Week 3
Practical part
Transplanting plants and launching a hydroponic system
Step 1. Carefully remove the plants with soil from the dishes. Then remove the soil. Leave only plants with roots. Rinse the roots with running water.
Step 2. Wrap the roots with foam.
Step 3. Immerse the plant with foam into the bottle. So that the roots can feed on water.
Step 4. Prepare the nutrient solution. Pour water into the container and add the nutrient solution according to the instructions
Step 5. Check the hydrogen index of the water
Step 6. Turn on the pump, monitor the system.
Congratulations, your hydroponics is ready!!!
Presentation discussion of projects
This week, students should present their finished project on the following points:
1. Scientific research on the topic: Hydroponics vs traditional method
– ready-made presentation made on whatman or in other applications of your choice;
– discussion by the whole class.
2. Hydroponic system
– by presenting and showing the model, the group demonstrates knowledge in the field of natural science, namely in engineering;
– demonstrate the hydroponic system.
3. Laboratory tests:
– explain the principle and action of the nutrient solution;
– analyze the quality of water.
Evaluation
PBL evaluation criteria:
Project based learning (project-based learning) is a learning method in which students acquire knowledge and skills by working on one project for 3 or 4 weeks to research and find an answer to a genuine, interesting and complex question, problem or challenge (follow the link below PBL Rubrics ).
