This  is one exam question which Ying came back saying the teacher told her she was wrong:

The shape of a shadow is the same as the shape of the object. (True/False)

And my teaching:

So, even my girl’s teacher deduct her exam mark, I am still gonna tell my girls, the answer is “False”. Teacher is wrong.

Lesson plan to introduce science topics on Animals, especially for children going to primary 2 next year.

Day 1 : Animals

Day 2 : Animals Life Cycle

Day 3 : Adaptations in Animals

Day 4 : Hibernation and Migration

This video teaches Hibernation and Migration in Animals. And do you know, there is a different between Sleeping and Hibernation? Check it out.

This video gives a good introduction to adaptation in animals.

The definition given for “Adaptation” = The features in animals in which help them to survive in their habitats.

This video gives a brief walk through for Life Cycles of birds, frogs, butterflies and mosquitoes.

This video introduces the different type of animal habitat: Aerial, Aquatic, Terrestrial, Polar and Arboreal; as well as different eating habits: Carnivores, Herbivores, Omnivores (do you know these words come from Latin? 🙂 ).

mm.. they learn new English vocab as well.

I am going through the chapter of Light Energy in this book with my girls. I find the topics covered are more … mm… how to say ‘全面‘, ‘all rounded’ in this book.

In their school textbook, it teaches what is light source, and focus more on the formation shadows due to “light gets block by object”. But I like what this book teaches: the key of light energy is light travels in straight line.

And shadow is formed, when the light, which travels in straight line, is blocked.

Also, there are a few more sub-topic covered in this book which I like:

– we can see things because things reflect light into our eyes. And a good example to explain Moon is not a light source, but it reflects light from the Sun. (I go throw the below question with my girls and they are able to comprehend why we can see the Moon though it’s not a light source; how the light actually travels from the Sun to the Moon and then to the Earth)

– the explanation of transparent, translucent and opaque materials by the mean of light passing through materials.

light0006

– how to change the size of the shadow (my girls’ favorite question)

light0002

 

– the different of shadows at different time in a day

May be some of these will be covered in higher primary classes. Just sharing here. I like how this book organizes the content for this chapter Light Energy.
