NPR correspondent Geoff Brumfiel tells us, so far antimatter has mostly escaped the detection of physicists.

Exploring properties of matter, motion, force, engineering design process.

Matter, states of matter (solids, liquids, gases), changes in matter.

Matter, states of matter (solids, liquids, gases), changes in matter (physical and chemical).

Properties of matter, density, elements vs. compounds, chemical reactions, photosynthesis.

Students explore how knowledge of the properties of objects (mainly size) can be useful for separating mixtures.

In this Short Activity, learners explore how the application of nano-sized particles or substances can change a bigger material’s properties.

Students do simple tests to observe the properties of water, mineral oil, and corn syrup on the surface of a zip-closing plastic bag to investigate the question: Can liquids that look similar have different properties?

Students squeeze a flexible plastic bottle filled with air and another filled with water to investigate the questions: Is an “empty” bottle really empty? and Can you force the molecules of a gas or a liquid to be closer together?

Dig into the chemical properties and reactions involved in concocting a beloved dessert with a fun look at changing states of matter.
