Laravel Collection Loop转到另一个Collection

How to loop the eloquent collection from one to another? I'm just getting first line of array. I have more than 4 array in the collection.

$queries = Students::where('year',"=", 1)->get();
$students = new Students();
foreach ($queries as $query) {
    $students->name = $query->name;
    $students->faculty = $query->faculty ."Add something";
    $students->year = $query->year;
}
dd($students);

    I want to change the collection a bit before I print to json. For example, I want add something behind the faculty

    Use the transform() method to modify collection:

    $students = Students::where('year', 1)->get();
    $students->transform(function($i) {
        $i->faculty = $i->faculty . 'add something';
        return $i;
    });
    

    You also can use resource classes to transform the data before returning JSON response.
