MOUNTAIN RANGES & CONTINENTAL DRIFT

How plate tectonics shapes our planet

Mr. Andersen describes how plate tectonics shapes our planet. Continental and oceanic platers are contrasted and major plate boundaries are discussed.

Continental Drift

A brief overview of the theory of continental drift and the evidence supporting it. This video explores how the apparent fit of the continents, fossil and rock correlation, and paleoclimate data support Alfred Wegener's ground-breaking theory.

This animation shows the plate tectonic evolution of the Earth from the time of Pangea, 240 million years ago, to the formation of Pangea Proxima, 250 million years in the future.

Interactions between species

Interspecific and intraspecific relationships

From this video you should know the difference between interspecific and intraspecific, and that interactions can be positive, negative or neutral.

Community Ecology

Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along

HABITAT & NICHE

Difference between habitat and niche - ecology

Learn how the habitat and niche are different but also very important for a healthy environment.

A habitat is an ecological area where a plant or animal lives. It may be an island, a tree, or maybe under a rock. The habitat is where an individual can find food, shelter, protection and mates.

A niche is a role or position that an individual has in its environment. A niche may also involve what the individual eats, how it interacts with other living things, and also how it interacts with the nonliving factors. Without ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

INVASIVE SPECIES

The basics
What are Invasive Species? An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan's economy, environment, or human health.

The threat of invasive species.
An invasive species can be anything from plant, animal or fungus that is introduced to a non-native habitat and has a tendency to spread to a degree that causes damage throughout the environment, human health or economy.

What is an ecosytem?

In this video you'll learn all about ecosystems and how energy is transferred between organisms living together it the same environment.

Adaptations to the enviroment

What Is Adaptation? 

Learn about how organisms adapt to their habitats. "Adapting and Living Together" within the Ecology and Environment topic for school level biology.

More explanations and examples of different types of organism adaptations, including: structural/physical adaptations, behavioural adaptations and physiological adaptations

Producing thousands of copies of a gen:PCR

PCR & CRISPR

• PCR

Polymerase chain reaction (PCR) is a method widely used in molecular biology to make many copies of a specific DNA segment.

This is a very basic video about PCR

Answer the following questions:

a) How can humans manipulate the DNA for our own benefit?

b) How can many copies of a gene be made for analysis?

c)  How can this used to detect the COVID-19?

• CRISPR

In this video Paull Andersen tells how the inmune system CRISPR/CAS 9 was identified in bacteria and how this system was used to edit genomes.

Introduction

This blog is created as a class blog to help the BC Project students with the learning of Natural Science concepts and with the ability to reason critically and solve problems.

The topics will include Astronomy and Space, Geology, Biology, Physics and Chemistry.

I expect and hope that it is useful. Enjoy it!
