This STEM challenge can be used during an air unit. Students work together in groups to create a parachute for a lego person. Students are able to find ways to best maximize air resistance. The students need to find the best way to increase the time that the lego person stays in the air when dropped from the second floor to the first floor.

Students learn that dams do not last forever. Similar to other human-made structures, such as roads and bridges, dams require regular maintenance and have a finite lifespan. Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years. The engineers with Splash Engineering have an ethical obligation to remind Thirsty County of the maintenance and lifespan concerns associated with its dam.

This Force and motion Roller Coaster activity was done with my 5th grade class and they enjoyed it. It took longer than a normal science period but was a fun end of the year activity to help students stay engaged to their learning. Graphic created by Ashley Moses Author: Ashley Moses Date Added: 06/14/2021Creative Commons Attribution  Language: English  

In a rocket, propellant escapes from the bottom of the rocket. In this balloon investigation, air escapes from the end of the balloon. The rocket lifts off due to the escaping propellant. The balloon moves due to the escaping air. Like a rocket, the balloon travels in the opposite direction of the propellant.

Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.

Student teams creatively construct mobiles using hangers and assorted materials and objects while exploring the principles of balance and center of mass. They build complex, free-hanging structures by balancing pieces with different lengths, weights, shapes and sizes.

When an object is placed in water, there are two primary forces acting on it. Buoyancy is the force exerted on an object that is wholly or partly immersed in a fluid. The force of gravity is a downward force and buoyancy is an upward force. The gravitational force is determined by the object's weight, and the buoyancy force is determined by the weight of the water that is displaced by the object. If an object weighs less than the amount of water it displaces, it floats; if it weighs more, it sinks.

A bungee jump involves jumping from a tall structure while connected to a large elastic cord. Design a bungee jump that is "safe" for a hard-boiled egg. Create a safety egg harness and connect it to a rubber band, which is your the "bungee cord." Finally, attach your bungee cord to a force sensor to measures the forces that push or pull your egg.

A zip line is a way to glide from one point to another while hanging from a cable. Design and create a zip line that is safe for a hard-boiled egg. After designing a safety egg harness, connect the harness to fishing line or wire connected between two chairs of different heights using a paper clip. Learn to improve your zip line based on data. Attach a motion sensor at the bottom of your zip line and display a graph to show how smooth a ride your egg had!

Earthquakes happen when forces in the Earth cause violent shaking of the ground. Earthquakes can be very destructive to buildings and other man-made structures. Design and build various types of buildings, then test your buildings for earthquake resistance using a shake table and a force sensor that measures how hard a force pushes or pulls your building.

Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines the wedge, wheel and axle, lever, inclined plane, screw, and pulley in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today. In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and selecting a construction site. The six simple machines are examined in more depth in subsequent lessons in this unit.

Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane, screw and pulley in the context of the construction of a pyramid, gaining insights into tools that have been used since ancient times and are still important today. Through numerous hands-on activities, students imagine themselves as ancient engineers building a pyramid. Student teams evaluate and select a construction site, design a pyramid, perform materials calculations, test a variety of cutting wedges on different materials, design a small-scale cart/lever transport system to convey building materials, experiment with the angle of inclination and pull force on an inclined plane, see how a pulley can change the direction of force, and learn the differences between fixed, movable and combined pulleys. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

In this unit, students wonder about the physical drivers of ocean movement, explore density differences, and take a look at some tiny creatures who struggle to keep their place in the water column in the midst of all that ocean motion.
Each unit of the Explore the Salish Sea curriculum contains a detailed unit plan, a slideshow, student journal, and assessments. All elements are adaptable and can be tailored to your local community.

Students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines.

In this Unit, students embark on a mission to create a campaign which promotes seat belt use for a teenage audience. In the context of this project, students explore NGSS PE’s 3-PS2-2, 3-PS2-1, 3-5-ETS1-1, 3-PS2-3, and 3-PS2-4 while investigating the effects of balanced and unbalanced forces acting on an object. Through a series of collect evidence to write a claim based on evidence for why seatbelts are important.

Students will construct CD hovercraft and apply Newton's laws of motion to make them work. They will also investigate how hovercraft reduce friction; learn how the technology is used in training astronauts for space missions; and design their own hovercraft competitions.
