Hello readers and bloggers.

The challenge: is to build that supports a 300g vehicle

The equipment you need for this

1. Newspaper
2. cello tape
3. Scissors
4. 2 chairs

   1. Spread out 2 chairs so they measure about 1 metre apart.

   2. Roll up 6 of the sheets of newspaper into long rolls.

   3. Tie the string onto the back of the chair or use the cello tape to fix it then go from one chair across to the other. Do this with two pieces of string.

   4. Make large ‘H’ shapes to become the pillars for your bridge. They will hold the string for the suspension. Fix them in place with the tape.

   5. fold the paper to make it

   6. fold the paper in different way
   7. . make the middle of the bridge strong.

WALT: to look at the different types of bacteria.

1. bacteria are everywhere
2. Bacteria are good or bad
3. When bacteria reproduce they are all the same.
4. Bacteria eat through their cell wall.
5. All bacteria are microscopic or tiny.
6. Older Than Dirt (Really!) Bacteria has been on the planet for more than 3.5 billion years old, making them the oldest known life-form on earth.
7. A bacterium can typically move about 100 times its body length in a second. To put that into perspective, a large fish can move only about 10 times its body length in the same time.
8. That yogurt you ate this morning?  That’s made with bacteria. Many snacks like yogurt, cheese, Kimchi, and miso are all made with bacteria.
9. Your body has far more bacterial cells than human cells. They help with processes such as digestion and they defend your body from bad bacteria. Of all the bacteria in the world, less than 1 percent will make you sick.
10. Lined up from end to end, bacteria would stretch out around 10 billion light years. That’s the distance from here to the edge of the universe.

Definition: Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet’s ecosystems.

4 good Bactria name Lactobacillus, Bifidobacteria, Streptococcus, Saccharomyces.

4 bad Bactria name Campylobacter, Clostridium, Listeria, Norovirus.

Bactria lives at soil, rock, oceans and even arctic snow.

Bactria How do they eat many bacteria eat starches and sugars which can be found on more or less all organic matter.

How do they reproduce? by binary fission
