Jake's dewpoint experiment!!! copy
Jake conducted an experiment to determine the dew point temperature required for dew to form on a glass. Over seven days, he researched dew points, developed a hypothesis and procedure, and conducted three trials by leaving a glass outside overnight on nights with different dew points. His hypothesis that dew would form when the dew point was around 62°F and relative humidity was 81% was supported. He found dew formed when the temperature was close to the dew point and relative humidity was high, between 84-100%.
Dry ice labs 10.21
The document describes a series of experiments using dry ice conducted by Grade 5 students. Dry ice is the solid form of carbon dioxide and goes directly from solid to gas through sublimation. In the first experiment, bubbles were observed in a fish tank when dry ice was added. Later experiments involved adding dry ice to apple juice, balloons, film canisters and beakers of hot water. Observations were made such as the apple juice becoming fizzy, balloons inflating, and carbon dioxide gas rising from the beakers. The experiments demonstrated dry ice's sublimation and how carbon dioxide is denser than air.
Mpemba Effect
The document summarizes the Mpemba effect, where warmer water sometimes freezes faster than colder water. It describes the effect's history, proposed explanations, and variables that affect outcomes. These include freezing method, definition of "frozen," container properties, and temperature measurement. The authors conducted an experiment demonstrating the effect and found the initially warmer samples froze first. While insulation from early frost formation was initially proposed as the cause, videos suggest it may not fully explain the phenomenon. The causes remain unclear and an area of ongoing research.
Why and how hot water freezes faster than cold water
Hot water can freeze faster than cold water due to differences in air content. When water is heated, it absorbs less air and reaches freezing temperature in a de-aerated state. Cold water absorbs more air and thus contains more air bubbles during freezing. These air bubbles act as insulators, slowing the freezing of cold water compared to hot water which contains fewer bubbles. Experiments support this, showing hot water ice containing fewer bubbles and melting faster.
STREAM TEAM
The document discusses water quality testing at the Greenbelt near the Marshall School. Ms. Buck's 8th grade Earth Science class and the 4-H Stream Team, with assistance from Penn State Cooperative Extension, examined the water quality. Their findings and results are not detailed in the provided text.
Weather
Weather refers to the state of the atmosphere at a specific time and place and is affected by several factors. Key factors that influence weather include air temperature, wind, humidity, clouds, precipitation, air masses, and fronts. Different types of clouds like cirrus, cumulus and stratus form at different altitudes. Precipitation falls as rain, sleet, snow or hail depending on air temperature. Severe weather events like thunderstorms, tornadoes, hurricanes and blizzards can occur and safety watches and warnings are issued. Weather is forecast using data collected from the upper atmosphere and Earth's surface.
Weather
Weather refers to the current state of the atmosphere. Key factors that influence weather include temperature, air pressure, wind, and water in the atmosphere. Global wind patterns are driven by uneven heating of the Earth's surface by the sun, which causes warm air to rise at the equator and flow toward the poles.

GES 102 - PHOTOSYNTHESIS LAB
This week you will investigate the effect of light intensity on the rate of photosynthesis in
spinach leaves. Fresh spinach bought in the store is green, and the leaves still have the
ability to do photosynthesis. Photosynthesis produces carbohydrates and oxygen and we
will use the rate of oxygen production as an indicator of how quickly the spinach leaves
actually do photosynthesis.
You will use a hole punch to make a number of small disks of spinach. These disks float
when they contain oxygen from photosynthesis. By applying vacuum to the small spinach
disks, the oxygen is forced out, and they sink. When you then place the disks in a
transparent cup with water, and expose them to light, they will produce oxygen and
eventually float. The time it takes the small disks to float is a measure of photosynthesis,
and you will test the effect of different light intensities on the floatation time.
Background:
In your first lab this semester you investigated how the UV portion of sunlight was able
to cause harm to living cells, which is not so surprising since this shorter wavelength
carry enough energy to damage the cell’s DNA. In this week’s lab we will instead use the
portion of radiation from the sun that we call daylight (380-780 nm), plenty of which
makes it down to the earth’s surface. Our eyes are sensitive to this portion of the
spectrum, and it’s also the portion plants use for photosynthesis.
The process of photosynthesis can be simplified as:
CO2 + H2O sugar + O2.
It is really divided up into two sets of reactions, the Light Reaction and the Calvin
Cycle. In the Light Reaction the plant cells use chlorophyll to capture some of the energy
in sunlight. When sunlight hits a chlorophyll molecule, electrons in the chlorophyll
GES 102 Lab #5 Spring 2015
21
molecule are excited, they ‘spin’ faster because of the absorbed energy. These excited
electrons are passed on down the line and chlorophyll will take a continuous supply of
new electrons from H2O which is broken down, producing O2. The energy in the excited
electrons is eventually used to produce two high energy molecules, called ATP and
NADPH. In the next step, the Calvin Cycle, the energy contained in ATP and NADPH is
used to help take CO2 (carbon dioxide) from the air and manufacture sugar.
Spinach plants normally get their CO2 from the air, through small openings on the
underside of their leaves, called stomata. In our experiment some sodium bicarbonate
(NaHCO3) will be added to the water, and provide the carbon needed for the small
spinach disks to do photosynthesis. The O2 produced will be trapped inside the spinach
disks and increase their buoyancy until they float.
Alongside photosynthesis, the plants also do cellular respiration. They certainly are
autotrophs and can produce their own “food”, the sugar. ...
Ii matter
This document provides information about the three states of matter - solids, liquids, and gases. It includes experiments and questions to help students understand the key differences between the states. The document explains that in solids, liquids, and gases, particles are arranged differently. In solids, particles vibrate in fixed positions; in liquids, they slide over one another but stay close together; and in gases, particles move rapidly and are far apart. Heating causes particles to vibrate more, which can cause changes between the states of matter. The concept of density is also introduced, which explains why objects with different compositions can have different masses but the same volume.
3.3 Understanding Pressure And Atmospheric Pressure
The document describes a hands-on activity to help students understand atmospheric pressure through six experiment stations. Students are divided into groups that rotate between the stations. Each station has an activity and worksheet to complete. The activities demonstrate concepts like suction, the effect of surface area on lifting force, and how air pressure prevents water from spilling out of an inverted glass. The goal is for students to observe these phenomena and understand that atmospheric pressure is caused by air molecule collisions exerting force on surfaces.
Experiment powerpoint
The document outlines the objectives and activities of a science session. The objectives are for participants to be able to: identify process skills in developing science ideas like experimenting; perform experimental activities using different variables; and explain the effect of controlled variables, independent variables, and dependent variables in experiments. The document then provides an example experimental design on determining what makes an egg float in water. It includes the problem, hypothesis, materials, procedure, observation, and conclusion.
Sweat
This document describes an experiment that models how the human body regulates temperature through sweating. The experiment uses clay jugs filled with hot water to represent the body. One jug is covered with a plastic bag while the other is uncovered. Temperature and humidity sensors monitor changes over time. Covering the jug prevents evaporation, causing its temperature to rise more than the uncovered jug. This demonstrates how sweating and evaporation cool the body during fever by increasing heat dissipation. Maintaining this process prevents overheating, though it can lead to dehydration if water is not replaced.

Introduction to Science
This document provides an introduction to science class for year 9 students, outlining safety rules and procedures for the laboratory. It describes the necessary equipment, basic skills like measuring and graphing data, and examples of experiments involving using a Bunsen burner and observing chemical reactions. The goal is for students to learn foundational scientific concepts and techniques.
Science experiments.
1. The document provides instructions and explanations for 6 hands-on experiments about vision and light. The experiments demonstrate principles like refraction, total internal reflection, and how these principles allow vision and the formation of rainbows.
2. Key experiments include using a glass of water to make a coin appear to "disappear" due to refraction, as well as using a water-filled bottle to demonstrate how total internal reflection allows light to travel along the stream of water, simulating fiber optics.
3. By setting up mirrors and a bowl of water, another experiment shows how refraction of sunlight through water can form a rainbow on a wall, simulating the optical properties of a prism. The hands-
Power point science
The student conducted an experiment to determine which materials provide the best insulation and which areas cause ice cubes to melt the fastest. For the insulation part, ice cubes were wrapped in cotton, foil, plastic wrap, and fabric or left unwrapped as a control. For the area test, ice cubes were placed on a radiator, open window sill, closed window sill, and table. The ice cubes were measured after 10-5 minutes to analyze melting. Results were recorded in line graphs. The experiment aimed to identify the best insulation for a trip to Senegal and how temperature impacts melting.
Heating Things Up
This document provides instructions for an experiment to test the hypothesis that different colored objects will heat up at different rates when exposed to sunlight. Students will fill three identical cans - one painted white, one black, and one unpainted - with the same amount of water and use a lamp to heat them for 20 minutes, measuring the temperature change in each. They will record their observations and conclusions, and consider ways to improve or expand on the experiment.
Will the tissue get wet? Mini-science experiment
The document describes an experiment that was conducted to demonstrate that air takes up space. The experiment involved placing pieces of tissue paper and socks inside three glasses - one with no holes, one with a small hole, and one with many holes - and then inverting the glasses in a bowl of water. It was observed that the materials inside the glass with no holes remained dry, while the materials in the other glasses got wet, with the glass with many holes causing wetness the fastest. This supported the conclusion that air takes up space, since the holes allowed air to escape and be replaced with water.

This document outlines an agenda for a lesson on phase transitions that includes:
- A warm-up activity about water condensation
- A dry ice demonstration and questions
- Notes on the six phase transitions (freezing/melting, evaporation/condensation, sublimation/deposition)
- An experiment showing condensation forming on a cup and a student designed experiment to test the hypothesis that decreasing air temperature increases condensation
ECGS Module 3A
This document provides an overview of the scientific method and examples of its application. It begins with a review quiz testing knowledge of science concepts. It then outlines the basic steps of the scientific method - observation, research, hypothesis, experimentation, analysis, and conclusion. Examples are given of applying these steps to troubleshoot a power outage at home and to test if eggs can float with added saltwater. The document emphasizes organizing data in tables and drawing conclusions based on whether results support the original hypothesis.
Air experiments navàs catalonia
This document presents summaries of 3 experiments on the properties of air conducted by students at Sant Josep school in Barcelona, Spain. The first experiment shows that hot air expands and cold air contracts by placing a balloon-topped bottle in hot and cold water. The second experiment demonstrates that air takes up space by trying to submerge a ping pong ball in a jar with and without tissues. The third experiment illustrates that air pressure can crush an empty soda can by boiling water inside the sealed can and then quickly submerging it in cold water.
Diffusion lesson
This document discusses diffusion in particles including solids, liquids, and gases. It provides examples of gas and liquid diffusion, describes the processes of diffusion, and explains how diffusion differs between gases and liquids. Gas particles move freely and quickly without bonds, allowing gas diffusion to occur rapidly, while liquid particles still move freely but more slowly with bonds between them, resulting in slower liquid diffusion.
Air experiments
The document summarizes some key features of air through descriptions and experiments. It notes that air is colorless, odorless, and tasteless, yet has weight and fills all space. Experiments are described to show that air prevents water from passing through an upside down cup until it is tilted, and that air pressure keeps a card from sinking when placed on water in a beaker. Further experiments demonstrate air's ability to dry a coin submerged in water and how heated air in a glass lifts water. The document concludes by describing a homemade greenhouse and how it works to trap heat from the sun using aluminum foil and black cardboard around jars.
Experimentamos
The document describes 5 science experiments that students can conduct to learn about various scientific concepts:
1. The first experiment uses vinegar and eggs to demonstrate how the calcium carbonate in eggshells reacts with acetic acid in vinegar.
2. The second experiment involves creating a color spinning top to show how primary colors mix together and appear white when spun rapidly.
3. The third experiment uses magnets and toy cars to show the attraction and repulsion of opposite and similar magnetic poles.
4. The fourth experiment tests the conduction of heat through different materials like wood, plastic and metal spoons.
5. The fifth experiment transfers oil between cups using a playing card to demonstrate differences in density

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
