Here we show the photographs of the work performed by Professor of Technology, the construction of Inclinometers basic tools for data collection of angles that allow us to find heights of objects, trees, buildings, etc. remotely, without stepping on them to measure.
The Clinometer is actually a protractor. You should look through the straw the top of the object you want to measure the height, such as a tree:
then gives us an angle between the observer and the highest point of the tree. With trigonometry we can find the sine of the angle and give us the height of the tree, from the height of the observer's eyes, height must be added to determine total tree height.
Another option is to move the inclinometer until it forms an angle of 45 degrees, and the Tangent of 45 ° = 1, which means that the height of the tree is equal to the distance from the pupil to the tree, as can be taken with the tape easily. Then one must add the child's height (to the eyes).
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 Gallows of Glass, and other dependent data placement of the instrument shelter, a place to observe clouds, etc.. it requires the use of inclinometers. These data are obtained through Inclinometers accuracy and correct use.
Taking into account that the instructions had decided that students were those who built, for which it was stated that they were built with the utmost rigor and scientific and technological precision.
4.OBJETIVOS (those who want to achieve with this activity):
• Understand the importance and usefulness of the Clinometer operation to take accurate height data of trees or obstacles to the vision of clouds, remote placement of the instrument shelter, green coverage protocol, etc.
• Perform marking and cutting with precision and accuracy.
• 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):
• Clinometer. Its construction and use.
• Physical and technological performance.
• is important to study the Protocols of Vegetation Cover, Hydrology and Clouds.
6.METODOLOGÍA (how to work the contents):
• Photocopy the template Clinometer Sheet GLOBE documentation. • Cut and paste
sheets and sheets of cardboard Inclinometers the same size.
• Drill and place a metal washer into the hole. • Laminating sheets
indicated in the previous section.
• Go through the hole a piece of cotton string 15 cm long with a washer on the end.
• taped a straw to straw.
7.Place OF CONDUCT (inside or outside the school):
• Class Scope
Science and Technology • Technology Workshop.
8.RECURSOS MATERIALS (those who need or would like to use):
• Cardboard.
• Cotton Cordel.
• Steel washers.
• sherbet straws.
• Workshop Tools:
-Scissors and cutters.
-laminator.
9.Time ACTIVITY (the time available for teachers):
• A meeting of the ACT in the classroom course (50 minutes)
• Four sessions of the course ACT classroom technology workshop.
• Total Activity Time: 5 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 the use and interest to awaken in students. Because of its convenience, has decided to conduct a similar exercise with groups of 1 º ESO as a complementary activity in the teaching unit aimed at the introduction to the technology.
