cord are summarized. The process of childbirth and delivery of the baby through the birth canal is described.
Keeping healthy
The document discusses different food groups and maintaining a healthy lifestyle. It identifies carbohydrates, dairy, fats, proteins, vitamins and minerals as key food groups. It emphasizes eating a balanced diet from these food groups and limiting unhealthy fats. Maintaining hygiene, getting enough rest, and regular exercise are also presented as important factors for overall health and preventing illness.
Nutrition II
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through arteries and veins, and into over 60,000 miles of capillaries that reach every cell. Blood carries oxygen, nutrients, hormones, and waste products. It contains plasma, red blood cells, white blood cells, and platelets. The kidneys and sweat glands help remove waste from the blood through urine and sweat. Proper hydration through drinking water is important for the circulatory system to function effectively.
UNIT 2 Sensitivity
The document summarizes key aspects of the nervous system and senses. It discusses how the nervous system is made up of the central nervous system (brain and spinal cord) and peripheral nervous system. It captures information from the five senses through sense organs like the eyes, ears, nose, tongue and skin. This sensory information is sent to the brain via sensory neurons. The brain then interprets the information and sends signals to the rest of the body using motor neurons to coordinate responses. The nervous system controls everything we do through reflex actions and voluntary movements.

It also covers topics related to living things like nutrition, sensitivity, reproduction and the stages of human growth from childhood to old age.
Inside your body pwp
The document summarizes the major systems and processes within the human body. It describes the digestive system which breaks down food through a multi-step process involving the mouth, esophagus, stomach, small intestine and large intestine. It also outlines the respiratory system which inhales oxygen through the nose and mouth into the lungs and exhales carbon dioxide. Additionally, it discusses the circulatory system which transports blood around the body through arteries, veins and capillaries connected to the heart. Finally, it briefly introduces several other body systems including the excretory, sensory, skeletal, muscular and reproductive systems.
Power Point Science
This document provides information about nutrition and the digestive and respiratory systems in 3 paragraphs or less:
Nutrition involves the processes that supply our bodies with building materials and energy through food. Foods provide nutrients like minerals, proteins, water, vitamins, fats, and carbohydrates. Carbohydrates provide immediate energy while fats supply slower energy and are stored as reserves. Proteins are needed for growth and repair, while vitamins and minerals aid health and growth.
Digestion breaks down food for absorption. The digestive system involves the mouth, esophagus, stomach, small intestine, and large intestine. Food is broken down by teeth, saliva, stomach acids, and intestinal juices before nutrients are absorbed in

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
