In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
