Three clear containers such as drinking glasses or mason jars. Browse our Science Fair Kits category for more project ideas and easy-to-use products. Required fields are marked *. Investigate which pH and chemical levels are most common in your area. When a non-polar solvent such as vegetable oil moves over it, it will not interact, and therefore will not move. More Easy Science Experiments for Kids. Place one coffee filter in each container so that the bottom of the coffee filter is submerged in the solvent but the solvent DOES NOT touch the dots of marker ink. Sciencing. 6 Easy Biology Science Experiments for Kids Letâs dive into studying life and living organisms with a new set of biology experiments for kids! All Rights Reserved.

This movement of water molecules is called “osmosis.” In order to examine the process of osmosis and observe how it works, we can look at what happens to gummy bears when they are left to soak in different solutions overnight. -Human Body & Anatomy Save on Shipping with code SILVER20. In this experiment, we replicated these conditions to produce “rain.” First, we let the heated water form water vapor inside the jar. Electricity Projects. Scientific inquiry starts with an observation followed by the formulation of a question about what has been observed. One of the properties of water is that it can exist in different phases. The second property is cohesion. Fashion your own bouncy balls with this recipe to see how various shapes bounce differently. Want to get the printable instructions for this?
