Where Did the Ice Go?

Where Did the Ice Go? Worksheet: Matter is conserved (Grade 4 Science, TEKS 4.5E)

Students compare a sealed bag of ice on a scale with the same bag of water an hour later, sort what stayed the same and what changed, then circle answers that show the mass stayed 200 grams. The page teaches the idea first, so no prior lesson is needed, and every answer is on the page.

What's Inside

• A short teach box on matter, mass, solids, and liquids
• Two pictures: a bag of ice and the same bag of water on a scale, both 200 g
• Part A: write S (stayed the same) or C (changed) for four things, first one done
• Part B: three circle the answer questions, first one done
• A raccoon guide with a hint that matches the answer key
• An answer key with answers marked in red, plus a short teacher note with what to watch for

How Teachers Use It

Read the teach box and the worked example together, then let students try Part A and Part B. It takes 8 to 10 minutes and prints clearly in black and white. The focus skill is showing that matter is conserved when it changes form, part of TEKS 4.5E: investigate how energy flows and matter cycles through systems and how matter is conserved.

Why It Works

Each sheet uses familiar things like plants, bikes, ice, and food chains, so the big idea is easy to see. Questions are short, mostly circle or one line answers, and the reasoning is on the teacher key. Pair it with the other seven Grade 4 Big Ideas in Science sheets to cover patterns, cause and effect, scale, systems, energy and matter, structure and function, and stability and change.
