Arthropoda

Dear readers.
We have been doing insects for the last couple of days as well as reptiles.

In insects you get two types of metamorphosis: Hemimetobola(3stages) and Holomatobola(more stages). All insects can be classified under Athropoda.This will include Insecta(insects), Arachnida(spiders and scorpions) and Myriapoda(moths and butterflies). Coleopreta is all your beetles and Diptera is the mosquito's and flies.Hemiptera is the bugs and Cicadas is "sonbesies". The weirdest thing I have heard in a long time is that sand tics are actually known as sand tampons...Yes,have a laugh I know I did!

We also learn't the differences between centipedes and millipedes:

       Centipede:

• Poisonous
• Venom glands and claws
• Fast in nature

Millipede:

• Herbivore
• Non venomous and no claws
• slow in nature

The difference between a moth and a butterfly:
Moth:

• Hold their wings open when in landing position
• Feathered antennas

Butterfly:

• Close their wings when in landing position so it looks like one wing
• They have antennas with swollen tips

With this topic I realized how important insects are to the environment and the ecology. They maintain a balance in nature, they practice some form of waste disposal and the diseases they carry helps improve mans technology.

I found out that the Nile crocodile is the only reptile that looks after its young when they are born.Terrapins live in freshwater, tortoise lives in freshwater and a turtle lives in saltwater. All pythons are non-venomous and the nag adder is the only adder that does not give live birth it lays eggs. There are two types of cobra: s cobra and a true cobra. The difference is that the true cobras are the ones that spit,the rest of the characteristics are that they are both neuro-toxic and they have fixed fangs.The vine snake  is the only snake in S.A that does not have an anti-venom.

We also got our own cruiser and we went to the koppie where we looked at the scenery and discussed the grass and trees we see.Of course we had to have problems with it when we drove to the caravan park! It did not want to start and so it took a man close by to  look at it but when he got in and stated it, it worked...Very embarrassing but we survived.
We are going to welcome our parents today for a parents weekend and we will be doing a role play to show them what we have done so far.

See you next time!
