Criterion A: The topic of the Internal assessment is stated clearly and explained in the introduction

Comment: The student clearly states the topic of the investigation which is to find suitable mathematical models for a chicken egg and comparing them, and further, calculating the volume and surface area of the egg from those models

Criterion A: The introduction includes a general description of the student's approach to the topic and what area of the math curriculum the exploration focuses on

Comment: The student should include an outline of the exploration before the section on modeling the egg. The student should explain the mathematical concepts included in the investigation such as modeling the ellipse, using polynomials, etc.

Criterion A: The conclusion is a summary of the outcomes and a response to the aim of the exploration stated in the introduction

Comment: The conclusion should include a reference to two different models constructed by the student

Criterion A: The use of technology, when applied, is clearly indicated and explained

Comment: The use of the WolframAlpha calculator is justified

Criterion A: The graphs, tables, and diagrams are present in appropriate places (in the body paragraphs, after their descriptive introduction)

Comment: The graphs, and diagrams are present right next to their descriptions

Criterion B: The graphs, tables, and diagrams are labeled (titled and numbered) at the bottom

Criterion B: Key terms/variables are defined and explained when first introduced

Criterion B: Key terms/variables are defined and explained when first introduced

Criterion B: The main concepts are described in the introduction

Comment: The introduction lacks a description of the used mathematics, therefore brief explanations of the main concepts applied are also missing from the introduction. The student should describe the subjects such as the volume, surface area, ellipse, interpolation, integration, etc. in the introduction. This would ensure that they understand the mathematical concepts well
