101Describe why a material is an appropriate choice for part of a bridge.
204Describe a change to a particle model that will show the atoms with more thermal energy.
301Relate the amount of energy in a seismic wave to the wave's amplitude.
404Analyze a model bridge to determine the loads on the system and describe an advantage and a disadvantage of making a design change.

604Complete a table showing the percentages of genotypes for a cross between two plants that are heterozygous for a particular trait.
702Evaluate two design solutions to determine an advantage of one solution over the other.
805Describe the separation process for creating the desired shape of an object and describe the finishing process for that object.
904Analyze particle models of two gas samples and determine that the samples differ in temperature.
1007Order a set of objects from least to most dense given the mass and volume of the objects.
1101Interpret a model of the Sun-Earth system to explain the cause of the cyclical pattern of the seasons.
1202Analyze force models to determine whether the speeds of objects are changing.
1304Describe how a change in the amount of Arctic ice in polar regions is most likely to affect a species that lives in these regions.
1404Interpret a model to determine how energy from the Sun and Earth's gravity affect the cycling of water.
1502Determine which object has the largest potential energy based on the mass and relative position of the objects.
1605Describe one advantage and one disadvantage of selecting traits artificially in a species.
1702Identify a factor that can limit competition between different species living in the same area.
1802Use a model to determine the part of a plant cell that produces sugars.
1906Identify an example of heat being transferred by conduction.
2005Determine why air on Earth circulates between the equator and the poles.
2105Determine the size of the Sun relative to the planets in our solar system.
2203Select the appropriate safety equipment and tools needed to construct a prototype.
2303Compare the strengths of the electric forces between pairs of charges.
2403Determine the body system that directly controls when muscles contract.
2503Determine whether parts of a vehicle are structural, propulsion, or control subsystems.
2608Determine the next step in a procedure for separating a mixture, and identify evidence that shows a substance is a mixture.
2702Complete a model to show the force that keeps a planet in orbit around a star, and identify that force.
2805Classify part of a transportation system according to the universal systems model.
2904Analyze a diagram to determine the youngest rock layer that was present when a fault formed.
3005Analyze a graph to determine a result of changes in atmospheric carbon dioxide levels over time.
3105Determine that genetic differences in individuals of the same species result in different traits.
3202Determine the relationship between a plant and an insect and describe that relationship.
3304Describe how attracting insects can increase the probability of a plant reproducing.
3402Select an advantage of a plant reproducing sexually and an advantage of a plant reproducing asexually.
3501Analyze fossil record data to describe fossils found in different time periods, and describe evidence that could show a relationship between certain plants and insects.
3602Determine that an area in New England was once covered by glaciers based on a description of the area.
3706Analyze the results of an investigation to determine whether a reaction was endothermic or exothermic, and show how the results should be organized in a lab notebook.
