Your elementary schooler can use this simple exercise to see how different liquids don’t always mix due to their different densities.
Students who take part in making a density display might be more likely to understand the relationship between mass (how much) and density (how tightly packed). Out of all potential science lessons in the kitchen, this is arguably one of the coolest to look at as well as the easiest to put together.
Show your learners how the different liquids around the house make visible layers when poured into the same container. To run this experiment, let your student choose from an array of common household items (we recommend at least 3 to really see the effect).
You can use anything with different densities, such as:
- Maple syrup
- Liquid soap
- Vegetable oil
- Olive oil
- Rubbing alcohol
- Canola oil
Find a tall glass or clear bowl and gather your ingredients.
Before your student adds any ingredients, ask them what they think will happen. Help them form a hypothesis and write it down so you can help them keep track of their findings.
Then, help them carefully pour even amounts of each of their chosen liquids, starting with the highest-density substances and ending with whatever has the lowest density.
