INDIVIDUAL DESCRIPTIONS:

Create a Paper Model of DNA: How this activity works:

Step 1 - Students color the bases, phosphates, and sugar according to the key.

Step 2 - Cut out the individual shapes.

Step 3 - Assemble the DNA model like a puzzle.

Step 4 - Glue to a paper.

Upcycled/Recycled DNA Model Project: FREE BONUS! This resource gives students clear and concise directions to build a DNA model out of upcycled or recycled "stuff". The straightforward directions help all students understand exactly what is required. To spark ideas about "stuff" to use, a helpful list of suggested materials is provided with the directions. A student-friendly, easy-to-follow rubric is also included.

Easy DNA Extraction Lab (for middle school!): No need to make it complicated, this investigation makes it easy on you. There is a quick background section, materials list, procedure, and a quick analysis section. The procedure section includes a quick explanation for each step that describes what is happening at the cellular level (middle school appropriate). The procedure, the analysis questions, and even the format of the worksheet itself are all geared towards the middle school level.

DNA Mutations Activity: In this activity, students will:

• "Decode" a non-mutated message into an English phrase. (The phrase itself is a clever saying about DNA.)
• "Decode" a mutated segment of DNA. The new message says something entirely different, even though only a few DNA bases were off. (The mutated phrase pertains to mutations in DNA.)

Build a Karyotype Activity: In this activity, students will:

• Read clear step-by-step instructions
• Cut out the chromosomes and match up the homologous pairs
• Create a karyotype by pasting the matching chromosomes to their baby
• Determine the gender of the baby by examining the karyotype
• Answer 10 follow-up analysis questions

DNA Fingerprinting Activity: In this activity, students will:

• Read a silly (not scary) murder mystery. The scene is set for students to figure out who killed Mr. Henry Lord Whippleton. There are two suspects... and one of their DNA fingerprints will match the DNA found at the crime scene!
• Get an introduction to DNA fingerprinting with a 1-page introduction and a tiny bit of practice.
• "Process" the two suspects' DNA (involving cutting and pasting paper DNA strips) to make a DNA fingerprint for each suspect.
• Compare the DNA fingerprints they have generated to the one found at the crime scene. Mystery solved!

All answer keys are included.
