Discover how the moon gets its craters with this engaging STEM activity! Children will use dough and marbles to simulate meteoroid impacts, creating their own lunar landscape and understanding a key astronomical phenomenon.

• Playdough or homemade dough (e.g., salt dough) • Marbles (various sizes) • Tray or flat surface (to contain dough and marbles)
Getting Started
First, prepare your 'moon' by shaping the dough into a ball or a flat, thick disc. Place it on a tray or flat surface to catch any stray marbles and make cleanup easier.
How to Do This Activity
• Explain to your child that the dough ball represents the moon and the marbles represent meteoroids, which are small rocks in space. • Invite your child to drop the marbles onto the dough moon. Encourage them to drop marbles from different heights and with varying force. • Observe together what happens when the marbles hit the dough. Point out the indentations left behind. • Explain that these indentations are like the craters on the real moon, formed by meteoroids crashing into its surface over millions of years. • Discuss how the size and depth of the craters might change based on how the marble was dropped.
Tips for Parents
• Encourage open-ended exploration rather than focusing on a perfect outcome. The goal is understanding the concept. • Ask questions like: "What do you think will happen if you drop it from higher?" or "Why do some craters look different from others?" • Connect this activity to real-world events, such as the Chandrayaan landing, to spark further interest in space. • Use simple language appropriate for your child's age to explain complex ideas.
Ways to Extend
For older children, you can introduce a ruler to measure the diameter or depth of the craters. Experiment with different types of 'moon' surfaces, such as a thin layer of flour on a hard surface, to see how different materials react to impact. Research famous craters on the moon or other planets together, looking at pictures and discussing their names and sizes.
