Lesson 1
DNA Extraction Lab
Lesson 1: Conduct the experiment. Gather the supplies need - a fruit (2 strawberries, or a banana, or frozen fruit thawed to room temperature). I will be using 2 strawberries. Then you will need 2 cups, 2 teaspoons of soap, one teaspoon of salt, 1/2 of a cup of water, a coffee filter, a straw or stirring utensils such as a fork, and 1/2 cup of rubbing alcohol *some students improvise by diluting some hand sanitizer with water*.

Lesson 2
Building blocks of DNA
Lesson 2: In this lesson, you will learn about the building blocks of DNA- nucleotides, phosphates, sugars, and nitrogenous bases. We will practice naming the parts of DNA and complementary base pairing. You will complete a Google Form and an interactive game. You will be provided individual feedback for your form and game. Additionally, you will be asked to answer an exit ticket question on our Outschool Classroom page and ask any questions you have before you move forward.
 Week 3
Lesson 3
Purpose of DNA
Lesson 3 will discuss the purpose of DNA for living things. What is stored in our genetic material, where is it stored, and how is it stored. You will answer a few exit questions reflecting back to the lab to describe what your DNA looked like as well as checking your comprehension of the content.
 Week 4
Lesson 4
DNA Replication and Mutations
Lesson 4 will discuss DNA replication and potential errors that could occur. We will end our lesson with a final interactive review game of the entire class and reflecting on our lesson/lab. A hyperdoc will be provided that include my class videos, interactive games, activities, area for guided notes, exit ticket and any other resources used for class.
