Exercise 1
Step 1
1 of 3
**Observation** is the act or the process of **perceiving** a certain object or event in an environment and its surroundings **using human senses** such as *vision (sight), auditory (hearing), tactile (touch), olfactory (smell), or gustation (taste).*
Step 2

Among the choices in this exercise, the statement that best serves as an observation is the student describing the rock as “black” and “shiny” since it was an **inference through visual inspection**.

Therefore, the correct choice is (**4**).

the density of water is $1 g/cm^{3}$
so, the student can fill a cylinder with water and places the plastic beads. beads have density higher than the water $(1.2 g/cm^{3})$ will sink to the bottom of cylinder and beads with $0.6 g/cm^{3}$ density will float.

he will sort them according the variations in densities by using water
Exercise 17
Step 1
1 of 2
pour water to a known level in graduated cylinder and record the volume $V_{1}$, then immerse the irregular sample in water then the level of water goes up, record the new value of volume $V_{2}$. the difference between the two values equals the volume of the irregular sample$V_{S}$.

$V_{S}=V_{2}-V_{1}$

Result
