Distillation demonstration sets show the separation of liquid mixtures by boiling point, a foundational concept in both chemistry and chemical engineering. Flame test kits allow students to identify metal ions by the characteristic colors they produce in a flame.

Magnetic models allow for quick assembly and disassembly during live demonstrations. Classroom sets with enough atoms and bonds for each student or lab group to build molecules simultaneously make the learning experience hands-on rather than purely observational. Models are also valuable in biochemistry for illustrating amino acid structures, protein folding concepts, and the geometry of enzyme active sites.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- Q: What is the difference between a scientific model and a specimen? --\u003e\n\u003cdiv itemtype=\"https:\/\/schema.org\/Question\" itemprop=\"mainEntity\" itemscope=\"\" class=\"faq-item\"\u003e\n\u003ch3 itemprop=\"name\"\u003eWhat is the difference between a scientific model and a specimen?\u003c\/h3\u003e\n\u003cdiv itemtype=\"https:\/\/schema.org\/Answer\" itemprop=\"acceptedAnswer\" itemscope=\"\"\u003e\n\u003cdiv itemprop=\"text\"\u003e\n\u003cp\u003eA scientific model is a manufactured teaching tool that represents a concept, structure, or process — such as a volcano cross-section, a molecular model, or a globe.

A volcano model demonstrates how magma moves through layers of rock — it's a teaching tool. A basalt specimen is an actual piece of igneous rock that students can hold, weigh, and test.
