Learn about properties of matter through engaging, bitesize animated videos. There are many videos organised into these chapters: solids liquids and gases, elements compounds and mixtures, atomic structure, periodic table, ionic bonding, covalent bonding and metallic bonding.
This article explains how the ice and snow of the polar regions fit in the global water cycle and includes links to professional development resources.
Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.
This video segment, adapted from ZOOM, explores how sound waves travel differently through solids than through air, in this case, a metal clothes hanger.
This video segment from IdahoPTV's D4K explains and gives examples of the 4 states of matter: solid, liquid, gas, and plasma.
Have you ever wondered how some insects are able to "skate" on the surface of water? We will learn about how intermolecular forces make this possible. We will also cover liquids, solids, mixtures, and phase changes.
Watch the ZOOM cast discover which insulator -- newspaper or aluminum foil -- is better at keeping an ice cube frozen longer.
Four unit plans provide opportunities for in-depth explorations of important foundational climate concepts -- weather, water as a solid, liquid and gas, and the water cycle -- that are appropriate for K-2 and 3-5 learners. These unit plans incorporate many of the lessons highlighted in other articles in this issue of the online magazine Beyond Weather and the Water Cycle. The magazine is structured around the essential principles of the climate sciences.
How can you pick up an ice cube with a string? Watch this video segment adapted from ZOOM to see how salt can help.
Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids. Several types of fluid behaviors are described Bingham plastic, Newtonian, shear thinning and shear thickening along with their respective shear stress vs. rate of shearing strain diagrams. In addition, fluid material properties such as viscosity are introduced, along with the methods that engineers use to determine those physical properties.
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
