A seventh grade class is studying the solar system. A small group of students wanted to expand their studies to include the formation of black holes. The classroom teacher meets with this group on a daily basis to discuss their progress and offer additional help. This is an example of Tier in the RtI model. a. I b. III c. All tiers d. IV

The correct answer is letter "B": III.

Explanation:

The Response-to-Intervention (RTI) model is an educational approach provided to low-grade students by which teachers attempt to find out what children might be struggling with and based on the issues found teachers take different actions that could help students and their different forms of learning.

The RTI model is divided into three (3) tiers: Tier I (The Whole Class), Tier II (Small Group Interventions), Tier III (Intensive Interventions).

In Tier III, children require intensive intervention because they have gone through the previous two tiers with no results. Intensive intervention requires everyday sessions tailored for students and continuous evaluation to determine if additional help could be necessary.

Thus, the small group of the class that is receiving specialized classes on Solar System everyday, represents educational help at the tier III in the RTI model.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
