Part 3: Language Support and Challenge

Sentence frames and word bank

Frames: I observe __________, but I infer __________. Our independent variable is __________. We measured __________ in __________. Our evidence shows __________. This supports our claim because __________. A fair test keeps __________ the same.

Word bank: observe, infer, natural resource, hazard, safety, fair test, variable, control, evidence, data, measure, unit, trial, pattern, reliable, uncertainty, claim, reasoning, conclusion, improve

Scaffold for support

Complete the prompts: We will test ____________________. We will change ____________________. We will measure ____________________ in ____________________. We will keep the same ____________________, ____________________, and ____________________.

First, we will ____________________. Next, we will ____________________. Then, we will ____________________. Finally, we will ____________________.

Our claim is ____________________. Our evidence is ____________________. This matters because ____________________.

Extension for advanced learners

Explain how repeated trials increase reliability. Identify one source of uncertainty and explain how it could affect your results. Then redesign the investigation for a local farm, lake, forest, or machinery-safety context.

Learning connections

Use precise technical steps and explain how each step follows from the last (CCSS.ELA-LITERACY.RST.6-8.3). Write a claim supported by reasons and evidence, use evidence from data, and include a graph or planned graph to communicate findings (CCSS.ELA-LITERACY.WHST.6-8.1a, WHST.6-8.1b, WHST.6-8.7).
