Abstract
A greenhouse is a structure that produces a microclimate ideal for plant growth. It can be used to grow plants or to care them throughout their life. Greenhouses protect crops from too much heat or cold and shield their inhabitants from storms and harsh weather. In other words, it helps to control temperature, humidity and luminosity, three very important factors in the development of plants. They also help keep out damaging pests.
Undoubtedly, in-home greenhouses are the best way of ensuring the quality of fruits and vegetables. In addition, when creating a greenhouse from recycled or reused materials environmental impact is reduced.
With this activity learners will not only learn how to make a small homemade greenhouse and how to provide plants with the perfect atmosphere for their growth but they will also become aware of the importance of reusing objects, of reducing plastic consumption and of responsible consumption. This activity can be developed individually by learners or as a group activity, and its objective is to teach learners how to create a small in-home greenhouse, and to raise awareness on self-consumption and reduction of the environmental impact.
Learning Outcomes
The learners will learn about science, agronomy and environmental impact and, concretely, about how to plant seeds in a greenhouse created from recycled materials and how greenhouses work.
- Extend understanding on how greenhouses function and how seeds can be landed.
- Recall environmental consciousness.
- How to organize group-work.
- How to build a small greenhouse.
- Develop scientific skills.
- Develop creativity.
- Manage time and resources (for achieving objectives)
- Improve social skills such as leadership, organizational conscience, and communication.
Other Instructions
- Prepare the cases: clean them if necessary.
- Building up the walls: use 4 CDs for the end walls and 6 for the sidewalls. It is important that you place each CD in the correct position before gluing them, therefore, select the pattern of the CDs in a surface such as table.
- Glue the centre CD to the wall’s peak: make sure that it is well centred, so, if it necessary use a ruler.
- Getting the angles accurate: start by the right corner of the peak by placing a whole case in the empty space (hinge facing the left and the open space facing down). Lay a ruler across the case so that the edges line up with the corner of the full cases next to it and below it. Use your craft knife to score a line across the case that’s going to be cut.
Once the case is marked, score a new line on the other of the case, exactly matching the other line. Now that both sides are marked with a line, open the case up so it lays flat and score matching lines on the inside.
Cut over all the lines on the front, back, inside, and outside of the case. You’ll notice that the two pieces don’t hold together very well, so fix this take a leftover part of the case and cut a piece off the edge. Then, glue the edges of the case together and the leftover edge piece in between the front and back of the case to support the top.
- Glue the edges of the walls, holding them in place with tape until the adhesive dries.
- To make the top of the roof four cd’s are bent in half and lined up to form a peak. In order for the roof to lay flat against the end walls the plastic edge on the short side of the case (the part that’s opposite the hinge) needs to be cut off.
- Finishing The Roof With Folding Panels: You’ll need four cases for each side of the roof. Open the cases so they are lying flat, and glue the edges together to make a panel. Place the panels so they overlap the roof’s peak. Be sure the flaps fold up or else you won’t have panels that open for watering and ventilation. Use tape to hold the panels in place until the glue dries.
