NASA Kids is an excellent site for "kids" of all ages and provides an abundance of information, images, and interesting things to do on astronomy and ship boats activities questions space sciences. In this questlons, students learn about sources of high-energy radiation and calculate student exposure ship boats activities questions ionizing radiation over the past year.
To design, build, and ship boats activities questions the specifications water displacement and load line for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills. This lesson questioons the second in a three-part series on ships.
The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and activitiss and quesgions it to the design and testing of boats. This series of activities builds on previous simple explorations of floating and sinking see the Science NetLinks lesson Sink It for a related activity and ship boats activities questions students for more in-depth examinations of density and buoyancy.
In addition, students should have some skill at designing and carrying out a simple experiment. They also point out the important relationship between engineering and scientific research. While the students learn that most ships are constructed very similarly�whether they sship schooners or destroyers�they also learn that ships range widely in size and are built from very different materials, with very different tools, and to serve different purposes.
The three lessons in this series are outlined. In Ships 1: Give Me a Tall Ship, student teams develop research and reporting skills as they gather information about a specific type ship boats activities questions xctivities and report it to the class. The class, as a whole, compares and contrasts the different ships, noting similarities and differences among ships from different historical eras ship boats activities questions ships built for different purposes.
Ships 2: What Floats Your Boat? Using actigities information from the ship reports they developed in Ships 1, they note ship boats activities questions different types of ships can carry ship boats activities questions amounts of cargo. They learn that overloading ships has, historically, been a dangerous practice. Students often have the misconception that ships first fill with water and this causes them to sink as opposed to qestions reality that ships sink when they weigh more than the water they displace, whether that weight comes from water flowing into the ship or too much cargo loaded on the ship.
This misconception is further ship boats activities questions in the hands-on activity included in the lesson. Students use what they have learned about ship design along with some additional information on shjp Web about how ships are built to design and build a small model boat, qkestions limited materials. Through these activities, students should learn that every design involves trade-offs and decisions. They may find that their initial design fails and they need to revise and rebuild.
These hands-on activities not only allow students to explore the uses of technology and sip, but they also hone experimental design skills and data collection and analysis skills. In Ships 3: Grand Designs and Great Failures, students apply what they have learned to develop an explanation of why two real-life ships sank the British Titanic and the Swedish Vasa. This application of knowledge to real-life situations demonstrates to students that even good designs can fail the Titanic and that the solution to one problem often leads to another the Vasa.
It also demonstrates how cultural and contextual conditions can affect both engineering plans queations their implementation. Note: The amount of materials needed by each group depends on the ship boats activities questions allowed size of the boat; the materials listed below are for a boat that is 12 inches or less in length. Remind students of the story they read about the sinking of the Titanic: I Survived the Titanic.
Ask the actuvities to consider whether the ship sinking can be described in terms of load lines. Assign students to ship boats activities questions of or whatever works for your particular class size. Tell students that each team will be in charge of designing, building, and testing a boat. Each boat should:. After the boats are built, challenge students to develop a procedure for determining the boats' load lines in fresh and salt water.
Then students should repeat the procedure, adding weight only until they feel the boat has reached a safe load. Using a permanent marker, they should mark the fresh biats load line.
Then they can repeat the procedure using salt water see. This is only a general procedure. Allow students to develop their detailed procedures e. Note: If preferred, you can use the method for procedure development outlined in the Science NetLinks lesson, Actovities It. Remember that the load line should be activitiws a queestions carrying as activitids cargo as possible, but safe for varying weather and water conditions.
After you have approved the procedure, students can determine the load line for their ship boats activities questions in both fresh water and in a tub of salt water 3. Students should find that the boats can carry additional weight in salt ship boats activities questions without sinking due to the greater density of salt water and, therefore, the greater weight displacement of the boats in salt water.
It is important to allow teams enough time so qquestions, if their initial designs are not successful in floating and carrying a load, they have time to adjust their design and repair their boats.
Next, students can determine their boats' water displacement by using the same procedure activjties Archimedes. Using the set up described in the Planning Ahead, set the dishpan on a flat surface and set the plastic shoebox in the middle of the dishpan. Completely fill the shoebox to the very rim with fresh water, making sure not to spill water over into the dishpan.
Students should then float their unloaded boat on the water in ship boats activities questions shoebox and begin loading it carefully and evenly with weights nuts, bolts.
Water will spill over the side into the dishpan. When their load line is reached, they should carefully lift out the boat, then the shoebox. Pour the water in the dishpan into activitles liquid measuring cup. This is the amount of water the boat displaces when fully loaded that is, at the load line.
Remember that water displacement is measured in the weight of water displaced rather than the volume of water displaced. If students are curious about how the water displacement of their boats compares to the ships they researched, use the following approximate conversions:. For example, if the ship they researched displaces 7, tons of water, this is activiies to 7, U. Teams should load their boats with a full cargo at the load line and test them in a tank where another team is creating waves with plastic lids or plates.
Distribute the Ship Specifications student sheet. Each ship boats activities questions should complete this, including naming their boat.
Using an upside down shoebox, teams should mount their boat on top, ship boats activities questions glue or tape the boat's specifications on the. If you prefer, students can be encouraged to decorate ship boats activities questions mounting box for their boat. Each team should describe to the class how they built their boat, how they determined its load line, what load it will carry in fresh and salt water, and what the water displacement is.
To complete the lesson, ask each group to write a song about their ship. This can be in a contemporary format or can shop the format of more traditional seafaring songs such as "A Cheer for Plimsoll" found on the Load Lines page of the National Maritime Activiies websiteor "The Edmund Ship boats activities questions. Assess student understanding with a class discussion, using the following questions as guidelines.
If preferred, you can assign these questions to each group to answer in writing:. Allow groups to try warm versus cold water to test the load lines on the boats.
Most ships are marked with load lines for both salt and fresh water and for warm and cold water loads. Since cold water is denser than warm water, the boats should carry more quesrions in cold water than warm water.
Obviously, you can extend this activity by allowing students to add ballast, sails or other propulsion methods, a rudder, and stabilizers to their boats. They could also consider ship boats activities questions one or two bkats. Other ship types can be modeled such as oil tankers and aircraft carriers. The very different designs of these ships point out the importance of, for example, a deep, heavy keel to keep the deck of an aircraft carrier stable and the wide and long shape of a tanker to distribute the weight of the cargo.
See the Tool. See the Collection. See the Lesson. This container should be at least twice as bots and twice questinos long as the maximum size of the ship boats activities questions. If preferred, you can use one larger, common pool or questios for testing. Shup will need at least one set of a question container e.
