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.

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.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match. Although this is a perception activity, it also demonstrates the difference between mixing colors of light and mixing pigments. Why when mixing pigments does the color darken? How does this differ from mixing colored light? Find out here!

This is a presentation on mixture. It includes descriptions on the different types of mixtures, what makes a mixture, etc. Scroll through to learn more about the mixtures in our everyday lives.

This activity is a laboratory extension where students test and collect data on two kitchen materials in the categories of solubility, saturation, chemical reaction and weights. Thus, giving students opportunity to reinforce skills already learned.

In this activity, students pose several hypotheses for what will happen if you continue heating or supplying energy to the hot and cold planet models (Mercury, Mars, Venus, and Earth) and then test their hypotheses using a spreadsheet based radiation balance model. The activity supports investigation of a real world challenge, experimenting with life support conditions for Mars at an Arctic outpost. The interactive model runs are conducted using a Java applet. This resource includes student worksheets, assessment questions and a teacher's guide. This is Activity B in module 2, Modeling hot and cold planets, of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

This activity is a guided practice and scaffolding activity in which the students learn how to configure electrons of elements and determine the number of valence electrons.

In this activity, candy models are used to demonstrate the features of the Earth, including its internal structure and layers. Students learn why models are essential in Earth science and answer questions about how their candy models do and do not compare with the actual Earth.

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

This activity investigates the molar conversions used in a single replacement reaction between copper and iron.

What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water.
