how to move score system through scenes with SceneManager.MoveGameObjectToScene

i'm making a 2d game that contains na extra scene. i want to move my score system to the extra scene along with my player (he's is not going to the scene, there is a new one there), but i want to keep the points. does anyone know how to do that? here is my score system script:

     public Text score;
 public Text highScore;
 public Text finalScore;
 public float scoreCount;
 public float highScoreCount;
 public float finalCount;
 public float pointsPerSecond;
 public bool scoreIncreasing;
 public Text eyeCount;
 public float EyeCount;

 private PauseController pause;

 void Start () 
 {
     pause = FindObjectOfType<PauseController> ();
     SeteyeCount ();
     EyeCount = 0;

     if (PlayerPrefs.HasKey ("High Score")) 
     {
         highScoreCount = PlayerPrefs.GetFloat ("High Score");
     }
 }

 void Update () 
 {
     if (pause.paused) 
     {
         return;
     }

     if (scoreCount + EyeCount > highScoreCount) 
     {
         highScoreCount = scoreCount + EyeCount;
         PlayerPrefs.SetFloat ("High Score",highScoreCount);
     }

     if (scoreIncreasing == true) 
     {
         scoreCount += pointsPerSecond * Time.deltaTime;
         Time.timeScale = 1;
     } 


     score.text = "Score: " + Mathf.Round (scoreCount);
     highScore.text = "High Score: " + Mathf.Round (highScoreCount);
     finalScore.text = "Final Score: " + Mathf.Round (scoreCount + EyeCount);
 }

 public void SeteyeCount ()

 {
     eyeCount.text = "Eyes: " + EyeCount.ToString ();
 }

here is my script that loads the extra scene:

 public Text CountDownText;
 public Text displayCountDown;


 private float CountDown = 5;

 void Update ()
 {
     if (CountDown > 0) 
     {
         CountDown -= Time.deltaTime; 
         CountDownText.text = "Time: " + CountDownText.ToString();
         displayCountDown.text = CountDown.ToString ("F0");
     } 
     if (CountDown <= 0) 
     { 
         SceneManager.LoadScene ("Extra 1");
         this.enabled = false;

     } 
 }
