Grade 9 chemistry:

 

A metal with a mass of 0.74 kg occupies a volume of 35 cm3. Calculate the density of the metal. Use G.R.A.S.P.

Grade 9 chemistry:

 Zinc has a density of 7.13 g/cm3. Nasra takes a small piece of zinc and puts it into a graduated cylinder with 30 mL of water. She sees the water level in the graduated cylinder rise to 58 mL. Help Nasra determine the mass of the piece of zinc. Use G.R.A.S.P. (Given, Required, Analysis, Solution, Paraphrase) to show your work. 

Grade 9 Science experiment:

Experiment:  Compare brands of paper towels, to see which holds the most liquid. The independent variable in your experiment would be the brand of paper towel. The dependent variable would be the amount of liquid absorbed by the paper towel.

Come up with a problem, explain how you are going to control the experiment using a dependent variable, and use appropriate formats for displaying the observed and recorded data.
