Graph temperature changes as ice is melted and water is boiled. This disease is caused by legionella bacteria that proliferate in contaminated water supplies. Create different mixtures of polar and nonpolar molecules to explore the intermolecular forces that arise between them. As the equation is manipulated, the amount of each element is shown as individual atoms, histograms, or numerically. No two trials will have the same result so repeated trials are recommended. Explore trends in atomic radius, ionization energy, and electron affinity in the periodic table.
Create a variety of challenge molecules including cyclic molecules and isomers. Each element is classified as a metal, metalloid, or nonmetal, and its state at room temperature is also given. Four materials (aluminum, copper, steel, and glass) are available for the bar. Observe the five main types of nuclear decay: alpha decay, beta decay, gamma decay, positron emission, and electron capture. Observe the effect of gaining and losing electrons on charge, and rearrange the atoms to represent the molecular structure. Explore the relationship between molecular motion, temperature, and phase changes.
Determine the effects of concentration, temperature, surface area, and catalysts on reaction rates. Explore examples of nuclear fusion and fission reactions. B:: stoichiometry mathematically describes quantities in chemical composition and in chemical reactions. 6:: The student will investigate and understand that the phases of matter are explained by the kinetic molecular theory. For O²⁻ = 8 + 2 = 10 electrons. Materials including soap, lemon juice, milk, and oven cleaner can be tested by comparing the color of the pH strips to the calibrated scale. 3:: solve problems using mathematical manipulations including the International System of Units (SI), scientific notation, derived units, significant digits, and dimensional analysis. The amount of greenhouse gases present in the atmosphere can be adjusted through time, and the long-term effects can be investigated. Average Atomic Mass. 1:: The student will demonstrate an understanding of scientific and engineering practices by. Explore relationships between amount, temperature, pressure, and volume for an ideal gas in a chamber with a moveable piston.
Explore the motion of particles as they bounce around from one side of a room to the other through an adjustable gap or partition. Measure the dew point by cooling a bucket of water until condensation forms on the surface.
