Special needs students explore why certain objects sink or float. They will make predictions on what objects will sink or float. Students conduct an experiment using a large bowl of water and several objects and test their predictions....

Students play a game to realize the rules of signs.

The first exercise in a series of worksheets, this handout asks learners to read 10 sets of sentences and choose the one with no errors in structure. Tip: Find all of the worksheets on parallel structure throughout our website and create...

Students develop their awareness that straight line segments can produce the illusion of a curve and helps them recognize and describe number patterns and geometric fundamentals.

Students reproduce the first eleven rows of Pascal's Triangle by recalling number patterns. In this math lesson, students are given a series of patterns to work with in order to reproduce Pascal's Triangle. Students are...

Students identify and explain these vocabulary words: vibration, volume, pitch, particles, tuning forks, waves and matter. They explain that sound travels through gas, liquid and solid. They be

Learners describe the functions of bones in the human body. They describe the make up of a bone. They engage in a series of wonderful hands-on activitiies that reinforce learning of bones and the skeletal system.

Students determine the center of mass of two irregularly shaped objects, determine when the center of mass is inside or outside the boundaries of the object, determine when and/or why an object is stable, balanced, unstable or unbalanced.

Students experiment with pea pods to observe/appreciate the diversity of individuals within a population, and to explain of how dominant and recessive traits, genotypes, and phenotypes help produce variation in a population.

Fourth graders define the states of matter and their properties. They demonstrate the air is matter and observe the effect of molecular motion through these activities.

Students identify living and non-living things and explain the importance of earthworms to the soil. They name some basic facts about earthworms, recognize basic worm vocabulary words and demonstrate vermicomposting techniques.

Students learn three different types of muscles. By building a model of the arm, they learn its basic anatomy and how muscles function in relationship to bones. They perform an experiment on the relationship between muscle size and...

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Young scholars practice creating mixtures out of colored beads.

Students participate in an experiment to help them explain specular and diffusion reflection.

Students explain the physical properties of matter. They, in groups, perform a variety of experiments, each demonstrating a different property of matter. A very nice, hands-on lesson!

Students complete a variety of labs to help them explain how energy affects the changes in states of matter. They also be required to collect and record data, graph data, and apply interpretations of that data.

Learners experiment with solubility and bonding.

Fourth graders create clocks and complete small group activities to represent the six different times zones in the US. Using small paper plate clocks, 4th graders visually demonstrate the differences in these time zones.

Students explore inertia using magic tricks. They participate in demonstrations using tablecloths and dishes, Ken and Barbie, and Wine Bottles.

Students study the concept of periodic motion and relate it to the movement of a pendulum. They discover that the period of a pendulum is dependent on the length of the pendulum and independent of the bob and the amplitude.

Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.

Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

Students, in groups, combine given materials from an everyday kitchen until a chemical reaction occurs and record the reaction time.
