Using planetary maps, students will be able to read cartographic information and compare the environmental conditions of Io to those Earth. They will understand the conditions needed for life to exist, and be able to explain why it cannot exist on Io.

Using planetary maps, students will be able to read cartographic information and compare the environmental conditions of Mars to those Earth. They will understand the conditions needed for life to exist, and be able to explain why it cannot exist on Mars.

Using planetary maps, students will be able to read cartographic information and compare the environmental conditions of Pluto/Charon to those Earth. They will understand the conditions needed for life to exist, and be able to explain why it cannot exist on Pluto or Charon.

Using planetary maps, students will be able to read cartographic information and compare the environmental conditions of The Moon to those Earth. They will understand the conditions needed for life to exist, and be able to explain why it cannot exist on The Moon.

Using planetary maps, students will be able to read cartographic information and compare the environmental conditions of Titan to those Earth. They will understand the conditions needed for life to exist, and be able to explain why it cannot exist on Titan.

Using planetary maps, students will be able to read cartographic information and compare the environmental conditions of Venus to those Earth. They will understand the conditions needed for life to exist, and be able to explain why it cannot exist on Venus.

Practice vocabulary on the go! The original idea conceived by a fellow Chinese language student, this flashcard exercise is an engaging and effective way to review vocabulary terms from the convenience of your mobile device.

Chinese Take-In provides an interactive environment where first-year Chinese learners can practice listening outside the classroom according to individual needs and paces while receiving immediate feedback.

Created by student request, this set of basic word-order exercises will help beginners practice the foundational skills of how to use the language in the right order.

In this task students use different representations to analyze the relationship between two quantities and to solve a real world problem. The situation presented provides a good opportunity to make connections between the information provided by tables, graphs and equations.

Working in engineering project teams, students evaluate sites for the construction of a pyramid. They base their decision on site features as provided by a surveyor's report; distance from the quarry, river and palace; and other factors they deem important to the project based on their team's values and priorities.

This task suggests methods of introducing and continuing choral counting in the classroom.

Teachers (and then students) lead the class in chanting numbers from 1 to 120.

The purpose of this task is for students to find different pairs of numbers that sum to 7.

This task is primarily about volume and surface area, although it also gives students an early look at converting between measurements in scale models and the real objects they correspond to.

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use alcohol and chromatography paper to separate the components of black and colored marker ink. Students witness first-hand how components of a solution can be separated, even when those individual components are not visible in solution.

Although this task is fairly straightforward, it is worth noticing that it does not explicitly tell students to look for intersection points when they graph the circle and the line. Thus, in addition to assessing whether they can solve the system of equations, it is assessing a simple but important piece of conceptual understanding, namely the correspondence between intersection points of the two graphs and solutions of the system.

Students are introduced to several key concepts of electronic circuits. They learn about some of the physics behind circuits, the key components in a circuit and their pervasiveness in our homes and everyday lives. Students learn about Ohm's Law and how it is used to analyze circuits.

Students use the same method as in the activity from lesson 2 of this unit to explore the magnetism due to electric current instead of a permanent magnet. Students use a compass and circuit to trace the magnetic field lines induced by the electric current moving through the wire. Students develop an understanding of the effect of the electrical current on the compass needle through the induced magnetic field and understand the complexity of a three dimensional field system.

This task shows that the three perpendicular bisectors of the sides of a triangle all meet in a point, using the characterization of the perpendicular bisector of a line segment as the set of points equidistant from the two ends of the segment. The point so constructed is called the circumcenter of the triangle.
