Chemistry Strand 8.1 Starters
The physical world is made of atoms and molecules. Even large objects can be viewed as a combination of small particles. Energy causes particles to move and interact physically or chemically. Those interactions create a variety of substances. As molecules undergo a chemical or physical change, the number of atoms in that system remains constant. Humans use energy to refine natural resources into synthetic materials. TEXTBOOK

32. Lego Lab
or PhET Lab for the Law of Conservation of Mass If you were absent for the Lego Lab, complete the following (print this worksheet) by using the PhET simulation to the right. |
|
33. Conservation of Mass Lab
If you were absent the day of the lab, use the simulation to the right and these instructions (print this worksheet) to complete the lab. Write your answers on separate sheet of paper. |

I can develop a model to illustrate cause and effect relationships in particle motion, temperature, density, and state of pure substance when heat energy is added or removed.
I can use computational thinking to illustrate cause and effect relationships in particle motion, temperature, density, and state of pure substance when heat energy is added or removed. |
36. Balloon Behavior
Mylar balloon demonstration. We heated a mylar balloon that was partially filled with helium--not enough to float on its own. After heating it, however, it floated. Use this information and the video to the right to fill in the worksheet. On the back of your paper, create a triple Venn diagram for solids, liquids, and gases. |
|
|
38. Phases of Matter Lab Use the pictures at the right to complete the student sheet (see table of contents above). Make sure to look at the comments on each of the pictures.
|
|
39. Heat Curve of Water Lab
Use the video at the right to complete the data table on your student sheet (see table of contents above). Graph the data and answer the questions on the student sheet. Note the following in your observations and on your graph: a) all ice is melted, b) visual distortions form in the water due to thermal currents and density changes, c) first noticeable steam appears, d) bubbles start and e) bubbles form from the center of the water.
The video to the right is in real time. You will need to record the temperature every minute and make observations. |

40. Soap Soufflé What happens to the soap? Why does it happen?
Use the picture below and videos to the right to fill out the Soap Souffle paper. |

42. Introduction to Heat Transfer
|
In what ways is heat transferred? Use the following website and the videos below to conduct some research about heat transfer.
http://www.hk-phy.org/energy/domestic/print/heat_phy_print_e.html If you were absent for day 2 of this activity, go to the following spread sheet to get the data from your class period. Use the data to make a claim. |

If you were absent Thursday/Friday, complete this alternate assignment (print this worksheet and complete it).
44. Bill Nye Day
Watch Bill Nye: Heat (1st video) and answer the questions. Then, watch Bill Nye: Phases of Matter and answer the questions.

Making a Claim
A claim is arguable and can be proven with evidence. |
|
|
|
If you were absent: Watch the videos to the right and read the definitions. Then, watch the videos below. As you are watching list the following for each video:
|
CLAIM: "A claim is a statement of a student’s understanding about a phenomenon or about the results of an investigation; it answers the original question by expressing what he or she is trying to help an audience understand and believe."
EVIDENCE: "While data can refer to all the observations that students have collected or analyzed, data become evidence when used to support a claim. A claim is convincing to someone else only when there is strong evidence to support it. "The evidence for explanations can come from investigations students conduct, from observations they make, or from reports of empirical research others have done." REASONING: "Reasoning illustrates why particular evidence is the correct evidence to use in support of a particular claim. Reasoning typically includes describing the scientific knowledge or theory, or... the Scientific Principle, that applies to a particular claim and evidence." |
