أقامت اليوم لجنة التدريب على الإخلاء بلقاء مع الأساتذة بغية التحضير لتدريب الإخلاء الكامل في ثانوية حسام الدين الحريري بغية نشر التوعية والتدريب على السلوك السليم في حال المخاطر بعيدا عن الهلع #مع_لبيئة_دامجة_و_آمنة @dina_jradi @ea_rania @Hhhsinfo

"Only a life lived for others is a life worthwhile." (Albert Einstein) Certifying HHHS learners for their remarkable participation in charitable community services. @ea_rania @Hhhsinfo @Samar_Baba1 @NadwaKaddoura @ayda_ramadan @dina_jradi

It was a fun month & a hands-on chapter with G10 students where they performed eagerly different series of experiments targeting chemical reaction objectives #labskills #commumication #analysis #thinking #stoichiometry #yield #purity @Hhhsinfo @Samar_Baba1 @dina_jradi @ea_rania

نتقدم بجزيل الشكر والتقدير لجمعية رعايه اليتيم في صيدا التي اتاحت لطلاب الحادي عشر منهج اجنبي @Hhhsinfo الفرصه بإدخال السرور على قلب أطفالها من خلال تحضير وتنظيم إفطار مميز ومتنوع في دارها. #communityservice @dina_jradi @fatimazein_az @ea_rania

Grade 12LS-GS sts worked collaboratively and accurately to perform Acid-Base Titration which reflected their communucation and self management skills. @Hhhsinfo @ea_rania

Cooking culturally Team1 did a great job while demonstrating their final outcome during CAS Global Project. #SDG #Nopoverty #Zerohunger. Well done Team👍@Hhhsinfo @HibaBayoumi @ChamandiHiba

Thank you- Mr. Anthony Rahayel-for your collaboration and valuable advices during the inspiring and emotional interview with the CAS students #cooking culturally #zerohunger #the key to success is to be passionate about what you are doing @Rahayel @Hhhsinfo @HibaBayoumi

G11 S students performing a volumetric titration experiment to determine the concentration of unknown solution #labskills #accuracy @Hhhsinfo @Samar_Baba1 @ea_rania

The greatest appreciation to @Hhhsinfo teachers & staff for accompanying the 15th promotion on their Seniors'Trip 2023; you've been so much fun, you've shown love, & you helped in creating precious memories.@dina_jradi @ea_rania

Seniors’ 23 Trip ❗️🤍 Feeling blessed beyond words for the incredible teachers and friends who have made this senior trip unforgettable. Thanks for the memories that will last a lifetime! #seniortrip @Hhhsinfo @dina_jradi @ea_rania

@Hhhsinfo Seniors' Trip 2023 has begun with breakfast and then later checking in at Country Lodge at Bsalim. Stay tuned for their updates in creating precious memories #15thPromotion

We say :" for every dark night, there's a brighter day". Hosting the Makassed Educational Day @Hhhsinfo and meeting and sharing our chemistry department strategic plan with our sisters schools is a new ray of hope in the darkness.

A fruitful webinar with @ali_ezzeddine_ @QRTAJO about the importance of teaching through concepts & the difference between 2D curricula & 3D ones in shaping future learners @dina_jradi @ea_rania @Samar_Baba1

Bac S students @Hhhsinfo performed independently a #guided_inquiry #lab_experiment by preparing a colored solution and then diluting it to observe the difference between #concentrated_solutions and #diluted_solutions @dina_jradi @ea_rania

How to prepare a solution and then dilute it? G11 S students answered this question by indepently conducting the experimental procedure from A to Z #solutions #dilution @Samar_Baba1 @ea_rania @dina_jradi

Grad 12 LS-GS sts used the gas pressure sensor to study the effect of the concentration on the chemical kinetics of a slow reaction @Hhhsinfo @ea_rania

#MEPLI at Harvard Graduate School of Education oraganized a set of mini workshops under the title "Supporting & Coaching Teachers". I was honored to attend this unique event and meet MEPLI fellows. @hgse_mepli @Hhhsinfo @ea_rania
