Do Now

October 6th, 2015

Suppose you are at a candy store where you get to bring your own box and fill it with as many packs of candy as it can hold! The owner of the store wants to know how many packages of candy will fit into the box.

Things to think about:

  1. What do you need to know about your box?
  2. What tools might you need?
  3. Essentially, you are trying to figure out how much room, or SPACE, your box has to hold for candy. What scientific term could you add to this?

  • Things to think about!!!
  • How did you come up with your prediction for box 1? Did you count every box in the pattern? Did you count the boxes when it was put into a shape? How did you do it?
  • When you put your cubes into the box, was your prediction correct?
  • Did you notice a pattern or a SYSTEM or a FORMULA that took place after you build the 2nd box?
  • Based on what you did for the 1st box, did you predict in a different way for the 2nd box?
  • .How did you measure the volume of this box? What is the formula to measure a rectangular prism?
  • IF you know the formula, would you still need a ruler for this activity???
  1. Why do we use cm3 as a unit for volume? (Think-how many measurements are we taking? L x W x H--)

HOW MANY CUBES??? Name/Date/Period

The purpose of the lab activity was to learn how to calculate the formula for volume of a rectangular prism by figuring out how many cubes could fit into the box.

My prediction was (incorrect or correct). I calculated….(what was your prediction?).

I came up with this prediction by…(how did you come up with this number? EXPLAIN HOW. USE YESTERDAY’S DO NOW).

*Some errors in the lab consisted of the grid boxes being 1mm less than the actual cubes. This caused my actual measurement to be slightly off because I couldn’t fit the cubes in the box I designed.

*Another error in the lab was that I wasn’t clear how to measure volume when I was measuring the first box. However I figured it out when I was calculating the 2nd box.

***(If you didn’t have that problem, DON’T state it!)

My lab could have been different if the size of the cubes on the grid were exactly to size.

MORE TO THINK ABOUT!!!

CHALLENGE YOUR CANDY MIND!

Suppose I gave you this shoebox (you can get one!). How many cubes could you fit in it? What’s your strategy?
