Frog life Cycle

Monday (14/03/2011)

a) Wee Hong’s experience.
• He shared that he and his mother changed the tadpole water twice a day and fed them with little fish flake food. At one point, a tadpole was quiet at the aquarium bottom that he thought it died. I explained 2 reasons: probably sleeping. Secondly, probably resting because frogs are nocturnal like bats.

b) Body Movement
• We jumped around like any water animals. I’d call the names out and they moved accordingly. As I said “freeze”, they has to stop. Example: Guppy, tadpole, tortoise, shark, octopus, starfish, jellyfish, Anaconda and crocodile.

c) About frogs.
• We learnt about its Life Cycle. The spawn eggs consist of babies and they already strated eating plants and microorganisms that got stuck on the spawn. They swim their way out. Some mothers swallow the eggs as protection and release them when the tadpoles hatched. Tadpoles have a long tail and gills which eat plants like algae. After a week, their 2 legs will pop out and their tail become shorter. Finally, they become froglets and their gills change to lungs. Here they start to eat insects and etc. They take about 4 moths to be an adult and would eat insects with their long sticky tongue and bite with their only upper row of teeth.
• They breathe through nose on land and as they go into water, they close their nostrils and absorb Oxygen through their wet skin.
• There are about 5000 types of frogs and tree frogs have nno webbed feet. Courful frogs are poisonous. Hunters use their toxins to hunt. Their croaking sound differ and use to attract mates and to communicate such as giving warnings. They are hunted by birds, snakes, monitor lizards, foxes, people and also by bigger frogs. Chun Kit said he ate frogs before and it was delicious. The kids said….”Yeeeerrrr” and I told the kids to respect peoples’ choices because they eat frogs that are probably bred.
• Their body has got muscles that equivalent to sprig and would jump vey far as far as 2metres.
• Wee Hong quicly went out to get an encyclopaedia to show the class of a poisonous frog.

d) Japan Tsunami.
• My father told me about it. It’s scary. I brought in papers for kids to view and explained briefly that the earthquake had influenced the water balance and caused such a great wave over the land. The objective is to tell kids that water had a great force.
