Super Slurper
In the polymer Olympics, this substance would win a gold medal! It can soak up and hold up to 3000 times its weight in water! In this activity, students test the polymer to see if salt interferes with the polymer’s efficiency.

Using Mathematics and Computational Thinking 6. Constructing Explanations and Designing Solutions 7. Engaging in Argument from Evidence 8. Obtaining, Evaluating, and Communicating Information ||Next Generation Science Standards||Grade 4||Science and Engineering Practices|||Develop a model to describe that matter is made of particles too small to be seen. [ Examples: adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, & evaporating salt water.]||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Make observations & measurements to identify materials based on their properties. [Examples of properties: color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, & solubility; density is not intended as an identifiable property.]||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Conduct an investigation to determine whether the mixing of two or more substances results in new substances. ||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Science and Engineering Practices: 1.
