What does "ranging" mean in this context?
Controlling the future: Creating robots that do your biding
Welcome to a current presentation of robotics using computer science principles. The links below will connect you to how-to readings and step-by-step instructions that will allow you to build a robotic boat, design your own robot, and ace the AP Computer Science Principles exam.
This program uses two freely available software packages: MIT App Inventor and Arduino. You may want to purchase the Arduino components, but it’s not absolutely necessary. (If you need help affording these components, please contact the edMe Foundation.) These websites contain questions to help you learn and places to share your own unique flair in robotics. A big part of designing technologies is learning from mistakes; please do not get discourage but use the feedback provided to learn and grow.

Omar’s Calculus Notes
Two times a week, please upload a picture (or two) of the notes you took or problems you solved as part of your calculus studying. Not only does this help you stay accountable to yourself, but it will help me be more prepared for our sessions.
Use the interface below, by allowing this page to use your phone or computer’s camera. Then, click “Take Photo”. If you are unhappy with the photo quality, just click “Take Photo” again. When you have the photo you want, click “Save Photo” and I can see it in the database. Thanks for helping me perfect this technology! (p.s. When you are done with the page, close it. It can drain your battery quickly.)

Kushaan’s Physics Note Tracker
After lab on Thursday, please send me a picture (or two) of your notes. As we discussed, there is a reason you had THIS lab at THIS point in the course. What concepts are they teaching you with this experiment?

Sun-index
You know the Sun! It gives us light and heat. Earth is always spinning and when we face the Sun it’s day. Night is when we are pointed toward the outside of the solar system.
Here is a model of the Sun. What do you notice?
Rube Goldberg Machines
These machines are kind of like mazes, but they solve problems to move the energy down the line. Here is a good example to start with.
Here is the world record according to Guinness!
Quantum Computing begins
Quantum computing is important to study for a few very different reasons.
- Scientists (like you) are exploring new things everyday. Science is always learning new things and asking new questions.
- The best thing you can do as a learner is ask lots of questions. It’s easy to be quiet; it’s smart to ask.
- Quantum computing will solve problems in ways that we can hardly imagine today. This tool will be important for decades to come.
Long Division
After you have memorized all your multiplication and division facts, then you are ready for long division! This procedural allows you to divide really large numbers. Here is an example of what you will be doing:
You can remember these steps by:
- Divide the first digit by the divisor
- Multiply the divisor by the answer in the first column
- Subtract the product from the divisor
- Bring down the next digit and repeat.
You can solve these videos to practice this strategy.
Here are two great teaching videos.
Water Filtration Activity
Getting clean drinking water is one of the most important things we do as a country. Many STEM activities (like this one from Teach Engineering) encourage you to work in teams. If you can’t work in teams, these steps make it possible for you to do this activity at home with common materials:
TAKE YOUR NOTES HERE
- Dirty Water (add coffee grounds, grass, rocks, etc.)
- 2 Measuring container (one for dirty water, one to catch cleaned water)
- Create filters using water bottles (you can also use two-liter bottles but they are heavier and harder to use)
- Rubber bands to secure layers
Choices for filter:
- Large filtering components (gravel, pebbles, rocks, sand)
- Filtering materials (screens, coffee filters, cheese cloths, plastic bags)
- Cleaning liquids (soaps, air, cleaning supplies)
Readings to help you think through the process:
- NASA’s teaching on this activity: https://www.jpl.nasa.gov/edu/learn/project/make-a-water-filter/
- Recent Filtration Research: https://www.nsf.gov/discoveries/disc_summ.jsp?cntn_id=301941
- Water Education Organization: https://www.watereducation.org/water-kids
This video does a great job describing the big picture of this activity.
The video omits using charcoal which is an important part of this process (if you still have a bag hanging around!).
If you are interested in digging deeper, these videos explore these topics in great detail.
