Memahami Konsep "Benda di Sekitarku" dan Sifatnya

Sebelum masuk ke dalam contoh soal, mari kita segarkan kembali pemahaman tentang materi yang akan diujikan. Tema 3 "Benda di Sekitarku" secara umum mengajak siswa untuk mengenali dan memahami berbagai benda yang ada di lingkungan terdekat mereka. Lingkungan ini bisa berupa rumah, sekolah, taman, atau bahkan kelas itu sendiri. Siswa diajak untuk mengamati, mengidentifikasi, dan mengelompokkan benda-benda tersebut berdasarkan ciri-cirinya.

Subtema 1 "Benda Keras dan Benda Lunak" berfokus pada salah satu karakteristik fisik benda, yaitu kekerasan. Siswa akan belajar membedakan antara benda yang memiliki sifat keras, yang sulit untuk diubah bentuknya atau ditekan, dengan benda yang memiliki sifat lunak, yang mudah diubah bentuknya atau ditekan. Pemahaman ini penting karena akan menjadi dasar untuk mempelajari sifat-sifat benda lainnya di subtema berikutnya, seperti benda padat, cair, dan gas, serta sifat-sifat seperti kelenturan, kelicinan, dan kekasaran.
