Plants grow

Do you remember where do plants get their energy from?

Growing baby

Think about how our bodies grow and why choosing healthy food is important.
If you have any question, ask!

The human body

Try to answer the question. How do we grow?

What are Proteins?

Friday, December 14, 2007

Can you guess what is this?

If not. Just ask in class!

Anatomical model of the human body

Can you find any proteins?

FOOD: Protein

Protein are the building blocks of our body. We find protein in our bones, and muscles. We find protein in our hair and nails. There is protein in our brain, and also protein is part of our blood.

Proteins are the building blocks of our bodies. Like the bricks in a house, proteins are small compared to the size of our bodies. Nevertheless, as we grow our bodies add more bone and muscle tissue, and remember, what is bone and muscle made of?
What would you eat if you want to grow big, strong and smart?

You can try this recipe from: http://www.morinu.com/pressbox/AboutSoy.html

Southwestern Tofu WrapMakes 4 wraps

1 ripe medium avocado
6 ounces Mori-Nu Silken Tofu, Extra Firm Lite
1/4 cup minced red onion
Four (10-inch) flour tortillas
2 tablespoons lime juice
4 green lettuce leaves
1 canned chipotle in adobo sauce, finely choppped
1/2 teaspoon ground cumin1 medium tomato, diced

Cut the block of tofu in half; place one half in an air-tight container and store in the refrigerator. Place the remaining half on a stack of paper towels to drain the liquid. Set aside.
Slice the avocado in half the long way to reveal a large pit. Remove the pit, scoop out the flesh and place it in a large bowl; add the onion, lime juice, chipotle and cumin. Mix well with a fork until the avocado is mashed and the mixture is well blended. Set aside.
Slice the tofu into 1/4-inch dice cubes. Add the cubed tofu to avocado mixture; combine gently.
Warm the tortillas in a microwave for ~10 seconds or until soft. Top each tortilla with one lettuce leaf, 1/4 of the guacamole mixture, and 1/4 of the tomatoes. Fold the sides of one tortilla up and towards the center. Fold the bottom and top up to cover the filling, to encase the filling completely, making a neat packet. Repeat with the remaining tortillas. Wrap each one tightly in plastic wrap and refrigerate until ready to serve.

Always ask:

Nicole's question: How can we know what is in our food and where does our food come from?

There are several ways. One is to read the Nutrition Facts label that comes with most of our foods.

Another way of knowing what is in our food is to ask the person who grew it how did he or she did it. Of course, this can be very difficult if you get food from a supermarket. But if you visit your local farmers' market you can ask your local farmer directly!

Try at least once!

Farmers' Markets: Old Oakland
Location of Markets: 9th St. in Downtown Oakland
Days/Times: Fri 8am-2pmYear round/Seasonal: Year round, rain or shine
Public Transportation to Market: BART to Old Oakland Farmers' Market AC Transit to Old Oakland Farmers' Market
Phone: 510.745.7100

Taste the difference.

Hydroelectic Power - How it Works

When we use water to generate electricity we call it hydroelectric power. Remember hydro=water

How can we get electricity from water?

Engineers and scientists use water to generate electricity using dams and turbines. Water flows through the dam almost at free fall speed. There are special turbines at the bottom of the dam that will rotate with the flow of the water producing electricity.

Check out some dams in this pictures:
Hoover Dam. Nevada/Arizona border

United Kingdom

Glen Canyon Dam

This is a picture of the turbines:

The largest hydroelectric plant of the world is the Three Gorges Dam in China:

Animals also build dams. Beavers for example build dams to live in:

Here is a picture of a beaver dam:

Where does our food come from?

Greek dictionary

GRAPH = to draw (paint)
HYDRO = water
CIDE = kill
HOM = person
PHOTO = light
SYNTHESIS = to build
So, what does PHOTO GRAPH mean?

Food and energy

People get energy from their food. But, what happens if you get too many calories and you don't use them?


Remember, the number of calories tells us how much energy is within our foods.
Can you find the number of calories in this food label?

Water contamination

Remember, water is vital for us only if its clean.

Water can get contaminated very easily. Can you find the sources of contamination here?

When the temperature of our body increases, sweat helps us bringing it down. Can you find the origin of sweat in the picture above?
Our normal temperature is 37 degrees.


Remember: Water is H2O

How much water is within our bodies?
Our bodies are almost 80% water. Remember: There is water in our bodies as part of blood, saliva, etc, etc, etc, etc. Can you calculate how much water is within YOUR body?
Remember, it is around 75%

Food Pyramid





Energy: The sun


Our food (3)

Energy comes from our food. And different foods have different quantities of energy. For example,
Compare broccoli and meat:

Energy that we get from our food, is consumed when we do any work. Remember: Energy is the capacity to do any work.
How many calories are we eating?

Look for the Nutrition Facts in your food. Are we getting enough minerals?
