Photosynthesis Song

Here's a very interesting way to learn about photosynthesis. Try it!

Time lapsed seeds growing

Radish seeds Now it is time for you to observe your own seeds. What do you observe?

Yeast Balloon- Respiration produces carbon Dioxide

The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process. While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume. We made a yeast-air balloon during one of our lessons. Here are some pictures captured during our activity. Enjoy!

Reproduction in Plants

Just a quick revision about helping plants grow well. Give it a try! Learn about the different parts of a flower.

Reproduction in Animals

Many of you are really curious about this unit because I've noticed many kept flipping to the pages of this chapter. Well, here are some interesting insights into this topic :

1. Why living things reproduce? All living things will die some day because of old age, illnesses, diseases, accidents or attack by predators. So reproduction in living things helps to ensure their own kind to continue to exist on Earth. What happens if living things can no longer ensure their survival? Yes, they become extinct.

Let's take a look at some of the animals that are already extinct. What is the difference between extinct and endangered?

2. From parents to young A family tree is a good way to show how people who are not our immediate family are related to one another. When living things reproduce, some characteristics or traits of the parents are passed on to the young. So the young inherit these characteristics from their parents. When traits are passed from the parents to their young, that is called heredity. This traits are passed through structures called genes. Let's learn more about genes. This will be great for out trip to the DNA laboratory. What are genes? Let's look at some of the traits that we can see: Some of these traits are

• colour of our eyes, hair and skin
• height
• dimples
• ability to roll the tongue
• attached or detached ear lobes

in animals,

• colour of their fur

in plants.

• colour of the flowers

Asexual Reproduction vs Sexual Reproduction

We've discussed the differences between the two.

Here's a picture of one of my cats Bobo and look at picture when she's a tiny kitten. Can you spot her belly button? Remember we discussed about what umbilical cord is? Take a look.

The Unit of Life

1.The Cell

All living things are made of one or more cells. A cell is the smallest unit of life and all living things begin with a single cell.

Single-celled or unicellular organisms Paramecium is a microscopic unicellular organism that moves using hair-like structures called cilia and flagella. Amoeba is a microscopic unicellular organism that moves using pseudopods(false legs) Bacteria is also a microscopic unicellular organism that comes in various shapes such as spherical, rod-like or spiral and can live in clusters. Also check out how big they are. Yeast are very economically useful organism used in baking and brewery industries. They need food to eat and produces carbon dioxide, which causes dough to 'rise'. Many-celled or multicellular organisms These organisms are made up of more than one cell For Example: Plants, Animals, Fungi such as mushroom

2. Parts of a cell

You have observed an example of an animal cell-the human cheek cell. You have also observed 2 different types of plant cell: the onion cells and Elodea cells. One is photosynthetic because it contains chloroplasts.

3. Producing New cells

Cells increase in number by a process called cell division. Both unicellular and multicellular organisms undergo cell division. Unicellular organisms reproduce either by cell division or budding. In cell division, the nucleus and the cytoplasm of a parent cell divide to form 2 identical daughter cells which then in turn divides further to form more cells.

For example yeast undergo budding.

Notice the parent cell buds and forms another, smaller daughter cell.
