An insulated beaker of hot water is connected to a beaker of cold water with a conducting bar, and over time the temperatures of the beakers equalize as heat is transferred through the bar. Determine how the water moves from one location to another, and learn how water resources are distributed in these locations. Follow the steps of the proton-proton chain, CNO cycle, and fission of uranium-235. Salt can be added to the water to see its effect on the freezing point of water. Each element is classified as a metal, metalloid, or nonmetal, and its state at room temperature is also given. Build a glucose molecule, atom-by-atom, to learn about chemical bonds and the structure of glucose. Molecules of different gases can be compared. Click any Gizmo title below for more information. Data can be interpreted visually using a dynamic graph, a bar chart, and a table. For each completed molecule, write the chemical formula and, if the molecule is included in the database, observe the 3D structure. In this followup to the Coral Reefs 1 - Abiotic Factors activity, investigate the impacts of fishing, disease, and invasive species on a model Caribbean coral reef. Explore trends in atomic radius, ionization energy, and electron affinity in the periodic table.
7:: The student will investigate and understand that thermodynamics explains the relationship between matter and energy. Drop a chunk of material in a beaker of water and observe whether it sinks or floats. Discover trends in atomic radii across periods and down families/groups of the periodic table. Tiles can be flipped, and answers can be calculated once the appropriate unit conversions have been applied. Construct a DNA molecule, examine its double-helix structure, and then go through the DNA replication process. Along the way you will learn about chemical equations, acids and bases, exothermic and endothermic reactions, and conservation of matter. 3:: use models and simulations to visualize and explain the movement of particles, to represent chemical reactions, to formulate mathematical equations, and to interpret data sets. Plot both stable and radioactive isotopes on a graph of neutrons vs. protons, and explore how the neutron:proton ratio of stable isotopes changes from lighter to heavier elements. Molar masses of reactants and products can also be calculated and balanced to demonstrate conservation of mass.
