Teacher Reference Guide: Photosynthesis in the Kelp Forest
Photosynthesis is the process by which plants, like the kelp in our underwater forest, make their own food. During photosynthesis, plants use sunlight, water, and carbon dioxide to create glucose (a type of sugar) and oxygen. This process is essential not only for the plants themselves but also for animals and humans, as it produces the oxygen we breathe. To better understand this, the lesson will focus on three key parts of photosynthesis: the role of sunlight, the importance of water and nutrients, and the production of oxygen.
The Role of Sunlight:
Plants, such as kelp, need sunlight to perform photosynthesis. They have a special pigment called chlorophyll, found in their leaves (or blades in the case of kelp), which captures sunlight. The sunlight provides the energy needed to convert carbon dioxide (which the plant absorbs from the water or air) and water into glucose and oxygen. The glucose serves as food for the plant, giving it the energy it needs to grow, while oxygen is released as a byproduct into the environment. It’s important to stress that without sunlight, plants cannot create their food or oxygen. This first part of the lesson will explain how sunlight powers the kelp forest, making it a crucial component of the underwater ecosystem.
Water and Nutrients:
Water is another key ingredient for photosynthesis. Kelp absorbs water through its root-like structures called holdfasts, which anchor it to the ocean floor. The water is essential because it helps break down carbon dioxide in the photosynthesis process. Nutrients from the seabed also play a role in the growth of kelp, although they are not directly involved in photosynthesis. These nutrients help the kelp stay healthy and grow, but photosynthesis relies on water, carbon dioxide, and sunlight. This section will highlight how kelp absorbs water and nutrients from the ocean floor and how they contribute to the overall process of photosynthesis.
Oxygen Production and Ecosystem:
A byproduct of photosynthesis is oxygen, which is released into the surrounding environment. In the kelp forest, this oxygen is vital for the survival of marine life. Fish, crabs, and other sea creatures depend on the oxygen produced by kelp and other plants to breathe. As the kelp absorbs sunlight, carbon dioxide, and water, it produces glucose to feed itself and oxygen that sustains the underwater ecosystem. The oxygen bubbles rise from the plants into the water, and marine life benefits from the rich oxygen levels in these kelp forests. It’s important to convey that without this oxygen production, much of the marine life that thrives in the kelp forest wouldn’t survive. This final part of the lesson will focus on how the oxygen produced by photosynthesis supports the broader ecosystem.
Once students understand the photosynthesis process, they will move on to the engagement portion of the lesson using the Online Escape Room: "Photosynthesis Expedition: Secrets of the Kelp Kingdom." In this escape room, students will face challenges and puzzles based on the information they’ve learned, testing their understanding of how sunlight, water, and oxygen are essential to photosynthesis. Be sure to instruct the students to watch the Adventure Guide video before moving on to the escape room, as it provides all the information they will need to solve the puzzles. If any student gets stuck, remind them that there will be an Adventure Guide button on each question page, allowing them to rewatch the video for help. Additionally, if further assessment is needed, the downloadable worksheet can be distributed to test their knowledge in more detail.
This reference guide is designed to help you teach the essential components of photosynthesis in a fun and engaging way, combining direct instruction with interactive activities that reinforce key concepts. With this guide, you’ll lead your students on an exciting journey through the kelp forest, where they will unlock the secrets of photosynthesis while solving puzzles and gaining a deeper understanding of how plants sustain life on Earth.
