Follow-Up Questions - Homemade Water Balance

What is the fundamental concept about the metric system that makes it possible to measure the mass of an unknown object with water?

Since 1 mL of (pure) water is equal to one gram, you can easily measure the mass of an unknown object (with pure water) by knowing how much mL of water it equals to.

Any balance or scale has a maximum amount of mass it can measure. What is the maximum mass that your homemade water balance can measure?  Explain.

The bottle was originally 1.5 litres, but the top was cut off, so the maximum mass the homemade water balance can measure is probably 1,200 grams to 1,300 grams.

Parent / Student Agreements

Why do you think you are responsible enough to take your laptop home and back to school each day?

I think that I am responsible enough because I take good care of my things, and I am a fairly organized person.

How will you make sure that your laptop is charged each night? Where will you charge it? When? Explain your routine?

I will make sure my laptop is charged each night by charging it near enough for me to see a red light showing that it's being charged. I will charge my laptop either next to my bed, or on my table when I'm going to bed.

Think Before You Post... Leave A Good Digital Footprint

“A friend of mine was tagged in a picture drinking beer, it actually got her in trouble when she applied for a summer job,” states a person from the video, Facebook, YouTube, Texting: Rules of the Road for Kids. During the past laptop Bootcamp lessons, we have been learning about how you have to think before you post, because you may regret it later on. I learned that if you post the wrong things, it can harm you, and also the other people involved in the situation. To avoid any conflict, we were taught a couple of rules; protect your privacy, know that nothing is private online, assume everyone is watching, maintain a good reputation, treat others as you want to be treated, and follow the SAS Core Values.

Protecting your privacy is very important to know when you are on the internet, posting, and even in a chat room! It is unnecessary and unsafe to add personal information like your phone number, address, etc. This also applies to ‘know that nothing is private online’, because anyone can know and find out what you posted. “Anything you say or do, can be copied, pasted, and sent to gazillions of people, without your permission,” says a teenager from a Common Sense Media video. Even if the conversation or post is private it can still be forwarded and sent on to anybody when it’s online. Also, if you assume everyone is watching, there wouldn’t be situations where people have copied and pasted your work when you didn’t want to be public, because if you assume everyone is watching, you’d be more cautious of what you put online.

Maintaining a good reputation means people sees you as a good person and writer, and having a good reputation. Keeping a good reputation can also be the same as “treat other as you want to be treated” (or the Golden Rule), because everyone will see you as a good and appropriate person instead of a bad one. Following the Core Values is also important. If you follow the SAS Core Values; respect, responsibility, honesty, fairness, and compassion, you probably won’t have any online problems.

So next time you put something online, think about the positive digital footprint you should leave for the world to see.
