Indeed, science is one of the easiest ways to nurture your child’s natural instinct to explore the world around them. Check out our tips and tricks on how to get started on science exploration together!
Science is arguably the easiest way to nurture a student’s natural instinct to explore the world around them, but it can also be one of the messiest and, sometimes, even the most dangerous. Instead of shying away from these explorations, use them as a way to teach students how to contain the mess and minimize the danger.
By having the student research these precautions themselves before beginning an experiment, they’re more likely to retain the information and use it in practice. You’ll also be setting them up to be more independent thinkers.
The classic oil and water in a bottle experiment is still a great way to teach about densities and properties of the different liquids, but don’t wait until the bottle is full to start teaching!
If you put the oil in first, the students can observe the water bubbles fighting to get on top of the oil. Use the time it takes for the two layers to separate to discuss what happened before dropping the food coloring in. The food color will drop through the oil quickly and settle just on top of the water layer. It takes about 12-15 drops of food coloring to break through the surface of the water layer and the mixing of the dye (which does not require the bottle to be moved at all) in the water is mesmerizing!
Allow the students to take videos of this part. This is the stage of the experiment where teachers typically close up the bottles and have students observe what happens when you turn it upside down, but you can take this one step further using pieces of alka-seltzer tablets. When about 1/5 of a tablet is dropped into the bottle, it fizzes in the water and creates a lava lamp effect.
