This activity is an inquiry lesson where students learn how to accurately read a thermometer and then set up an investigation to compare the temperatures of different materials or locations.

Marie Hartford's class of 5th grade scientists learn about the importance of water quality and its benefits to wildlife and the environment. Within the narrow confines of pH necessary for their tank of red-legged frogs, students use a combination of pond and tap water to keep the tank healthy, using their collected data to make the decision on the proportion between the two.

Learn about a job as a chemist from the ChemHealthWeb site of the National Institute of General Medical Sciences. See how people from all walks of life, from different countries and cultures, and with very different backgrounds had an interest in chemistry and chose it as their career.

What can you do with chemistry skills? A lot of things, it turns out! Learn about the diversity of careers available to people interested in chemistry.

Monitor the temperature of a melting ice cube and use temperature probes to electronically plot the data on graphs. Investigate what temperature the ice is as it melts in addition to monitoring the temperature of liquid the ice is submerged in.

Metric Conversion at a Glance is an easy way to teach students how to convert one metric measurement into another without the use of fractions. It works for one, two and three dimensions length, area and volume.

Learn about an important physics experiment that uses an invention that manipulates light in this interactive activity adapted from NASA.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Indoor microbes can release harmful volatile organic compounds (VOCs), but how environmental factors and microbial community composition impact microbial VOC emissions is unclear. To learn more, researchers recently subjected drywall and carpet to different equilibrium relative humidity levels and quantified microbial communities and microbial VOC emissions. Fungus grew in dusty carpet when the humidity was >75% and in inoculated painted drywall when the humidity was >85%. The dust sample collection site and the material type significantly affected the fungal and bacterial species compositions. In dusty carpet, increased humidity was associated with decreased microbial species diversity. Abundant VOCs were likely released from the materials and dust themselves, but some microbial VOCs, such as C₁₀10H₁₆H⁺ (monoterpenes) and C₂H₆SH⁺ (dimethyl sulfide and ethanethiol), were released from microbes that grew in dusty carpet. At 95% humidity, dusty carpet produced 5..."

This group learning activity involves students in an engaging review of concepts of microbiology. The review is set up as a power point presentation in the style of the "Jeopardy" gameshow where students groups compete against each other to answer review questions.

In this video from DragonflyTV, Tiana and Sammy measure, record, and analyze the results of a drop box test to find out how everyday items behave in microgravity.

How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner. Used in conjuncture with the rest of the Exploratorium's Skateboard Science website, this activity and others explore the physics of skateboard tricks.

In this geology activity, students investigate the physical property of mineral cleavage by physically trying to break down a block of halite and describing the results. This lab addresses many misunderstandings non-majors have about the physical properties of minerals and includes a brief write up of their conclusions.

This activity is a lab investigation in which students make mass/volume measurements of several samples of the same mineral to determine the mineral's density. Students graph their data and make the connection between their qualitative understanding of what density is and the mathematical/graphical representation of density.

This module introduces students to minerals, crystals, and gems by using pictures and discussions of some of the extraordinary specimens residing in the collections of the Smithsonian Institution. It includes three lessons in which they draw pictures of specimens, grow their own crystals of magnesium sulfate, and perform a scavenger hunt in which they look for minerals in commonly used objects and products.

Again- this is activity that will set the stage for enriching the understanding of the nature of molecular motion and the affect of temperature on its rate as the students allow crystals to diffuse toward each other in a petri dish and form a precipitate.

Students simulate operating an iron mine, from choosing property to writing an environmental impact statement to setting up the mining operation. Chocolate chip cookies (with the chocolate chips representing iron ore) are used for this experiment. Students are challenged to operate the most profitable and environmentally sound mine they can.
