Technically tasty
Virtual reality (VR) has expanded people's ability to experience visual and auditory sensations in virtual worlds. What about our other senses? Learn how chemical-detection capabilities of the tongue allow us to taste cake as being sweet and lemonade as being sour. Explore how scientists used this understanding to develop taste-mimicking VR technology, all while answering questions about how this tasty research might one day help people.
Observations vs. Experiments: Two types of research design
In this lesson, students will compare and contrast observational studies with experimental studies and practice identifying the study types from provided examples. Then, they will apply that knowledge to two studies outlined in Science News articles. As an optional assignment, students will be asked to create an example of a possible study.
Making use of nature’s designs
New discoveries about the natural world can inspire the design of human-made objects. In this activity, students will learn about how the overlapping feathers on birds’ wings prompted engineers to reimagine the design of aircraft wings. Students will explain how this is an example of bioinspired design and then create their own bioinspired designs.
Covering Carbon
Climate scientists are continuing to develop new methods to sequester atmospheric carbon to help curb climate change. In this activity, students will learn about how carbon can be sequestered through the burial of organic material and review the carbon cycle. Students will practice using percent by mass concepts and dimensional analysis to calculate how much wood would need to be buried to achieve climate targets by the year 2060. As an optional extension, students may then develop a plan to mitigate greenhouse gas production that utilizes biomass burying techniques.
Dune-inspired spacesuit
Science fiction sometimes inspires real-world innovation. Future spacesuits may filter urine into drinkable water, allowing astronauts to wear those suits for longer tasks. Learn how researchers propose to make fantasy a reality while answering questions about the filtration techniques and how spacesuits are needed to handle the constraints of space.
Springtail research design and data analysis
Scientists have discovered that Dicyrtomina minuta, a species of globular springtail, can perform the fastest backflip of any animal on Earth. Use this discussion to have students review how the research team studied springtail backflips by analyzing high-speed footage.
Then, in this related activity by DataClassroom, have students analyze graphs of the springtail research data to learn about the linear velocity, angular velocity, linear acceleration and rotational acceleration of springtail flips using this Stacked Graphs and Biophysics with Spring-Loaded Arthropods activity. Create a free account to view the student-facing dataset and activity within the DataClassroom web application. View the teacher answer key here.

Build It: Climate Design Challenge
As global temperatures increase we’ll need to change how we design our buildings. Climate responsive architecture includes buildings that are designed with the regional climate in mind. In this activity, students will design a building that stays at a safe and comfortable temperature throughout the day. In their designs, students will have to consider the Sun’s movement in the sky and their buildings’ materials and shapes. Students will model and test their designs before learning about a new idea scientists have for climate responsive architecture.
Cats are liquid
"Cats are liquid." You may have heard this playful saying before. Cats earn a reputation for oozing in and out of some tight spots. But lately, some scientists started wondering whether they’d fit through an opening of any size. Learn how scientists have developed controlled in-home experiments to address such questions scientifically. Answer questions about independent and dependent variables and compare two similar experiments in terms of experimental design.
Arthropod Olympics
A recent study found that a species of globular springtail can perform the fastest backflip of any animal on Earth. In this activity, students will research another Olympics-worthy arthropod competitor and describe how they’d measure performance in their imagined sports event.
Investigating phenomena with SEPs
To investigate why some meteors create persistent trails, scientists filmed the New Mexico sky for two years, recording streaks of light. Use shooting stars as an example phenomenon to generate student interest, wonder and questions. Then, have students explore how this phenomenon was studied using Science and Engineering Practices, while evaluating the study’s design, limitations and possibilities for future research. Finally, have students search for another phenomenon that interests them and begin asking questions about it.
Egyptian hydraulics: Does this idea hold water?
How did the ancient Egyptians build the pyramids? It's an age-old mystery. A new study points to hydraulic engineering. But does this idea really hold water? Some experts in the field argue against new evidence being provided to support such claims. Learn how researchers use evidence to support claims while discussing the value of healthy skepticism in science.
Overcooked & Outplayed
In this study, humans and AI worked together to score the win. But it’s the human partners that got played. Learn how some methods for training AI can also teach AI to influence human behavior, then answer questions about the potential implications of a future world in which AI sways human behavior.
