Problems with Internet Explorer

My blog is https://teacherblogspot.com/

I am having difficulty in Internet Explorer with my posts being centered when I want them to be justified like in Firefox and Safari. I noticed that this problem is solved when I remove all of the pictures from the left sidebars except the social media tools. I really want to have all of the pictures there though. Also none of the links on my sidebars work except the twitter and pinterest button.

Please HELP!
