Thermodynamics
This temperature scale is used universally by scientists because it starts at absolute zero, where all molecular motion stops.
What is the Kelvin scale?
This basic circuit component can safely stop or start the flow of electricity, acting like a bridge that opens or closes.
What is a switch?
This measurement scale from 0 to 14 tells you how acidic or basic a food item is.
What is the pH scale?
This clear, strong-smelling liquid turns a white powder like baking soda into a fizzy, bubbling reaction.
What is vinegar?
This type of heat transfer occurs when warmth moves directly through a solid object, like a metal spoon heating up in a hot bowl of soup.
What is conduction?
This electrical unit measures the push, or electrical pressure, that drives a current through a wire.
What is a volt (or voltage)?
This chemical element, found in milk and dairy products, is crucial for building strong bones and teeth.
What is calcium?
Forensic scientists look at these unique patterns left behind by a suspect’s fingers to solve a crime.
What are fingerprints?
Materials like fiberglass, styrofoam, or vacuum layers that are highly effective at slowing down the transfer of heat are called this.
What are insulators?
This law states that current is equal to voltage divided by resistance, usually written as I=V/R.
What is Ohm's Law?
This common kitchen ingredient is a living, single-celled fungus that consumes sugar to produce carbon dioxide gas, causing bread dough to rise.
What is yeast?
This classic, shiny metal is easily identified because it is strongly attracted to a magnet.
What is iron?
This property refers to the amount of heat energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius.
What is specific heat capacity?
In this type of circuit, all components are connected in a single loop, meaning if one lightbulb breaks, they all turn off.
What is a series circuit?
This chemical test uses a drop of amber-colored iodine solution, which turns a dark blue or black color when it touches a potato or cracker.
What is a starch test?
Unlike real hair or animal fur, this group of clothing fibers includes materials like nylon, polyester, and spandex.
What are synthetic fibers?
This law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed from one form to another.
What is the First Law of Thermodynamics (or Law of Conservation of Energy)?
This specific component is designed to restrict or reduce the flow of electrical current in a circuit, and its value is read using colored bands.
What is a resistor?
This complex carbohydrate consists of long chains of glucose molecules and is the primary form of energy storage in plants.
What is amylose (or starch)?
This lab technique uses water or rubbing alcohol to separate out the different colors hidden inside a suspect's ink pen marker.
What is chromatography?
