Ficou faltando a Data_Avaliacao na opinião do instrutor durante a inserção das Notas.
Tabela de notas:
CREATE TABLE notas (
id_nota INT PRIMARY key,
id_aluno INT,
id_disciplina INT,
valor_nota FLOAT,
data_avaliacao DATE,
FOREIGN key (id_aluno) REFERENCES alunos (id_aluno),
FOREIGN key (id_disciplina) REFERENCES disciplinas (id_disciplina)
);
Segue a correção da inserção:
