Interpreting data from tables and graphs

Working scientifically

CCSS NGSS.SEP 4CCSS NGSS.SEP 5England: KS4 Working scientifically

Objective and success criteria

Students will: Interpreting data from tables and graphs.

  • 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: Reading tables and line graphs; Repeat readings, means and anomalies

Leads to: Analyse climate data: COâ‚‚ records and temperature trends

Materials: Simple equipment for a fair test, Results table template, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).

Warm-up · 4 min

  • Quick retrieval from earlier learning (Reading tables and line graphs; Repeat readings, means and anomalies). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. A group measured the time for a ball to roll down a ramp three times: 22, 25 and 23 s. What is the mean? Give your answer to 1 decimal place. → 23.3 sPrompt: Add the three readings.
  2. Distance from lamp (cm) → Bubbles from pondweed per minute 10 → 43 20 → 40 30 → 37 40 → 34 10 → 31 What happens to “Bubbles from pondweed per minute” as “Distance from lamp (cm)” increases? (it decreases / it stays the same / it increases / it goes up then down) → it decreasesPrompt: Read down the second column. Are the numbers getting bigger or smaller?
  3. A group measured a pulse rate after exercise three times: 100, 102 and 98 bpm. What is the mean? Give your answer to 1 decimal place. → 100 bpmPrompt: Add the three readings.

Hook · 3 min

  • Show a simple experiment with one thing changed and ask what makes it a fair test.
  • Share the objective: Interpreting data from tables and graphs. Read the success criteria together.

I do: model it · 7 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: Study: Cooling coffee. Time (min) → Temperature (°C) 0 → 83 5 → 73 10 → 63 15 → 53 20 → 43 Estimate the value at 17.5, assuming the pattern between neighbouring points is a straight line.
  • Step 1: (53 + 43) Ă· 2 = 48
  • Step 2: So the answer is: 48
  • Answer: 48
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 6 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. Study: Light and pondweed. Distance from lamp (cm) → Bubbles per minute 10 → 43 20 → 37 30 → 31 40 → 25 50 → 19 Estimate the value at 35, assuming the pattern between neighbouring points is a straight line. → 28Prompt: 35 lies halfway between 30 and 40.
  2. Study: Light and pondweed. Distance from lamp (cm) → Bubbles per minute 10 → 43 20 → 37 30 → 31 40 → 25 50 → 19 How does “Bubbles per minute” change as “Distance from lamp (cm)” increases? (It decreases steadily. / It increases steadily. / It increases to a maximum, then decreases. / It stays about the same.) → It decreases steadily.Prompt: Read the second column from top to bottom.

You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.

Exit ticket · 3 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. Study: Enzyme activity. Temperature (°C) → Reaction rate (units/min) 10 → 2 20 → 20 30 → 38 40 → 56 50 → 38 60 → 20 At which value of “Temperature (°C)” was the lowest value recorded? (10 / 20 / 40 / 50) → 10Prompt: Find the smallest number in the second column.
  2. Study: Light and pondweed. Distance from lamp (cm) → Bubbles per minute 10 → 49 20 → 43 30 → 37 40 → 31 50 → 25 Estimate the value at 25, assuming the pattern between neighbouring points is a straight line. → 40Prompt: 25 lies halfway between 20 and 30.

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: Reading tables and line graphs.
  • Use concrete materials: simple equipment for a fair test.
  • 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: Analyse climate data: COâ‚‚ records and temperature trends.
  • 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.
