We’re thrilled to bring you a brand-new interactive activity that combines environmental awareness with angle and measurement skills! Ocean Sweeper challenges students in grades 4, 5, and 6 to tackle ocean pollution, one piece of debris at a time, while sharpening their understanding of angles.
Angle Measurement
Students will use the laser guide to determine the angle of the trash so they can vacuum up the trash! In this example, the trash is positioned at 45 degrees, while the vacuum begins at 0 degrees. With certain controls disabled, students must strategically change the vacuum’s placement to collect the debris effectively. As they advance through the levels, they should be prepared for increased challenges—more gauges will become inactive, enhancing the difficulty and honing their measuring skills!
Angle Addition
- When gauges become unavailable, students will need to apply angle addition to align the submarine with the trash! In this scenario, the laser guide is malfunctioning, and the vacuum is locked at 45 degrees. The trash is located at 120 degrees, so students must adjust the submarine by an additional 75 degrees to perfectly align the vacuum with the trash. As they progress through the levels, they can expect even less information from the gauges, encouraging them to rely on their protractor for success!
Angle Subtraction
- To collect the trash at 70 degrees, students will need to subtract the angles (using a negative sign) and rotate the submarine clockwise. The vacuum is locked at 145 degrees, much like the previous example, so they must account for that when adjusting the submarine, turning it 75 degrees. As they progress, they will once again have less and less information from the gauges, so their protractor skills will need to be sharp!
