Western leopard toad

Last week-end Caleb and I went on a Junior Rangers Camp at the Silvermine reserve. The leaders had felt that the Junior Rangers had worked hard all year and deserved a nice week-end out. Hannah and Sheth joined us in the day but went to sleep at granny's house at night with Greg, their dad.

We arrived at the camp late on Friday evening in the pouring rain. It was dark and cold. Supper was being served so Caleb ate straight away. It was a brown soup - vegetarian. The meals for the week-end were terrible! It was white rolls with all the meals. For lunch each day it was a white roll with margarine. Yuk! ...and palony! Double yuk! There was no lettuce or tomato to go with the rolls, or any other vegetables for that matter. It can not get worse than that. Breakfast was Cornflakes or Nutrifix. Caleb enjoys Cornflakes as we never have it at home. What I have learnt is that I will have to provide food for Caleb on the next camp.

This is a River Click Frog
found on one of the hikes
The rest of the camp was great! We did two fairly long walks, and one serious hike! We did an evening walk which Greg joined us on. We walked to the Clovelly Golf Club. This is where we were hoping to see the migrating Western Leopard Toad. Well we did! We found the males in the ponds and found two females walking across the greens of the golf course. We also sat and listened to their calls. It was fantastic. I think Caleb and Sheth enjoyed it more than anyone else. This comes from the fact that kids between 14 and 17 are more interested in the opposite sex of the human race than in the mating of the Western Leopard Toad.

Facts about the Western Leopard Toad:
  • Their name is Western Leopard Toad or August Toad
  • They move in the rain
  • They move up to 5 km
  • They are nocturnal so move at night
  • They move on a waxing moon
  • The male has a darker throat than the female
  • The female's throat is almost a lemon colour
  • The male is smaller than the female
  • If the female toad has a predominantly triangular shape, then she still has eggs in her
  • She has 1000 to 2000 eggs in her
  • The male toad jumps on the female's back and gets into the Amplexus position. He has nuptual pads on his hand that help him hold on to her
  • If a female gets into the water without a male on her back she will be marked and drowned
  • The female lays strings of eggs which are black. The male then puts sperm over the eggs to fertilise them
  • Their eggs take about 2 weeks to turn into tadpoles
  • It takes about 3 to 4 months to grow into a toadlets
  • Baby toads are called toadlets
  • The toads burrow into the ground, to sleep during the day. They share their burrows with other toads
  • Toads walk and hop
  • Frogs can only hop
  • Every Western Leopard Toad has its own special pattern on its back
  • The Clovelly Golf Club has Koi fish in their ponds. These Koi fish are eating the Toads eggs, tadpoles and toadlets
  • The Western Leopard Toad is an endangered species

South African curriculum

In Waldorf, in each grade, we study certain things. So in grade 1 it is Fairy Tales. Grade 2 Nature Stories and The Saints. Grade 3 Old Testament, clothing, fibre and housing etc.

As we live in South Africa we will study our local tribes and history instead of Native American. When the children are older we will study Native Americans. I think it is very important to learn about one's own country - to understand our roots.

I have bought a South African curriculum called Little Footprints. The age suggestion is 4 to 8. I think it is way too academic for that age and use it, spread it out over grade 2 and 3. I do not use it as a stand alone curriculum, but use it as local geography and history blocks. The story books are fantastic.
For grade 4, 5 and 6 I bought Footprints on our Land. It is a very good curriculum. The draw back is that it is very expensive for what you get. The books are all "home" printed in black and white. The covers are a very light weight cardboard, that pick up stains and dirt easily. The teachers guide is also black and white. The cover has a plastic sheet to keep it clean. It is not much more expensive for the producers to have laminated the front cover instead. The binding is also inferior, so you have to be very careful when using your teachers manual. For maybe R20 more the producers could have used the metal ring binding and laminated the front cover.

But after all that I would still buy the Footprints on our Land curriculum for the content alone. The curriculum is a literature based curriculum. It consists of 24 books. I do the first 8 books in grade 4, the next 8 books in grade 5 and the last 8 books in grade 6.

I will be buying the Footprints into the 21 st Century for grade 7 and 8.

Grade 6 & 7 curriculum: Natural science / Geology & Astronomy

Geology and Astronomy
by Charles Kovacs
Cost is about R100 to R150 depending on the exchange rate. Book Depository does not charge for shipping. Loot shipping is free for orders over R230 so even if the exchange rate is not doing too well, it might still be cheaper to buy from Book Depository if you are getting a single book.

The first part of this book describes the different kinds of rocks, soil and mountains found on our planet, and explores how they came into being. This section deals with the depths of the earth, and the long ages of time.

In contrast, the second part examines the heights of our universe, in the movement of the sun, moon, and stars. There bodies give us our sense of day, month, and year.

Throughout, Kovacs links the phenomena he describes with human experience, how they affect people in different parts of the world.

I bought this book as a zoology study for my kids. It is written in story form and therefore I read it straight to my kids. They absolutely loved it. It is much more than just a zoology book.

We did two blocks, part one was a four week block and part two a three week block, using this book. If you are interested, contact me and I will give you my lesson plans for this.
