Objective and success criteria

Students will: Earth changes: fast or slow?.

  • I can answer questions on today's skill on my own, without help.
  • I can explain each step and say why it works.
  • I can check my answer and spot a mistake.

Before and after

Needs first: Name the landform from its description

Leads to: Ways to slow wind and water from wearing away land

Materials: Rock samples, Hand lenses, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).

Warm-up · 6 min

  • Quick retrieval from earlier learning (Name the landform from its description). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. Which landform is this: a wide, flat area of land? (plain / volcano / mountain / island) → plainPrompt: Is it high or low? Flat or steep? Is water around it?
  2. Which description matches a hill? (a very high, steep area of land with a peak / a deep, narrow valley with steep rock walls cut by a river / a wide, flat area of land / a rounded rise of land, lower than a mountain) → a rounded rise of land, lower than a mountainPrompt: Picture the landform from above and from the side.
  3. True or false? A plain is a very steep landform. (True / False) → FalsePrompt: Picture each landform: high, low, flat or surrounded by water?

Hook · 6 min

  • Pass round different rocks and ask how each one might have formed.
  • Share the objective: Earth changes: fast or slow?. Read the success criteria together.

I do: model it · 12 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: Is this a fast change or a slow change: a storm washing away part of a beach?
  • Step 1: These changes happen suddenly.
  • Step 2: So the answer is: fast (minutes to days)
  • Answer: fast (minutes to days)
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 12 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. Is this a fast change or a slow change: a cave forming in limestone? (fast (minutes to days) / slow (many years)) → slow (many years)Prompt: Could you watch it happen in one day?
  2. Three of these are slow changes. Which one is NOT? (a flood covering fields / a cave forming in limestone / mountains wearing down / a glacier carving a valley) → a flood covering fieldsPrompt: How long does each change take?

You do: independent practice · 17 min

  • Students work on the student sheet. Circulate and check the first two answers of every student early.
  • Students who finish: write a question of their own for a partner, with the answer.

The 8 questions are on the student sheet below, with answers in the key.

Exit ticket · 7 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. Is this a fast change or a slow change: a cave forming in limestone? (fast (minutes to days) / slow (many years)) → slow (many years)Prompt: Could you watch it happen in one day?
  2. Three of these are slow changes. Which one is NOT? (waves slowly shaping a cliff / a glacier carving a valley / a volcano erupting / a cave forming in limestone) → a volcano eruptingPrompt: How long does each change take?

Watch out for

  • Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
  • Remembering facts without the reason: ask "why?" and "what is the evidence?"

Support and stretch

Support

  • Review first: Name the landform from its description.
  • Use concrete materials: rock samples.
  • Give the first step of each question, or a partly worked example to finish.
  • Pair with a confident partner for the guided practice.

Stretch

  • Move on to: Ways to slow wind and water from wearing away land.
  • Explain a common mistake in writing and how to fix it.
  • Write a word problem that uses today's skill, then solve a partner's.
