Lesson Preparation for the Teacher:
Photos designed in the form of a blockposter in the link above are removed. You can divide the children into groups if you want, or you can have them done individually.
Students are asked to put together the puzzle-shaped photos distributed. Students may then be asked the following guiding questions:
1-What does this tool look like?
2-Why does he have a sail?
3-Does only sea vehicles have sails?
4- Gasoline is necessary for the movement of cars and planes. Some trains run on coal. So what do you think drives this vehicle?
The answers given by the students to the above questions that establish the school life connection and include their preliminary knowledge.
answers are heard by the teacher. And it goes to the problem state:
“Deniz’s teacher enters the classroom with a photograph that looks like a sailing vehicle in his hand. The teacher says that the photograph is a “Black Sailboat”, how it moves, its features and tournaments. It states that our school will also participate in the land sailing tournament and the fastest land sailing boat will represent the school. Do you think Deniz will be able to build the fastest “Black Sailboat”?
1- To learn about land sailing
2- Helping Deniz to design the fastest land sailboat.
TO EXPLORE THE SUBJECT BETTER, WE WILL DO 3 FUN STUDY IN THIS SECTION:
1- First of all, students are asked to do research and gather brief information about land sailing. Using the “Popplet” web2.0 tool together, a mind map is prepared with the information you have learned:
Note: Popplet Usage Video:
You can prepare it in different ways and with different information.
2-A wind rose is made to observe the force of the wind with the students.

3-“LANDSAIL DRAMA STUDY”
Game play: First, the students are asked to form a circle. And one person in the middle becomes a midwife. The students are given the names of the materials of the land sailboat, respectively: Sail-Mast-Wheel-Carbine-Seat…. A name is also given to the midwife. When the teacher says to change the sails, the sails are changed, and when the teacher says to change the masts, the masts are changed. But when he says LANDSAIL, everyone has to change places. The midwife tries to find a place for herself. The person who cannot find a place becomes a midwife. The game continues in this way.
The aim of the drama work is to make people comprehend the materials of the land sailer…
Note: The game can be more fun with large groups.

At this stage, students are briefly informed about the land sailing boat:
What is Land Sailing?
Racing tricycles over wide and flat pieces of land is called land sailing. In sailboats moved in the direction of the wind, the angle of the sail is changed to give direction to the vehicles. Land sailing first emerged in the 1950s. Land sailing, which has turned into a racing sport after the 1950s, is one of the extreme sports that is very popular especially in the United States and Europe.
Land sailing tournaments and races are held in many countries. One of the most popular of the international tournaments is the week-long European Championship. The World Land Sailing Championship, which is held every four years, is also one of the most popular tournaments.
Although it has similar points with normal sailing, land sailing is based on the wind. Wind has much more thrust than water. In this way, sailboats can move much faster than on the water.
How to do Land Sailing?
In this sport, which is made with three-wheeled sailboats of different sizes, vehicles are classified differently according to their sizes. Sailboats in the same category compete with each other. Sailboats are divided into 2nd, 3rd, 5th, 7th and 8th Class. At the same time, mini sailboats consisting of standard class and smaller vehicles compete separately. The most frequently used class in these races is the 3rd class.
Necessary Materials for Land Sailing
The sailing materials required for land sailing are usually purchased separately and combined to make them ready for the sport.
The first equipment required for land sailing is a sail. Models produced in different sizes and features are in various classes. Pilots choose sails according to which class they will be in. Sails from 2 meters to 8 meters are produced.
The masts that help the sails to stay stable are produced with durable materials. Poles produced with materials such as fiberglass, carbon and ultra carbon are designed in various thicknesses and lengths. In addition to being durable, the sailboats are very light thanks to their maximum weight of 1 kilogram.
It is necessary to use different sizes of wheels in sailboat models, which are divided into early and late periods. Wheels are chosen from multi-toothed and heavy or flatter and lighter models according to sailing classes.
Carabiners are used as attachments in many extreme sports. High quality carabiners are used together with ropes and screws for joining main parts such as sails, seats and masts.
When is Land Sailing Done?
For land sailing races, periods with strong winds are definitely preferred. Beach edges, dry lakes in desert lands, even airstrips are suitable for races. Spring months, when the wind is strong as a season, is the most suitable season for land sailing. Races can be held in the regions where the wind is seen in the summer season. Very cold weather and snow-covered areas are not suitable for this sport. Generally, from March to November, there are favorable weather conditions for doing this sport.
Best Land Sailing Routes in the World
Land sailing tournaments, which are widely held especially in Europe, are accompanied by uniquely beautiful beaches.
The following informative videos can also be watched:
PUSH AND PULL issues can also be briefly mentioned:
If the direction of the force is towards us, it is attraction.
If the direction of the force is ahead of us, it is repulsion.
Examples of Push and Pull Forces:
*Wind shakes tree branches
*The wind blows the kite
*The wind carries the sailboat
*The wind turns the windmill
“Answers questions about images” with Blockposter work. The learning outcome is “Answers questions about what they listen/watch with the informative videos they watch.” The outcome is “Writes meaningful and regular sentences” in popplet web2.0 application. His achievement is “Fills the forms according to the instructions” in the crosswordlabs web2.0 tool application. A plan suitable for gains is implemented.
Information is exchanged on which geometric objects to choose for the design. The designed prototype is first measured with non-standard measurement units and compared. Then, using a ruler, drawing the line segment whose length is given, forming triangles, squares, rectangles and determining the diagonals are done.
The student realizes that he can solve problems by modeling. Uses problem solving steps. Develops the ability to use technology in the right direction while researching and using web 2.0 tools.
LIFE SCIENCE AND SCIENCE INTEGRATION:
“What is wind energy? Where to use? Have information about “Push and Pull Force”.
An Annex-1 form is distributed to the students. Students start making design drawings to help Deniz.
Each student draws a design. Describes the features of the design in prototype drawing and explains how the design will work.
The necessary materials for their design are provided by the parents and the teacher.
All students will be given 3 days for the design and at the end of this period, everyone will be
It is stated that he will explain the features of his own design in the class. with available materials
Ask students to turn their solutions into products. The design phase begins.
4.1. SKETCH DRAWING OF THE DESIGN
**At this stage, students will be guided while drawing the design.
**You can watch the Black Sailboat design drawing presentations from the link below:
4.2. DESIGN TIME
**Start and check the design you will prepare.
4.3 SHARE YOUR PRODUCT
**Tell your friends about the construction stages and materials of the design you have prepared by making a presentation.
**After the presentations are over, everyone compares their own design with the designs of other students. Thus, they have the opportunity to evaluate and improve their designs. The teacher uses supportive statements for students to improve their products. After sharing, students are asked what they can do to improve their designs. Students can refine their designs if they need to.
**Products made in the school entrance hall are exhibited and offered to other students:
In order to measure what the students have learned about the “BLACK SAIL”, the following puzzle is solved using the CROSSWORDLABS web2.0 tool.
After all the sharing is done, the design evaluation form is distributed and the students
It is ensured that they evaluate their product objectively.
5.1. ASSESS YOUR PRODUCT AND THINK BETTER
