If this instruction was interesting to you, then leave a small review in the comments. Draw the body of water around and you will have a beautiful bright drawing. The submarine is ready! Optionally, you can add an environment for the submarine. On the other side of the boat, draw two elements of different shapes connected to each other.ĭraw two identical elements on the tail of the boat using curved lines.ĭraw the same small circles on the front of the boat and on the porthole. With the help of several curved lines draw the periscope on the boat’s hull. Designate the front and add an element at the top.ĭraw one vertical line and use a curved line to add a small element at the top.In the middle of the boat, draw two even circles of different diameters. This information can help us better understand when and how the ocean currents are changing.Determine the size and location of your drawing and draw the body in the shape of an oval. The information they collect will help scientists find the answers to these questions-and more!įor example, the NASA mission SMAP-short for Soil Moisture Active Passive-has an instrument that measures the salinity on the surface of the sea. NASA spacecraft are collecting information about ocean temperature and salinity all the time. How are these changes in the ocean's surface temperature and saltiness-or salinity-affecting the ocean currents? How is the melting and heating affecting the average sea level? What would happen if the ocean became too warm and the ice did not form?Īs Earth gets warmer, less ice forms in the Arctic each winter and more ice melts in the summer. Without it, the equator would be way too hot and the northern and southern parts of the planet might be frozen all the time. ![]() This ocean motion is called the "great ocean conveyor belt." The movement of water on this conveyor belt makes Earth a nice place to live.

That is why it is easier to float in the ocean than in a fresh-water swimming pool or lake.ĭoes that mean that fresh river water would float on top of salty ocean water? It all depends on the temperature. Salty water is "thicker" or denser than fresh water. If you have tasted the ocean, you know it is very salty. The rules of the game are how ocean currents work in real life, too. Keep your eye out for the key to unlock the treasure! With these tools, you can make your little submarine go anywhere to get the key to the treasure chest. Walls that you can use to block currents. ![]() In your current management toolbox, you have these tools:Ī sideways current tool that you can use to send, or bend, the current to the right or left. Where do you want to go? You want to get the key to the treasure chest full of gold! In this game, you are in a submarine and you need to fix the currents to take you where you want to go. Play Go With the Flow to learn about ocean currents-and to unlock the hidden treasure! ![]()
