وفيما يلي حل تقييمات الأسبوع التاسع ساينس للصف الرابع الابتدائي الترم الأول 2027، والتي جاءت كما يلي 

Grade 4 | Performance Tasks and Assessments | CHAPTER 4: PROPERTIES OF LIGHTEasy Science with Dr-Safaa AbdelrhmanSecond Homework — Week 9

1. When measuring ground temperature using a thermometer, what is the procedure to be followed when measuring the temperature of the ground?

   • Make sure the thermometer bulb touches the ground, and block direct sunlight from hitting it by making a shadow over it with your hand.

2. Give reason: The heat rises in sunny places by the time passing.

   • Because the ground in sunny places absorbs a larger amount of sunlight.

3. Determine the validity of the following statement: Ground in a shaded place is often more humid compared to a sunny place.

   • True. Shaded places receive less sunlight, so the ground is cooler and damper.

4. Explain the cause of shadow formation as you learned from the lesson.

   • An opaque object blocks light, forming a dark area behind it.

5. When do we get the shortest shadow length during the day?

   • At noon.

THIRD: Weekly Assessment — Week 9

Group (A)

1. Choose the correct answer:

   • A very long shadow of objects forms on the ground at: (Noon / Early Night / Early Morning / Midnight)

2. When does a shadow form?

   • When an opaque object blocks light and prevents it from passing through.

3. What happens if the apparent position of the Sun in the sky changes from East to West with respect to shadow extension?

   • The shadow's direction changes from west to east.

4. Explain how we use an infrared thermometer.

   • Hold it at an appropriate distance above the ground without touching the ground.

5. Give scientific reason: Shadows are always formed in the direction opposite to the Sun.

   • Because light travels in straight lines and an object blocks the light.

Grade 4 | Performance Tasks and Assessments | CHAPTER 4: PROPERTIES OF LIGHTEasy Science with Dr-Safaa Abdelrhman

Group (B) — Week 9

1. Choose the correct answer:

   • When we gradually move an opaque object away from a flashlight toward the wall, its shadow size: (Increases / Decreases / Doubles / Remains constant)

2. What happens if Noon sunlight falls on a pole in the school yard?

   • A very short shadow forms directly beneath the pole.

3. Define the sundial.

   • A tool used to tell the approximate time from the regular change in a shadow's position.

4. What is the name of the tool used to measure the temperature of any place?

   • A thermometer.

5. Give scientific reason: Ground in sunny places becomes warmer than ground in shaded locations.

   • Because the ground in sunny places absorbs a larger amount of sunlight.

Group (C)

1. Choose the correct answer:

   • When Sun is at its highest point in the sky (Noon time), object shadows are: (Very long to the West / Very long to the East / Very short directly under the object)

2. What happens if: Early morning sunlight falls on a pole in the school yard?

   • A very long shadow forms and extends toward the west.

3. Give reason: Using an infrared thermometer.

   • To measure temperature without touching the object or ground.

4. What is the name of the tool used to tell time through changing shadow positions?

   • A sundial.

5. Answer:

   • If clouds suddenly disappear and the sky becomes completely clear and sunny, what do you expect will happen to the shadow area on the ground?

   • The shadow becomes clearer and darker.
