In this lesson, students will differentiate matter into pure substances (elements and compounds) and mixtures on a basic molecular level. Students will use hands-on card sorting to create a rule for sorting matter. The definitions of pure substance, mixture, element, and compound will be introduced.

In this lesson, students will look at the different layers of the atmosphere to determine how the atmosphere helps sustain life on Earth. Students will model the layers of the atmosphere through an interactive lab that looks at characteristics of the atmosphere by analyzing the atmospheric temperature profile and the special features that can be found in each layer.

In this lesson, students become scientists who are studying the components of a Bald Eagle's diet. They will collect data by pulling prey chips from an envelope and recording data. They then graph and draw conclusions about what an eagle eats based in their research data and share their conclusions with the class.

In this lesson, students will collect, analyze, and interpret data to develop an understanding of how the speeds of sound and electromagnetic waves change through different mediums.

In this lesson, students discover body system interactions and how the organ systems work together to maintain homeostasis.

In this lesson, students will conduct several investigations to help them to understand the differences between chemical and physical changes. Students will record investigative observations and use their observations to provide evidence that a physical or a chemical change has occurred.

In this lesson, students will be introduced to climate change caused by greenhouse gases and participate in a simulation of the carbon cycle. Students will develop an understanding of how the movement of carbon atoms can contribute to climate change. Students will collect and analyze data on the movement of carbon atoms through the carbon cycle.

This video discusses the three states of matter and the effect when heat is applied to matter and causes a change in phase.

In this lesson, students will identify methods of classification used for living things by sorting and classifying everyday objects, exploring objects through a digital scavenger hunt, creating a graphic organizer, and through collaborative engagement. Students will understand that all organisms are classified based on shared characteristics.

Students will collect data through a simulation game on deforestation and be able to describe how humans have impacted a simulated forest. Students will also learn about subsistence farming and its role in rain forest (primary) forest deforestation.

This video illustrates how density is calculated and describes how the density of water can be used for comparison of density of other substances.

In this lesson, students will predict, investigate, observe, and report on the effects that pH, concentration, and temperature have on catalase enzyme reactions. Students will conduct an experiment in which they will alter the pH, concentration, and temperature of the environment in which enzyme reactions are taking place.

In this lesson, students create a model that is analogous to a cell. They will use a predetermined model to associate cell function to structure and will discuss the limitations of the models used in the investigation. They will communicate their work and then evaluate the work of their peers in a given context.

In this lesson, students will rotate through six stations in order to gain background knowledge about jet streams and ocean currents. The students will answer questions at each station to elaborate their understanding of jet streams and ocean currents and how they affect local weather.
