Back to School, Everyone

So, part of my own home-grown entertainment last night involved writing up a density assignment for an anonymous person that I live with. Don't these questions just make you want to jump back into Grade 7 and whip out your calculator?
Here is a small selection: (Remember, D=M/V)

1. Your backpack has a 43 L capacity. While backpacking in a foreign land, you find some fresh coffee beans which you want to take home to share with your family, so you empty out your bag and fill it with beans. If the coffee beans have a density of 0.561 kg/L, how heavy will your backpack be?

2. When you were backpacking (in question 1!) you also found some very tasty chocolate powder which you knew your mother would enjoy. If the density of this chocolate powder is 0.641 kg/L, and you filled your 43 L backpack with chocolate powder instead of coffee beans, how much heavier would your backpack be?

3. A mechanic drains 3.4 L of used fuel oil out of your car, and when he weighs it, he finds that it weighs 3.45 kilograms. What is the density of the oil? The mechanic fills your car up with 3.4 L of clean fuel oil. If clean fuel oil has a density of 0.89012 kg/L, how much lighter will your car be with the new oil?

4. You want to buy as many apples as you can from the local farm. Apples are sold for $2.50 for a 10 kg bag. If the density of apples is 0.641 kg/L, and your 1995 Ford Escort wagon has a cargo capacity of 2,563 L, how many kilograms of apples can you stuff into your car, and how much will it cost?

Good-bye Lungs

My will broken by my Valentine's Day-tempered mood cooperating with my till-now curiousity in the dangerous things of life has led to a monumentous event this very evening. After years of steadfast disapproval and a dedicated concern for both my health and the health of those around me, I succumbed to a few puffs on Mike's pipe. How, indeed, this occurred I still am not sure, but I can be sure that it did happen, as I can still remember the flavour and perhaps when I wake up coughing my lungs out in the middle of the night, I will remember it even more. To be honest, it wasn't really all that bad, but it also wasn't really all that different than what I thought it would be. I'll still take chocolate over tobacco, though.

Fun Weekend

I know it's been a while since the weekend was over, being that it's almost tomorrow and tomorrow is Wednesday and Wednesday is semi-officially the very middle of the week, but I still want to post a few pictures from Saturday evening, because we had such a good time. Rebekah and Mike and I journeyed out to St. Catherines to visit Rick and Elaine at their home. We had a wonderful supper with them, and then headed out to see Niagara Falls. This visit to what should be listed as one of the seven wonders of the natural world left us amazed at the wonders of creation, as well as frozen somewhat solid. My fingers have just recently thawed, and that is my excuse for not blogging about the weekend till now.

So Teacherly!

So, my handsome husband is having his first official job interview tonight, at the Emmanuel Canadian Reformed Highschool in Fergus! He is both excited and serious about this interview and the prospects it offers, and although he may not admit it readily, I think he's also a wee little bit anxious - he doesn't even want to have any coffee! I'm sure he'll do just magnificently, though, as he is both confident and sincere.
And yet there is still smiles in this calm before the storm (well I don't know about it being a storm, but I wanted to use the metaphor) . . . does a whoopee cushion have any place in a job interview? Mike also just asked me if I would please dye his hair on the way to Fergus tonight. Well, perhaps not. I think he looks just great right now:

What a teacherly guy! Wouldn't you hire him in a flash?
