Design and conduct a study using repeated trials and replication.
General Information
Subject Area: Science
Grade: 8
Body of Knowledge: Nature of Science
Idea: Level 3: Strategic Thinking & Complex Reasoning
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.

Just Right Goldilocks’ Café: Temperature & Turbidity:

This is lesson 3 of 3 in the Goldilocks’ Café Just Right unit. This lesson focuses on systematic investigation on getting a cup of coffee to be the “just right” temperature and turbidity level. Students will use both the temperature probe and turbidity sensor and code using ScratchX during their investigation.

Research Project: Sensing Nature:

In this week-long, open-ended activity, students will observe their local environment, devise and pose a testable research question, conduct observations using sensors, and use mathematics skills for quantitative analysis and plotting. To communicate results, students will summarize their findings on a custom poster that explains their work.

Designing a Better Glider - Repetition:

Students are asked to work as an aeronautical engineer, working on the development of a unique glider. The basic design has already been prototyped, but the company is looking at improving the design. Students have been hired to look into changes in the design to produce a glider that can fly farther. They are expected to collect and present evidence to show their design is superior to the original prototype. Throughout the lesson, the importance of repetition in scientific investigations will be emphasized.

Shipwrecked Pirates:

In this lesson, students will take the role of shipwrecked pirates. Working in groups, they will have to use the concepts of force, speed, scatter plots, and literal equations to come up with a way of getting one student to a nearby sister island so that they will both have enough food to survive.

Type: Lesson Plan

STEM Catapult Challenge:

In this lesson, students will design catapults for offense that will be able to shoot down as many objects as possible in a 20-object tower. They will also design a 20-object tower for defense that is least likely to be knocked down by their opponents catapults. As they complete their investigation, they will be designing and implementing two experiments in one. They will identify a problem, make a prediction, collect and analyze data, and draw conclusions. By the end of the lesson, they should be able to differentiate repetition from replication as well.

Ancient Archery: Scientific Method and Engineering:

Students must assist an archaeological research team to determine which material ancient archers likely used to string their bows. Students must design an experiment to test various materials for power, precision, and durability. After the data is collected, they must develop a system to determine which material would have been most desirable for the ancient archers.

This MEA is a multifaceted lesson designed to address both the processes of discovery through scientific investigation and problem-solving through engineering. The full-scale MEA involves the development of a complete experiment and a proper lab report and then an application of the collected data to address the problem-solving requirement of the MEA.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.
