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

4. Atomic Theory Model Development
Use the following videos and this website to learn about the development of the Atomic Model
Activities we did in class for each scientist:
Introduction: The two pieces of tape. How did piece A react when brought in to close proximity to piece B? Another A? How about piece B with another B?
Democritus: Tear a sticky note in half. And in half again. And again until you get to the smallest piece possible. How is this activity similar to what Democritus thought about matter?
Dalton: Shake a small container with whipping cream until it turns into butter?
Thomson: Rub a balloon on your hair. Now stick it to the wall. Then next to water. Then next to a paper. What do you observe?
Rutherford: Clay ball exploration (do this in Mrs. Clark's room)
Bohr: Complete the sheet that goes with Bohr (#5 above). Look up "hula hoop atom model" online to help.
Electron Cloud: Watch the video. If the "reflection" portion write about the experiments they did. In the "analogy and interpretation" portion write about what happened when the electron was observed.
Use the following videos and this website to learn about the development of the Atomic Model
- Video clip reflection: watch the video that goes with each scientist and write what you learned about their model as well as how they developed that model.
- Model: write the name of their model
- Analogy & Data Interpretation: describe how the activity in class is similar to what the scientist did to learn about atom.

6. How Small is an Atom?
Watch the video and write details about the following analogies:
|
|
|
7. Atoms
in a Dish Use the simulation to the right to create atoms. Fill in the key on your paper, then create each of the first 10 elements and fill in the table on your paper. (If the simulation does not work for you, then use this document) Next, list the strengths and limitations of this simulation. Lastly, list relationships that these models show about scale (size), proportion (ratios) and/or quantity (amount). |
|
7.5 Making a Model of an Atom
|
If you were absent, use items in your own home to create a model of one of the elements from the period table of elements. Draw it on the back of your "Atoms in a Dish" paper. Show me in class. Include: the number of protons, electrons and neutrons, and a description of the strengths and limitations of your model.
|
8. Making Molecules In class we used gum drops. If you were absent, run the simulation to the right (can not be done in chrome) and make the molecules on your assignment. Another option (still needs java): http://www.molecularium.com/kidsite.html |
9. Quiz 8.1.1 Must be completed in class. You can retake it before or after school. KAHOOT Review
Test/Assessment 8.1.1 Please complete on Canvas. Access code: atomsrule
|
I can obtain information about various properties of matter.
I can evaluate how different materials’ properties allow them to be used for particular functions in society. I can communicate my findings. |
|
10. Powder and Sand Lab |
Left video: White Powder Right video: Colored Sand
Watch the video and fill in your Lab paper. Pause before each substance is added to the water and make at least one observation in the "Findings" section. Then watch the rest of the video and fill in the rest of your Lab paper. |
|
|
12. Mystery Liquids |
In class we tested 4 mystery liquids to find out about their properties. In the left column on your paper, write down the tests that we did, then use google to find out the information about each liquid. Then answer the questions on the back of the assignment.
Tests: flammability, pH, reaction with baking soda, smell, surface tension and density. Liquid A -- Mineral Oil Liquid B -- Rubbing Alcohol (70%) Liquid C -- Distilled white vinegar Liquid D -- Water |
13. Chemistry Alien Periodic Table Patterns
|
Use the picture below to complete the Alien table worksheet including your predictions of the two missing aliens.
Then, complete the back side of the worksheet by using this PowerPoint and watching the videos below. |

|
14. Objects and Their Properties
|
The five objects we looked at in class were: 1) Pencil, 2) Ziploc plastic sandwich bag, 3) a bracelet glow stick, 4) hand warmer, and 5) a rubber band. Write at least 3 structures that each item has. Then circle one and tell how that structure leads to its function.
On the back of your paper, choose an item (headphones, chair, refrigerator, skate board, flip flop, etc.). Do a little research on the internet, if needed. Write down at least 5 structural properties (characteristics). Then explain each structure's function. |
Obtain information about your assigned element by visiting the websites to the right. (If you were absent, use a random number generator to choose an element for you, 1-60)
Evaluate that information and determine whether you will create a Super Hero or a Villain and what its special powers are. Draw a picture and label it with the necessary information (see assignment page) Prepare to communicate your finding in a 60 second in-class presentation. BELOW ARE SOME EXAMPLES |
|
I can plan and conduct an investigation.
I can analyze and interpret the data to identify patterns in changes in a substance’s properties to determine whether a chemical reaction has occurred. |
|
|
|
|
17. Introduction to Chemical Reaction Patterns
|
What is a chemical reaction? How do you know if a chemical reaction has occurred?
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. |
|
|
|
|
|
|
|
|
|
|
This PhET simulation shows how the atoms rearrange to form a new substance. |
|
18. Chemical Reaction or NOT?
Watch the videos and decide whether a chemical reaction occurred, or NOT. Provide evidence!! Some videos have more than one experiment--just record as many as you need to fill your paper.
Complete the "Claim it!" section of your worksheet by choosing 5 of the demos and inferring whether they were a chemical reaction or not. Be sure to include your evidence (indicators).

23. Natural vs. Synthetic
|
Determine of the following items are natural or synthetic and record your finding on the worksheet.
rubber, plastics, wood, paper, fabrics (cotton, rayon), glass, metals, sea shells, building materials, medicines, foods (twinkies, carrot, cheese puffs), fuels |
|
|
|
Natural chemicals are produced by nature without any human intervention. According the U.S. National Organics Program (NOP), a natural substance is derived from a plant, mineral or animal source, without having undergone a synthetic process.
Synthetic chemicals are made by humans using methods different than those nature uses, and these chemical structures may or may not be found in nature. A synthetic substance is a compound which is made artificially through chemical reactions.

24. Synthetic Material Brochure |
Choose an item made from a synthetic material. Then create a tri-fold brochure, according to the specifications on the student sheet (see table of contents above) to inform others about your item. Due Tuesday, October 16, 2017.
List of synthetic materials. Once your brochure is completed, use the "share" button to copy and past your link here so that I can print your brochures. Make sure you: A) paste your link on the correct tab for your class period and B) include your name before you paste your link. |
