Lesson 1: Controlled experiments and data

Science Lesson

Learn: A controlled experiment plans one independent variable, measures a dependent variable and attempts to keep other relevant conditions consistent. Replication and uncertainty matter. Fictional data are useful for mathematics practice but cannot be described as observed results.

Science Practice: 10 Assignments

1. Write a testable question about a toy car’s movement.
2. Identify one independent variable.
3. Identify one dependent variable.
4. List three controlled conditions.
5. For fictional data 4,6,8,10,12 calculate the mean.
6. Find the range of those data.
7. Explain why a sample of one may be unreliable.
8. Describe a possible confounder.
9. Write a claim supported by only the given fictional data.
10. Advanced: draft a replication plan and explain limits of causal inference.

Observe and Explain

Separate observations from hypotheses and illustrations from measured results. Never invent experimental data. Use safe materials and adult guidance where needed.

Advanced Science Extension

Form a measurable question about this lesson, describe a fair comparison and identify at least one limitation. This challenge is available at any age when prerequisites are mastered.

Grade 6 | Five-Day Science Investigation Extension

Five original science lessons with direct explanation, written practice, and a formative independent check. This extension is not a whole-year textbook.

Day 1: Variables and Fair Tests

Download Day 1 fillable PDF (print or save)

A testable question identifies a manipulated independent variable and a measured dependent variable. For a toy car experiment, change ramp height while keeping the same car, surface, starting position, and release method. Do not use powered or hazardous equipment.

• 1. Ask a testable ramp-and-distance question.
• 2. Name the independent variable.
• 3. Name the dependent variable.
• 4. Name two controlled conditions.

Record any observational data with dates and units. Distinguish a hypothesis from a verified result.

Day 2: Repeated Measurements

Download Day 2 fillable PDF (print or save)

Measurements vary because of surfaces, release technique, and instrument precision. Repeat trials and record every result, including unexpected ones. A mean is the sum divided by the number of measurements.

• 1. Find mean of 4, 6, 8, 10, 12.
• 2. Find the range of those numbers.
• 3. Why repeat trials?
• 4. Why report units?

Record any observational data with dates and units. Distinguish a hypothesis from a verified result.

Day 3: Tables and Graphs

Download Day 3 fillable PDF (print or save)

A table should identify independent-variable settings, trial numbers, and distance measured. A graph uses an even scale and properly named axes. If numbers are invented for practice, label them simulated data.

• 1. List three headings for a trial table.
• 2. Which axis usually shows ramp height?
• 3. Which axis shows distance traveled?
• 4. Can simulated results prove a real experiment happened?

Record any observational data with dates and units. Distinguish a hypothesis from a verified result.

Day 4: Confounders and Claims

Download Day 4 fillable PDF (print or save)

A confounding variable changes alongside the variable of interest and makes a conclusion less reliable. If one group uses a different toy car, that difference may affect distance independent of ramp height.

• 1. Name one confounder.
• 2. How can you reduce it?
• 3. Can one trial prove causation?
• 4. What should a valid claim refer to?

Record any observational data with dates and units. Distinguish a hypothesis from a verified result.

Day 5: Independent Check

Download Day 5 fillable PDF (print or save)

A learner tests three ramp heights using the same car, surface, and release. Distances are recorded in cm over repeated trials.

• 1. Name the independent variable.
• 2. Name the dependent variable.
• 3. Why keep the car identical?
• 4. Mean distance for fictional trials 12, 15, 18 cm?

Record any observational data with dates and units. Distinguish a hypothesis from a verified result.

Spiral Review and Advanced Application

Revisit two earlier ideas with fresh examples. Design one safe observational or model-based inquiry, including its variables, intended measurements, and limitations.

Grade 6 Science Unit 1: Expanded Student Textbook

Read this original five-day science student textbook before completing the corresponding daily workbook PDFs. The teacher answer guide is separate. This text is Unit 1, not the complete year-long textbook.

Student Textbook Day 1: Variables and Fair Tests

Read and Understand

The independent variable is changed intentionally, the dependent variable is measured and controlled factors reduce alternative explanations.

Worked Example and Guided Practice

Design a toy-car ramp experiment with one changed factor.

After reading, complete the Day 1 downloadable workbook questions independently.

Student Textbook Day 2: Repeated Measurements

Read and Understand

Repeated trials show variation. Mean equals total divided by count, while range is maximum minus minimum.

Worked Example and Guided Practice

For 28, 31 and 30 centimeters calculate an approximate mean of 29.7 and range of 3.

After reading, complete the Day 2 downloadable workbook questions independently.

Student Textbook Day 3: Tables and Graphs

Read and Understand

Tables need labels and units; scatter plots may display paired measurements. A trend need not prove cause.

Worked Example and Guided Practice

Plot hypothetical ramp height and distance pairs, then identify one limitation.

After reading, complete the Day 3 downloadable workbook questions independently.

Student Textbook Day 4: Confounders and Claims

Read and Understand

A confounder changes alongside the proposed cause. A test using different cars and surfaces cannot isolate ramp height.

Worked Example and Guided Practice

Name two uncontrolled factors and suggest how to remove them.

After reading, complete the Day 4 downloadable workbook questions independently.

Student Textbook Day 5: Independent Check

Read and Understand

Use a fresh table to identify variables, compute a mean and write an evidence-based conclusion.

Worked Example and Guided Practice

Explain what additional trials would improve confidence in the result.

After reading, complete the Day 5 downloadable workbook questions independently.

Unit Review

Review all five lessons with new examples. Record evidence and measurements accurately, distinguish observations from interpretations, and discuss errors with a teacher.
