NATURAL SCIENCE: WASTE pages 88 - 89

Hi kids!!!

In Natural Science we are learning many things about Matter but today we are going to review what we do with the things we don't want and throw away.

We call WASTE to all those things we don't want and throw away: our rubbish. For example: an orange peel, a piece of paper, a used napkin or an old toy.

Last year we learnt many things about these in our school. Do you remember "Somos Naturaleza y dejamos huella"? So this is going to be very easy to you but it's important that we review.

It's inevitable to produce waste and there are many different types of waste but we are going to focus on four types of waste:

1. Organic waste that comes from plants and animals. Examples: a fish bone, a potatoe peel, leaves that fell from trees, etc. This waste is BIODEGRADABLE this means that some living things decompose them. 

2. Recyclable waste is that waste that can be used to make new objects. Examples: newspapers and magazines, cans, glass, etc

3. Non-recyclable waste is that waste that can't be used away. Examples: nappies from babies, batteries, plastic, etc. This waste is more dangerous because sometimes it pollutes the land and water.

4. E-waste is that waste that comes from electronic devices. Examples: an old mobile phone, computers, television sets, etc. This waste is also dangerous because some objects contain toxic substances and we have to take this waste to special places. 

What is really important is the three R's:

REDUCE (don't use too much)

REUSE (use them more than once) 

RECYCLE (use the appropriate container)

Now I'd like you to read in your book pages 88 - 89 and do exercise 3.

Here I leave you two songs about this that I hope you like them. Please, listen to them
