Project 4: Questions
1. If a railway is 900 tracks long and half of those tracks are powered rails, how many powered rails are there?
2. If the other half of those tracks in question #1 are detector rails, how many detector rails are there?
3. If you can go 15 tracks in 1 second, how many tracks can you go in 6 seconds?
4. If there are 4,000 powered rails and 4,000 detector rails, how many tracks in all?
5. If you can go 300 tracks in 20 seconds, how many tracks can you go in 2 minutes?
6. If a castle is 200 tracks away from your house and your mine cart can travel 10 tracks in one second, how long will it take to get to the castle?
Project 4: How to Build a Railroad Track
Layer 1: Building the Railroad - Place an iron block at the edge of your town and then place a powered rail in front of the block in the direction that you want it
to go. Then place a detector rail in front of the powered rail. Repeat the process of the rails until you're happy with the distance. After that, place another iron block at the end of the power rail.
Layer 2: The Transportation - To finish, place a mine cart on the rail, and when you move inside the cart, the mine cart will move along the track.

Biosphere 2 is a facility in Arizona where scientists study the earth and its living systems. Today we'll be building our own biosphere in Minecraft.
Begin by finding a large piece of land that you will be able to develop. This land does not need to be flat. In fact, your biosphere will be more interesting with a few hills and valleys. To build your biosphere you will need one door and lots of glass blocks.
Layer 1: Building the Outside Walls - Place glass blocks in a square or a rectangle around the area in which you want to build your biosphere. Don't worry about the ground being level. Just place the blocks around the perimeter or the outside line of the land. On one side, leave a space to place a door. Go ahead and put a door in the space you just provided.
Note: The biosphere is similar to a pyramid. As we build the walls up, we will also be building inward one block every time we add a layer to the wall.
Layers 2: Completion - The Walls Continued - Working around the previous layer, place glass blocks directly on top of the wall, then put another block on the side that is facing inward. Then destroy the first block. This creates a step. Continue on building steps all the way around the inside of the previous layer, and repeat the process going up until the hole is completely closed up.
Design the Inside of the Biosphere: Start by building a waterfall. Build it by digging a hole in a rock formation and put a bucket of water in the hole.
After you make the waterfall, dig a space for the waterfall to end and put buckets of water in the big hole.
Next, you should grow a forest. Plant trees by planting tree saplings in a certain area of the biosphere. Find flowers too and replant them in the forest.
The Circle of Life - Lure in animals by using wheat for sheep and cows, seeds for chickens, and carrots for pigs.
Project 2: Answers
1. Since 5 by 5 blocks is the same way of saying 5 x 5, how many blocks are there in total? 25
2. A 3 by 3 hole is the same as saying 3 x 3. How many blocks make up the hole? 9
3. If there is a 3 by 3 square of torches, how many torches are there in all? 9
4. If there were six glass panes on one wall, how many glass panes would there be if there were four walls? 24
5. Since the base of the roof is a 7 by 7 square which is also
7 x 7, how many blocks in all? 49
6. If our tower is 32 feet tall and we reduced the height by 19 feet, how tall would our tower then be? 13
7. If 8 Minecrafters each built 9 towers, how many towers would there be in all? 72
