Cerita tentang pemboleh
ubah
Cikgu Roy membeli dua buah basikal yang
berjenama BMX. Kemudian menjalankan
eksperimen untuk mengkaji kelajuan basikal
sekiranya saiz tayarnya berbeza.
PM : Saiz tayar PB : Kelajuan Basikal
PDM : Jenis basikal
Pemboleh ubah :
2 perkataan atau lebih…(mesti
ada parameter)
Mengenal pasti pemboleh ubah
4 cara mencari pemboleh ubah:
i. Daripada pernyataan soalan
ii. Daripada jadual
iii. Daripada graf
iv. Daripada rajah
Contoh:
1. Rajah 3.1 menunjukkan
eksperimen untuk mengkaji kesan
larutan cuka dan larutan ammonia
ke atas penggumpalan lateks.
PM : larutan cuka dan larutan
ammonia
(Jenis Larutan)
PB: penggumpalan lateks
Bahan Keadaan mentol
Rod besi Menyala
Rod sulfur Tidak menyala
Masa/ minit 0 2 4 6 8 10

Bakteria
Cakera antibiotik
berkepekatan rendah
Kawasan jernih
DIMALARKAN
DIMANIPULASIKAN BERGERAK BALAS
Saiz cakera
antibiotik
Kepekatan antibiotik
Luas Kawasan jernih
Berdasarkan situasi di atas, tentukan pemboleh ubah dan cara
mengawalnya bagi eksperimen mengkaji kadar denyutan nadi
bagi aktiviti fizikal yang berbeza.
Pemboleh ubah dimanipulasi : Jenis aktiviti fizikal
Cara mengawal: Melakukan dua jenis aktviti fizikal yang
berbeza @ Melakukan aktiviti berdiri dan berlari
Pemboleh ubah dimalarkan : Bilangan murid
Cara mengawal: Memilih seorang murid yang sama
Pemboleh ubah bergerak balas : Bilangan denyutan
nadi seminit @ Kadar denyutan nadi
Cara mengawal: Mengira bilangan denyutan nadi
seminit @ Mengira kadar denyutan nadi menggunakan jam randik
Definisi secara operasi (DSO)
 Memberi DEFINISI dengan berdasarkan
PEMERHATIAN EKSPERIMEN (PE).
Templat atau acuan
DSO
DEFINISI SECARA OPERASI (DSO)
1 2 3 4
Operasi
Apakah DSO bagi silinder berongga?
Apakah DSO bagi silinder padat?
Apakah DSO bagi kekuatan silinder?
Apakah DSO bagi aloi?
Apakah DSO bagi logam tulen?
Kedua-dua jenis paku ini direndam dalam air suling
selama 3 hari dan perubahan warna diperhatikan
pada paku tersebut.
Apakah DSO bagi aloi?
Apakah DSO bagi logam tulen?
Apakah DSO bagi inersia?
Apakah DSO bagi inersia?
Apakah DSO bagi pertumbuhan
bakteria?
Apakah DSO bagi antibiotik?
Apakah DSO bagi antibioyik berkepekatan
tinggi?
Sekian.
Terima kasih.
