Solar System
Solar system is a collection of celestial bodies composed of a star called the Sun and all the objects that are bound by its gravity. The objects including eight known planets with elliptical orbits, five dwarf planets, 173 natural satellites that have been identified, and the millions of heavenly bodies (meteors, asteroids, comets). Solar System is divided into the Sun, the four inner planets, the asteroid belt, four outer planets, and in the outer part is the Kuiper belt and disc Greatest.
PENGUKURAN
Pengukuran merupakan kegiatan membandingkan suatu besaran yang diukur dengan alat ukur yang digunakan sebagai satuan.Beberapa aspek pengukuran yang harus diperhatikan yaitu ketepatan (akurasi), kalibrasi alat, ketelitian (presisi), dan kepekaan (sensitivitas). Dengan aspek-aspek pengukuran tersebut diharapkan mendapatkan hasil pengukuran yang akurat dan benar.
Fotosintesis
Fotosintesis adalah suatu proses biokimia yang dilakukan tumbuhan untuk memproduksi energi terpakai (nutrisi) dengan memanfaatkan energi cahaya.Fotosintesis dikenal sebagai suatu proses sintesis makanan yang dimiliki oleh tumbuhan hijau dan beberapa mikroorganisme fotosintetik.Sumber energi cahaya alami adalah matahari yang memiliki spektrum cahaya infra merah (tidak kelihatan), merah, jingga, kuning, hijau, biru, nila, ungu dan ultra ungu (tidak kelihatan).

Berkembang biak atau reproduksi adalah kemampuan makhluk hidup untuk memperoleh keturunan. Perkembangbiakan ini berguna untuk melestarikan jenisnya.Cara perkembangbiakan pada hewan dibagi menjadi dua macam, yaitu secara generatif (kawin) dan secara vegetatif (tak kawin). Pada hewan tingkat tinggi umumnya berkembang biak secara kawin, sedangkan pada hewan tingkat rendah berkembang biak dengan vegetatif (tak kawin).Pada tumbuhan, mereka tidak hanya berkembang biak dengan biji, tetapi juga dapat berkembang biak secara vegetatif atau tidak kawin. Contoh perkembangbiakan vegetatif pada tumbuhan, di antaranya stek, cangkok, dan tunas.
