Observing Using Smell

Beginning biologists explore passive transport through two demonstrations and a hands-on inquiry. Spray air freshener from one spot in the classroom and have class members raise their hands as the scent reaches them. Also, place a teabag...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe how...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science activity introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a chemistry...

A demonstration of elephant toothpaste hooks pupils' interest as they complete multiple experiments with colors, smells, bubbles, and more. By the end, they understand the differences between physical and chemical changes in the world...

Your enthusiastic chemists will flip over this entertaining video about matter and its chemical changes! Take an in-depth look into what chemical changes are and the evidence that is observed, such as color, smell, and heat. Then,...

Trying to learn through diffusion rather than simply studying the material rarely works for scholars. This simulation helps make learning diffusion fun. Pupils add a drop of dye to water and observe the diffusion as the molecules bounce...

Get moving! Science scholars observe the effects of temperature on kinetic energy in an impactful interactive. Individuals control a sliding temperature switch and observe the motion of gas particles that results from the change.

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

How do transcription factors change the function of a cell? Learn how three similar cells find different functions based on their locations and the number of triggers available. Observe an animation of the process of assigning a trait...
