Steps, Events and Scientific Ideas

A 40-minute Grade 2 lesson on describing the connection between historical events, scientific ideas or steps in a procedure.

Steps, Events and Scientific Ideas is a free 40-minute Grade 2 English lesson plan for Common Core standard RI.2.3 — explain how a series of events or steps in a text connect. It is timed across 5 sections, gives the exact wording to use where the wording carries the meaning, names 3 misconceptions with the teaching move that addresses each, and ends with an exit ticket and a printable worksheet with its answer key.

RI.2.3

Describe the connection between a series of historical events, scientific ideas or concepts, or steps in technical procedures in a text.

Objective

Students will be able to describe how steps or events in a text connect, using words such as first, then, because and so.

Students are successful when they can

  • Puts the stages of a process in the right order: magma rises, lava comes out, lava cools.
  • Explains a connection with "because" or "so": "The lava cools, so it turns into hard rock."
  • Finds the time and cause words in a text: first, next, then, because, so.

What you need

  • Text "How a Volcano Grows" on chart paper (in the Teach section)
  • Four step cards from the text, cut up
  • A connection chain: arrows labeled "then" and "so"
  • The printable practice sheet linked at the end of this plan

The lesson

Warm-up — what comes next?

5 min
  1. Show three mixed-up steps for brushing teeth: rinse, put toothpaste on, brush. Ask the class to order them.
  2. Ask: "Why does the toothpaste go on before brushing?" Fish for "because you need it to clean your teeth."
  3. Say that steps connect in two ways: one comes after the other (then) and one causes the next (so).

Teach — then and so

13 min
  1. Read the text aloud: "How a Volcano Grows. Deep under the ground, it is so hot that rock melts. This melted rock is called magma. Magma is lighter than the rock around it, so it rises up. When it reaches the top, it pours out as lava. Then the lava cools and hardens into rock. Each time this happens, a new layer is added, so the volcano grows taller."
  2. Circle the order words: When, Then, Each time. Circle the cause word "so" each time it appears — three times. Each "so" means one thing made the next happen.
  3. Lay out the four step cards in order: rock melts into magma -> magma rises -> lava pours out -> lava cools into rock. Draw arrows between them.
  4. Label each arrow "then" or "so." Ask: "Why does magma rise?" (Because it is lighter.) That is a "so" connection: it is lighter, so it rises.
  5. Ask the big connection question: "Why does the volcano grow taller?" Fish for: "because every time lava cools, a new layer of rock is added."
  6. Model saying the whole chain in one breath: "Rock melts, so magma forms. It is lighter, so it rises. It pours out as lava, then cools into rock, so the volcano grows."
“Ask about every step: did it just come next, or did it make the next thing happen? "Then" for next, "so" for made it happen.”

Guided practice — order and connect

12 min
  1. Give pairs five cut-up step cards on how paper is recycled: "Paper is sorted." "It is mixed with water to make pulp." "Ink and staples are taken out." "The pulp is pressed and dried." "It is cut into new sheets."
  2. Pairs order the cards and then explain one connection: "The pulp is pressed and dried, so it becomes flat and hard like paper."
  3. Ask: "Could you cut it into sheets before it was dry? Why not?" Fish for "it would fall apart."
  4. Pairs read their chain aloud to another pair, using "then" and "so."
“Read your chain aloud. Does each step make sense after the one before?”

Independent practice

8 min
  1. Students complete the printable. One sheet asks them to number the steps of a process, such as how a volcano is built or a lifeboat is launched; the other asks how one event or idea in a text leads to another.
  2. Remind them to read all the steps before numbering any.

Close

2 min
  1. Ask: "Why does the volcano get taller?" Take a "because" answer from one child.

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Orders steps by where they appear on the worksheet, not by what has to happen first.

Why: They expect the text to give the answer in order, and do not yet reason about what must come before what.

Fix: Ask about each pair of cards: "Could this happen before that one?" "Can lava cool before it comes out?" Physical sense decides.

Says the steps only follow each other: "The magma rises, then lava comes out" and never gives a cause.

Why: "Then" is the connection word they know best; cause-and-effect is new and harder to see.

Fix: Ask "Why did that happen?" after each step and give the stem "It happened because..." Circle "so" in the text as a cause clue.

Explains a cause backwards: "The volcano grows taller, so the lava cools."

Why: They know the two ideas are linked but not which way round; the sentence sounds fine to them.

Fix: Act it out with layers of paper: add a layer, then the pile gets taller. Ask which action made the other happen.

If they are not there yet

  • Use three step cards with pictures instead of five word cards.
  • Give arrows already labeled "then" to place between the cards before adding any "so."
  • Read the step cards aloud and let the child order them by pointing.

If they finish early

  • Find a step that could be missed out and explain what would go wrong without it.
  • Write a short explanation of the volcano chain from memory, using "because" twice and "so" twice.
  • Compare the volcano text with an earthquake text and describe one way both are about pressure building up.

Exit ticket

Finish: "Magma is lighter than the rock around it, so ___." Then write what happens to lava when it cools.

What to look for: "so it rises up" and "it turns into hard rock." Getting the second but not the first: they can recall facts but not use "so" as a cause signal. Reversed cause ("so the rock is heavy"): practice which-made-which with an action.

Questions about Steps, Events and Scientific Ideas

How long does the Steps, Events and Scientific Ideas lesson take?

40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.

Which standard does Steps, Events and Scientific Ideas teach?

CCSS.ELA-LITERACY.RI.2.3 — RI.2.3, Reading: Informational Text for Grade 2: “Describe the connection between a series of historical events, scientific ideas or concepts, or steps in technical procedures in a text.” In plain terms, explain how a series of events or steps in a text connect.

What do I need to teach this lesson?

Text "How a Volcano Grows" on chart paper (in the Teach section), four step cards from the text, cut up, a connection chain: arrows labeled "then" and "so" and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.

What mistakes should I expect in this lesson?

Three, each a reasoning error rather than carelessness: orders steps by where they appear on the worksheet, not by what has to happen first; says the steps only follow each other: "The magma rises, then lava comes out" and never gives a cause and explains a cause backwards: "The volcano grows taller, so the lava cools.". The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.

How do I know whether the lesson worked?

The exit ticket asks: “Finish: "Magma is lighter than the rock around it, so ___." Then write what happens to lava when it cools.” "so it rises up" and "it turns into hard rock." Getting the second but not the first: they can recall facts but not use "so" as a cause signal. Reversed cause ("so the rock is heavy"): practice which-made-which with an action. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.

Is there a worksheet to go with Steps, Events and Scientific Ideas?

Yes — 1 printable RI.2.3 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.

Is Steps, Events and Scientific Ideas free to use?

Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on October 8, 2026. Please do not resell it or republish it as your own.
