Math And Science In Fe7B

Hello everybody! Happy spring is just around the corner? Well, that is not the case for me. Personally, I wish SUMMER was just around the corner. Well, back to work in Fe7B! We have just finished our math unit on Patterning and Algebra! Now, we were just given a math assignment due tomorrow. The question is: How many pianos are there in the city Toronto?? Using an estimated guess, my group calculated that there are 212 000 pianos in Toronto. Hopefully, we aren't too far off! But, how does one start to tackle this problem? It is not very difficult. First think, where are pianos found? Most commonly they are found in homes, schools, and music stores. Take into consideration that pianos are very expensive and probably are not very common throughout all of Toronto's areas. Also, the population of Toronto would be helpful and useful when trying to estimate the number of pianos. You definitely do not want to guess that there are 10.5 million pianos in Toronto when he population is much less. Not very likely! Also, if you think that there are approximately 3 people in every household, you could divide 3 from the population of Toronto to find the total number of households in all of Toronto. After that, you can then guess how many households have pianos (possibly 1 out of every 4 homes) and then divide your number of households by 4 to get your total number of pianos throughout all the homes in Toronto! This math question helps students make more accurate and educated estimations in math!
As for science, we are soon going to finish up our unit in science on pure substances and mixtures. We have recently been given a science assignment. The objective is to design how you would construct a science procedure of mixing the solute salt with the solvent water. You have to control variables, meaning, keeping everything constant, except for what you are trying to find. Besides the assignment, we just learned about maple syrup and sugar. Both are processed similarly. Example: Both are boiled to dilute the water and create a different substance. Also, both are filtered during the process. Most importantly, the raw materials create a variety of products. For example: Sap can create maple syrup and maple sugar. Also, sugar can and sugar beets create plain white sugar, brown sugar, and molasses. I guess you learn something new everyday!

That is all for now! I'll blog soon!
