In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.
In this physics activity, learners build their own rockets out of film canisters and construction paper.
In this activity, learners follow simple directions to explore and create platonic solids.
In this activity, learners will experiment with different materials that can melt and change ice.
This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.
This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.
In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.
In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.
In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.
This is an activity about friction as well as kinetic and potential energy.
This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.
Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.
This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.
