Simple Science Experiments

Overview

Grade: 1–7 (Adaptable by age)
Time: 30 minutes
Class size: 2 students
Unit: Exploring the Wonders of Science (Lesson 4 of 10)
Alberta Curriculum Program of Studies:

• Science, K-7
• Science 1-3: Understanding Context for Science and Technology (ST1-1, ST1-2)
• Science 4-7: Skills and Processes (SP4-1, SP4-2)
• Cross-curricular opportunities with Language Arts: Writing and Reporting

---

Learning Objectives

Students will be able to (linked to Alberta Science Curricular Outcomes):

• Understand and apply the scientific method to conduct a simple experiment (Grades 1-3: SP1-2, Grades 4-7: SP4-1).
• Record observations and results systematically (Science K-3: ST1-1; Science 4-7: SP4-2).
• Communicate findings clearly through a written or illustrated report (Language Arts K-7 Writing Curriculum).

I can statements:

• I can follow steps of the scientific method to complete an experiment.
• I can observe carefully and write down what I see.
• I can share what I learned by writing or drawing a report.

Success Criteria

Students demonstrate the ability to:

• Identify and state the question/hypothesis.
• Plan and carry out the experiment following steps with guidance.
• Record observations on a dyslexia-friendly recording template.
• Share results in a clear, simple written or drawn report.

---

Materials Needed

• Experiment kit (can be simple household items such as water, salt, sugar, spoons, cups, paper towels)
• Scientific method worksheet template (dyslexia-friendly: large font, clear boxes, simple language)
• Writing or drawing materials (pencils, crayons, markers)
• Timer or clock (to measure time intervals)

---

Vocabulary

• Hypothesis
• Experiment
• Observation
• Result
• Conclusion

Lesson Activities (30 minutes)

1. Introduction and Review (5 minutes)

• Briefly review the scientific method with the students using simple language: Question → Hypothesis → Test → Observe → Results → Conclusion.
• Use a visual chart or poster with symbols for each step, focusing on clear, dyslexia-friendly fonts and spacing.
• Connect to the previous lessons about science and wonder to build excitement about “doing” science.

2. Demonstration of the Experiment (5 minutes)

• Example experiment: "What dissolves faster—salt or sugar in water?"
  • Question: Which dissolves faster?
  • Hypothesis: Salt will dissolve faster.
• Demonstrate the setup and explain each step aloud, modelling correct recording.
• Emphasize measuring time and carefully observing changes.

3. Student Experiment (10 minutes)

• Each student conducts the experiment individually or collaboratively with direct teacher support.
• Students use their templates to write or draw their observations (time, appearance, any changes).
• Teacher scaffolds the process by prompting each scientific method step, helping with vocabulary and comprehension.
• Use multi-sensory support: talk through observations, allow drawing if writing is hard.

4. Sharing and Report Writing (7 minutes)

• Students share their results orally first to build confidence.
• Complete the report on the provided dyslexia-friendly template combining words/drawings.
• Teacher reviews with positive, constructive feedback.
• Students articulate a simple conclusion: Did the results match the hypothesis?

5. Extension (3 minutes)

• Challenge students to brainstorm a new experiment based on today’s findings.
• Prompt questions like: "What else could we test with water? What changes if we use cold water?"
• This extension can be homework or used in the next lesson.

Differentiation Strategies

• For emerging learners or students with learning difficulties:
  • Use guided prompts and one-on-one support.
  • Provide the scientific method template with sentence starters and picture cues.
  • Allow verbal responses or drawing instead of writing.
• For advanced learners:
  • Encourage designing the next experiment in more detail (variables, controls).
  • Include additional measurements (e.g., temperature, stirring speed).
  • Facilitate a short discussion on why hypotheses might be right or wrong.

---

Assessment

• Formative assessment during the experiment through observation and questioning: Does the student follow steps logically?
• Review of completed scientific method template: completeness, accuracy of observations, clarity of conclusion.
• Informal oral sharing to assess communication of findings.

---

Dyslexia-Friendly Reading & Writing Support

• Use large, clear sans-serif fonts (Arial, Comic Sans) with 1.5 spacing.
• Highlight key vocabulary with colour coding (e.g., “Hypothesis” in blue).
• Provide audio or video instructions summarizing steps.
• Use bullet points and numbered steps for ease of reading.
• Include plenty of visuals (icons, pictures) alongside text.

---

Teacher Reflection & Notes

• Consider adapting experiment complexity based on age and prior knowledge: Grades 1-3 focus on very simple experiments and observations; Grades 4-7 include controlled variables and hypothesis testing in more detail.
• Emphasize inquiry and curiosity to build scientific attitudes.
• Provide positive reinforcement and celebrate accurate observations even if experiments “don’t work.”
• Use paired learning to foster collaboration and discussion.
