We are learning about rocks in science.
We learned that when observing a rock, scientists use their senses.
They look with their eyes. Feel with their hands, Smell with their noses.
They also perform a scratch test. Which rock is harder? The one that makes a scratch in another rock is the hardest.
What about a scratch test with white or black paper? What happens?
We learn about a rock's properties with these exercises.
Rock properties include: color, shape, size, texture, sheen and weight.
Using a magnifying glass helps us see more details, too.
