Task 1
Construct a table for a classroom collection: 5 mainly wooden objects, 9 mainly plastic objects and 3 mainly metal objects. State a clear rule for counting an object made from more than one material.

Tables, Column Graphs and Scientific Models worksheet
Use eight independent written and practical reasoning tasks. An adult checks the actual work.
Open practiceEight independent homework tasks
Use paper for your measurements, tables, drawings and explanations. An adult checks the actual work. Use teacher-provided sources where a device or field observation is unavailable.
Task 2
Draw a column graph for distance travelled on three surfaces: felt 20 cm, paper 40 cm and tile 80 cm. Use a title, labels, zero baseline and equal 10 cm intervals. Write one supported comparison.
Task 3
Draw a fictional neighbourhood map with a school, creek and water tank. Use a key to mark the two water sources and a north arrow. Write two location statements that your drawing supports.
Task 4
Make a food-chain token model using 12 plant tokens and 5 consumers, each needing 2 tokens. Feed as many consumers as possible, giving each its full two tokens. Repeat with 8 plant tokens. Record how many consumers can be fully fed in each round and one limit of the model.
Task 5
Draw a magnet on the right and a paperclip on the left. Add a labelled arrow showing magnetic force on the paperclip and explain where the arrow starts and why it points that way.
Task 6
Draw a box sliding left across a surface. Add a friction arrow acting on the box. Explain one feature your drawing shows and one feature it does not measure.
Task 7
A checked table records sand 10 cm, felt 30 cm and smooth card 60 cm. A draft graph puts felt at 50 cm. Construct a corrected graph and explain how you checked every column.
Task 8
Choose one model you made in this homework: map, food-chain simulation or force diagram. Add two labels that improve its scientific meaning and write “shows” and “does not show” statements.
Answers and adult review checks
Task 1
Answer: A labelled Material | Number of objects table has wood 5, plastic 9, metal 3. A consistent main-material rule avoids unexplained double counting.
Inspect the actual table, all three values, clear headings and an applicable mixed-material rule.
Task 2
Answer: Columns reach 20, 40 and 80 cm on the same scale. Tile travel is 60 cm farther than felt in this test.
Inspect the actual plotted heights, equal scale, units and numerical comparison. Do not accept ranking alone.
Task 3
Answer: Layouts vary. The creek and tank are clearly located as sources with a symbol key; two relative-location statements agree with the drawing.
Inspect the constructed map, sources, north arrow and both statements. No visit to water is required.
Task 4
Answer: All five consumers can be fed in the first round with two tokens left; four can be fed in the second. Real feeding relationships are more complex.
Inspect the actual token arrangement or drawing, two-row results and an accurate limitation; a token model does not predict exact real populations.
Task 5
Answer: The arrow starts on the paperclip and points right towards the attracting magnet.
Inspect the receiving object, arrow direction and label; reject an arrow that shows only the magnet position without the force on the clip.
Task 6
Answer: The friction arrow begins on the box and points right. It shows force direction but does not measure the force size or show every force.
Inspect the actual drawing and the distinction between direction and unmeasured size; no force calculation is needed.
Task 7
Answer: Correct heights are 10, 30 and 60 cm on a labelled equal-step scale; compare each category and height with the checked table.
Inspect all three columns, not only the corrected felt column, and a clear audit explanation.
Task 8
Answer: Accept labels relevant to the chosen model and a specific relationship with a defensible limit, such as locations without exact distance scale.
Inspect the revised original model and two meaningful labels; generic statements such as “it is good” are insufficient.
