3rd Grade How Refrigerators Changed Our Lives

3rd Grade How Refrigerators Changed Our Lives Worksheet (Science Changes Lives, TEKS 3.4A)

Students learn that cold slows down the tiny germs that spoil food, and how that science led from the ice box to the refrigerator. They number the 4 story steps, then circle answers about food safety and less waste. Simple black and white doodles and big, easy to read text keep it quick and fun.

What's Inside

• Then and now doodles (ice box and refrigerator) with the science behind the change and the STEM helpers involved
• Part A: number the 4 story steps 1 to 4, with one done
• Part B: circle the best answer about how the change helps people
• A friendly squirrel guide and an I can goal
• A visual answer key with answers marked in red, plus a short teacher note and an extend idea

How Teachers Use It

Use it with a science lesson, a STEM day, a career week, or a science center. It takes 6 to 8 minutes and prints clearly in black and white. Each Science Changes Lives sheet follows the same 4 steps: the problem, the science behind it, the invention, and the impact. Students see how scientists and engineers use what they learn to solve real problems, with no long history to read.

Why It Works

Students only number, circle, or write Y or N, so they can finish on their own. Every part has a done for you example. Wrong choices are believable, not silly, so students have to think. Pair it with the other Science Changes Lives sheets to build a full set on how science and STEM careers shape our world.
