Parachutes slow down the fall of an object by creating more air resistance for the falling object. All objects fall at the same speed, regardless of their mass. But, more air resistance can slow them down. So, as a parachute is made larger, it will have more air resistance and slow down the object more.

Students use the free computer game Pingus to learn how engineers, specifically environmental engineers, use their technical writing skills to give instructions and follow the instructions of others. Students learn to write instructions to express their ideas in clear, organized ways using descriptive, un-ambiguous sentences, as an example of one type of technical writing that important for engineers. The students write instructions enumerating how to beat a game level, which represents surveying that level for environmental problems. As a test of their instructions, students review each others' instructions and offer suggestions for improvement, and then revise their instructions to make them better. Students also see some examples of environmental problems.

Students learn about the mechanical advantage offered by pulleys in an interactive and game-like manner. By virtue of the activity's mechatronic presentation, they learn to study a mechanical system not as a static image, but rather as a dynamic system that is under their control. Using a LEGO® MINDSTORMS® robotics platform and common hardware items, students build a mechanized elevator system. The ability to control different parameters (such as motor power, testing load and pulley arrangement) enables the teacher, as well as the students, to emphasize and reinforce particular aspects/effects of mechanical advantage.

Warming oceans and melting landlocked ice caused by global climate change may result in rising sea levels. This rise in sea level combined with increased intensity and frequency of storms will produce storm surges that flood subways, highways, homes, and more. In this activity, visitors design and test adaptations to prepare for flooding caused by sea level rise.

Through the two lessons and five activities in this unit, students' knowledge of sensors and motors is integrated with programming logic as they perform complex tasks using LEGO MINDSTORMS(TM) NXT robots and software. First, students are introduced to the discipline of engineering and "design" in general terms. Then in five challenge activities, student teams program LEGO robots to travel a maze, go as fast/slow as possible, push another robot, follow a line, and play soccer with other robots. This fifth unit in the series builds on the previous units and reinforces the theme of the human body as a system with sensors performing useful functions, not unlike robots. Through these design challenges, students become familiar with the steps of the engineering design process and come to understand how science, math and engineering including computer programming are used to tackle design challenges and help people solve real problems. PowerPoint® presentations, quizzes and worksheets are provided throughout the unit.

Students learn how two LEGO MINDSTORMS(TM) NXT intelligent bricks can be programmed so that one can remotely control the other. They learn about the components and functionality in the (provided) controller and receiver programs. When its buttons are pressed, the NXT brick assigned as the remote control device uses the controller program to send Bluetooth® messages. When the NXT taskbot/brick assigned as the receiver receives certain Bluetooth messages, it moves, as specified by the receiver program. Students examine how the programs and devices work in tandem, gaining skills as they play "robot soccer." As the concluding activity in this unit, this activity provides a deeper dimension of understanding programming logic compared to previous activities in this unit and introduces the relatively new and growing concept of wireless communication. A PowerPoint® presentation, pre/post quizzes and a worksheet are provided.

In this lesson, students will be introduced to the importance of sleep and its effects on the body. Students will complete a pre-test activity, which tests their prior knowledge of sleep. A class discussion on sleep allows the teacher to identify and clarify any misconceptions that students may have before beginning the sleep exploration. While the sleep journal activity is in progress, students should view the Scientastic- Are You Sleeping video. In addition to the sleep journal, students will be recording their relative sleepiness levels on three different days during the exploration. Students will maintain their sleep journals for 10 days, after which they will use the data collected to calculate their average sleep times. Afterwards, students will compare their results with to their classmates. This will be used to generate a "How Tired Are You Today?" graph. This activity can be used to show students how their sleepiness levels can change throughout the day and how they may not be consistent everyday of the week.

Students are introduced to brainstorming and the design process in problem solving as it relates to engineering. They perform an activity to develop and understand problem solving with an emphasis on learning from history. Using only paper, straws, tape and paper clips, they create structures that can support the weight of at least one textbook. In their first attempts to build the structures, they build whatever comes to mind. For the second trial, they examine examples of successful buildings from history and try again.

In this activity, students investigate the effect that thrust has on rocket flight. Students will make two paper rockets that they can launch themselves by blowing through a straw. These "strawkets" will differ in diameter, such that students will understand that a rocket with a smaller exit nozzle will provide a larger thrust. Students have the opportunity to compare the distances traveled by their two strawkets after predicting where they will land. Since each student will have a slightly different rocket and launching technique, they will observe which factors contribute to a strawket's thrust and performance.
