How To Help Itchy Hyives

CONSTRUCTION densiometer

majos See what the students of 2 º ESO parcel bounded by training the Study of Vegetation Cover Protocol and the use of constructed densiometer:



also some photographs of densiometer built by students of 4 º ESO Diversification:



The densiometer used to record the presence or absence of vegetation in the vertical pupil, both up and down, recording also the type of tree, shrub, etc.



1.ORGANIZACIÓN (departments, tutors or teachers responsible, contributing):
Ana Isabel Fernández González. Professor of Technology and the Scientific-Technological Area 4 º ESO Diversification.

2.DESTINATARIOS (Courses and number of students): 4 º ESO
Diversification (10 students).

3.JUSTIFICACIÓN (how comes the need for this activity):
The need to introduce in the GLOBE server Vegetation Cover data from our study area in Glass Gallows requires densiometer building, building which has the instructions. These data are obtained through proper use of densiometer constructed, for which they must be built with the utmost rigor and precision of science and technology.

4.OBJETIVOS (those who want to achieve with this activity):
• Understand the importance and usefulness of densiometer operation to take accurate data.
• Perform cutting, drilling and marking with rigor and precision.
• Follow guidelines of teamwork and participation.
• Work in the classroom workshop following the rules of hygiene and adequate security.

5.CONTENIDOS (major content to work or strengthen):
• Tubular densiometer. Its construction and use.
• Physical and technological performance.
• is important for the study of vegetation.

6.METODOLOGÍA (How to work the contents):
• Performing densiometer sketch to scale to be built.
• Organizing tools and materials needed for the realization of densiometer.
• Monitoring of measuring and marking operations.
• Perform cutting, drilling and placement of the cords in the tubular structure.

7.Place OF CONDUCT (inside or outside the school):
• Classroom Field Reference Science and Technology.
• Technology Workshop.

8.RECURSOS MATERIALS (those who need or want use):
• Cardboard tubes of 6 cm outside diameter.
• Cotton Cordel.
• Steel washers.
• Workshop Tools:
-Drill and Auger.
-cutters and Hacksaw.
-Rule square and pencil.

9.Time ACTIVITY (the time available for teachers):
• A meeting of the ACT in the classroom course (50 minutes)
• Two sessions of the course ACT Technology Workshop. (100 minutes)
• Total Activity Time: 3 sessions of ACT.

10.PREVISIÓN TRANSPORT:
not need transportation.

ECONOMIC 11.PRESUPUESTO :
Cotton Cordel: 5 €
Steel Washers: 4 €.

12.CUALQUIER OTHER RELEVANT INFORMATION:
GLOBE was an experimental activity, in relation to awaken interest in students.
Because of its convenience, it was decided to perform the same activity with groups of 1 º ESO as a complementary activity in the teaching unit aimed at the introduction to the technology.
has also been decided that all students build their own home densiometer materials (cardboard tube from toilet paper rolls, wire, nuts, etc.).. It's that could use in the field trip to the Rock Muñana for taking land cover data.
also going to try to build more precise densiometer PVC pipes.
