Scientific Practices Mystery Pixel Art, Part 1

Use scientific and engineering practices to build a mystery laboratory picture. Part 1 focuses on questions, investigations, measurement, and data. Questions missed on the first try return later in Investigation Review.

Questions and variables

Question 1

Investigation Briefing

Need help? The Investigation Briefing explains the science and engineering ideas used in this activity. Open any section for helpful background and examples.

Questions, variables, and problems

Independent variable: the factor a scientist changes. Dependent variable: the result that is measured. A good science question asks how one may affect the other. A hypothesis is a testable prediction that connects the variables.

In engineering, first state the problem clearly. Then offer a possible solution by developing an object, tool, process, or system.

Think: What is changed? What is measured? What must the design do?

Investigations, measurement, and design

In an observational investigation, scientists watch, measure, and record without deliberately changing the system. In an experimental investigation, they change a factor and measure the response. They identify variables, constants, and controls when those parts are appropriate.

Scientists compare methods to decide which can collect more accurate data. They use appropriate tools or technology and record measurements in metric units. Engineers also use science ideas to design, build, and/or test objects, tools, processes, or systems.

Think: Is the method fair? Is the tool a good match? Is the measurement recorded with a metric unit?

Organizing and understanding data

Tables and graphs can organize data so patterns are easier to see. Scientists identify a pattern, explain what it may mean, and evaluate whether every point follows it. They also consider limits in the data, such as a small number of trials.

Scientists compare findings from different groups and discuss similarities and differences. Engineers use test data to evaluate and improve a design so it better meets the criteria.

Think: What pattern is visible? Are there exceptions or limits? How can the data improve the design?

About this activity

This single HTML file runs entirely in the browser. It does not require a login, collect student names, or send answers to a server.

Students get one attempt in the main round. If they miss a question, it comes back later in Investigation Review with a targeted clue and a link to the related Investigation Briefing section. Questions and reference text use sixth-grade-friendly wording while keeping the full scientific meaning.

Content focus: asking questions, identifying variables, planning investigations, choosing tools and measurements, organizing data, recognizing patterns, and using data to improve a design.

Accessibility features include keyboard navigation, visible focus indicators, screen-reader updates, non-color status cues, strong color contrast, reduced-motion support, a keyboard-accessible modal Investigation Briefing with expandable sections, and a clearly labeled sound control. Sounds play only after a student action and are never required to understand feedback.
