Instructional Segment 1- 7th grade IntegratedMain Learning Goal: Develop models to describe the atomic composition of simple molecules and extended structures.
Focus Question: How are objects made from different types of atoms that range in size? Learning Targets:
Cross Cutting Concept Ideas: Pattern- How are electrons arranged? Is there a pattern to how the elements are arranged on the periodic table? Cause and Effect- If sodium and chlorine come in contact with each other, what happens? Scale, Proportion, and Quantity- What proportion of nitrogen is there in an ammonia (NH3) molecule? How many different elements are in a glucose (C6H12O6) molecule? Systems and Systems Models- How does hydrogen and oxygen combine to make water? Energy and Matter- How can we identify something as matter? Structure and function- How is the periodic table structured? What function does the periodic table provide? Stability and Change- Why is an element considered stable or unstable? |
Performance Expectations for Instructional Segment 1:
MS-ESS3-1 MS-PS1-1 MS-PS1-3 MS-PS1-4 Key Science Ideas:
Guiding Questions: How does the matter in living and nonliving things differ? How does adding or removing thermal energy affect the physical states of matter? How do interactions at the atomic level help us understand the observable properties of organisms and nonliving matter? |
Lesson 1: Introduction to the elements1. Ask the question: How are molecules used in the real world? Explain using a real-life model with the composition of the molecule(s) found in that object.
|
Lesson 2: Classifying elements Building Atoms
Part II: The Atom
|
Lesson 3: Building Atoms and Element Tiles
|
Lesson 4: Video Connection |
Lesson 5: Reading about Atoms: |
Lesson 6: Octect Rule and Lewis Dot |
Students watched PBS Hunting the Elements video: Part 1.
Then watched PBS Hunting the Elements video: Part 2 (This video took 2-3 class periods to complete). Students completed the following worksheet while watching the video. |
Students will read the modified article "What is an Atom?" from Tim Sharp, as well as information from chem4kids.com and took either Cornell notes or Graffiti notes to gather more information.
|
This is a direct instruction activity, with independent practice at the end.
Background information for the teacher Keep the elements to the first 20 elements. Anything over 20 gets into different "rules". Basic Lesson: Teach Bohr Models first, then Lewis Dot the next day Advanced Lesson: Teach them at the same time. |
Lesson 7: Simple MoleculesTalk about how elements 'stick' together to make molecules.
An element is made up of only ONE type of atom. If there are two or more different types of atoms, it's a molecule. this is a good place to talk about subscripts. For example, H2O has a subscript of 2, meaning there are 2 hydrogens for every oxygen stuck together. Use a Lewis Dot Structure to show how the atoms have bonded. Other good simple molecules would be ammonia (NH3) and methane (CH4). Ammonia and water molecules are mixed together to make a substance known as Windex or glass cleaner. (*Note: This is an anticpatory example for their project coming up) |
Object ProjectAsk: How are objects made from different types of molecules?
Introduce the project using the following guidelines:
|
CER MS-PS1-1I walked my students through this CER step-by-step to help them understand what they were doing and writing in science. I showed them CER: Who Killed Franco? a few times as we went through this process.
Students complete a CER answering the following question: How are objects made from different types of atoms that range in size? I required these parts of evidence" 1. use their object to show the different sizes by counting the atoms. 2. Cited evidence to support their claim from the readings and/or videos and/or websites used in this unit. 3. Their choice of the type of evidence used. After the evidence and reasoning were written, I then showed them how to combine them into a paragraph format. Their instructions: Your final paragraph should have: 1claim 3 pieces of evidence 3 pieces of reasoning that connects your evidence to your claim good grammar |
Extend Activity: 5. Give examples of ammonia found in hair dye (NH3) and methane (CH4).
After CER, show the structure of water (H2O).
- dihydrogen monoxide supports a ban
- The Truth about Dihydrogen Monoxide.
After CER, show the structure of water (H2O).

The Periodic Table: Crash Course in Chemistry: An 11 min video on the discovery of, the man who made it real, and the importance of the PT.
My Fun Studio---Instant design of words, statements, or quotes using the periodic table. Lots of fun to play with!
Periodic Table: The New Periodic Table Song by ASAPScience--- You tube videos of the song written to the tune of the Can Can, in two versions...slow and regular pace. The slow version has the words for students to follow along, and possibly remember the lyrics . The fast version, regular speed, does not contain the lyrics, but is much more entertaining for students. I played both versions MULTIPLE times at their request.
Periodic Videos: Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one.
Science Elements: The American Chemical Society's Weekly podcast series highlighting cutting-edge chemistry news in shorter cuts on high interest topics.
Hunting the Elements- NOVA video about how we came to understand elements. It's the full length video on You Tube.
