Grade 3: The Water Cycle

Last week our grade 3 students learned and talked about the Water Cycle.They understood that this is the process when water keeps going around and around.
This cycle is made up of 4 main parts:

• evaporation (and transpiration)
• precipitation
• condensation
• collection

They also practice with this animation:

Grade 4: Phases of the moon

The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. From Earth we see the Moon grow from a thin crescent to a full disk (or full moon) and then shrink back to a thin crescent again before vanishing for a few days.

The Moon phases are produced by the alignment of the Moon and the Sun in the sky.

What is the phase of the moon?

The changing shape of the bright part of the Moon that we see is called its phase.

What causes the different phases of the Moon?
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles. These are called "phases" of the Moon.

Our children sang this song to remember the 8 phases of the moon.They liked it a lot:

Grade 4: Shadows Review

All grade 4 students reviewed and learned more about shadows. They recalled that a shadow is an area where direct light from a light source cannot reach due to obstruction by an object.It occupies all of the space behind an opaque object with light in front of it.

What does the position of the sun affect?
The position of the sun affects the postion and size of the shadow.

What happened when the sun is in front of you?
The shadow forms behind you.

They were shown an animation to practice forming shadows. They had a good time playing with this game:
