Weight,+Mass,+Capacity


 * Pretest/Post Test **
 * 10 questions, 2 sided **


 * TEKS: **

1.7 Measurement. The student directly compares the attributes of length, area, weight/mass, capacity, and temperature. The student uses comparative language to solve problems and answer questions. The student selects and uses nonstandard units to describe length.

1.7E Compare and order two or more containers according to capacity (from holds the most to holds the least).

1.7F Compare and order two or more objects according to weight/mass (from heaviest to lightest)


 * Core Components: **

1.7E
 * Directly compares two or more objects to see which will hold more and orders them by capacity.
 * Uses visual estimation as well as guess-and-check strategies to determine which container holds more or less than another.
 * Estimates the capacity of a variety of objects in relationship to each other.
 * Uses comparative language to justify solution strategies when solving problems.

1.7F
 * Uses estimation as well as guess-and-check strategies to determine which object weighs more or less than another.
 * Estimates the weight of a variety of objects in relationship to each other.
 * Directly compares the weight/mass of objects which vary in weight enough so that the fact that one is heavier than another can be detected conclusively and orders the objects from heaviest to lightest (or lightest to heaviest)

**Vocabulary:**


 * Whole Group Mini Lesson: **

Adapted from How Much Can it Hold Lesson- Define “capacity” as how much something will hold. When we talk about capacity, we use words like “holds more than, holds less than, holds the most, holds the least and holds the same amount." Show the class the assortment of containers and discuss how they are used in real life. Ask: Where have you seen these containers before? at school, at home, in the kitchen, at the store, or maybe in the kitchen? How do we use these containers? To hold things, to store things like leftovers, etc. Have students predict which will hold more or less

“I think container _ _ will hold less.” “I think container _ _ will hold more

Next demonstrate how students should investigate their predictions. Fill one of the cups with rice, beans, sand, peas, or water. Level the contents using the craft stick, and then pour the entire contents of that cup into the other cup.

Ask: • Did the contents of one cup not fill the other cup? • Does one cup hold less? • Did the contents of one cup spill over and out of the other cup? • Does one cup hold more?

Say: What is another way of saying, “Which object has the greatest capacity?” Which object holds the most? As you look at these pictures and try to decide which container holds the most, think about when you investigated the capacity of the containers

Engaged Learning Options:
 * Use assorted fruit to order by weight
 * Use pipettes to count number of drops of water the surface of a penny will hold; compare with nickel, quarter
 * Create scales using ruler, rubber band, paper clip, small drink cup. Place ruler on edge of desk, loop rubber band over free end, link paper clip to drink cup and rubber band. Press down on ruler and begin placing small objects in drink cup, notice how much the rubber band stretches

**Questioning:**

What is capacity? How can we use direct comparison to determine the capacity of something? How do we use direct comparison to determine how heavy or how light something is? Why is measuring weight important? How do we use knowledge of weight and capacity in our lives? What do we use to determine weight? Does size determine weight? Do size and shape determine capacity
