Science Skills
You should almost always wear these in the lab when doing experiments.
What are (safety) goggles?
These are the three phases of matter.
What are solid, liquid, and gas?
These are the three subatomic particles that make up an atom.
Like charges ___________
Opposite charges ___________
Repel
Attract
This is the term for the highest point on a transverse wave.
What is the crest?
You use this tool to find an object's mass.
This is the characteristic of a substance that can be measured or observed without changing its identity.
What is a physical property?
These are the three element types on the periodic table.
What are metals, nonmetals, and metalloids?
This type of circuit has more than one path for current to flow.
What is a parallel circuit?
This is the term that measures from one point on a wave to the same point on another.
What is the wavelength?
These SI units are used for volume, length, and mass.
This is the change from a liquid to a gas (describe the change in temperature and explain how the particles react).
What is vaporization or evaporation?
(Temperature increases as the particles gain more energy, moving around faster and faster until there is a phase change)
Trail mix, salads, snow globes, and italian dressings are all an example of these.
What are heterogeneous mixtures?
What is a series circuit?
This type of signal lasts longer, can be reproduced many times, and uses the least amount of storage.
What is a digital signal?
This is the place where you read volume on a graduated cylinder.
What is the meniscus?
This is the ability of a substance to dissolve.
What is solubility?
What is the Law of Conservation of Mass?
It states that mass is neither created nor destroyed in chemical reactions.
(The mass of the reactants is equal to the mass of the products)
These are ways to increase the strength of an electromagnet (at least 2 answers).
What are adding more turns and increasing the voltage/current?
These properties of a wave mean it has a higher energy (describe amplitude, frequency, and wavelength).
What are a higher amplitude, a higher frequency, and a shorter wavelength?
Cutting something in half or melting it does not change this physical property.
What is Density?
These are the five points that are indicative of a chemical change. (List at least 3)
- change in temperature
- change in color
- formation of a precipitate
- formation of a gas
- development of an odor
Which type of mixture is homogeneous, has medium sized particles, and does not allow light to pass through?
This term describes something that is only magnetic when placed into a magnetic field.
What is an induced magnet?
This is the mnemonic device to help remember the Electromagnetic Spectrum (list the mnemonic device as well as the names of the types of radiation).
This is how the Electromagnetic Spectrum is organized.
What is Raging Martians Invaded Virginia Using X-ray Guns?
Radio wave, Microwave, Infrared, Visible light, Ultraviolet, X-ray, & Gamma rays.
What is by wavelength?
