Science AA1:Foodweb Diorama

 For my Science AA1 I made a diorama.Its about a food web.I did this with my friend Reyhan.

 A food web is a connected food chain.In the diorama we use toys which is shaped animals like cheetah,giraffe,lion and some trees.Then,we make the food web.We also write facts about the diorama.We also choose what habitat we want to make in the diorama.I choose the African savanna.

The animals in African savanna are moose,zebra,giraffe,lion and cheetah.We can form a food web with these animals. 

In a food web,there are producers,consumers and prey and predator.

The producers is the plants which capture sunlight.The zebra,giraffe and moose eat the plants.Then the cheetah and lion compete the zebra and others for food.

 

 We can also help the environment by:

1. By not littering.
2. Recycle.
3. Crush the plastic bottle first before dumping it to the trashbin.
4. Do not hunt for animal's skin,fur and other animal parts.They might extinct.Don't you want to help or precious animals?
5. Grow plants to reduce carbon dioxide in the air.
6. Reduce the use of harmful gases.
7. Use biodegradable materials.

Fieldtrip to Beth Shalom farm

 The plants

On 13 September,I and my friends in my class and next door class,had a field trip to a farm.There we are doing some activities.We identify monocotyledons and dicotyledons plant.We also learn methods in the reproductive system of plants.Like grafting and air layering.Examples of dicots are:corn and eggplant.Examples of monocots are:garlic.

We are also given lunch.We also plant cassava plant for the AA at school.It is about reproduction in plants.Until now,my cassava plant is growing.I think this fieldtrip is quite fun but at the sametime is a little boring.But i enjoyed it.It is on BSD,serpong.You guys should go there,you will get more knowledge :)

Electric Circuit-Building

 The electric circuit building is fine.But I learned to make new kind of circuits.The electric circuit needs many materials.We also answer the questions from our activity book.
 
 

 wires and light bulb

 batteries

Energy Conversion

In this unit,we learn about energy conversion.There are many types of energy like kinetic energy,sound energy,heat energy and many more.

<-----This is a parachute.The energy conversion is:chemical potential energy and kinetic energy.

Annual Project

Annual Project

The annual project consists of many projects like the Power Point presentation, making a diorama, posters and others.The pictures above show one of my annual projects which is the architectural structure.Each of the groups has different architectural structure because they have different a civilization to work on. Examples are Greece,China and Egypt. My group is Indonesia Civilization, mostly history. We chose Monas (National Monument) as our architectural structure.We had lots of trouble and difficulties in the making, but finally we have finished it.

Reflection (Sci Fair)

Reflection (Sci Fair)

I was not there on that day.But,I was there in the making.These are the pictures with my group in the making.

Separating Mixtures

Separating Mixtures
There are ways to separate mixtures.Here are the ways:
Decanting.

Filtering the mixture of flour and water.

Chemical change

Chemical Change



Chemical change is a change which includes a chemical reaction.There are new materials formed.The examples of chemical change (my experiments in school):

Mixture of plaster of Paris with water.

Burning of paper.

Pollution

Pollution


Pollution
Pollution is a distracting, dangerous and discomfort affection to the ecosystem.There are many pollution such as air, water, soil and others.The cause of air pollution is the carbon dioxide coming out from the vehicles and smoke coming out from the factories.Water pollution is caused by chemical waste from the factories and the water become contaminated and soil pollution is cause by oil and fuel dumping and soil being poisoned by chemicals.To stop pollution we need to:


Air pollution:
Use public transportation rather than our own.


Water pollution:
Don't  throw trashes into the water.


Soil pollution:
Stop the dumping of oil and fuel and also other many substances.
