Penetrometer facts for kids
A penetrometer is a special tool used to check how strong or firm something is. Think of it like testing how squishy or hard a material feels.

What Does a Penetrometer Do?
This tool is often used to test soil. It helps scientists and engineers understand the ground. They might drop the penetrometer or push it into the soil.
Testing Soil Strength
When a penetrometer goes into the ground, it measures how deep it can go. This tells us if the soil is strong enough. For example, engineers use it to see if the ground is firm enough to build a road or a building on.
Measuring Soil Moisture
Scientists also use penetrometers to find out how much moisture (water) is in the soil. This is important for understanding how plants grow or how water moves through the ground.
Penetrometers in Space
Believe it or not, penetrometers have even traveled to space! They were used on space probes, like the Cassini-Huygens probe. These probes used penetrometers to measure the moisture in the soil on other planets. This helps us learn more about distant worlds.
