These growing alligators start at about 4 inches long (approx 10 cm) and grow to about 10 inches (approx. 25 cm) long when placed in water! These water absorbing polymers are great for a class measuring or graphing project or make a super demonstration. Growth is visible within 24 hours, full size in about a week! For an elementary literature connection, see Zack's Alligator, Item BK-200. Color and style may vary.

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s) 2-PS1-2
| Elementary || || Middle School || || High School |
| 2-PS1-2 |
Students analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.
| || MS-PS1-2 |
Students can analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. MS/ETS1.B
A solution needs to be tested, and then modified on the basis of the test results in order to improve it.
| || HS-PS2-6 |
Students will observe and communicate scientific information about why the molecular-level structure is important in the functioning of a material.
Students can conduct simple tests using the Growing Alligators to better understand the rate at which the polymers absorb or evaporate water. Information gathered can be used as evidence to support or refute student ideas about hydrophilic (water-loving) materials. MS-PS1-2
Students can analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. HS-PS2-6
Students will observe and communicate scientific information about why the substance is able to absorb so much water. Further study of the structure of the hydrophilic polymers will help students to understand that the molecular-level structure is important in the functioning of a material.
