As an AI language model, I can provide some ideas for each topic:

Computer Science: - Introduce basic coding concepts through games and activities, such as sequencing, loops, and conditionals. - Teach students how to use educational programming tools like Scratch or Code.org. - Discuss the importance of internet safety and responsible use of technology.

2nd Grade Measuring: - Teach students how to measure length, weight, and volume using non-standard units like paperclips, blocks, or cups. - Introduce the concept of time and how to read a clock. - Use real-life examples to help students understand the importance of measuring, such as baking or building.

Robotics: - Introduce students to the basics of robotics, including sensors, motors, and programming. - Use robotics kits like LEGO Mindstorms to teach students how to build and program robots. - Discuss the real-world applications of robotics, such as in manufacturing, healthcare, and space exploration.
