Science 3 First Quarter Examination

Ella and Alliyah are working with clay in art class. They both have a piece of clay. Mia tries to make a ball, but Alliyah tries to make a snake-like shape. Which property of clay are they testing?

• Color

• Texture

• Malleability

• Weight

Grace is experimenting with different materials in science class. She takes a piece of glass and gently taps it with a small hammer. The glass breaks into small pieces. What property of the glass does this experiment demonstrate?

• Transparency

• Hardness

• Brittleness

• Flexibility

Arjay is exploring different rocks he found on the beach. He notices that one rock is very smooth, while another rock feels rough. What property of the rocks is Lucas most likely comparing?

• Color

• Weight

• texture

• Shape

When a material is stretched or compressed and returns to its original shape after the deforming force is removed, it is said to be elastic. Which of the following materials exhibits high elasticity?

• Plastic

• Rubber

• Aluminum

• Glass

Electrical conductivity is the ability of a material to conduct electricity. Which of the following materials is an excellent conductor of electricity?

• Styrofoam

• Silver

• Cotton

• Wax

Which of the following materials is known for its exceptional durability, making it highly suitable for applications requiring strength and resistance to wear and tear?

• Rubber

• Glass

• Steel

• Paper

Ductility is the property of a material that allows it to be stretched or drawn into a wire or a thin filament without breaking. Which of the following materials is highly ductile?

• Concrete

• Copper

• Ceramic

• Wood

Caleb is experimenting with different materials to see which ones conduct electricity. He finds that a paperclip allows electricity to flow through it, but a cotton ball does not. What conclusion can Timmy draw from this experiment?

• Paperclips are good conductors of electricity.

• Cotton balls are dangerous because they conduct electricity.

• Paperclips and cotton balls have the same conductivity.

• Timmy's experiment was a failure.

Cristelle is playing with two liquids, water and honey. She notices that water flows quickly from one cup to another, while honey moves very slowly. Why does honey move more slowly than water?

• Honey is a solid, not a liquid.

• Honey is thicker and stickier than water.

• Honey is lighter than water.

• Water is too cold.

FRancheska is watching a river flowing, and she notices that some parts of the river are fast-moving, while others are slower. What might cause some parts of the river to flow faster than others?

• The river is frozen.

• The river is too wide.

• Rocks and obstacles in the river.

• The river is magic.
