Alat :

Bahan :1. Mikroskop

1. Air rendaman jerami/air sawah/air kolam2. Kaca objek3. Kaca penutup4. Pipet tetes

5. Gelas kimia II. Cara Kerja1. Letakkan 4-5 kapas di atas kaca objek sebelum meneteskan air sample unutk menghambat gerakan beberapa protista yand dapat bergerak dengan cepat.2. Teteskan air sample,sebanyak 1-2 tetes di atas kaca objek. Lalu tutup dengan kaca penutup.3. Amati dengan dengan menggunakan mikroskop ,gunakan perbesaran 100-400.4.
