General Information

Subject Area: Science
Grade: 7
Body of Knowledge: Nature of Science
Idea: Level 2: Basic Application of Skills & Concepts
Big Idea: The Practice of Science -

A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation.

B: The processes of science frequently do not correspond to the traditional portrayal of "the scientific method."

C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge.

D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Whirligig – The Importance of Repetition and Replication in Experiments

Students write a procedure and conduct an investigation that helps them to differentiate replication from repetition. Students drop the whirligig 3-5 times and record how long it takes to fall to the ground.

Repetition and Replication Made Easy

This is a simple hands-on activity which will help students understand the difference between repetition and replication. It is designed to be science notebook friendly.

The Real Thing?

This is a hands-on (write it, read it, do it) activity to help students master the standard

The learning objectives of this lesson are that the students will demonstrate that replication is the ability to make an exact copy, explain the importance of writing and following precise directions and differentiate replication by others and repetition (multiple trials) and its importance in science. There is an engaging activity, PowerPoint, YouTube video, and much more to help the students understand and know the difference between replication and repetition.

Survival Journal Part Three: Surviving the Epidemic: Planting Tomatoes

This is a detailed lesson based on the germination of seeds, science vocabulary of plants, diseases, and insect infestations with tomato plants. Tomatoes grow nutrients that the human body needs to survive. It is a companion lesson to: Survival Journal Parts 1 and 2 available on CPALMS.

How far or fast can you roll a Tennis ball? Repetition requires the experiment to be repeated at least three times and replication requires the experiment to be conducted by another researcher. Repetition and replication ensures that experiments and experimental results are valid.
How Many Hoops Can You Make? Students create their own examples using basketball to differentiate between repetition and replication.

Name Description
Electronics May Confuse a Bird's "Compass"

This informational text resource is intended to support reading in the content area. Scientists are finally able to support the hypothesis that electromagnetic radiation from human electronic equipment can confuse a bird's sense of direction; the radiation impacts the orientation necessary for birds' migration. When shielded by an aluminum screen (a Faraday cage), this interference is eliminated and birds can orient themselves properly.
