Hands-on Photosynthesis Ideas?

    Posted 03-27-2024 10:07:00 PM

    Hi there everyone and Happy Spring from Virginia! 

    I had a request from the 5th grade teachers at our school to come into their classrooms and do a mini (15 min), hands-on lesson on photosynthesis because the students don't seem to be retaining the information. I can understand why, as it's quite the process to explain! I'm wondering if anyone here might have a fun way to help reinforce this concept? I'm struggling to find a way to make this fun and hands-on for the kiddos. I also feel added pressure whenever I'm invited into classrooms to make the lessons extra engaging because these teachers don't see me in action in the garden and I want them to take more of an interest in what my program does!

    Thanks so much! 

    Alicia

    I've used this activity and this short video shows how to do it.  https://www.youtube.com/shorts/oHDTWLPyKN0

    Hi Alicia,
    I find that showing a short video helps. Many kids are visual learners.
    You can find some good ones on line that are done very well and are age appropriate. Continue the lesson in the garden while looking at plants.

    Thanks Peggy! I will search for good videos for sure. It's a nice starting point.

    I would like some help with this.  I tried following the video that uses the spinach cut from a hole puncher and put the cut-outs in a glass with baking soda.  But my spinach never sank, not even when I covered the glass with a towel so no light could reach it.  I want to do this experiment with a group of kindergarten children and it sounded like something that could be done in a short period of time.  But as I said, it did not work.  Can anyone shed some light (no pun intended!) on what I am doing wrong?  Thanks so much!

    Make sure the lights are off when you start and then use a lamp or flashlight under the glass and see if that helps. How much baking soda are you using?  Here is another link that shows more details.  https://www.google.com/search?q=experiment+showing+photosynthesis&rlz=1C1GCFZ_enUS1067US1067&oq=experiment+showing+photosys&gs_lcrp=EgZjaHJvbWUqCAgBEAAYFhgeMgYIABBFGDkyCAgBEAAYFhgeMg0IAhAAGIYDGIAEGIoFMg0IAxAAGIYDGIAEGIoFMg0IBBAAGIYDGIAEGIoF0gEINzY3NmowajeoAgCwAgA&sourceid=chrome&ie=UTF-8#fpstate=ive&vld=cid:c4772621,vid:gCHW7f88bAc,st:20

    Here's an idea:

    Photosynthesis Lesson - Air and Plants  (adapted from Project Learning Tree)

    Fill a bowl with fresh water.

    Mix baking soda into the water to provide carbon dioxide to the plant.

    Place an aquatic plant inside a drinking glass.

    Lower the glass sideways into the bolw of water until the glass fills with water and no air bubbles are left in the glass. Then turn glass upside down without letting in air. The glass should rest on the bottom of the bowl. Aim light from a lamp toward the plant on the side of the glass.

    You will see small bubbles forming on the leaves in the water. Most bubbles will come from the side of the plant nearest the light. After about an hour, you will see that a large bubble will form on the top of the water inside the glass. This bubble contains the oxyen that the plant has made.

    If you are outside, just put a plastic bag over a large leaf on a plant or a tree. It will take only a few minutes to start sweating.

    Thank you Evelyn! This is a great experiment to do with the kids.

    here's what chat gpt gave me:

    Activity Title: "Plant Power: Photosynthesis Explained"

    Objective: To help students understand the process of photosynthesis and the role of plants in producing oxygen.

    Materials Needed:

    1. Small potted plants (one per group of students)
    2. Sunlight or a bright light source (e.g., lamps)
    3. Water
    4. Cups or small containers for water
    5. Colored construction paper (green, red, blue)
    6. Scissors
    7. Glue or tape
    8. Markers or colored pencils

    Activity Steps:

    1. Introduction (5 minutes):

      • Begin by asking students what they know about plants and how plants make their own food.
      • Introduce the concept of photosynthesis as the process by which plants use sunlight, water, and carbon dioxide to produce oxygen and glucose.
    2. Photosynthesis Demonstration (5 minutes):

      • Gather students around a small potted plant placed in direct sunlight or under a lamp.
      • Explain that plants need sunlight for photosynthesis and demonstrate how sunlight helps the plant grow and produce oxygen.
      • Use this opportunity to discuss the importance of plants in our environment and how they help produce the oxygen we breathe.
    3. Hands-On Activity (10 minutes):

      • Divide students into small groups and provide each group with a potted plant, a cup of water, colored construction paper (green, red, blue), scissors, glue or tape, and markers.
      • Instruct students to create a "photosynthesis diagram" using the materials provided. They can use the green paper for leaves, red paper for flowers, blue paper for water, and markers to label the parts of the plant and the process of photosynthesis.
      • Encourage creativity and accuracy in their diagrams, emphasizing the key elements of sunlight, water, carbon dioxide, oxygen, and glucose in photosynthesis.
      • Circulate among the groups to provide guidance and answer any questions.
    4. Wrap-Up (2 minutes):

      • Have each group present their photosynthesis diagrams to the class, explaining the process step by step.
      • Summarize the key points of photosynthesis and its importance in the ecosystem.
      • Ask students to reflect on what they learned and how photosynthesis connects to their daily lives.

    Extension Ideas:

    • Have students conduct a simple experiment to observe the effect of sunlight on plant growth.
    • Explore the role of chlorophyll in photosynthesis through a mini-science experiment using spinach leaves and acetone.

    This activity combines hands-on learning with visual representation, allowing students to actively engage with the concept of photosynthesis and gain a deeper understanding of how plants contribute to our environment.

    Thanks Alycia! I need to spend some time figuring out chat gpt. It always amazes me!

    I am going to do the following experiment with fourth graders for the first time this month and can let you know how it goes, but the teachers are giving me two 30 minute sessions in the classroom, so it takes a lot more time than you're allotted. But it sounds memorable, and knowledge retention is what I'm going for since I had the same request from teachers at one of my schools as you had.
