Experiment Title: The Metal Hedgehog
What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: We wanted to learn how to make a metal hedgehog. Metal that forms spikes and looks like a hedgehog when you put it in a solution.
What was your hypothesis?: Our hypothesis was that the metal spikes would form when we put it in the solution.
What materials did you use in your experiment? List them all.: Tin Chloride
A metal ball (tiny)
Test tube
a Petri dish
What procedure was followed? Provide a brief description of the steps you followed during your experiment.: 1. Put the solution in a cylinder tube. Make sure to wear gloves.
2. Put the lid on the solution and shake it up.
3. Pour the solution into the dish and put in the metal ball.
4. Then you wait.
5. The ball forms spikes.
What were the results of your experiment?: The metal ball formed spikes on it when it was placed in the solution.
What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?: Our hypothesis was correct. But I thought the metal ball would grow bigger than it did.
Spend a few minutes learning about the scientific principles involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.: I learned how to make a metal ball hedgehog. The solution mixed with something in the metal and pulled out parts of the metal to create points.The atoms from the solution and the atoms from the metal ball were attracting each other.
Though I thought the metal ball would grow bigger, I realized that it couldn’t be bigger because you can’t just grow more metal if it’s not already there.
