At first, students have been informed about hologram. After students have formed their groups (3 or 4 students), each group has drawn 4 trapezoids that had different sizes. Afterwards, trapezoids have been get together.

Then the formed shape have been put on a hologram video. Students have been impressed by 3D vision of hologram. They have realized different sizes (ratios) of acetate papers provide different visions. Hologram videos on tablet or grater screens requires different sizes of the best ratio.

Finally, we have talked about purposes of hologram usage.

The beginning was a distinctive activity that helped students realize its importance in daily life, and they were able to prepare the holographic hologram according to the required measurements, and from the original measurements the second ratio was calculated, then a larger and smaller scale was calculated based on it and compared to what appeared, the activity taught them to mix mathematics, technology and art, so the learning process is integrated .

Hologram var olan herhangi bir nesnenin lazer ile gösterilmesine denir.Hologramın kullanım alanı fazladır.Hologram ışığın yansıtılarak görüntünün tabaka şeklinde görülmesini sağlar. Aynı zamanda iki tane farklı lazer ışınlarının birleşmesi ile üç boyutlu bir fotoğraf elde edilir. Bu hologram sayesinde yapılmaktadır.Hologramın kullanım alanı çok fazla bir teknolojidir. Son yıllarda sıklıkla tercih edilen bir teknolojidir.

Şehit Cemal Demir AİHL okulu 6-A sınıfındaki öğrencilerim ile basit hologram yapımı için online derste buluştuk.İki farklı ölçülerde oranlama yaparak görüntüyü kıyasladık. Matematiğin günlük hayatta karşımıza heryerde çıkabileceğine dikkat çektik. 1. etkinliğimiz olan HOLOGRAM yapımını keyifli bir şekilde tamamladık.

A hologram is a laser to show any existing object. The hologram has a lot of usage area.The hologram allows the image to be seen as a layer by reflecting the light. At the same time, a three-dimensional photograph is obtained by combining two different laser beams. This is done thanks to the hologram.Hologram has a lot of usage area. It is a frequently preferred technology in recent years.

We met with my students in class 6-A of  Şehit Cemal Demir AİHL school in an online lesson for simple hologram production.We compared the image by proportioning in two different sizes. We drew attention to the fact that mathematics can appear everywhere in daily life. We completed the construction of HOLOGRAM, which is our first activity, in a pleasant way.

First of all, we ask our students “What is a hologram?” and information was given in which areas the hologram is used.

The necessary materials for the hologram activity were announced to the students. An online meeting was planned to do the hologram activity with the students together. By holding online meetings with students, holograms of different sizes were made together at the same time.

Students opened hologram videos from their phones and tablets and placed them on the holograms we created, and wonderful images came out.

The students were very impressed by the 3D images and had fun.

We decided to meet with the students at our school and prepare the board of our project and show our hologram activity to other students and teachers.

We met at our school and prepared our board explaining the introduction of our Project and our activities. And we did a visual show for our other students and teachers.

With this activity, the students saw that the subject of ratio in mathematics is used in our daily life, technology and science. They got to know the hologram technology better.

Materials used:

(marker, pen, cutter, transparent plastic, ruler, chopping board, tape, paper)

Steps:

1. We start making a template on paper

Draw line 6 cm

Draw line 3.5 cm in the center of the last line and with a 90-degree angle

Draw line 1 cm Parallel with the first line

Link the top and bottom lines ( parallel lines)

2. Cut out the template

3. Put the template on the transparent board with tape

4. Pull it over with the marker 4 times

5. Cut out the shapes

6. Paste the shapes together

7. Search “ Hologram video “ on YouTube

8. Put the pyramid on your phone

First activity: 1. Aktivite (Oran- Hologram)
Güneş sisteminde:
1.Gezegenlerin çapları Dünya'nın çapı ile oranlandı böylelikle büyüklükleri karşılaştırıldı.
2.Gezegenlerin Güneşe olan uzaklıkları Dünya'nınki ile oranlandı Astronomik Uzaklıkları hesaplandı.
3.Gerçeğe yakın veriler üç boyutlu maketlerle desteklendi.
4.Wordwall programıyla Güneş Sistemi gezegenlerigörsellerle pekiştirildi.
5.Hologram zeminleri 1,5 x 5,5 x9cm lik yamuklarla oluşturulan geometrik şekillerle ve oranlarıyla ölçeklerin 2 katıyla hazırlandı.
6.Hologram programlarında Güneş Sistemi oluşturuldu.

Firstly, what hologram is in real life was taught to students. Some examples related to hologram were shown. Then, it was said that we would design holograms with different sizes (the same rates) in this lesson. One size of hologram was given in order to make it. After then, it was wanted that they would make bigger and smaller holograms in the same rate.

Students designed their own holograms in distance learning. After one day, they showed and introduced their own holograms to the other students in our school (Halilurrahman Middle School). The other students watched their holograms admiringly.

Students who make holograms in Halilurrahman Mıddle School taught how ratio which is one of math topics uses in this lesson because it is necessary in order to acquire the same view. Moreover, hologram is one of the most important inventions in these days. Therefore, students know hologram and what it does now.

Proje öğrencilerimizle okulda buluştuk ve projemizin panosunu oluşturmak için öğrencilerimiz afişlerinin ve ilk etkinliğimiz olan hologram kolajlarının çıktısını panomuza astılar. Ayrıca hologramlarını da getirerek okuluzdaki diğer öğrenci ve öğretmenlerine hologram görüntüsü sundular.
