Tuğba Durak Demirhan İstanbul Recaizade Ekrem İlkokulu

 Ortak sınıf dersimizde bol eğlenceli deneylerle balondan, pipetten farklı sesler çıkarmayı denedik ve sesi gördük !

In our common classroom lesson, we tried to make different sounds from
the balloon, the straw with lots of fun experiments and we saw the sound!
