Matter in Motion

Overview

Students begin a Quarter 1 matter and energy journal by developing an initial model of matter. They read a short grade-level science text, connect its explanations to a particle diagram, and write a supported response to the question of the day.

Learning intentions

Students will be able to:

• Explain that matter is made of tiny particles.
• Identify that particles can be represented with a scientific model.
• Integrate information from a science text with a visual particle model.
• Follow a short procedure for observing, modeling, and recording ideas.

Success criteria

• I can define matter as something that has mass and takes up space.
• I can draw and label a model showing that matter is made of particles.
• I can use evidence from a text and diagram to explain my model.
• I can write a complete response to the question of the day.

Curriculum links

• Read and comprehend grade 6–8 science and technical texts independently.
• Integrate quantitative or technical information in words with information shown in a diagram or model.
• Follow a multistep procedure when completing a scientific task.
• Organize scientific ideas clearly with headings, diagrams, and written explanations.

Lesson structure (40 minutes)

1. 0–5 min · Question of the day. Teacher displays the opening question in the question-of-the-day slide and asks, “What do you think particles look like?” Students silently write a prediction in the matter journal page, then share one idea with a partner. Encourage students to distinguish between what they know and what they are imagining.

2. 5–12 min · Build background. Teacher presents the definition of matter and reads the short explanatory text on the matter and particles teaching slides aloud, pausing to define matter, particle, mass, and volume. Students annotate the journal text by underlining the definition of matter and circling one important detail about particles. Students who prefer listening may follow a teacher-read version rather than reading independently.

3. 12–20 min · Model and discuss. Teacher reveals the particle model on the particle diagram slide and models a think-aloud: “This drawing is not a photograph. It is a scientific model that helps us represent something too small to see.” Students compare the words in the text with the diagram and record two details the diagram communicates. Ask: “What does the diagram show well, and what can it not show?”

4. 20–30 min · Create a journal model. Teacher gives step-by-step directions from the particle-model directions slide: draw a container, add several particles, label the particles, and write one sentence explaining what the model represents. Students complete their own model in the matter journal page. Circulate and ask, “What evidence from the text supports your drawing?” Students may revise their initial prediction in a different color.

5. 30–36 min · Prompt and response. Teacher displays the writing prompt on the journal response slide: “What is matter, and what do you think particles look like?” Students write a 4–6 sentence response in the journal page. Require a definition, a description of the model, and one piece of evidence from the reading or diagram. Students may use the sentence frame: “Matter is ____. My model shows ____. I know this because ____.”

6. 36–40 min · Share and exit check. Teacher uses the final discussion prompt on the closing and exit slide and invites two or three students to share. Students complete the bottom-of-page exit check: define matter in their own words and circle their confidence level from 1–4. Collect the journal page or quickly scan responses for misconceptions.

Resources

• the matter and particles slide deck
• the matter journal page
• Science notebooks or binders
• Pencils, colored pencils, and erasers
• Board or document camera
• Optional audio reading of the short science text
• Timer

Assessment

• Listen for accurate use of matter, particle, mass, and volume during partner and class discussion.
• Check models for particles represented as many small units, rather than one continuous piece of matter.
• Review the journal response and exit check for a correct definition, a text- or diagram-based detail, and a clear explanation.

Differentiation

• Provide dyslexia-friendly text with a clear sans-serif font, generous spacing, short lines, bolded key terms, and optional teacher or text-to-speech reading.
• Offer a word bank, labeled example diagram, and sentence frames: “Matter is…,” “Particles are…,” and “My evidence is…”
• Allow students to explain their model orally before writing, or dictate their response to a partner or approved speech-to-text tool.
• Challenge advanced learners to explain two limitations of a particle model and predict how their drawing might change for a solid, liquid, or gas.

Extension

• Students create a second model showing a familiar object, such as water in a bottle, and explain how the model provides evidence that the object is made of particles.
• Students add a “wonder question” to their journal that could be investigated during the next class.
