# Science learner cards · Days 11–20

Your teacher may read every card. You may use drawing, writing, pointing, speech, touchable pieces, signing or AAC; a partner may move pieces exactly as you direct. **Never look directly at the Sun.** A paper model or invented record is labelled as such; do not write “I observed” unless you truly made a safe observation.

## Shared fictional shadow record for practice

These numbers were **invented to practise reading a record**. They are not measurements from a real place or date. Imagine one fixed paper pole, the same measuring unit, and three notes made on one imagined day:

| Time | Shadow length in paper units |
| --- | ---: |
| 9:00 | 4 |
| 12:00 | 2 |
| 15:00 | 5 |

## Day 11 · Model of a turning Earth

Use a Sun card and an Earth disc with one dot. Show when the dot faces the Sun card and when it faces away. Say one thing this **model** can show and one thing it cannot tell about today's sky. **Home:** two paper circles work; no outdoor task is needed.

## Day 12 · Record one safe shadow

With your teacher and an approved fixed object, mark where its shadow ends **on the ground**. Add date, time, object and a simple length unit. Do not look toward the Sun. If your class stays indoors, use the practice record and label it invented. **Home:** use the invented record; no one needs to arrange outdoor observation.

## Day 13 · Compare two records

Use two safe class shadow notes from the **same object** if available; otherwise use two times from the shared fictional record. Which was earlier? How did the measured length differ? Label your evidence “class observation” or “invented practice”. **Home:** choose any two rows of the shared record.

## Day 14 · Sort the kind of statement

Sort these: **A** “A ground mark was measured at 9:00”; **B** “A paper Earth was turned”; **C** “I think the mark will differ later.” Label each as observation report, model action or prediction. What detail would make A a stronger record? **Home:** tell or point to the three categories.

## Day 15 · New record check

Keep this card closed until your teacher asks. This is a **different invented practice record**, using one imagined fixed peg and one paper unit: **8:30 = 6 units; 11:30 = 3 units**. Put times in order. Which recorded length is shorter? What does this pair **not** prove about every day? Say whether these were real class observations or invented practice. **Home after the check:** create your own labelled fictional two-row record.

## Day 16 · Is that comparison fair?

A tall paper pole has a longer drawn shadow than a short paper pencil. Someone says, “The time must have changed.” Give another possible reason. Plan a better comparison that changes time but keeps the object and measuring unit the same. **Home:** use paper strips or words, not actual Sun observation.

## Day 17 · A question about shade

Imagine a bench and two **drawn** shadow outlines at different labelled times. Write or say a question a park helper could check at a real site. What could the drawing **not** prove about safety or every day? **Home:** draw two fictional outlines, not a real park or home layout.

## Day 18 · What seems to move?

Turn the paper Earth dot beside a fixed Sun card. Make three small *model* pictures. Say “appears” when explaining what a person on Earth might notice. What real observation would you need to make separately? **Home:** paper pieces only.

## Day 19 · A careful message

A fictional park helper asks, “Will this bench **always** have shade at 12:00?” Use the **invented** shared record to write/say one thing it shows and one thing it does not show. Replace “always” with a better question to investigate. **Home:** dictate the two lines to anyone, without describing a real park.

## Day 20 · Evidence or model?

Keep this card closed until your teacher asks. New **invented check note A** says one fixed cone's shadow measured **3 paper units at 10:00** and **4 units at 14:00** on an imagined day. New **model note B** says a paper Earth disc was turned beside a Sun card. Which note is an invented observation-style record, and which is a model action? Make one comparison from note A. What safe next observation would test whether the change happens another day? **Home after the check:** explain the difference between an observation note and model action using different examples.
