The Captain Siyanse GUIDE SAFETY INSTRUCTIONS 2 WARNING Not suitable for children under 3 years of age, as the kit includes small parts that may pose a choking hazard. Designed for children aged 5 and up. Parental supervision required!
Do not swallow any of the kit components. Do not place the kit or its components near an open ame or any heat source. Hey, Captain Siyanse!
Heres a challenging new mission for you! You need to build a wind-
powered boat using the principles of oating objects discovered in ancient times!
Lets build a wind-powered boat!

What buoyancy is and why boats oat What inuences the ability of objects to oat How to use a compass How to build a wind-powered boat 4 Compass A compass is a navigational instrument for determining direction of travel relative to the Earths magnetic poles. It consists of a magnetized pointer that is free to align itself with the Earths magnetic eld. When people in the past rst learned how to make magnetic compasses, they discovered that when a magnetized bit of iron was oated in water, it automatically pointed north. Sailors then began to use compasses to navigate, or nd their way, at sea. This made travelling more ecient and safer. Now lets practice using a compass. Take a look at the dial. You will see four letters;
they stand for the cardinal directions. Place the compass so that the letter N is on the top and read around the dial clockwise. 5 N north E east S south W west South magnetic pole The red end of the arrow always points to the north. Take your compass and nd where north is. You can turn yourself around and d note the direction the compass points. Now lets try to nd directions other than north. South is the easiest - you just need to walk s the opposite way the compass is o pointing. To go east, you need to go to the right of the direction in which the compass points, and to go west you need to go to the left of the direction in which the compass points. W N S E North magnetic pole EARTHS MAGNETIC FIELD How will you control your wind-powered boat?
Wireless remote control is used in many aspects of our lives, like TV remote control. This wireless remote controlled wind-powered boat uses radio waves to transmit signals; it has four wireless channels that can make the boat move forward and backward, and turn left and right. 6 Precautions:
P Please build your wind-powered boat with your parents it may be dangerous to make it alone. Children p under 6 years of age are advised to assemble under adult supervision. Please unpack the package carefully to avoid losing small parts. If any small parts are lost, the boat may not work correctly. Please read the instructions carefully and follow every step. If ca you dont understand any of the yo instructions, please ask your parents in or teacher for help. o Note: You will need a total of 5 AA batteries three for the boat and 5 two for the remote control. Batteries tw not included. nn ot included. Put on your Captain Siyanse hat and lets get started!

Q&A After the boat is assembled, why doesnt it move?
1. You need to use the remote control (hold down the patch button on the remote control), and your hands must not touch the remote control antenna during remote control. 2. Check whether the switch on the battery box is turned on and if the battery is low. 3. Check whether the wires are connected properly and if the connection might be loose. Consider the environment in which the boat is being used:
You will need a calm water surface, the boat cannot sail in strong wind or rain, the circuit board is not waterproof, and the chip on the circuit board will be damaged if it gets wet. How far away from the remote control is the boat?
The maximum working distance of the remote control is 25 meters, and the maximum distance during remote control operations should not exceed 25 meters. Between 25 and 30 meters, the boats movements may not be predictable. If the maximum remote control distance is exceeded, the boat will not be able to return home. 15 Can multiple remote-controlled boats be controlled separately?
Remote control boats on the same frequency cannot be used together, as they will interfere with each other. Operating The Boat A great place to try out your boat is the bathtub. Fill your bathub halfway, place your boat in the water and make sure it oats. Adjust your boat to be sure it is oating evenly on the water. Flip the power switch on top of the battery box. Boat Notes:
16 Dont submerge the boat. Water can damage the circuitry and the boat may not function. Dont touch the remote control antenna while operating the unit. Dont try to control two boats at once, as they are operating on the same radio frequency. distance, the remote control may not work. Stay within 25 meters of your boat while operating it; beyond this Using your thumb, depress one of the four silver tabs on the remote control. Which direction does your boat move? Try all four and experiment with operating your boat. What happens when you press one tab on one side of the remote and one tab on the other?
Every great seafaring vessel has a name. Pick one that you like, write it on a note card and tape it to the top of the battery box. S.S. Siyanse Voyager, anyone?
Why and How Boats Float Your boat is oating on the water. We can say that it is buoyant. Buoyancy is the ability of something to oat on top of a liquid. It has to do with two characteristics: density and displacement. Density Density is how heavy something is relative to how much space it takes up. For example, an empty bottle and a bottle full of sand take up the same amount of space. But the bottle lled with sand is much heavier than the empty one. If we put it in water, it will sink. The empty bottle will oat. So we can say that the bottle containing sand is much more dense than the empty bottle. 1 Displacement The second thing that inuences buoyancy was rst discovered by an ancient Greek mathematician called Archimedes. He noticed that every time something is put in water, it has to make room for itself by pushing the water aside as it enters. So he gured out that if the weight of the object being placed in the water is less that the weight of the water displaced, the object will oat. This displacement is known as the Archimedes principle. For example, if an object like an empty bottle is lighter than the amount of water it displaces, then the object oats. This tends to happen with less dense objects. If an object like the bottle with sand is heavier than the amount of water it displaces (if its really dense), then it sinks. How do ships oat on water?
You may wonder why a ship, which seems to be so heavy and dense, You may wonder why a ship, which seems to be so heavy and dense, doesnt sink. doesnt sink. A heavy ship becomes buoyant thanks to its design. How is this A heavy ship becomes buoyant thanks to its design. How is this possible? First, it is hollow inside, so it is not as dense as you might possible? First, it is hollow inside, so it is not as dense as you might think. And second, the bottom of the ship is also designed to displace think. And second, the bottom of the ship is also designed to displace a lot of water. These engineering designs make the ship lighter than a lot of water. These engineering designs make the ship lighter than the amount of water it displaces so it can oat. the amount of water it displaces so it can oat. 1 Scientists and Engineers all over the world work to make our lives Scientists and Engineers all over the world work to make our lives easier.
