Hypothesis : Bacteria thrives in neutral conditions / neutral condition is suitable for the growth of microorganisms
Variables : Constant variable : Volume of nutrient broth Manipulated variable : pH value Responding variable : Cloudiness of the nutrient broth
Materials/ : Sterile nutrient broth, bacteria culture (Bacillus subtilus), distilled water,apparatus hydrochloric acid 1 mol/dm , sodium hydroxide solution 1 mol/dm3 ,
test tubes,cotton wool.
Procedure 1. Three test tubes labeled A,B and C are prepared.2. 5 cm3 of nutrient broth is poured into each test tubes3. 1 cm3 of bacteria culture is added into each test tubes.4. 1cm3 of hydrochloric acid, 1cm3 of sodium hydroxide solution and
1cm3 of distilled water are added by using syringes into the nutrient broth in test tubes A ,B and C respectively.

SAMPLE EVIDENCE 10
Topic : Inertia
Aim To investigate the relationship between mass and inertia.
Hypothesis The larger the mass of an object ,the greater the inertia of the object.

PEKA SAINS SPM 1511/3
(a) Manipulated The mass of sphere(b) Responding The distance of the sphere’s movement(c) Constant The angle of inclination , the length of thread,
the mass of pendulum
Material/Apparatus Thread, mass of spheres of 50g, 100g,150g , retort stand , pendulum and metre rule.
Procedure
1. The apparatus is set up as shown in the diagram above. 2. The pendulum with 50g weight is tied to the retort stand with a 50cm length of thread.3. The pendulum is displaced at an angle of inclination of 30º
from the perpendicular and released to knock the 50g sphere on the table.
4. The distance of the sphere’s movement is measured with a metre rule.5. The result is recorded in the table below.6. Steps 1- 5 are repeated by using 100g and 150g mass of sphere.

Discussion When the mass of the sphere increases the distance of the sphere’s movement decreases. The greater the mass of an object, the greater the inertia.The greater the mass the more the object tends to remain at rest and resist a change in motion.
Hypothesis is accepted.
Conclusion The greater the mass of an object the greater the inertia produced

Topic : Proprioceptor

PEKA SAINS SPM 1511/3
Aim : To observe the role of proprioceptors in arrange cans in the correct order without looking
Hypothesis :. Proprioceptors helps us to arrange cans in the correct order without looking
Variables : manipulated variable : Number of students responding variable : Ability to arrange cans in the correct order fixed variable : Mass of cans
Apparatus : sand, five copper can of equal size
Procedures : 1. This activity must be done in groups 2. All the five cans must be filled with sand of different weights for example:
Can One Two Three Four Five
Weight of sand 50 g 100 g 150 g 200 g 250 g
3. One of my friend is asked to close his eyes4. His eyes are covered with a piece of cloth.5. The five cans are arranged randomly in front of my friend whose eyes
have been covered.6. He is asked to pick up the cans one by one and arrange the cans
according to their weight either in descending and ascending order.7. Role among group members are exchanged and the step above are
repeated.8. The observations are recorded in the table.
ResultNumber of
Student Ability to arrange in the correct order (Yes /No)
1 Yes
2 Yes
3 Yes
4 Yes
5 Yes
Discussion : Proprioceptors are receptor in our body that sense the position of our body that sense the position of our body
We can arrange can without looking because our body has proprioceptors

Proprioceptors are important because the enable us to be concious of the position and the posture of our body.The receptor in the muscle related to proprioceptore is called stretch receptor.The other function of proprioceptors also enables us to detect the movement of our body without looking.
Hypothesis is accepted
Conclusion : Proprioceptors are receptor that enable us to be conciousabout the movement of our body parts as well as its functions without using our eyesight
