How to have a Next Level and Game Over pop up in scene please help!

Hey everyone. I am kind of stuck and was wondering if anyone can help me on this or point me in the right direction. I have a game in which it is level based. Each level I have is a different scene. Is it possible to create a pop up within a scene for next level and game over? Like flow free when you complete the level this comes up:

I do not want to create separate game over and next level scenes. Is something like this possible? And if so, would this be applied to every scene? Or can I make it within one scene and have a script to apply it to every scene? ANY help with this or pointing me in the right direction would be GREATLY appreciated. Thank you!

Well you can play with UI.You create a panel and you can deactivate it,then when you end your level you can enable it via script something like this

Look this

using UnityEngine;

using UnityEngine.UI;

using System.Collections;

public class PlayerController : MonoBehaviour {

public float speed;
public Text countText;
public Text winText;
private Rigidbody rb;
private int count;
public AudioSource audio1;
public GameObject EndPanel;//This gameobject is the panel

void Start ()
	rb = GetComponent<Rigidbody>();
	count = 0;
	SetCountText ();
	winText.text = "";
	EndPanel.SetActive (false);//This keep the panel inactive

void FixedUpdate ()
	float moveHorizontal = Input.GetAxis ("Horizontal");
	float moveVertical = Input.GetAxis ("Vertical");

	Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

	rb.AddForce (movement * speed);

void OnTriggerEnter(Collider other) 
	if (other.gameObject.CompareTag ( "Pick Up"))
		other.gameObject.SetActive (false);
		count = count + 1;
		SetCountText ();

void SetCountText ()
	countText.text = "Count: " + count.ToString ();
	if (count >= 12)
		winText.text = "You Win!";
		EndPanel.SetActive (true);//You win the game so the panl is active
