This activity is a forensic based physical science inquiry investigation where students collaborate in groups and use observations to determine how Newton's Laws of Motion are applied in finding evidence in a car and truck trailer accident. Their evidence will be used in a presentation to verify consistency in police and witness reports to support the plantiff or defendent in the court case.

In this 5-lesson multi-media unit, students will explore various real-world applications of different forms of measurement, including time and distance. They will make estimations and calculations. Throughout the unit, students will be using online resources to familiarize themselves with coral reefs, the nation of Belize, and to plan a pretend scuba diving trip. Activity sheets (pdf), links to online resources, assessment options and other commentary are provided.

This activity is a year long project observing the changes in a specific tree. It includes using all the senses in the observation and making two different booklets to record what we observe. It also includes several picture story books that enhance the lesson.

In this math meets physics lesson, learners encounter the magical effect of reflection as they use a mirror to visually experience the concept of doubling quantities. This experience focuses learners' attention to using doubles as a strategy to make number operations easier, specifically addition. The book "Two of Everything" by Lily Toy Hong is used to introduce learners to these concepts. A game is used for discovery and practice and writing is used as closure to this lesson. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

This is an activity in which students use their senses to describe their garden. This is a guided inquiry lesson.

This task is intended to help model a concrete situation with geometry. Placing the seven pennies in a circular pattern is a concrete and fun experiment which leads to a genuine mathematical question: does the physical model with pennies give insight into what happens with seven circles in the plane?

Students are introduced to brainstorming and the design process in problem solving as it relates to engineering. They perform an activity to develop and understand problem solving with an emphasis on learning from history. Using only paper, straws, tape and paper clips, they create structures that can support the weight of at least one textbook. In their first attempts to build the structures, they build whatever comes to mind. For the second trial, they examine examples of successful buildings from history and try again.

Students learn how engineering design is applied to solve healthcare problems by using an engineering tool called simulation. While engineering design is commonly used to study and design everything from bridges, factories, airports to space shuttles, the use of engineering design to study healthcare administration and delivery is a relatively new concept.

This 2-lesson unit offers a variety of activities and games to help students master multiplication facts with 6 and 7 as factors. It is intended for students who understand the process of multiplication and have mastered the facts where 0, 1, 2, 3, 4, and 5 are factors. Students make use of the effects and properties of multiplication, write and solve story problems, and develop materials and strategies to assist in becoming fluent with the facts. The unit includes questions for students and teachers, a printable multiplication chart, extension ideas, and link to a Virtual Spinner and an online Times Table applet (both catalogued separately).

The culminating energy project is introduced and the technical problem solving process is applied to get students started on the project. By the end of the class, students should have a good perspective on what they have already learned and what they still need to learn to complete the project.

This is a text that covers the standard topics in a sophomore-level course in discrete mathematics: logic, sets, proof techniques, basic number theory, functions, relations, and elementary combinatorics, with an emphasis on motivation. It explains and clarifies the unwritten conventions in mathematics, and guides the students through a detailed discussion on how a proof is revised from its draft to a final polished form. Hands-on exercises help students understand a concept soon after learning it. The text adopts a spiral approach: many topics are revisited multiple times, sometimes from a different perspective or at a higher level of complexity. The goal is to slowly develop students’ problem-solving and writing skills.

This activity is an investigation where students explore the properties of color and light, using mixtures of common everyday materials.

This activity is a lab investigation where students observe the four states of matter. At the end of the investigation students should be able to know that the differences among the physical states depend on the distance between the atoms or molecules and on the rate of movement of the atoms or molecules. And, that pressure and temperature control these two factors.

During this project, students will be working to cooperatively create a field guide to trees in the neighborhood near the school. In doing so they will be making observations, introduced to tree and plant anatomy and physiology, and will learn how to make and use dichotomous keys.

In this lesson, students deepen their understanding of the measurement of plane and solid shapes and use this understanding to solve problems. Students also identify and describe the properties of two-dimensional figures. Students are challenged to set a table for 22 using one unit lengths of paper (each unit length represents one student sitting at the table). They are asked to pretend that they all want to sit together for a dinner, and the table has to be rectangular. They must figure out what the table will look like if it must be rectangular and if everybody must sit at the table. They must determine what's the biggest table going to look like where everybody sits, and what's the smallest table going to look like where everybody sits. Students work to conceptually figure out relationships between perimeter and area in a creative and interactive way. They brainstorm ideas in groups, discuss as a class to determine the best options, and then physically set the two tables using strips of paper that represent "one unit" in length per person.

This activity teaches students weather terminology, how to interpret weather data, and make a weather prediction based on that data.

In this math lesson, learners listen to a poem about money from Shel Silverstein's "Where the Sidewalk Ends" and examine a quarter. Learners find sets of coins equivalent to a quarter using pennies, nickels and dimes. Learners also estimate and count coin collections and count by fives and tens using actual and online calculators and pose and answer coin puzzles.

In this math meets life science lesson, learners measure the circumference of local trees in order to calculate diameters. Learners use this information and a growth rate table to estimate the age of the trees. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

Students will classify elements as metals, non-metals and metalloids based on their observtions of appearance, conductivity, malleability and reactivity with dilute acid. They will observe the location of these groups on the periodic table.

This Java applet provides opportunities for creative problem solving while encouraging young students to estimate length and angle measure. Using the Turtle Pond Applet, students enter a sequence of commands to help the turtle get to the pond. Children can write their own solutions using LOGO commands and input them into the computer. The turtle will then move and leave a trail or path according to the instructions given. (N.B. the applet is an upgrade of one that supported the Lesson "Get the Turtle to the Pond," cataloged separately.)
