Val_loss is very high (over 100)

I'm trying to create a neural network for image classification. This is my Model summary. I have done normalization to my dataset and shuffling to my data. . When I run model.fit the val_loss is very high sometimes close to 100 whereas my loss is less than 0.8

When you don't normalize test data, validation loss will be very high when compared to training data that was normalized. I used simple mnist model to demonstrate the point of normalization. 

(x_train, y_train), (x_test, y_test) = mnist.load_data()
# this is to demonstrate the importance of normalizing both training and testing data
x_train, x_test = x_train / 255.0, x_test / 1.

When we don't normalize test data where as training data was normalized, training loss is loss: 0.0771 where as loss during test is 13.1599. Please check the complete code here. Thanks!
