With this resource, students will use their senses and scientific equipment to make observations and then use the observations to make predictions about density.

In this activity, students will compare the desities of various objects and solve a problem of which kind of candy bar is the best value for the purchase.

With this resource, students will learn about the true size and structure of an atom. In groups of six, students will be assigned the role of either a proton, neuron or electron and demonstrate the position of these atomic particles in a helium atom.

This activity will gives a way to estimate the mass and volume of a gas like air. What kind of container can we use to hold the air? A beaker? A graduated cylinder? It would just leak out, and they are probably already filled with air, so these containers wouldn't work too well. We will use a balloon, since it is made just for this purpose!

In this activity, students will demonstrate the effect that temperature has on particle motion and volume.

This resource explains the different states of matter and provides interative questions to test students knowledge.

In this activity, students will answer the question, "How will differences in temperature change the rate at which food coloring spreads throughout water?"

Scientists describe all matter on Earth as having constant molecule motion. Molecules in a gas are moving rapidly. Molecules in a liquid move quickly but not as fast as a gas. The molecules in a solid typically vibrate in place. Using a microscope, students should be able to observe random motion as they do this activity.

In this interactive lesson, students rotate to different sports activity stations to determine if a push or a pull or both are being used for that sport. Students record their observations by writing a simple phrase to explain the push or pull force they used. At the end of the rotations, students compile their data onto a class tally graph. Extension activities include involving the Olympics and Para-Olympics and their family members. Probing questions that include determining if the age of the thrower affects force and distance and assessment extend and complete the lesson.

In this lesson, students will estimate measures using common benchmarks for units in the metric and customary system. Students will convert units in the same system.

With this resource, students will sketch pictures of actual protists including, paramecium, euglena, amoeba and algae.

With this resource, students will discover information about the microorganisms that cause different diseases.

In this lesson, students use various models to represent multiplication and division of fractions.

In this lesson, students will learn about the laws of motion and force and demonstrate how difference in the amount of force causes changes in speed or direction of objects.

In this lesson, students will identify angles found in the real world and classify and draw them. Then they will create a book where they will record angles found within their environment.

In this lesson, students will think about the uses of rocks in the world around them. Students will look and write about what they find in the "Mystery Rock Boxes". Students will learn about salt, sand, granite, limestone, and pumice.

In this lesson, students play a series of games to help them learn the names of classmates. They will also answer questions about themselves so that their classmates can learn more about them. Students can compare themselves to other classmates and identify similarities.
