Lesson 1.10 – Building Models and Proving Mastery

Today’s Learning Targets

• 1.14 – I can explain the development of the atomic model using the contributions of Dalton, Thomson, Rutherford, and Bohr.

Who Will Win Hell’s Atomic Kitchen?

First Step: Research

I. Discoveries of Dalton, Thomson, Rutherford, and Bohr

• Research must be done to identify the contributions of Dalton, Thomson, Rutherford, and Bohr to our current model of the atom.

• Organize the info using the Wikispaces template.

II. Organize and Synthesize• Once all the

research is done and the necessary information is gathered, put it together!

• Tell a story from the beginning of atomic experiments to the current theory.

Second Step: Design

I. Drawings of Dalton, Thomson, Rutherford, and Bohr

• Draw the models proposed by each scientist in a way that will be easy to reproduce in a model on construction paper. Make sure the Bohr Model looks great!

• If you can, make it look shnazzy!

• Mr. Astor loves pretty things!

II. Record Video of Ion Creation on Mr. Astor’s Computer

• Once you’ve determined how to create your atomic model, come to Mr. Astor and record the process needed to create an ion from the neutral atom.

• Astor will save your video for your wikispaces!

Next Step: Build

I. Construction of Dalton, Thomson, Rutherford, and Bohr’s Models

• Paint your totem pole and label your side with chalk!

• Put together models using materials available and attaching it to the construction paper.

• Make sure your model will fit on your totem pole!

II. Take Photos of Finished Models

• Once your work is securely attached to the totem poles, take photos of each stage of construction.

• Organize pictures to begin your atomic theory story that will be told on wikispaces.

Final Step: Capture

I. Create Wikispaces Page to Capture All of Your Stellar Creations!

• Follow Mr. Astor’s Rubric and his exemplar model to create a Wikispaces page that captures all of the contributions to the atomic model in a story!

II. Decorate and Detail • Prepare a compliment sandwich for

each scientist who must be proven wrong to make way for the newest model!

• Channel your inner Gordon Ramsay in an attempt to find the winner for Hell’s Atomic Kitchen!

Work Time• Let’s Get to Work!• Get Cooking!

Closing Time• Finish all practice and stations work by exam

time!• UNIT 1 EXAM Friday (9/19/14)!
