Name: Period Bell work April 18-22 Monday 4/18 SC.8.P.8.4 A tudent measured o 4.5 cm' pece cf alununun and calculated its density to be 2.7g/c. Based on the informotion given, is her caiculation accurale? The Images below chow the masses and compositians of sx cubes The cubes ach have &valme of 1 em. A. No, beccuse different-sized pieces of aluminum will have different densities. 8. No, because the volume of a sample of aluminum is not related to ita density. C. Unknown, because the mass of the cluminum sample was not provided. unpun saddo D. Yes, because the density of aluminum doesn't change based on the size of the sample. 105g Answer. Why: Tuesday 4/19 Students are given three cubes made of unidentified materials. They need to determine whether or not the three cubes are made of the same material. They measure the mass of each cube and record it in the table. A student immediately concludes that the cubes are made of three different materíals. .Cube Mass (g) 42 15 B. C. 7. What observation would best support the students' conclusion? A. The cubes all have the same volume. B. The cubes all have a shiny appearance. C. The cubes are all attracted to a magnet. D. The cubes all conduct heat. Wednesday 4/20 Janet and Ahmad are both doing a science project about.growing grass. They both sprinkle grass seed on a box of soil 10 cm by 15 cm by 5 cm deep. They plant their grass seed on the same day. They water the seeds with 50 mL of water every other day. After four days, the grass.seed sprouts. After three weeks, Ahmad's grass is 2 cm taller than Janet's. What might account for the difference in growth rates? A. the amount of.sun each box received B. the time of year the students planted the grass C. the box of soil Ahmad used for planting was much larger than Janet's soil box D. the number of seeds Ahmad planted was greater than the number Janet planted
