Actividades de refuerzo y repaso Semana Santa

Os dejo aquí las actividades de refuerzo y apoyo de Semana Santa. Os recuerdo a todos que los alumnos con la asignatura suspensa deberán mandarme estas actividades de forma obligatoria por class dojo o a mi mail alteapenadesmaestre@gmail.com . Para los demás alumnos será opcional. 

La idea es ir haciendo las tareas poco a poco y mandarlas poco a poco. 

Yo estaré disponible mañana durante la mañana para resolver dudas y también me volveré a conectar el miércoles 8 de Abril.

Corrected exercises: 

Page 87 exercise number 1 : 

1.-What does electrically neutral mean? 

An Object is electrically neutral when it has the same number of positive and negative charges. 

2.-Cables are usually made  of coper wire and wrapped in plastic . Why do you think they are made this way ? 

Because the copper is a conductor and allow the electrical charges to move from the generator to all parts of the circuit. The plastic is an insulator and prevent us to be hurt by electrical currents.

I leave you a simple  game about electrical circuits.
