1. Science is the systematic study of nature and how it affects us and our environment.
2. We use scientific knowledge to invent useful devices like light bulbs and computers through technology.
3. A science laboratory provides a place for scientists and students to safely perform experiments, using equipment like Bunsen burners, beakers, and test tubes while following safety precautions.
The document discusses the different branches of science - life science, earth science, and physical science. It provides examples of fields of study and tools used that fall under each branch. These include fields like zoology, geology, and chemistry as well as tools used by scientists working in those fields like microscopes, rock hammers, and beakers. The document instructs the reader to categorize the examples under the appropriate branch and then create a foldable to organize the information.
The document defines science as using observations and experiments to describe and explain the world around us. It discusses how the scientific method involves making observations, developing ideas to explain them, thinking of experiments to test those ideas, predicting the results, and modifying ideas based on what is observed. The document provides examples of different types of scientists such as astronomers, biochemists, botanists, and explains that a scientist conducts experiments to learn. It notes that studies not based on the scientific method, like some advertising claims, are considered pseudoscience rather than real science. Finally, it states that students can also be scientists.

Key terms like traits, adaptations, reproduce, and survive are defined. Examples are given of physical and behavioral adaptations that help plants and animals live in their environments.
Science in Everyday Life (Science Blog #2)Amber Brown
This document outlines ways that everyday objects can be used to teach science concepts from the North Carolina Standard Course of Study. It provides examples of how plants, rocks, liquids, solids, gases, magnetism, electricity, light bulbs, calories, and nutrition can demonstrate first grade and fourth grade science goals and standards. The document encourages looking for science lessons all around that relate to the needs of living things, properties of matter, force and motion, and energy from food.
Here are 3 observations and an inference for each set of animal tracks:
Set 1:
Observations:
1. There are 4 toe prints in each track.
2. The prints form a line with space between each set.
3. The prints are rounded with claw marks.
Inference: Based on the observations, I infer these tracks were made by a dog or wolf.
Set 2:
Observations:
1. There are 3 long toe prints in each track.
2. The prints form a staggered line with one print in front of the other.
3. The prints are elongated with no claw marks.
Inference: Based on the observations, I infer these tracks were
This document discusses physical and behavioral adaptations that help animals survive in the wild. It begins by asking the reader to think about how they dress for winter and describes these behaviors as adaptations. It then defines physical adaptations as body structures like camouflage, mimicry, body coverings, and chemical defenses that help animals find food, defend themselves, and survive. Behavioral adaptations are animals' actions that can be instinctive, like finding shelter or migrating, or learned through experience. Examples of physical and behavioral adaptations are given for different animals and the document concludes by reminding the reader to consider an animal's adaptations when learning about it.

Quantum Mechanics
Natural resources are things that come from nature that are used by humans. They include plants, animals, air, water, soil, rocks and minerals, fossil fuels like coal, crude oil and natural gas, the sun, and wind. Plants provide food, oxygen, clothing materials like cotton, paper and lumber. Animals provide food and materials like leather. Soil is necessary for growing plants and is used to make glass, concrete, bricks and tiles. Rocks and minerals are used for construction, metals that are essential for infrastructure and manufacturing are derived from minerals found in rocks. Fossil fuels are primarily used for energy but also to make plastics and other materials. The sun and wind are renewable energy resources.
This document discusses the parts of a plant and what plants need to grow. It explains that plants need soil, water, sunlight, and air to survive. The document also identifies different parts of a plant, such as roots, stems, leaves, and flowers. It notes that many plant parts, like roots, stems, leaves, and fruits, can be eaten by humans as foods.
Scientific investigations follow a standard process:
1) Ask a question and form a hypothesis to make a prediction about the outcome.
2) Design an experiment to test the hypothesis by manipulating variables and collecting data through observation and measurement.
3) Analyze the results to determine whether the data supports or refutes the original hypothesis.

The document discusses invertebrate animals. It defines invertebrates as animals without a backbone and explains that they are oviparous and can be found living in many environments with different diets. The document then describes some common groups of invertebrates, including jellyfish, annelids/worms, molluscs, and various arthropods such as insects, arachnids and crustaceans. For each group, it provides some key defining characteristics and examples.
The document discusses several constellations visible from Earth, including the Southern Cross, a cross-shaped constellation visible in the southern hemisphere; the Big Dipper, a group of seven bright stars that point to the North Star; and Scorpius, a large constellation shaped like a scorpion that can be seen in the southern sky between June and August. The constellations help indicate directions, planting seasons, and harvesting times.
Seedlings grow from seeds and contain the food needed for the young plant to grow. Flowers produce seeds which start the next generation. Pollination occurs when pollen is transferred between flowers by insects, animals, wind or water, allowing seeds to form. Non-flowering plants grow directly from seeds into trees or shrubs without producing flowers.
1) All animals, including humans, have certain needs that must be met in order to survive, including food, water, oxygen, shelter, and space.
2) The area where an animal lives and meets its needs is called its habitat. Animals need different amounts of space for their habitat depending on the species.
3) The main needs that must be met for animals and humans to survive are food, water, oxygen, shelter, and space or habitat. Without meeting these basic needs, the animal will die.
The document discusses food chains and how energy passes from producers to consumers. It explains that plants get energy from photosynthesis, and are eaten by herbivores as primary consumers. Carnivores that eat herbivores are secondary consumers, and carnivores that eat other carnivores are tertiary consumers. Omnivores eat both plants and animals. Decomposers break down dead matter and release nutrients back into the food chain. The document provides examples of food chains and online resources for students to learn more.
Possible Anthropogenic Contributions to the LAMP-observed Surficial Icy Regol...Sérgio Sacani
This work assesses the potential of midsized and large human landing systems to deliver water from their exhaust
plumes to cold traps within lunar polar craters. It has been estimated that a total of between 2 and 60 T of surficial
water was sensed by the Lunar Reconnaissance Orbiter Lyman Alpha Mapping Project on the floors of the larger
permanently shadowed south polar craters. This intrinsic surficial water sensed in the far-ultraviolet is thought to be
in the form of a 0.3%–2% icy regolith in the top few hundred nanometers of the surface. We find that the six past
Apollo Lunar Module midlatitude landings could contribute no more than 0.36 T of water mass to this existing,
intrinsic surficial water in permanently shadowed regions (PSRs). However, we find that the Starship landing
plume has the potential, in some cases, to deliver over 10 T of water to the PSRs, which is a substantial fraction
(possibly >20%) of the existing intrinsic surficial water mass. This anthropogenic contribution could possibly
overlay and mix with the naturally occurring icy regolith at the uppermost surface. A possible consequence is that
the origin of the intrinsic surficial icy regolith, which is still undetermined, could be lost as it mixes with the
extrinsic anthropogenic contribution. We suggest that existing and future orbital and landed assets be used to
examine the effect of polar landers on the cold traps within PSRs
In recent years, the growth of scientific data and the increasing need for data sharing and collaboration in the field of environmental chemistry has led to the creation of various software and databases that facilitate research and development into the safety and toxicity of chemicals. The US-EPA Center for Computational Toxicology and Exposure has been developing software and databases that serve the chemistry community for many years. This presentation will focus on several web-based software applications which have been developed at the USEPA and made available to the community. While the primary software application from the Center is the CompTox Chemicals Dashboard which provides access to data for >1.2 million chemicals (https://comptox.epa.gov/dashboard), almost a dozen proof-of-concept applications have been built serving various capabilities. The publicly accessible proof-of-concept Cheminformatics Modules (https://www.epa.gov/chemicalresearch/cheminformatics) provides access to multiple applications in development allowing for hazard comparison for sets of chemicals, structure-substructure-similarity searching, structure alerts and batch QSAR prediction of both physicochemical and toxicity endpoints. A number of other applications, presently in development but not publicly accessible will also be discussed. These include AMOS, the database of Analytical Methods and Open Spectra.
Analytical methods can vary in nature from detailed regulatory methods to more summary in nature. Regulatory method documents can include details of analytes which can be studied, supported matrices, reagents, methodological details, statistical performance, interlaboratory validation and other details. Summary methods provide a general overview of reagents, instrumentation and commonly a short list of analytes. Regulatory bodies including the US Environmental Protection Agency (US-EPA), US Geological Survey (USGS), US Department of Agriculture (USDA) and others provide detailed analytical methods and collections of summary methods from the agrochemical industry, such as the US-EPA Environmental Chemistry Methods (https://www.epa.gov/pesticide-analytical-methods/environmental-chemistry-methods-ecm). Instrument vendors also provide access to many hundreds of application notes which can be considered as summary methods. AMOS presently contains >4,500 methods integrated to their chemical structures and > 230,000 public domain mass spectral data. AMOS allows for filtering of methods based on analyte, chemical class, method source and other related metadata. AMOS is an important facet of the developing Non-Targeted Analysis WebApp presently also in development at the EPA.
This presentation will provide an overview of existing publicly accessible Dashboards and work in progress to support analysis of pesticides, veterinary drug residues, and other chemicals in food, animal feed, and environmental samples.
The cryptoterrestrial hypothesis: A case for scientific openness to a conceal...Sérgio Sacani
Recent years have seen increasing public attention and indeed concern regarding Unidentified
Anomalous Phenomena (UAP). Hypotheses for such phenomena tend to fall into two classes: a
conventional terrestrial explanation (e.g., human-made technology), or an extraterrestrial explanation
(i.e., advanced civilizations from elsewhere in the cosmos). However, there is also a third minority
class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of
the universe. This is the ultraterrestrial hypothesis, which includes as a subset the “cryptoterrestrial”
hypothesis, namely the notion that UAP may reflect activities of intelligent beings concealed in stealth
here on Earth (e.g., underground), and/or its near environs (e.g., the moon), and/or even “walking
among us” (e.g., passing as humans). Although this idea is likely to be regarded sceptically by most
scientists, such is the nature of some UAP that we argue this possibility should not be summarily
dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness.
A Strong He II λ1640 Emitter with an Extremely Blue UV Spectral Slope at z=8....Sérgio Sacani
Cosmic hydrogen reionization and cosmic production of the first metals are major phase transitions of the Universe
occurring during the first billion years after the Big Bang; however, these are still underexplored observationally.
Using the JWST/NIRSpec prism spectroscopy, we report the discovery of a sub-L* galaxy at zspec =
8.1623 ± 0.0007, dubbed RX J2129–z8He II, via the detection of a series of strong rest-frame UV/optical nebular
emission lines and the clear Lyman break. RX J2129–z8He II shows a pronounced UV continuum with an
extremely steep (i.e., blue) spectral slope of 2.53 0.07
0.06 b = - -
+ , the steepest among all spectroscopically confirmed
galaxies at zspec 7, in support of its very hard ionizing spectrum that could lead to a significant leakage of its
ionizing flux. Therefore, RX J2129–z8He II is representative of the key galaxy population driving the cosmic
reionization. More importantly, we detect a strong He II λ1640 emission line in its spectrum, one of the highest
redshifts at which such a line is robustly detected. Its high rest-frame equivalent width (EW = 21 ± 4 Å) and
extreme flux ratios with respect to UV metal and Balmer lines raise the possibility that part of RX J2129–z8He II’s
stellar population could be Pop III (Pop III)-like. Through careful photoionization modeling, we show that the
physically calibrated phenomenological models of the ionizing spectra of Pop III stars with strong mass loss can
successfully reproduce the emission line flux ratios observed in RX J2129–z8He II. Assuming the Eddington limit,
the total mass of the Pop III stars within this system is estimated to be 7.8 ± 1.4 × 105 Me. To date, this galaxy
presents the most compelling case in the early Universe where trace Pop III stars might coexist with metal-enriched
populations.

All-domain Anomaly Resolution Office Supplement to Oak Ridge National Laborat...Sérgio Sacani
In 2022, The All-domain Anomaly Resolution Office (AARO) contracted with Oak Ridge
National Laboratory (ORNL) to conduct materials testing on a magnesium (Mg) alloy specimen.
This specimen has been publicly alleged to be a component recovered from a crashed
extraterrestrial vehicle in 1947, and purportedly exhibits extraordinary properties, such as
functioning as a terahertz waveguide to generate antigravity capabilities. In April 2024, ORNL
produced a summary of findings documenting the laboratory’s methodology to assess this
specimen’s elemental and structural characteristics, available on AARO’s website.
ORNL assessed this specimen to be terrestrial in origin and that it does not meet the theoretical
requirements to function as a terahertz (THz) waveguide. AARO concurs with ORNL’s
assessment and provides this supplementary material to add historical context to account for its
likely origin. The specimen’s characteristics are consistent with Mg alloy research and
development projects and experimental manufacturing methods in the mid-20th century.
Lunar Mobility Drivers and Needs - ArtemisSérgio Sacani
NASA’s new campaign of lunar exploration will see astronauts visiting sites of scientific or strategic
interest across the lunar surface, with a particular focus on the lunar South Pole region.[1] After landing
crew and cargo at these destinations, local mobility around landing sites will be key to movement of
cargo, logistics, science payloads, and more to maximize exploration returns.
NASA’s Moon to Mars Architecture Definition Document (ADD)[2] articulates the work needed to achieve
the agency’s human lunar exploration objectives by decomposing needs into use cases and functions.
Ongoing analysis of lunar exploration needs reveals demands that will drive future concepts and elements.
Recent analysis of integrated surface operations has shown that the transportation of cargo on the
surface from points of delivery to points of use will be particularly important. Exploration systems will
often need to support deployment of cargo in close proximity to other surface infrastructure. This cargo
can range from the crew logistics and consumables described in the 2023 “Lunar Logistics Drivers and
Needs” white paper,[3] to science and technology demonstrations, to large-scale infrastructure that
requires precision relocation.

Complementary interstellar detections from the heliotailSérgio Sacani
The heliosphere is a protective shield around the solar system created by the Sun’s interaction with the local interstellar medium (LISM) through the solar wind, transients, and interplanetary magnetic field. The shape of the heliosphere is directly linked with interactions with the surrounding LISM, in turn affecting the space environment within the heliosphere. Understanding the shape of the heliosphere, the LISM properties, and their interactions is critical for understanding the impacts within the solar system and for understanding other astrospheres. Understanding the shape of the heliosphere requires an understanding of the heliotail, as the shape is highly dependent upon the heliotail and its LISM interactions. The heliotail additionally presents an opportunity for more direct in situ measurement of interstellar particles from within the heliosphere, given the likelihood of magnetic reconnection and turbulent mixing between the LISM and the heliotail. Measurements in the heliotail should be made of pickup ions, energetic neutral atoms, low energy neutrals, and cosmic rays, as well as interstellar ions that may be injected into the heliosphere through processes such as magnetic reconnection, which can create a direct magnetic link from the LISM into the heliosphere. The Interstellar Probe mission is an ideal opportunity for measurement either along a trajectory passing through the heliotail, via the flank, or by use of a pair of spacecraft that explore the heliosphere both tailward and noseward to yield a more complete picture of the shape of the heliosphere and to help us better understand its interactions with the LISM.
