• picture 1

It is late afternoon. Where would you expect to find the sun and the shadow made from the school's flag pole? 

• The sun should be low in the west, the flag pole shadow should be stretched eastward. 
• The sun should be low in the east, the flag pole shadow should be stretched westward. 
• The sun should be low in the north, the flag pole shadow should be stretched southward. 
• The sun should be low in the south, the flag pole should be stretched northward. 

Rachel has been sitting on the beach reading her book. She noticed that the sun's shadow is directly under her beach umbrella. What time if day is it?

The basketball goal on the school playground casts a long shadow. What time of day could it be?

• Noon, the sun is overhead and objects cast short shadows or no shadow at all. 
• Morning or evening, both times the sun appears low in the sky and objects cast long shadows. 
• Morning, that is the only time you can see a shadow on the playground. 

The length of a shadow cast behind an object is determined by-----

• just the length of object
• the length of the object and angle of the sun
• the type of clouds in the sky and angle of the sun
• the time of the year and the type of clouds in the sky

The fourth graders made sundials in art. The art teacher wants to know when the sun will be straight up in the sky. What should the students tell her?

• 12 o'clock, noon
• 6 o'clock in the evening 

A telescope is a valuable tool for astronomers. The purpose of a telescope is to gather light for--------

• magnifying microscopic objects 
• rotating large objects
• minimizing tiny objects
• magnifying far off objects

How does a telescope help us to study the objects in outer space? 

• A telescope gathers more light than the human eye and magnifies the objects to make faraway objects seem closer and brighter. 
• A telescope is longer than a magnifying glass and can reach far into space. 
• A telescope has diagrams of planets and stars already drawn on the glass to help students make identifications. 
• A telescope makes objects appear farther away than they really are.
