The task is to identify which object in each box is more dense than the other. Density refers to how much mass is packed into a given volume. Objects with higher density will sink in objects with lower density.
Let's go through each box step by step:
1.
Styrofoam ball vs. Rock: A rock is much heavier for its size compared to a Styrofoam ball. Therefore, the rock is more dense.
2.
Water vs. Ping pong ball: A ping pong ball floats on water, indicating it is less dense than water. Therefore, water is more dense.
3.
Gold Ring vs. Pencil: Gold is a very dense metal, while a pencil (usually made of wood and graphite) is much less dense. Therefore, the gold ring is more dense.
4.
Water vs. Oil: Oil floats on water, indicating it is less dense than water. Therefore, water is more dense.
5.
Bathtub Toys: Both toys are floating, but typically, toys designed to float are less dense than water. Since both are similar in design, we can assume they have similar densities. However, if we must choose, the toy with more material (heavier one) would be more dense.
6.
Large Log vs. Small Rock: A large log is usually less dense than a small rock because wood is less dense than stone. Therefore, the small rock is more dense.
Final Answer:
- Rock
- Water
- Gold Ring
- Water
- (Assuming the heavier toy)
- Small Rock
