You are completing an experiment as measure a block having the mass of 22 grams. Then, in the graduated cylinder filled to 10 mL, is displaced to 28 mL when the bock was placed into the solution. What is the density in sig figs. and with units?
What is 1.222222 = 1 g/mL
300
Science is supported by evidence gathered from observations of the natural world meaning science is empirical. Name a scientist that worked on the atom and how he/she gathered evidence.
What is an example Thomson developing the plum pudding model, explained by his experiment (evidence) using the cathode ray tube.
400
His atomic model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun.
Who is Niels Bohr?
400
It is the description of the following: 4p6 The coefficient 4 represents ______ The p represents _____ The superscript 6 represents_____
What is The coefficient 4 represents the principle level or period. The p represents the orbital the electrons can be found. The superscript 6 represents the number of electrons in the orbital.

When an electron gains an electron current or is heated, the electron changes to this type of energy state. The energy is being _____ in the atom.
What is the electron move to excited energy state and the energy is being absorbed?
400
Two examples of both a chemical change and physical change. The difference between intensive and extensive properties.
What is chemical: rust, reaction Physical: Cereal and milk, tearing up paper, boiling point. Intensive: Amount does not matter Extensive: amount matters

The explained difference between inference and observation with an example of each.
What is observation was you gather from your five senses. Inference is the reasoning or explanation of your observation.Example: Suzie Q is Observation: wearing a sweater, inference: because she is cold.

He theorized that atoms have their charge concentrated in a very small nucleus after conducting his experiment (in your question say the name and his experiment).
Who is Rutherford?

Definition of a solution, element, and a heterogeneous mixture. An example of each.
What is Solution: uniform state of matter with two substances (ex. salt water). Element is a material which cannot be broken down or changed into another substance using chemical means(ex. Oxygen). Heterogeneous mixture: omponents of the mixture are not uniform or have localized regions with different properties (m&ms and Hershey kisses in a jar)?

Science is culturally embedded. In the article we read on Tuesday about Led lights, connect how Led lights are related to quantum energy.
What is the light emitted by LED lights is related to the electrons going from excited energy state to ground state and emitting a photon.
