Rocks and fossils can provide information about geological events and changing life forms in the past. The principles of original horizontality and superposition allow scientists to determine the relative order and age of rock layers, though not precise dates. Absolute dating methods like radiocarbon dating measure radioactive decay to determine the specific ages of rocks and fossils.

Describe how layers of rocks (stratified rocks) are formed,
Describe the different methods (relative and absolute dating) to determine the age of stratified rocks, and
Explain how relative and absolute dating were used to determine the subdivisions of geologic time.
The relative age of a rock is its age when compared with the ages of other rocks The absolute age of a rock is a calculation of the number of years that have passed since the rock formed.
Grade 8 Integrated Science Chapter 16 Lesson 3 on absolute age dating of fossils. This lesson follows the last lesson about relative age dating. This chapter describes radiometric age dating with explanations of radioactive decay and half-life. There is also a short explanation of igneous, metamorphic, and sedimentary age dating. The goal is that students understand radioactive decay, half-life, and how this can be used to determine the age of carbon fossils and different types of rocks.

1.1 IntroductIon
The average introductory geology student’s perception of geology normally in-
volves the memorization of rocks and discussions of natural disasters, but Geology
contains so much more. Geology is the study of our planet, which is vital to our ev-
eryday lives from the energy we use, to the growing of the food we eat, to the foun-
dations of the buildings we live in, to the materials that are used to make everyday
objects (metals and plastics). The ideal place to start this course is discussing the
methods that are used to better understand our planet, the processes that shape it,
and its history.
Science is not a set of facts to remember. Instead it is a method to discover
the world around us. You are likely already familiar with the Scientific Method,
but it is worthwhile to review the process. The first step of the scientific method
is making an observation or learning the background surrounding the question in
which you are interested. This can be done by taking classes on a subject matter
as you are doing presently in geology or by simply taking careful notes about your
surroundings. Based on your knowledge and observations, you can then make a
hypothesis, which is a testable prediction on how something works. A hypothesis
should be framed in a way that is easy to test and prove wrong. This might sound
odd, but science works to rigorously disprove a hypothesis and only those that
withstand the tests become accepted. The wonderful aspect of this definition of a
hypothesis is that the testing results in a brand new observation that can then be
used to formulate a new hypothesis. Therefore, whether the hypothesis is verified
or rejected it will lead to new information. The next step is communication to other
scientists. This allows other scientists to repeat the experiment as well as alter it in
new and unthought-of ways that can then expand on the original idea. These few
steps encompass the vast majority of the scientific method and the career of any
individual scientist. As hundreds of related observations and tested hypotheses
accumulate scientists can formulate a theory. The scientific meaning of a theory is
an explanation for a natural phenomenon that is supported by a wealth of scientific

data. A theory is not yet a law because there still may be some debate on the exact
workings of the theory or the reasons why a phenomenon occurs, but there is little
debate on the existence of what is being described.
This leads us back to Geology, the scientific study of the Earth. There are as-
pects in geology that are directly testable, but others are not and geologists must
become imaginative in discovering aspects about the earth and its history that we
will never be able to directly observe. In this laboratory manual we will discuss the
materials that make up the ear.

DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
