13 _______ + ______ + _______ = ________ g Measuring MassWe will be using triple-beam balances to find the mass of various objects.The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up.Once you have balanced the scale, you add up the amounts on each beam to find the total mass.What would be the mass of the object measured in the picture?_______ + ______ + _______ = ________ g300 g70 g3.4 g373.4Top Image: Bottom Image:
14 Measuring Mass – Triple-Beam Balance 1st – Place the film canister on the scale.2nd – Slide the large weight to the right until the arm drops below the line. Move the rider back one groove. Make sure it “locks” into place.3rd – Repeat this process with the top weight. When the arm moves below the line, back it up one groove.4th – Slide the small weight on the front beam until the lines match up.5th – Add the amounts on each beam to find the total mass to the nearest tenth of a gram.Click here to try an online activity.

18 Measuring VolumeWe will be using graduated cylinders to find the volume of liquids and other objects.Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water.What is the volume of water in the cylinder? _____mL43What causes the meniscus?A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.Top Image: Bottom Image:

21 Graphing in Science Most Common Types of Graphs: Bar Circle Line Graphs are a visual representation of data that reveals patterns or trends not easily seen by numbers.
22 Creating a Graph 1. Create axes. 2. Label axes. 3. Create the scales. Number of Reindeer Needed to DeliverPresents the Santa Roos’s Studentsx-axis = horizontal axisy-axis = vertical axis32.

23 Useful Graph Information linear graph-graph whose data creates a straight line.graph whose data does not create a straight line.nonlinear graph-slope -a line that indicates the change in the independent variable to the change in the dependent variable ( y changes to x).origin -where x & y axes meet.coordinate -pair of numbers that indicate a position on a graph.
