STEAM Color Explorations
Mad Science Week continued today with three STEAM Color Explorations.
1.Oil & Liquid Watercolor Exploration: We provided different trays with a base of oil, Colorations® Liquid WaterColors, & pipettes. We invited the children to take the pipettes, fill them up with colored liquid water & drop it into the oil to explore what happens.
Through this exploration they were able to explore how oil remains separate from the water because it lacks polarity & floats because it’s less dense. We explained that when you have two objects that are the same size but different weights, the one that weighs more has more matter packed into it. It is denser. A good way to tell if something is more or less dense than water is to put it in water. If it sinks, it’s denser, if it floats, it’s less dense.
2. Special Effect Liquid WaterColors: We provided Coloration Liquid WaterColors, Pipettes, & Rubbing Alcohol. The children first painted on poster paper with the liquid watercolors & then they dropped rubbing alcohol and watched the colors transform right before their eyes.
Through this invitation children are able to see even in art when you combine different materials & elements such as liquid watercolors + rubbing alcohol you can do science in art!
3. Color Fizzers Exploration: In our Discount School Supply Tuff Tray we place various sized beakers filled with water & provided Steve Spangler Color Fizzers™ to explore primary colors, create even more color combinations, & experience a solid material fizz into a liquid state.
When the fizzers are dropped into water it dissolves & adds vivid colors to the liquids because they contain a citric acid (as in citrus), sodium bicarbonate (plain baking soda), & and a binder. Citric acid & sodium bicarbonate react in water to release carbon dioxide (CO2) gas. That’s how we saw the fizzing bubbles & vivid colors.
