- Trait
-
Watch the Video: Show the "Adventure Guide" video, which covers the fundamental concepts of DNA and genes. Students should watch carefully as they will use this information to complete the escape room challenge.
Main Lesson (20 minutes)
-
Discussion: Engage students in a brief conversation to ensure they understood the key concepts from the video. Ask simple questions such as:
- What is DNA, and why is it important?
- Can anyone name a trait they’ve inherited from their parents?
-
Quick Summary of Each Subtopic:
- DNA Structure: Explain that DNA looks like a twisted ladder (double helix) and carries the instructions for making all living things.
- Role of Genes: Genes are segments of DNA, and they tell the body how to make proteins, which affect traits like eye color or height.
- Inheritance: Traits are passed from parents to children because we inherit genes from both of our parents.
Activity & Assessment (30 minutes)
-
Escape Room Challenge: Have students begin the online escape room “DNA Island: Escape the Eruption”. This interactive adventure allows them to apply what they learned in a fun, engaging way by solving puzzles related to DNA, genes, and inheritance.

Class Monitoring: As students work through the escape room, walk around to ensure they are staying engaged and answer any questions they might have. Remind them that they can re-watch the "Adventure Guide" video by clicking the provided button if they get stuck.
-
Optional Assessment: If additional assessment is needed, provide the downloadable worksheet for students to complete. This can include questions on vocabulary, identifying traits, or matching genes to traits.
Conclusion (5 minutes)
-
Wrap-Up: Discuss how students did in the escape room, reviewing any challenging concepts. Reinforce the learning objectives by asking students to share one thing they learned about DNA, genes, or heredity.
-
Congratulate the Class: Celebrate their success in escaping DNA Island and mastering the basics of genetics!
Assessment Tools
- Escape Room: Serves as the primary engagement and assessment tool, with students solving DNA and genetics puzzles.
- Optional Worksheet: An additional downloadable worksheet for assessment can be completed as homework or during class for extra practice.

Teacher Reference Guide: DNA and Genes
In this lesson, students will learn the basics of DNA, genes, and heredity through engaging activities and discussions. You will guide them through understanding how DNA acts as the blueprint for all living things, how genes control specific traits, and how traits are passed from parents to offspring through heredity. The lesson will use a combination of direct instruction, an informative video, and an online escape room for interactive learning and assessment. Below is the information you’ll need to convey to your students.
DNA and Its Structure:
DNA, or deoxyribonucleic acid, is the molecule that carries the genetic instructions for all living organisms. It’s often described as a blueprint or a set of instructions that tells the body how to grow, develop, and function. DNA has a unique shape called a double helix, which looks like a twisted ladder. The "rungs" of this ladder are made up of four chemical bases: adenine, thymine, cytosine, and guanine. These bases pair up in specific ways to form the code that determines everything about an organism.
Genes and Their Role:
Genes are specific segments of DNA that carry instructions for making proteins, which are essential for the body's functions and determine an organism's traits. These traits can be physical characteristics like eye color, hair color, or height. Each gene corresponds to a particular trait, and everyone has two copies of each gene, one inherited from their mother and one from their father. Some genes are dominant, meaning they are more likely to be expressed, while others are recessive and only show up if both parents pass down the recessive gene.
Heredity and Inheritance:
Heredity is the process by which traits are passed from parents to offspring. This is why children often resemble their parents or siblings—they inherit genes from both parents. For example, if both parents carry the gene for blue eyes, their child may inherit this trait. Not all traits are inherited equally; dominant genes are more likely to appear in a child’s traits, while recessive genes need to be passed down by both parents for that trait to appear.
Relevant Vocabulary:
- DNA (Deoxyribonucleic Acid): The molecule that holds genetic information and provides instructions for living things.
- Gene: A specific part of DNA responsible for making proteins and determining traits.
- Heredity: The process of passing traits from parents to offspring.
- Chromosome: Structures within cells that contain DNA and genes.
- Trait: A characteristic determined by genes, such as hair color or height.
Video Instruction (Adventure Guide):
Before starting the online escape room, have students watch the "Adventure Guide" video, which will provide all the information they need to successfully complete the escape room challenges. The video explains DNA, genes, and heredity in simple terms that align with the concepts you’ve introduced. Remind students to pay close attention, as they will use this information to solve the puzzles in the escape room. If they get stuck during the escape room, they can always re-watch the video by clicking the Adventure Guide button provided on each question page.
Online Escape Room:
Once the video is complete, direct students to the online escape room, DNA Island: Escape the Eruption. This is where they will apply what they’ve learned by solving DNA and genetics puzzles to advance through the lab before the volcano erupts. The escape room acts as both an engagement tool and an assessment, allowing students to demonstrate their understanding of the material in a fun, interactive way.
Optional Worksheet for Assessment:
If you feel additional assessment is necessary, you can provide students with the downloadable worksheet. This worksheet includes questions that reinforce the key concepts of DNA, genes, and heredity and can be completed during class or as homework for further practice.
By using this guide, you can ensure students grasp the essential concepts of DNA and genes, engage in critical thinking through interactive puzzles, and reinforce their learning through a well-rounded lesson that fits within the one-hour timeframe.
