• 1. LEMBARAN KERJA SISWA PENGUKURAN 1 TUJUAN : Mampu melakukan pengukuran panjang menggunakan alat ukur jangka sorong dan mikrometer sekrup Mampu melaporkan hasil pengukuran menggunakan aturan angka penting dengan baik ALAT DAN BAHAN - Mistar - Jangka sorong - Mikrometer skrup - Balok - Kelereng CARA KERJA 1. 2. 3. 4. 5. Mengukur massa benda dengan menggunakan neraca Mengukur panjang, lebar, dan tinggi balok menggunakan jangka sorong Mengukur diameter kelereng dengan menggunakan jangka sorong Mencatat hasil pengukuran Menghitung massa jenis benda dari data hasil pengukuran HASIL PENGAMATAN BALOK Pengukuran ke 1 2 3 4 5 Volume (m³) Massa (kg) Massa Jenis (kg/ m³) Σρ= Panjang (m) Lebar (m) Tinggi (m)
• 2. ρ=(.....±.......) KELERENG Pengukuran ke 1 2 3 4 5 Massa (kg) Diameter (m) Volume (m³) Massa Jenis (kg/ m³) Σρ= ρ=(.....±.......)

• 3. LEMBARAN KERJA SISWA PENGUKURAN 2 TUJUAN : Mampu melakukan pengukuran waktu menggunakan stopwatch Mampu melaporkan hasil pengukuran menggunakan aturan angka penting dengan baik ALAT DAN BAHAN - Tali 20 cm dan 40 cm - Bandul - Stopwatch - Mistar CARA KERJA 1. Gantungkan beban pada tali dan kaitkan pada statif 2. Ayunkan beban dan catatlah waktu selama beban melakukan 10 getaran 3. Catatlah hasil pengukuran HASIL PENGAMATAN Pada L = 20 cm Pengukuran ke1 2 3 4 5 t (sekon) T= t/n ΣT = T=(.....±.......)
• 4. Pada L = 40 cm Pengukuran ke1 2 3 4 5 t (sekon) T= t/n ΣT = T=(.....±.......)
