LEARNING OBJECTIVES

• Define mass as the amount of matter in an object. 
• Define weight as the force of gravity on an object. 
• Use a balance to measure mass. 
• Use a spring scale to measure weight. 
• Discover that the weight of an object changes when it is moved to another planet. 
• Discover that the mass of an object is constant regardless of where it is located. 

VOCABULARY

• balance, force, gravity, mass, newton, spring scale, weight

ASSIGNMENT

Part 1 : Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. Your weight is the pull of gravity on your body. Suppose you step on a bathroom scale onthe Moon. How would your weight on the Moon compare to your weight on Earth?
   A. greater on the Moon B. less on the Moon C. same on Earth and the Moon
2. Your mass is the amount of matter, or “stuff,” in your body. How would your mass on theMoon compare to your mass on Earth? A. greater on the Moon B. less on the Moon C. same on Earth and the Moon

Part 2 : Definition

• Search on internet the definition of mass and write it down in your notebook
• Search on internet the definition of weight and write it down in your notebook

Part 3 : Gizmo Warm-up

On the Weight and Mass Gizmo, you can use a balance to compare the masses of objects.

1. Place the dog on the right pan of the balance. What happens? _____________________________
2. Place the 5-kilogram (kg) mass on the other pan. Which has more mass, the dog or the 5-kg mass?__________________________________________
3. The 5-kg mass is heavier than the dog, so take it off the pan and place a 1-kg mass on the pan. Add 1-kg masses to the left pan until it goes down. Then take one of the 1-kg masses off the pan so that the masses are above the dog.
4. Use this process of adding and subtracting other masses from the left pan until the two pans are balanced. Add up all the masses on the left pan. This is equal to the mass of the dog.What is the mass of the dog? _________________________________________________ You can check your answer by clicking the center of the cross beam of the balance.

Activity A

!!!Select beginner!!!

Question: How do we find patterns?

1. Collect data: Place the brown frog on any blue lily pad. Record the colors of the lily pads it visits in order. Write R for red, B for blue, and G for green. Record the first 15 hops.____________________________________________________________________ _____
2. Analyze: Put the brown frog on other pads and watch. What pattern does it seem to follow? _________________________________________________________________________
3. Observe: Click Catch all and repeat the above steps with the pink frog.
   A. What pattern does the pink frog follow?___________________________________B. Does its pattern depend on where it starts?Explain.____________________________________________________________________________________________
4. Find the pattern: What pattern does the yellow frog follow? __________________________ _________________________________________________________________________
5. Extend: Describe the red frog’s pattern. _________________________________________ _________________________________________________________________________ _________________________________________________________________________
6. Challenge: Compare the purple and red frogs. (Hint: Pay attention to more than just color.) A. How are their patterns similar?__________________________________________ ___________________________________________________________________B. How are they different?___________________________________________________________________________________________________________________

Activity B

!!!Select advanced!!!

Question: How can we gain confidence in the patterns we see?

1. Form hypothesis: Put the yellow frog on any pad. Observe it carefully. Try it on other pads. When you think you understand the frog’s behavior, write your belief, or hypothesis, below._________________________________________________________________________ _________________________________________________________________________
2. Predict: The true test of a hypothesis is if it predicts the results of experiments you have not yet tried. You should not trust a pattern until it correctly predicts the results of a test.Use your hypothesis to fill in the two sentences below.A. From the blue pad at lower left, the yellow frog will next jump to a__________pad. B. From the red pad at lower right, the yellow frog will next jump to a__________pad.
3. Test: Run experiments to test your predictions. Were you correct both times? ____________
   •   If one of your predictions was wrong, your hypothesis has been disproven.
   •   If your predictions were correct, your tests support your hypothesis.
   •   If enough experiments support a hypothesis, it can become a theory.
4. Form hypothesis: Now observe the pink frog carefully. What pattern does it repeat? _________________________________________________________________________
5. Predict: What are the next 10 colors the pink frog will visit if you start it at the bottom left? ________________________________________________________________________
6. Test: Test your hypothesis. What happened? _____________________________________
7. Challenge: Can you ever absolutely prove that a hypothesis is correct? Explain. _________ _________________________________________________________________________ _________________________________________________________________________
