A large number of drain holes 14 are formed on the bottom surface. The bottom dish 2 has a triangular shallow bottom shape that is slightly larger in plan view than the planter 1.

  Each seedling cup 3 is a container having a triangular shape in plan view smaller than that of the planter 1, and the partition unit 4 can be removably inserted into the seedling cup 3. As shown in FIGS. 2 and 3, each partition unit 4 has a triangular base portion 17 that can be inserted into the seedling raising cup 3, and a partition tube 18 is erected on the base portion 17. The partition cylinder 18 has partition walls 19 that stand vertically corresponding to the respective corners of the base portion 17, and regions that are outside the partition walls 19 and inside the corners of the base portion 17 are respectively provided. It is a space for a triangle nursery. A knob 20 is provided on the upper surface of the partition tube 18. Reference numeral 21 denotes a partitioning projection that also serves as a reinforcing material protruding from the side surface of the partitioning wall 19.

As shown in FIG. 4, the corner cover 10 is vertically long and is formed in a columnar shape having a substantially triangular shape in plan view. FIG. 5 shows a cross-sectional view along the line AA and a cross-sectional view along the line BB in FIG. 4. As shown in these cross-sectional views, a protective bowl is manufactured on one side of the corner cover 10. There are provided two fitting parts 23 capable of fitting the end of a piece of wood (8a) obtained by cutting the wood piece 8 for use, the orientation of the opening of one fitting part 23 and the other fitting The opening direction of the joint portion 23 intersects with each other at an angle of 60 degrees.
The planter 1, the bottom plate 2, the seedling cup 3, the partition unit 4 and the corner cover 10 are each integrally formed of a synthetic resin material such as polypropylene.

  Next, the procedure for advancing classes using this teaching material kit will be described.

  First, a teaching material kit is provided to each child. As shown in FIG. 6, each child opens the tablet-shaped culture soil 7 in the bag on the bottom dish 2 and injects water into the culture soil 7. The seedling cup 3 is used as a lightweight cup for water injection. By using the seedling cup 3 as a lightweight cup, a predetermined amount of water can be appropriately injected into the culture soil 7. After the water injection, loosen the culture soil 7 while spreading it in the bottom dish 2.

  Next, as shown in FIG. 7, the partition unit 4 is inserted into each seedling cup 3. A triangle surrounded by each partition wall 19 and each corner wall of the seedling cup 3 between each partition wall 19 of the partition unit 4 and each top wall of the seedling cup 3 by inserting the partition unit 4. Spaces for shaped nurseries are created, and these spaces become nursery areas. Three such seedling areas are formed for each seedling cup 3.

  Next, the culture soil 7 in the bottom plate 2 is uniformly packed in the spaces inside the seedling cups 3. As a result, three nurseries are made in each nursery cup 3. After this, plant seeds one by one on each nursery and wait for germination. In this process stage, children can learn experientially how to treat the culture soil 7, how to make a nursery, how to sow seeds, and so on.

  Next, after this work or in parallel with this work, as shown in FIG. 8, the planter 1 is placed on the bottom plate 2, and the cultivation soil 5 in the bag is put into the planter 1, Mix organic fertilizer 6 and prepare for seedling planting. At this stage, each child can learn about organic farming.

  The seedling cup 3 of each seeded child is installed in a required place such as in a classroom and waits for germination while taking care of watering. Each seedling cup 3 has a triangular shape. Therefore, a large number of seedling cups 3 can be arranged closely adjacent to each other without creating a useless space. Therefore, even in a narrow place such as a classroom window, it is possible to densely and efficiently install the nursery cup 3 for each child.

  The seeds sown in the nursery cup of each seedling cup 3 will germinate before long, so the child observes the growth of the buds. Each nursery cup 3 is formed with three nurseries, seeds are sown in each nursery bed, and the seeds germinate, so that it is possible to observe while comparing the degree of bud growth in each nursery bed. . Through such observations, you can experience how the buds grow and how they grow.

  While waiting for the growth from germination to seedlings, make a protective pot. In this production, first, the long wood piece 8 of the wood pieces 8 and 9 prepared in advance is cut so that the child divides the longitudinal direction into three equal parts using a saw, as shown in FIG. Thus, three bowl side plates 8a are obtained. Then, the three side plates 8a are arranged in a triangular shape, and as shown in FIG. 10, straddling the end of one side plate 8a adjacent to each other and the end of the other side plate 8a as the corners of the triangle, Two corner covers 10 are fitted. That is, the end portion of one side plate 8a is fitted into one fitting portion 23 inside the corner cover 10, and the end portion of the other side plate 8a is fitted into the other fitting portion 23 inside the corner cover 10 ( (See the chain line in FIGS. 4 and 5). Then, the corner cover 10 is fixed to both side plates 8a with screws. This operation is similarly performed on the other two corners of the side plate 8a arranged in a triangular shape, and the side plates 8a are fixed to each other to assemble a triangular frame as shown in FIG. .

  After that, as shown in FIG. 11, a short-sized piece of wood 9 is cut into a required shape with a saw to form a bottom plate 9a, and a bottom plate 9a is assembled into a triangular shape using a hammer on the bottom surface of the frame. Strike. Thereby, the protective bowl 30 is completed.

  In this work process, children can learn woodworking, that is, how to use a saw, how to cut a piece of wood, how to use a hammer, how to handle nails and screws, how to assemble woodwork. When assembling the triangular protective bowl 30, it is only necessary to fit the side plates 8a adjacent to each other to the corner cover 10 and fix them. Therefore, even an unskilled child can assemble the corners at an appropriate angle. Can do.

  When the sprout germinated in the seedling cup 3 grows into a seedling, the seedling is transplanted. At the time of this transplantation, as shown in FIG. 12, first, the partition unit 4 is pulled out from the seedling cup 3 and taken out. The partition unit 4 can be easily lifted by pinching the knob 20 with a fingertip. In one seedling cup 3, seedling beds are made in three seedling areas, but the three seedling beds are supported by the base portion 17 of the partition unit 4, and therefore, by lifting the partition unit 4 and taking it out, The three nurseries can be extracted from the nursery cup 3 at the same time. And since the whole seedbed is extracted integrally with the partition unit 4, the seedbed and seedling roots are not damaged or the roots are not broken.

  Since there are two nursery cups 3, the nursery beds are extracted from the two nursery cups 3, respectively. Therefore, there are six nurseries. Then, for each of the seed beds, the growing state and the rooted state of the seedlings are observed, the seedling having the best growing state is selected from among them, and the soil for cultivation in the planter 1 in which the selected seedling has already been prepared. Transplant to 5. Through this process, it is possible to learn how to grow seedlings, observe the rooted state and transplant seedlings.

  After transplanting the seedlings to the planter 1, the planter 1 is stored together with the bottom plate 2 in the protective pot 30, as shown in FIGS. 13 and 14. Then, a protective bowl 30 for each child is installed in a required place such as a classroom or school yard, and the growth of seedlings is observed while taking care of watering.

  When the planter 1 for cultivation becomes dirty, the planter 1 for cultivation is taken out from the protective pot 30 and cleaned. The triangular planter 1 has a flat corner 13 that does not protrude sharply at one of its corners. For this reason, between the corner 13 and the protective pot 30 of the planter 1 for cultivation. There is a certain space. Therefore, the planter 1 can be easily taken out by inserting a finger into the space and placing the fingertip on the planter 1 for cultivation.

  The protective pot 30 in which the planter 1 is housed has a triangular shape. Therefore, a large number of protective pots 30 can be closely adjacent to each other to form a flower bed without creating a useless space. For example, as shown in FIG. 15A, six protective pots 30 divided into groups are arranged in a horizontal row so that one side surface of each group is adjacent to each other to form a horizontal flower bed, or as shown in FIG. 15B. In addition, the six protective pots 30 can be arranged in a hexagonal shape so that one side surface is adjacent to each other to form a square flower bed. Furthermore, it is possible to use a flower bed of various shapes such as a star shape and a triangle.

  In this way, by using the teaching material kit of the present invention, it is possible to make the teaching about biological training and the teaching about woodworking work effective in parallel and with interest to the students, thereby improving the efficiency of the lesson. Can be achieved.
