After the unit on Electricity and Magnetism, students are given the opportunity to experience practical applications of the concept as they construct their own headphones and listen to music from their I-pods.

This activity is a discovery lab where students will discover what does and does not stick to a magnet.

This cooperative classroom activity will allow students to apply their knowledge of magnetism and electricity. The students will create a circuit that lights a flashlight bulb and simultaneously practice the skills of prediction, observation, inferrence, recording, investigation and communication.

This activity is an introduction to a magnifying glass as a science tool.

The purpose of this task is for students to find different pairs of numbers that sum to 9.

In this activity, students use their own creativity (and their bodies) to make longitudinal and transverse waves. Through the use of common items, they will investigate the different between longitudinal and transverse waves.

This instructional task gives students a hands-on experience with composing and decomposing geometric figures.

Students learn about the difference between temperature and thermal energy. They build a thermometer using simple materials and develop their own scale for measuring temperature. They compare their thermometer to a commercial thermometer, and get a sense for why engineers need to understand the properties of thermal energy.

This activity is a combination outdoor/indoor lab where students will collect natural materials from the environment and use them to create both a mold and cast model of a fossil. Students will learn how a fossil is formed and why scientists use models to help them understand how things work and develop.

This task is for students who know how to use base 10 blocks.

This task is a straightforward task related to adding fractions with the same denominator. The main purpose is to emphasize that there are many ways to decompose a fraction as a sum of fractions, similar to decompositions of whole numbers that students should have seen in earlier grades.

This activity is a guided discovery where students make chemical mixtures using sodium, learn about the Periodic Table, view salt under a microscope, and have a final result of bath salts for the bathtub

This tasks lends itself very well to multiple solution methods. Students may learn a lot by comparing different methods. Students who are already comfortable with fraction multiplication can go straight to the numeric solutions given below. Students who are still unsure of the meanings of these operations can draw pictures or diagrams.

Students redesign and justify the packaging used in consumer products. Design criteria include reducing the amount of packaging material by 25%.

This is the first of two fraction division tasks that use similar contexts to highlight the difference between the ŇNumber of Groups UnknownÓ a.k.a. ŇHow many groups?Ó (Variation 1) and ŇGroup Size UnknownÓ a.k.a. ŇHow many in each group?Ó (Variation 2) division problems.

This is the second of two fraction division tasks that use similar contexts to highlight the difference between the ŇNumber of Groups UnknownÓ a.k.a. ŇHow many groups?Ó (Variation 1) and ŇGroup Size UnknownÓ a.k.a. ŇHow many in each group?Ó (Variation 2) division problems.

This is a lab designed to allow students to create and collect gas through a simple acid-metal reaction.

As a weighted plastic egg is dropped into a tub of flour, students see the effect that different heights and masses of the same object have on the overall energy of that object while observing a classic example of potential (stored) energy transferred to kinetic energy (motion). The plastic egg's mass is altered by adding pennies inside it. Because the egg's shape remains constant, and only the mass and height are varied, students can directly visualize how these factors influence the amounts of energy that the eggs carry for each experiment, verified by measurement of the resulting impact craters. Students learn the equations for kinetic and potential energy and then make predictions about the depths of the resulting craters for drops of different masses and heights. They collect and graph their data, comparing it to their predictions, and verifying the relationships described by the equations. This classroom demonstration is also suitable as a small group activity.

This JiTT exercise uses a real-life example to pose a question to students about the nature of "rationality" as typically used in economics. In this case, the focus is on fixed vs. marginal costs and the use of marginal analysis by economists to make "rational" economic decisions.

The purpose of this instructional task is to motivate a discussion about adding fractions and the meaning of the common denominator. The different parts of the task have students moving back and forth between the abstract representation of the fractions and the meaning of the fractions in the context.
