When dry, these six little dinosaurs will all fit easily in the palm of your hand...but when placed in water, they'll absorb many times their own weight in water. Made of a super-absorbent polymer, our green Gro-Beast Dinosaurs start at about 1 inch long and grow to over 4 inches each! Each package contains six different types of dinosaur. A wonderful way to work on variables, measurements, mass, volume, and more. Dinosaurs will shrink back to their original size as they dehydrate. We recommend using distilled water for best results, but why not try submerging a few in other liquids to see how their growth changes?
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 Large Gro-Beast Dinosaurs 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.
