Resource 4: Additional reflection activities
Teacher resource for planning or adapting to use with pupils
Are we really two-faced?
Are the two halves of our face exactly the same? Pupils might enjoy an activity where you look at full-face passport photographs that they or you bring.
Stand a small hand mirror down the midline of the face in the photograph so that the reflected half makes one face with the uncovered half. Now do the same to the opposite side. Isn’t it amazing how different the two faces are? That is because our faces are not exactly symmetrical.
Shaking the wrong hand
Try to shake hands with your own image in a large mirror – when you hold out your right hand, it offers you its apparent left hand.
Repeat this, but this time, arrange two mirrors at right angles. Look into the corner and you will see one image of yourself. Offer to shake hands.
What hand does the image in the two mirrors offer this time?
Can you work out why this happens?
Brainstorm uses of mirrors:
- Which devices contain mirrors?
- Where are they useful?
- How could mirrors be useful in a shop to help security?
Experiment with looking at reflections in curved pieces of metal like spoons and kettles.
- What happens to the reflection?
- What patterns can you notice?
Light and dark
Gather together a collection of different shiny materials and objects. Experiment with looking at them:
- in normal classroom light;
- in a ‘black box’ where there is very little light;
- when a torch is shone on them.
Which objects are the shiniest? Can you put them in order of shininess? What happens when you put them in the box? What happens when you shine a torch on them? Can you see any patterns in your observations?
"Kifaa cha 4 cha ""Kufikiria Zaidi"" - Rasilimali ya Mwalimu kwa Mipango au Kubadilisha kwa ajili ya Kutumia na Wanafunzi - Je, Sisi Ni kweli ""Wana-Nyuso Mbili?""" Je, sehemu mbili za uso wetu ni sawa kabisa? Wanafunzi wanaweza kufurahia shughuli ambapo wewe kuangalia full-uso pasipoti picha kwamba wao au wewe kuleta. Weka kioo kidogo cha mkono chini ya mstari wa katikati wa uso katika picha ili nusu iliyoonyeshwa iwe uso mmoja na nusu iliyofunuliwa. Sasa fanya vivyo hivyo kwa upande ule mwingine. Je, si jambo la kushangaza jinsi nyuso hizo mbili zilivyo tofauti? Hiyo ni kwa sababu nyuso zetu si sawa kabisa. Kushikilia mkono usiofaa Jaribu kushikilia mkono na picha yako mwenyewe katika kioo kikubwa <unk> wakati unapoinua mkono wako wa kulia, inakupa mkono wake wa kushoto unaoonekana. Rudia jambo hilo, lakini wakati huu, weka vioo viwili kwa pembe moja. Angalia katika kona na utaona picha moja ya wewe mwenyewe. Kutoa mkono wa mkono. Ni mkono gani ambao picha katika vioo viwili inatoa wakati huu? Je, unaweza kuelewa ni kwa nini jambo hilo hutukia? Brainstorm matumizi ya vioo: - Ni vifaa gani vyenye vioo? - Zina manufaa gani? - Kwa nini vioo vinaweza kuwa na manufaa katika duka ili kusaidia usalama? Jaribu kuchunguza mwangaza katika vipande vya chuma vilivyojipinda kama vile vijiko na mitungi ya maji. - Ni nini kinachotokea kwa mwangaza? - Ni mifumo gani unayoweza kuona? Nuru na giza Kukusanya pamoja mkusanyiko wa vifaa tofauti glossy na vitu. Jaribio na kuangalia yao: - katika taa ya kawaida darasa; - katika <unk>sanduku nyeusi<unk> ambapo kuna mwanga kidogo sana; - wakati tochi ni shining juu yao. Ni vitu gani vinavyong'aa zaidi? Je, unaweza kuziweka kwa utaratibu wa kung'aa? Ni nini kinatokea unapoweka ndani ya sanduku? Ni nini hutokea unapowashambulia kwa taa? Je, unaweza kuona mifumo yoyote katika uchunguzi wako?
