"what do you want to talk about?" asked Amora who was sitting on the sofa opposite Bram and Sisil
the atmosphere there is quiet, there is only Bram, Sisil, Granny Rossa, Amora and Tamara while Dusk and Mentari are invited out to the park by the Jesi bik, then Ezra had not come yet, Bram had to talk to the five people
"hurry Bram I want to go to the room" said Rossa's grandmother impatiently want to go to bed
"patience is ma'am.. yes this Bram talk so this is another week Twilight tenth birthday dad want us to make an event for him but that makes dad confused we want to be there where the event is?"
"do you want to see what the show is like?" ask Tamara
"his father wants to invite his school friends to the Twilight school so he is happy to have his friends at his birthday" replied Bram
"we already have it in the park, continue to ngundang both friends so they can freely play" said Amora
"but there's something that makes me afraid of Ra, I'm afraid when the Dusk anniversary event takes place there's more terror"
"Bram. don't worry about these intruders only terrorizing if we're in a closed room, if we are in the outside environment he has trouble to terrorize because there will be many people who make him distress, mother will prepare people to secure the venue later" rossa said she knew Bram was worried
"are you sure?"
"hmm I'm sure"
"alright then, Amora you and others take care of the decoration" said Bram

"iyaa Amora says it's with the other friends" Amora replied

the day that Tamara was waiting for was where today she was going to take the science race
KSN or National Science Competence, now known as the National Science Olympiad (OSN), is an annual science competition for SD, Junior High School, and Elementary School students, and SMA and its equivalent throughout Indonesia. The competition was organized by the National Achievement Center under the Ministry of Education, Culture, Research, and Technology of the Republic of Indonesia (Kemdikbudristek, formerly Kemdikbud). Students who participate in this competition are the best students from their respective provinces who have passed the district and provincial selection. The competition is held in a different city each year.
OSN is expected to deliver students to master science and technology, and, this competition is also an important part in the equitable distribution of achievements and maximizing the potential of talented and character learners from all corners of the Unitary State of the Republic of Indonesia. In addition to being a strategy to improve the quality of education, science competitions have held special positions at various prestigious events in the international world in the mastery of science by students. Thus, through this systematic and tiered competition system is expected to build the widest space for learners to explore abilities in the field of science and reach the peak of their best potential. Maximum achievement will be demonstrated by the birth of qualified and highly competitive science competition champions who are ready to compete at the international level.
The results of the OSN are also a consideration in the selection process of learners who will be prepared to represent Indonesia at the international science olympiad events.
"huuhhhfff" Tamara exhales to reduce the nervousness in her, Davin pats Tamara's shoulder trying to strengthen the girl
"can" said Davin smiling "itagaaaa sweetness.only this time brother Davin smile very sweet" inner Tamara looked at the man.
"thank you brother already want to teach Ara, already want to be Ara's teacher, already want to spare time to continue to teach and for his knowledge, I will try to win" said Tamara smiling looking at Davin
Davin ruffled Tamara's hair and chuckled "that dong should win, cape gua ajarin lo if you know you lose here" Davin joked as a result Tamara followed her stomach
"ohh already good at martial arts apparently" muttered Davin
"he was taught by Mora's sister" Tamara replied
"Good morning to the faithful spectators.Good morning to the participants of the race, prepare yourself to go up here let's welcome the first participants of the race" MC opened the event by calling the first participant
a male student entered wearing a white suit in front of him already had a table he would use to experiment with, the judges watching the boy
inscribed on the monitor screen behind her experimental concept is RAINBOW IN A GLASS
he began to dissolve the sugar with different colors and then he poured and piled this sugar water slowly
the colored sugar water will not merge and fuse into one because they have different density
the judges could see there was a rainbow in the glass and they nodded their heads and began to assess the results of the experiment, Tamara was getting nervous when she saw the experiment results that the student was so perfect there was no obstacle in making the rainbow, he glanced at Davin who was already sitting on his stool the man looked towards him and excited him
"hufftt okay Ra lo can, show that you can definitely not be disappointed everyone" his monologue encouraged himself
"nice.. give a standing ovation.really we have a child who has talent and intelligence, surely his future is as beautiful as the rainbow that he made well we to the next participant.. "
as time went on, many participants showed their experimental results, but some failed until they had to stop, now it was Tamara's name to be called forward, his heart was pounding all eyes were set in his direction he could see the eyes of Sisil who just kept looking at him while both hands were linked on the chest as if praying
Tamara stood in front of him just as the other participants wore white coats complete with gloves
"please start" said MC
"thank you, well my concept here is to BLAME THE CLOCK WITH LEMON POWER
Maybe we're here asking how the flow of electricity can happen? how can a lamp be brightly lit?
In addition to the source of electricity in general, in fact we can make electric current with everyday materials. Of course with a voltage that is not too high." Tamara began to explain while showing the material she used to the audience and also the jury, Tamara's action was different from the other participants she could explain while experimenting it made the jury interested
"light the clock with lemon energy. This concept is electrochemistry. Lemons have an electrolyte solution so that electrons can move from a positively charged substance (cathode) to a negatively charged substance (anode). Electron movement begins when the zinc layer on one of the galvanized nails used begins to lose one electron per zinc atom. The zinc becomes positively charged, and electrons move through the lemon to the copper wire.
When we add a clock and close the circuit, electrons move through both the lemon and the clock, thus moving or turning the clock on. For a larger current, you can use more lemons or replace them with potatoes and so "Tamara shows her clock experiments to both the jiri and the audience.
the judges got up from their seats and clapped their hands followed by the audience behind, Tamara covered her mouth in disbelief as many clapped her hands she saw Davin who was also standing while giving a thumbs up to her
