Students will create their own solar ovens to bake s'mores on for a STEM project relating to the Idaho National Laboratory's solar project. This is a fun STEM activity for students to use the engineering design process and to give them an idea of what the Department of Energy's researchers do at Idaho's National Laboratory.

In this video segment adapted from ZOOM, cast members assemble a solar still and make fresh water from saltwater, demonstrating two steps of the water cycle, evaporation and condensation.
Investigate what makes something soluble by exploring the effects of intermolecular attractions …
Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution, allowing you to experiment with how external factors, such as heat, can affect a substance's solubility.

Water is essential for life as we know it, due in part to its ability to dissolve a wide range of substances. In fact, most chemical reactions occur in a dissolved state. This pathway provides resources regarding how water is able to act as a solvent.
This activity is a small-group activity that makes students learn the subject …
This activity is a small-group activity that makes students learn the subject matter of aqueous solutions (colloids, suspensions) and phase changes by writing a children's book. Learning by teaching.

This video segment, adapted from ZOOM, explores how sound waves travel differently through solids than through air, in this case, a metal clothes hanger.

What happens when an excited atom emits a photon? What can we deduce about that atom based on the photons it can emit? A series of interactive models allows you to examine how the energy levels the electrons of an atom occupy affect the types of photons that can be emitted. Use a digital spectrometer to record which wavelengths certain atoms will emit, and then use this knowledge to compare and identify types of atoms. Students will be abe to:
This video segment adapted from Shedding Light on Science uses historical illustrations …
This video segment adapted from Shedding Light on Science uses historical illustrations and everyday examples to show that light has a speed and does not travel instantaneously.
This activity allows students to brainstorm investigable questions, conduct an experiment, and …
This activity allows students to brainstorm investigable questions, conduct an experiment, and communicate the results related to our invertebrate animal study; specifically sponges and absorption. (Lesson is based on an original activity from "Porifera's Porosity", Holt Science and Technology - Animals, Holt, Rinehart, and Winston 2002, pages 50-51.)
In this mini-lab students will use chromatography to compare the mobile phase …
In this mini-lab students will use chromatography to compare the mobile phase and the stationary phases of different inks used in marking pens. They will also determine the polarity of the solvents and inks. Finally, the students will use their calculated information to solve a crime.
After using the historical development of the Standard Model to develop introductory …
After using the historical development of the Standard Model to develop introductory understanding, students link to OPAL and DELPHI data archives from CERN to identify and study the tracks from elementary particles.
This activity is used to introduce the different properties of states of …
This activity is used to introduce the different properties of states of matter, by testing an unknown substance with household materials to determine which state of matter most closely resembles the material. It also can invole data collection, reasoning, grph making, and presentation of findings.
Students act as chemical engineers and use LEGO® MINDSTORMS® NXT robotics to …
Students act as chemical engineers and use LEGO® MINDSTORMS® NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and temperature. Students measure the temperature of water in its solid state (ice) as it is melted and then evaporated.
