Repeated Trials and the Mean

Repeated Trials and the Mean Worksheet (Grade 6 Science, TEKS 6.1F)

Show grade 6 students why one test is not enough and how to find the mean of repeated trials. A paper airplane experiment makes the idea simple and fun.

What's Inside

• A short reading on repeated trials, reliable data, and the mean
• A lab notebook page with one fully worked example in two steps
• Activity 1: Students add the trials and divide by 3 to find the mean for three designs
• Activity 2: Two questions about the results
• A visual answer key with answers marked in red

How Teachers Use It

Use it before students run their own repeated trials, as math-in-science practice, or as review. The numbers are kept small so students focus on the idea. Every term is taught on the page, so no prior knowledge is needed. The sheet takes about 10 minutes, works for independent work, partners, or homework, and prints clearly in black and white.

This worksheet is part of the Reading in Science series for grade 6. It supports TEKS 6.1F: construct appropriate tables, graphs, maps, and charts using repeated trials and means to organize data. Pair it with the other sheets in the series to build a full unit on scientific and engineering practices, one skill at a time.

Why It Works

Each sheet teaches one or two new terms in plain words first, then asks students to use only what the page taught. Activities stay at the sort, circle, and match level, so students build confidence while the answer key gives teachers the reasoning they need.
