action potential: A brief change in electrical potential on the surface of cells, particularly nerve cells and muscle cells, triggered by stimulation, leading to the release of electrical impulses.
agriculture: The cultivation of plants, animals, and fungi to fulfill human needs such as food, fuel, chemicals, and medicines.
cell: The smallest functional unit in an organism, consisting of a fluid enclosed by a membrane or wall, usually invisible to the naked eye. Animals are composed of thousands to trillions of cells, while some organisms like yeast, molds, bacteria, and certain algae consist of a single cell.
chemicals: Substances formed when two or more atoms combine in specific proportions and structures, such as water, with a chemical formula of H2O resulting from the combination of two hydrogen atoms and one oxygen atom.
crops: Plants intentionally cultivated and harvested by farmers, like corn, coffee, and tomatoes.
cultivate: To prepare land for plant growth or encourage plant growth.
current: A fluid moving in a specific direction, or in electricity, the flow of electricity or amount of charge moving through a substance in a defined time period.
deciduous: Trees or shrubs that shed their leaves each winter and grow new ones in spring.
charge: Physical property responsible for electric force, can be negative or positive.
electricity: The flow of charge resulting from movement of negatively charged particles, usually electrons.
electrode: A device for conducting electricity and making contact with a non-metallic part of an electrical circuit.
electronics: Devices powered by electricity, with properties controlled by a semiconductor or circuit that regulates charge movement.
engineer: A problem-solver using science and mathematics to design solutions.
environment: Everything surrounding an organism or the conditions and processes resulting from those surroundings.
fungi: Organisms with cells reproducing through spores, feeding on organic matter, like mold, yeast, and mushrooms.
How to walk: Animal foot movement pattern when walking.
materials scientist: Researchers analyzing atomic structures of materials in relation to their properties.
molecule: Group of atoms representing the smallest amount of a compound, made of the same or different atoms, like oxygen (O2) or water (H2O).
nerve: Long fibers transmitting signals throughout an animal’s body.
nutrients: Substances plants, animals, and living things require for survival, like vitamins, minerals, fats, etc.
oxygen: Gas essential for animal and microbial growth and metabolism.
plastic: Materials susceptible to deformation or synthetic materials resistant to deterioration, made from polymers.
potential energy: Energy held by an object due to its position rather than movement.
robot: Machine sensing environment, processing information, and responding with actions.
sensor: Device capturing and transmitting information about physical or chemical conditions.
static electricity: Accumulation of excess charge on a surface without flowing through the material.
synthesis: Creation of something not naturally occurring, like synthetic materials.
taste: Fundamental sense for perceiving environment, particularly food, using taste buds.
technology: Application of scientific knowledge for practical purposes, resulting in devices, processes, and systems.
transparent: Allowing light to pass through to see objects behind, or information revealing the people, processes, or impacts behind something.
ultraviolet light: Light near violet in the spectrum invisible to the human eye.
ultraviolet light: Electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays.
