Why is my Google Search Results page different to everyone else's (and not working)

I'm struggling with something on Android Chrome.

When I do a Google Search I am seeing a different screen than most friends. They have tabs for the different categories and the Search Tools on the left. I am seeing the different screen below plus when I click the wrench for search tools because I only want to see results for the last week. I get the screen below. I can't figure out how to change the time option. Clicking it is not working. I have managed to get it to work a couple of times but I don't know how

It's the same on my Galaxy Nexus and N7
