Science Experiments: Oobleck, Polymers, and Chemical Reactions

Science

• The student learned about non-Newtonian fluids, understanding that oobleck behaves both as a liquid and a solid, and was able to observe this firsthand during the experiment.
• Through the Blake snake experiment, the student gained insight into chemical reactions, specifically the combination of baking soda and vinegar to produce carbon dioxide gas, which inflates the snake.
• The activity fostered an understanding of polymers and cross-linking, as the oobleck demonstrated elastic and viscous properties due to cornstarch suspensions.
• By engaging in both experiments, the student developed critical thinking skills and the ability to apply the scientific method, including making observations, forming hypotheses, and conducting experiments to test their hypotheses.

For continued development, encourage the student to explore other non-Newtonian fluids, such as silly putty or cornstarch slime. They can also investigate the concept of chemical reactions further by experimenting with different household ingredients to observe how they react with one another. Encouraging the student to document their experiments and observations in a science journal can help reinforce their learning and critical thinking skills.
