Core Skills Analysis
Science
- Explored the properties of non-Newtonian fluids by mixing cornstarch and water, understanding how the substance behaves as both a solid and a liquid under different conditions.
- Observed physical changes and states of matter, learning the difference between solids and liquids through hands-on experimentation.
- Developed an understanding of viscosity and how some materials do not fit neatly into traditional categories of matter.
- Practiced the scientific method by hypothesizing about the mixture’s behavior and testing the effects of pressure or movement on the substance.
Tips
To deepen understanding of this fascinating mixture, encourage your student to experiment with different ratios of cornstarch to water and record how the behavior changes. Discuss real-world examples of non-Newtonian fluids such as ketchup, quicksand, or blood to connect the activity to everyday life. Try incorporating quantitative measurements like timing how long it takes the mixture to flow or measuring its thickness to introduce basic data collection and analysis. Finally, have your student draw or write about the observations and their hypotheses to integrate scientific literacy with the hands-on experience.
