This is the project information for students to complete an original Chemistry experiment. It can be adapted to other areas in science. It guides students through the process and includes links to additional materials used.

Design and engineer a mechanical device that is powered by hydraulic (syringe and water) that includes levers and moving parts that will propel a ping pong ball to complete the 2 levels of the “Hoop Shoot Challenge”.

In this video from Outdoor Nevada, learn about the habitat, diet, and defense mechanisms of horned lizards.

In this video segment from PEEP and the Big Wide World, children experiment with cardboard and build a house for their stuffed animals.

This article reprints and links to informational text about the art and science of igloos. Versions are available for students in grades K-1, 2-3 and 4-5. Related science and literacy activities are included.

Students will construct CD hovercraft and apply Newton's laws of motion to make them work. They will also investigate how hovercraft reduce friction; learn how the technology is used in training astronauts for space missions; and design their own hovercraft competitions.

Students will complete a data table using authentic tide predictions from the National Oceanic and Atmospheric Administration. Next, students will use their data table to create a line graph that will show the relationship between the tidal range and moon phases. Lastly, students will analyze their graph to explain how the occurrence of ocean tides is related to the moon's phases. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

This problem based learning (PBL) activity allows students to become educated on how excess waste can harm the environment. This activity then has the students form a plan on how their school can limit trash output in their cafeteria, and then sending a letter to their principle describing their plan.

In this unit, students start by observing a perplexing phenomenon. When a sewing needle taped to a cone is dragged over the surface of a plastic disc that is spun underneath it, it produces voices and musical notes. This leads students to start wondering about other sound-related phenomena, which in turn leads to wealth of new questions about 1) What causes different sounds? 2) What is traveling from a sound source to our ears? 3) How do we hear and why do we hear things differently in different places? and 4) How do electronic devices (digital sound sources) produce and detect sounds?

This narrated animation from Interactive NOVA: "The Secret of Life" illustrates DNA replication.

This video segment adapted from NOVA describes the emergence of life on the islands of Hawaii from a barren volcanic platform under the ocean waves to the rich explosion of life that covers the many climate zones of the islands today.

In this video segment adapted from NOVA, dramatic footage of avalanches and animations of ice crystals illustrate how a layer of weakly-bonded snow can contribute to a devastating avalanche.

Every living thing must be able to reproduce and make offspring. Most of us are familiar with how humans and mammals make babies, but do all creatures reproduce in the same way? Do insects, like the beetle, give birth to little insects? Also in: French | Spanish

In this video segment adapted from NOVA, scientists use computer simulations to explore the question of how supercell thunderstorms produce tornadoes.

This video segment adapted from FETCH! shows contestants experimenting with different materials to see which is the best insulator and thus best able to keep the lemonade at their stand cool for customers.

This first-grade unit on light starts with students exploring how many shapes they can see on different pieces of paper at various locations around their classroom when the lights are turned off. They are surprised to find that some of the shapes are not visible in these conditions. This leads students to start wondering about other phenomena related to seeing in the dark, which in turn leads to new questions and design problems related to how they can make their room completely dark.

Students investigate how sea levels might rise when ice sheets and ice caps melt. By constructing a pair of models, students can observe the effects of ice melt in two different situations.

In this lesson, the students will learn that plants need water, air, nutrients, and sunlight to grow. This lesson results from a collaboration between the Alabama State Department of Education and ASTA. **This lesson can be taught over a three to five day period. Simply repeat the steps as the students will become more knowledgeable of the target.

Aaron and Justin investigate which sunscreen best keeps out harmful ultraviolet rays from the Sun, in this video from DragonflyTV.

In this lesson, students will conduct an experiment to compare similarities and differences with wind and water erosion. Students will create a narrative story describing a particular rock formation based on evidence in the rock patterns, including an estimated time frame, plants and animals that may have been living in the environment, and the type of erosion that formed their rock formation. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
