** TEKS**

**Eighth Grade**

(1) Number, operation, and quantitative reasoning. The student understands that different forms of numbers are appropriate for different situations. The student is expected to:

(D) express numbers in scientific notation, including negative exponents, in appropriate problem situations;

(2) Number, operation, and quantitative reasoning. The student selects and uses appropriate operations to solve problems and justify solutions. The student is expected to:

(A) select appropriate operations to solve problems involving rational numbers and justify the selections;

(B) use appropriate operations to solve problems involving rational numbers in problem situations;

(C) evaluate a solution for reasonableness;

**Timeline**: 2-3 days

**Instructional Focus**: Scientific Notation and Standard Notation

**Hook**:

**Driving Question(s):**

How big is an individual virion of influenza virus? What is a nanometer in comparison to centimeters? Use the diagram above to write the diameter of a typical flu virus in scientific notation. Then estimate the area of a typical flu virus. (Hint: Treat the virus as a circle).

**Challenge Brief Details: The Task**

- Students will research the following the size of the influenza virus. How small is a nanometer.
- Students will write their findings in standard notation and convert them into scientific notation. They will convert the diameter of a influenza virus into centimeters from nanometers.
- Students will compute the area of a typical flu virus in both Standard form and Scientific form.

**Learning Outcomes/Problem Requirements:**

Students will create a poster board illustrating graphically, pictorially, and arithmetically their finding of the diameter of a typical flu virus in scientific and standard form. The poster will include the area calculations of a typical flu virus in scientific and standard form as well.

**Assessments**:

- Versa Tiles – Scientific Notation (modified)
- Scientific Notation Practice
- Scientific Notation Word Problems
- Presentation of their findings and solutions with Pictures of a typical flu virus.

**Resources**:

- Internet Search Engines

**Teacher Notes**:

- Rubrics –teacher created can be utilized
- Personally, I have the students create the rubric, I suggest the items we’d like to grade- information, did they solve the problem, research, creativity, etc. They are to decide the point system and categories they wish to grade each other on.
- I and the students grade each group with the agreed upon rubric they created.
- During the research phase and putting their items to be completed for presentation is graded on a check list of the soft skills we grade the students on.
