Level 1

Alaska Science
Key Element C2

A student who meets the content standard should understand that scientific knowledge is validated by repeated specific experiments that conclude in similar results.

Performance Standard Level 1, Ages 5–7

Students will compare observations and/or repeat observations to check for validity of results.

Sample Assessment Ideas

red rule

Sample Assessment Ideas

  • Students observe unpainted structures made of wood (e.g., sheds, fences); discuss the occurrence of wood shrinkage.

  • Students observe a phenomenon which repeats itself regularly (e.g., dropped ball bounces at a lower height with each successive bounce); compare results with other students for validation.

National Science Education Standards

Scientific investigations involve asking and answering a question and comparing the answer with what scientists already know about the world. (Page 123)

Scientists make the results of their investigations public; they describe the investigations in ways that enable others to repeat the investigations. (Page 123)

Scientists review and ask questions about the results of other scientists’ work. (Page 123)

 

Benchmarks

When a science investigation is done the way it was done before, we expect to get a very similar result. (Page 6)

Science investigations generally work the same way in different places. (Page 6)
