In today’s experiment, we are going to get to find a hidden treasure. But first we are going to hide it 🙂 Once we “hide” the treasure, we are going to use science to reveal the treasure. If you’ve done other activities with us, you may remember that we’ve already learned about and experimented with chemical reactions. We are going to once again use chemical reactions!
Let’s start with the idea of a chemical reaction. Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules. That’s it. What molecules are they? How do they interact? What happens? The possibilities are infinite. (Kiddos in grades 3-5, click here to read some more information.)

Time to “hide the treasure”.
Well, technically, before we can hide it, we need something to hide. You can use anything small, ideally plastic, something that won’t be ruined if it gets wet. Some ideas are a coin or a small plastic figurine like a tiny dinosaur or Lego man. Once you have “your treasure”, it’s time to watch the video. It will walk you through hiding & revealing your treasure! Materials: 1 cup baking soda, water, food coloring, bowl, spoon, vinegar
