نصيحة: اقرأ المعلومات الصعبة عن

1. كعب كلاين

تحتوي البكتيريا على عدد قليل من الكائنات الحية (الوزن الخفيف) يبلغ حجمها 0.00001 سم (1 سنتيمتر صغير). لقد أصبحت أفضل من أي وقت مضى وأنا أتقن استخدام المجهر.

2. Ziekten

Bacteriën kunnen allerlei ziekten veroorzaken. Ook besmettelijke ziekten zoals tuberculose, difterie, de pest en cholera.

3. Beschermen

Je kunt je beschermen tegen bacteriën door je goed te wassen (vooral je handen) met zeep en desinfectiegel, zonlicht, inenten en geneesmiddelen die de bacteriën doodmaken (desinfecteren).

Gelukkig zijn de meeste bacteriën goede bacteriën. Wij hebben ze zelfs nodig om gezond te blijven.


Makkelijk   Moeilijk   Onbegrijpelijk

4. Vermenigvuldigen

Bacteriën vermenigvuldigen zich heel snel. Bijvoorbeeld door hete lucht op stilstaand water.

Uit één enkele bacterie kunnen binnen één dag 70 miljoen nieuwe bacteriën ontstaan.

5. 30 seconden regel

Als je 30 seconden lang met zeep en warm water rustig en grondig je handen wast, kun je veel ziekteverwekkende bacteriën van je handen af krijgen.

Tot voor kort was het de 20 seconden regel. Maar 20 seconden blijkt in de praktijk onvoldoende effectief.

Zing in je hoofd een liedje dat 30 seconden duurt. Dat helpt om het lang genoeg te doen.

Kernpunten

Kernpunten om goed te onthouden zijn:

  • Bacteriën zijn onzichtbaar klein
  • Bacteriën zijn organismen
  • Bacteriën kunnen je ziek maken
  • Bacteriën groeien heel snel
  • Bacteriën houden niet van zeep

Primary School Wisdoms

These are the fundamental life lessons and pieces of advice that often get instilled in us during those formative years. They might seem simple, but they lay the groundwork for how we navigate the world.

Here are 7 key wisdoms often learned (or at least introduced) in primary school:

1 - Listen carefully when others are speaking.This develops active listening skills, shows respect, and aids in understanding. It's crucial for effective communication.

2 - Everyone makes mistakes; it's okay to try again. This fosters resilience, encourages learning from errors, and reduces the fear of failure. It highlights the importance of perseverance.

3 - Try your best.This emphasizes the importance of effort and personal growth, regardless of the outcome. It encourages a positive attitude towards challenges.

4 - Treat others how you want to be treated.This is the golden rule, emphasizing empathy, kindness, and respect in all interactions. It's about understanding that our actions have an impact on others.

5 - Be yourself.This fosters self-acceptance, individuality, and the understanding that everyone is unique and valuable in their own way. It discourages trying to fit in at the expense of one's own identity.

6 - Clean up after yourself.This promotes responsibility, organization, and consideration for the shared environment. It's a practical life skill that extends beyond the classroom.

7 - Be kind to everyone. This extends beyond just treating others well; it emphasizes inclusivity, compassion, and understanding towards all individuals, regardless of their differences.

These wisdoms are often conveyed through stories, classroom rules, teacher guidance, and interactions with peers. They form a moral and social compass that helps children navigate their early years and beyond. While we might refine or expand on these ideas as we grow, their core messages often stick with us throughout life.
