Same Topic, Different Facts is a free printable Grade 1 English worksheet on finding what two texts share and where they differ, aligned to Common Core standard RI.1.9. It prints 2 questions with an answer key on its own sheet of paper, in 25 versions, 24 of them with different questions, so no two pupils in the class work from the same page. Print it from the browser or download it as a PDF — no account, no email.

Why Tall Buildings Do Not Fall Over

A tall building needs a wide, deep base. The base is called a foundation. It spreads the weight into the ground. Wind pushes hard on a tall building. Inside, a strong core of concrete runs from the bottom to the top like a spine. The core stops the building bending too far. The tallest buildings sway a little in strong wind. That is meant to happen. A building that could not bend at all would crack.

  2. 2. How is a tall building like a bridge?

How a Bridge Stands Up

A bridge has to hold its own weight and the weight of everything crossing it. The simplest bridge is a beam: a flat piece laid across a gap. A beam bridge cannot be very long, or it sags in the middle. An arch bridge is curved. The curve pushes the weight out to the ends, where the ground is solid. That is why arch bridges can cross wider gaps.

  1. 1. How are beam bridges and arch bridges different?
  2. 2. How are beam bridges and arch bridges alike?

Set 3. Prints on its own sheet.

  1. 1.1. A building sends weight down into a foundation; an arch sends it out to its ends. 2. Both have to carry weight and both have to stand up to pushing forces.
  2. 2.1. A beam is flat and sags if it is long; an arch is curved and can cross more. 2. Both cross a gap and both must hold their own weight and the weight crossing them.
