The thing that makes slime making so cool is the chemistry behind it. When you mix the glue and water with the borax, it creates a chemical reaction that turns the mixture into a sticky, gooey substance. It's like magic, but it's actually just science!
Another really cool science project for 5th graders is building a volcano. Who hasn't seen those fake volcanoes in movies and TV shows, erupting with lava and ashes? Well, you can actually make your own version of one of these using a plastic bottle, some clay, and a few other simple materials.
The best part about building a volcano is the eruption - when you mix the baking soda and vinegar, it creates a chemical reaction that makes the "lava" flow out of the top of the volcano. It's like a mini-eruption, and it's really cool to watch!
