Exploring Sound Effects
In this NASA Quickbits video, you will learn about the Sound Effects Activity where students at home or at school can learn about the principles of sound and the engineering design process. Students will use the engineering design process to construct a speaker to amplify sound and then they will be challenged to find a solution to reduce the perceived sound volume. We will also highlight NASA Aeronautical Research with the creation of their newest X-Plane the X-59.

Testing a Scientific Explanation of Life Characteristics
With NASA’s Mars 2020 rover, Perseverance, now on its way to Mars to look for signs of past life on the Red Planet, one might be wondering, “how can one search for possible life on another planet?” While it might be easy to recognize life in large objects, it may not be so simple when studying tiny organisms or fossilized materials. In this Quick-Bits video, students are challenged to use the scientific method to observe, hypothesize, and then test possible characteristics of life. In doing so, students and their parents will gain a deeper appreciation for the process by which NASA seeks to answer the age-old question, “are we alone in our Universe?”

Exploring the Story of an Aquatic Habitat
There is a reason that astrobiologists use the presence of water as a prime indicator of habitability. On our planet, life exists in nearly every body of water, from the largest ocean to the smallest puddles. This NASA Quick-bits video explores a wonderfully hands-on section of The Water Wonders activity associated with the storybook “Discoveries at Willow Creek”. These activities and more are found at NASA’s GLOBE Program website: https://www.globe.gov/web/elementary-globe/overview/water.

Exploring Forces of a Falling Object
This NASA Quick-bits video explores forces and motion. Participants are challenged to use the engineering design process to plan, construct, test and analyze a prototype parachute to slow the descent of an egg and minimize the impact when it reaches the floor. Newton’s 2nd and 3rd Laws of Motion are demonstrated in this activity. This activity is part of the Next Gen STEM Commercial Crew Program and can be found at this website https://www.nasa.gov/stem-ed-resources/eggstronaut-parachute-challenge-educator-guide.html.

Make Handprint Art Using Ultraviolet Light
The big idea in this NASA Quick-bit video is that the Sun, our closest star and center of the solar system produces heat and light for the Earth. This video begins with 10 facts about our Sun. Then we watch a video about the relationship between our Sun and the Earth. Participants then learn about two types of energies that Earth receives from the Sun. One that allows us to see and one we can’t see but we can certainly feel its effects if we stay out in the Sun for too long without protecting ourselves. Join in the activity Make Handprint Art Using Ultraviolet Light that demonstrates what happens when we stay out in the sun too long without protecting our skin.

Natural Selection And Adaptations In Bird Beaks
NGSS Disciplinary Core Idea OR NGSS Engineering and Science Practice: MS-LS4-4
Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
NASA continues to study birds by collecting data through satellites that show how weather and climate change is affecting birds and by following eBird to help us understand our bird populations. This NASA Quick-Bits video is designed for students to think critically, explore and discover, and use the inquiry process as they examine bird beaks. Participants will investigate how the shape and structure of beaks affects the type of food that birds are able to eat, describe how different types of bird beaks have adapted to feed on different foods within a specific habitat and learn that birds with beaks that are better adapted will have a better rate of survival.

Summary: “Named after one of the largest constellations in the night sky, …Orion will serve as the exploration vehicle that will carry the crew to [the vicinity of the Moon and Mars], provide emergency abort capability, sustain astronauts during their missions and provide safe re-entry from deep space return velocities” (NASA, 2017). In July 2019, NASA tested Orion’s Launch Abort System [LAS], which is critical for keeping astronauts safe during future Artemis launches. In this Quick-Bits video, students construct and then optimize a representative Orion LAS model in order to balance it around its center of gravity in a process similar to what NASA engineers do when they model and calculate center of gravity for the Orion LAS prior to its integration with the Space Launch System rocket.

Bone Density in Microgravity
NGSS Disciplinary Core Idea OR NGSS Engineering and Science Practice:
Next Generation Science Standards:
- 4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior and reproduction.
- MS-LS1-1. Conduct an investigation to provide evidence that living things are made of cells: either one cell or many different numbers and types of cells.
- MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
- Crosscutting Concepts: Cause and Effect.
- Science and Engineering Practices: Asking questions; planning and carrying out investigations; analyzing and interpreting data; constructing explanations.
Today’s Big Idea is about bone density in microgravity. Learn about an activity where you can test how an impact can affect bones of different densities using a piece of cereal to represent a bone cell. Some bones have more cells which means they have higher density. Disuse or inactivity will lead to a decrease in bone density. Watch how astronauts on the International Space Station use exercise on orbit and dive into the science behind what happens to bones and muscles in microgravity.
