Third graders discover a connection between numbers of things in groups and groups. They solve number line puzzles for multiplications and identify data for 3 riddles in a multiplication context. They use number lines as sources for...

Students assess what a dichotomous key is and how it identifies objects in a group through a process of answering yes/no-type questions about certain objects. They examine an interactive graphic key on sea turtles and then create their...

Students experiment with magnetism. In this science lesson, students are divided into cooperative learning groups and use the scientific method to test their hypothesis. Each group performs a different experiment.

Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.

Students explore area around schoolyard by participating in scavenger hunt, examine things that live there, such as noxious weeds, develop observation skills by using five senses, and find and identify ten to fifteen local, natural objects.

Third graders examine and explore a variety of ways to measure length. They discuss how to measure large objects using the end-to-end method, and in small groups measure the length of the room using the end-to-end method with a...

Fourth graders explore Newton's second law of motion, testing and identifying the characteristics of objects that makes them easier or harder to push. They identify what types of objects are the hardest to move, then test a variety of...

Young scholars learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students explore craters that objects of different sizes and weights (marbles, Ping-Pong balls, and aluminum foil balls) create.

Students observe falling objects. In this lesson about gravity, students work in groups to determine how objects fall. Students determine speed of objects falling and whether weight is a factor. Students understand the concept of gravity.

Students analyze objects by one or more attributes. In this sorting lesson, students use manipulatives and string or yarn to create a sorting game. Students read books and items from the classroom to sort. 

Fourth graders design a classification system to categorize animate and inanimate objects. They discuss the advantages of grouping things as they classify buttons, leaves, shells.

Fourth graders discover the principles and uses of gears noting that they can be used to change the direction of motion or the speed of an object. They may also change the force and/or distance through which an object turns. They then...

In this space science worksheet, students collect data that includes information in a chart or graph to display in a group. They identify and describe various planet features of a specific planet of choice. Students write notes and the...

Students measure distances using indirect measurements. In this geometry lesson, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.

Students are introduced to the concept of classification as it relates to objects, information, and characteristics.  In this classification lesson, students research a variety of animals. Students study the Linnaeus's system of...

Sixth graders, in groups, research the culture of an ancient civilization. They use the Internet to locate artifacts that illustrate different elements of culture, write a description and analysis of each piece and present their work to...

Students examine the physical properties of matter. They identify and classify a variety of objects based on their physical properties.

Students identify the relationship between kinetic energy, mass, and velocity. Then they explain and graph the relationship between kinetic energy and mass. Students also predict the impact of objects of different mass and velocity on...

Students explore how various ramps affect the rate of speed of a rolling object. In this physics activity, students work in groups to build a ramp out of various materials. Students test and record the rate of speed of a rolling object...

Students explore the observable properties of matter. They develop two binary classification systems using concrete objects. based on two different properties of the concrete objects.

Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...

Young scholars create an art piece using recycled objects. In this environmental instructional activity, students collect and sort recycled objects and create a three dimensional art piece.

Tenth graders analyze graphs and by comparing trees. In this geometry activity, 10th graders investigate the use of different graphs using bar and regular graphs. They work groups at the computer.

Students examine new evidence of violent behavior in dolphins as a springboard for research on various dolphin behaviors, such as communication, feeding patterns, group behaviors, parenting, navigation, and interactions with humans.
