This Lesson provides two different activities that require students to measure energy outputs and inputs to determine the efficiency of conversions and simple systems. One of the activities includes Lego motors and accomplishing work. The other investigates energy for heating water. They learn about by products of energy conversions and how to improve upon efficiency. The teacher can choose to use either of these or both of these. The calculations in the water heating experiment are more complicated than in the Lego motor activity. Thus, the heating activity is suitable for older students, only the Lego motor activity suitable for younger students.

Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual components of light. After finding the desired angles, students use what they have learned to design their own spectrograph enclosure.

This short video and interactive assessment activity is designed to teach fourth graders about estimating measure by image: centimeters or meters?.

This short video and interactive assessment activity is designed to teach fifth graders about estimating the measure of objects by image: feet or inches?.

This lesson unit is intended to help you assess how well students are able to: solve simple problems involving ratio and direct proportion; choose an appropriate sampling method; and collect discrete data and record them using a frequency table.

This short video and interactive assessment activity is designed to teach fourth graders about estimating measure by description - multiple choice.

Harry estimates how long it will take him to get to the front of a long ticket line in this Cyberchase video segment.

This short video and interactive assessment activity is designed to teach fifth graders about estimating the measure of items by description: inches, feet, or yards?.

In this activity, students will use the accusative of extent and genitive of quality to describe personal items or items provided by the instructor. Students will also gain practice with numerals one through twenty in expressing inches (digiti and unicae) and feet (pedes).

Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoirs.

The CyberSquad tests which broom can travel the furthest in five seconds in this video from Cyberchase.

Students have the opportunity to create and interpret data from simple daily questions.

This video provides a basic overview of unemployment and how it is measured. It also provides an understanding of the FOMC's role in promoting maximum employment and price stability.

This task provides students the opportunity to make use of units to find the gas need (N-Q.1). The key point is for them to explain their choices. This task provides an opportunity for students to practice MP2, Reason abstractly and quantitatively, and MP3, Construct viable arguments and critique the reasoning of others.

Using the LEGO® NXT robotics kit, students construct and program robots to illustrate and explore the Fibonacci sequence. Within teams, students are assigned roles: group leader, chassis builder, arm builder, chief programmer, and Fibonacci verifier. By designing a robot that moves based on the Fibonacci sequence of numbers, they can better visualize how quickly the numbers in the sequence grow. To program the robot to move according to these numbers, students break down the sequence into simple algebraic equations so that the computer can understand the Fibonacci sequence.

In this video segment from Cyberchase, through addition and regrouping in base sixty, Matt helps Digit figure out what time his CyberSoufflŰ__ŒŰÖ will be done.

In this activity students will learn the basic concept of Global Positioning Systems (GPS) using triangulation and measurement on a small scale in the classroom. Students discover how GPS and navigation integrate mathematic and scientific concepts to create a standard for locating people and objects. This activity helps students understand both the need for and methods of navigation.

The purpose of this task is to give 4th grade students a problem involving an unknown quantity that has a clear visual representation. Students must understand that the four interior angles of a rectangle are all right angles and that right angles have a measure of 90_ and that angle measure is additive.

This short video and interactive assessment activity is designed to teach second graders about finding the amount of water with illustrations and calculations.

This short video and interactive assessment activity is designed to teach second graders about finding the capacity of water with illustrations (metric units).
