WE BUILD CUSTOM KITS!
Young students will benefit from the identification activities; however the process that breaks down the sponge requires the use of bleach. It is recommended that the instructor perform this part of the lab.
Students can use the Sponge Spicule Lab Kit to analyze and interpret data from an investigation to provide evidence that animals have traits inherited from parents and that variations of these traits exist in a group of similar organisms.
Students can use the Sponge Spicule Lab Kit to construct an argument that animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
Students can use the Sponge Spicule Lab Kit to apply ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.
Students can use the Sponge Spicule Lab Kit in an investigation to construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment.
During the process when the exterior sponge structures interacts with bleach, 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.
Students can use the Sponge Spicule Lab Kit to model the hierarchical organization of interacting systems that provide specific functions with multicellular organism.
Students can use the Sponge Spicule Lab Kit to identify anatomical structures, showing common ancestry and biological evolution.
During the process when the exterior sponge structures interacts with bleach, students can develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
Students can make measurements of the sponge materials before and after the sponges are immersed in the bleach solution.
