Crushing a ketchup packet / Activity Analysis

Science

• The child learned about the properties of matter, specifically the fluid-like behavior of ketchup.
• They observed the concept of pressure as they applied force to the ketchup packet.
• They discovered the concept of viscosity as they noticed how the ketchup flowed or didn't flow out of the packet.
• The child also learned about potential energy and how it is converted into kinetic energy when squeezing the packet.

For continued development, encourage the child to explore other substances with different viscosities and compare their behavior when applying force. They can also investigate the effects of temperature on the viscosity of ketchup or other liquids. Additionally, they can research and learn about the science behind food packaging and why some packages are easier or harder to crush.
