A train travelled 50 miles in the first hour, 70 miles in the second hour, 30 miles in the third hour, and 50 miles in the fourth hour. Draw a line graph showing the rate of speed of the train's trip.
The graph should show a line increasing to 50 at hour 1, increasing to 70 at hour 2, decreasing to 30 at hour 3 and increasing back to 50 at hour 4.

Steph has an irregular-shaped object and she wants to find out the density. What two things does she need to measure and how can she do that?
Steph needs to get the mass of the object by using a balance. Then she needs to use displacement to get the volume (Fill a cylinder with water, measure it, put the object in the water, measure it and subtract the two amounts to get the volume).

What is the difference between Energy Conservation and Energy Efficiency?
Energy conservation is any behavior that results in the use of less energy and Energy Efficiency is the use of technology that requires less energy to perform the same function.
IE: Conservation is what you do and Efficiency is what you use.
