Abstract
The Fisica Pato2 (Physics 4 every1) outreach group started as a need of hands-on activities and active Science demonstrations in the education for kids, teenagers and basic education teachers in Nuevo Leffon maintaining a main objective of spread the word about the importance of Optics and Photonics; for accomplish this objective, since November 2013 several outreach events are organized every year by the group. The program Optics 4 every1 is supported by the Facultad de Ciencias Fisico Matematicas of the Universidad Autonoma de Nuevo Leon and the International Society for Optics and Photonics and consist in quick hands-on activities and Optics demonstrations designed for teach basic optical phenomena related with light and its application in everyday life. During 2015, with the purpose of celebrate the International Year of Light 2015, the outreach group was involved in 13 different events and reached more than 8,000 people. The present work explains the activities done and the outcome obtained with this program.

INTRODUCTION

Currently, in correspondence with the accelerated scientific and technological development, the education not only is about how children and youth learn Science as the only outcome pursued by the process of teaching, indeed, it is clearly necessary to understand the meaning of learning Science as part of human knowledge, relate its branches not isolate them and develop the potential of all students.1 In this regard, the International Year of Light 2015 (IYL2015), provided a cross-disciplinary educational and outreach project where the program Optics 4 every 1 is supported.

1.1

Local Teaching of Science, Mexico

In the later years, the teaching of sciences has become a part of Nuevo Leon teachers interest, in consequence, Universities and local museums generated programs to fulfill this interest. A probable origin of this interest, can be, perhaps, that local teachers do not make use of experimentation to link theory and concepts and use these programs to meet this need. Moreover, the Optics 4 every1 outreach program follows the Active Learning in Optics and Photonics (ALOP) philosophy of fostering modern hands-on learning techniques2 and encourage the experimentation in schools.

1.2

Optics 4 every1 outreach program

One of the IYL2015 objectives is education and outreach, in this regard, the Optics 4 every1 is a program focused in the celebration of the IYL2015 with outreach activities to spread the word of Science and the celebration. This program was created at Facultad de Ciencias Fisico Matematicas (FCFM) and supported by the International Society for Optics and Photonics (SPIE).

The program events consisted in activities to teach certain science topics, including classical physics, geometrical and physical optics. Each event must contain at least 2 topics and relate them with hands-on experiments or demonstrations. The characteristics of the hands-on activities are: low-cost and locally-available materials and homemade. In demonstrations and hands-on activities, the time is a key factor, usually, per event, the activities must be long enough to include the topic and give significant information, but short enough to not lose the attention of the children; if the event time is extensive enough, secondary information is given and the concepts learned are explored.

1.3

Strategy development

The learning of concepts is not the only objective while learning science and, usually, this is not motivating to students, the learning of sciences must have a significant learning with favorable conditions and cognitive structure.3 Teaching must be part of students formation by including concepts, values and attitudes in a process where the student meet itself, the surroundings,4 and learn how to socialize.

As a first step of the strategy, the constructivism was used as main factor for the activities, as many authors stands, the learning is a process where the link between the experiences and ideas meet, moreover, the ideas must be linked5 to complete a knowledge of the world. In conclusion, the hands-on activities accomplish this philosophy. As a second step, the Active Learning of Optics (ALOP) philosophy was implemented on the hands-on activities,2 inspired in other successful works.5, 6 To complete the strategy, the experiences must achieve a meaningful learning as stated by David Ausubel. On the other hand, demonstrations are focused on the concepts, and usually were not inexpensive because the main objective was to demonstrate a concept and link it with the hands-on activities.

EVENT DESCRIPTIONS

The Optics 4 every1 was a 1-year program to celebrate the IYL2015, in the next years the celebration will only be in 1 day to commemorate the IYL2015. The program consisted in 13 events where students and families learned about the IYL2015 and optics. The events will be described next.

2.1

Week of light - Semana de la luz

The opening event, the week of light was on the Facultad de Ciencias Fisico Matematicas from February 19th to 23th. This event was focused on general public, mainly faculty students, with the purpose of socialize and commemorate the begging of the IYL2015 in our city. It has activities that include a Goldberg machine, see Fig. 1, where students were encouraged to socialize, use creativity and concepts to achieve a complex machine. The machine took 1 week to be constructed and the concepts applied were, mechanics, thermodynamic, pressure, magnetism with the purpose of light UV SPIE, Faculty, Universidad Autonoma de Nuevo Leon (UANL) and IYL2015 logos.

  • Khet challenge: a challenge using the Khet 2.0 laser game, this activity was used to explain the law of reflection and challenge students to complete with only pieces rotation a goal in the game (defeat the pharaoh). Teams of students socialized to achieve the goal.

  • Strobe light effects: this activity uses a strobe light, which was used to show the movement of draws on a disk, the students were asked to explain the phenomena and they relate it with the concept of frequency.

  • Moire pattern: this was used to show an optical effect of motion. This activity consists in the exploration of books with Moire patterns that show images movement. The main purpose was to contrast of strobe light effects movement, and again, a periodicity was implied.

  • Plasma ball: this activity was more complex than the others, it demonstrates the effects of the electric field on gases, its main purpose is to give an experience on what electric field can achieve, this is usually an isolated concept and the students learn it with draws about the electromagnetic phenomenon.

2.3

Visit to Elementary School Nuevo Colegio Israelita de Monterrey

This event was held on the Elementary School Nuevo Colegio Israelita de Monterrey on March 24th. This event consisted on demonstrations and hands-on activities during their cultural week. The Fig 4 show the event. The hands-on activities were:

  • Fake 3D: with a pattern in a paper, the students build a figure were they can see a cube if they use only 1 eye, this activity focus on the binocular vision and how it works.

  • Fluorescence and Phosphorescence: usually these concepts are confused, in this activity the student manipulates materials given with UV light and learn about the difference. The students also experiment with other materials they carry, like cloths, paper or pencils.

  • Tyndall effect: to demonstrate how a ray beam can be observed if it passes through smoke and relate the concept with clouds and particles in the atmosphere. In this activity the challenge is to pass through a laser maze and the students learn that at different angles, ray beams cannot be seen clearly.

2.4

Science in Family

This event was on Facultad de Ciencias Fisico Matematicas on July 11th. The activities were in support with the event Science in Family were families are gathered to learn about science. Due to diversity on ages this event includes experiments like the plasma ball, a kaleidoscope, a mirascope, a polarization kit. In the event, families come to a table full of experiments and ask how each one works as can be seen on Figure 5.

  • Kaleidoscope: this activity is to learn about the reflection, usually focused on children due to its simplicity.

  • Mirascope: this activity is to learn about the reflection on concave mirrors, the students see how an image is formed and then asked how is formed.

  • Polarization Kit: this is a complex activity about light, the polarization usually is not included in elementary school, but in this case, it was included to challenge older students. During this activity

  • Colors: in this activity the IYL2015 light blox was used.

2.5

Summer Camp Little Bisons

The summer camp Bisontitos or Little Bisons is held each year at Facultad de Ciencias Fisico Matematicas on July and is 2 weeks long. During this event, several hands-on experiments and demonstrations were shown to kids from 6 to 14 years old, due to the time of each lab class (40 minutes) the experiences in this event were huge. The activities included color, fluorescence and phosphorescence. In this event, the color activity was longer than the past events, it included the IYL2015 diffraction gratings were the students use the gratings to see different color lights and even fire as the Figure 6 shows, one interesting phenomenon is when a laser light is shown, this particular experience demonstrate the difference between light and laser light. Also, a particular activity was included, in the color activity a stereoscopic diffraction lenses were included, the objective was an experience were the students draw in a black paper and make their own 3D draws with warm colors on the bottom and cold colors on front. In addition, during the class the difference about phosphorescence, fluorescence and chemiluminescence was explained and, later, during the night closing event, the kids enjoyed a black-theater performance.

RESULTS

The activities changed along the year with the comments of students, parents and teachers, this feedback make possible the integration of teaching kits for different phenomena, also one part of the feedback was the assistant reaction: kids, youth and adults were amazed by the activities.

Looking for achieve a better understanding of the activities shown, it was necessary apply modifications with every event, public, activity and topic. The more complex activities were left to higher education levels.

With every event several questions were made by the assistants, this was also a feedback for improve our labor for future events.

In summary, thanks to the aforementioned events, more than 8,000 people were reached including not only kids, teenagers and basic education teachers, also parents and general public, who were interested in learn more about the world where we live and about the importance of the Light and its importance in our daily life.

CONCLUSIONS

These events were important to complement the local education, because the activities are ideal to link concepts with experiments. Teachers were interested on the activities and wanted to replicate in the school, but the lack of information about where to find materials like diffraction grating make it hard to replicate, this is where education kits fulfill this need.

The objectives of the International Year of Light were present in the program, and the events celebrated the IYL2015. Along the year, a lot of teachers were reached and they frequently ask for events in schools, this kind of feedback can make this program be permanent and in continuous renovation. In addition, the presentation of kits will continue to encourage teachers to experiment in class.
