and ecology – pollution, conservation, ecosystems, nitrogen cycle, history
of life on earth, population growth.
(Spotlight Lessons): Ecology
Estimating Population Size – simulate mark and recapture by using small objects to trap and tag. A simple formula will tell you what the overall population size is which can be verified by counting the objects in the bag.
Owl Pellet Dissection – owl pellets are undigested bits of fur and bones that owls regurgitate. Students can examine the contents, reconstruct the skeleton of the prey and make inferences about the owl’s diet.
Interpreting Ecological Data – examine charts, data tables and graphs to answer questions about population size, growth, and carrying capacity.
Biome Project – as a group, investigate a biome and present to the class the main features, animal and plant species present and general climate.
Isopod Behavior Lab – collect isopods (pillbugs) and design a chamber to test their response to different environments, such as temperature, moisture, and substrate.
Compared to our unmonitored and frenetic movements of mind throughout the day, listening to music is a much more smooth and tranquil movement of the mind. Therefore, especially for beginners, music can be a helpful aid to meditation.
However, it is also a temporary aid. While listening to music is a tranquil movement of mind relative to our daily life, it is still a movement of the mind. Therefore, a point will come in which the music will be a distraction from the stillness of meditation. That is the time to abandon music for silence.
In that sense, music is like training wheels. It helps to get you going but it is eventually discarded as a restriction. It aids in the introversion of attention inward and once that is achieved its utility diminishes.
Personally I’ve never used music to meditate but whatever works, use it!
A landscape version of my previous vertical attempt. This was the last composition I took from the vantage point overlooking the epic Nant Gwynant valley. This shot looks down and across the valley, rising up towards the perfect peak of Snowdon/Yr Wyddfa, Crib Goch on its right, as the storm blew away the clouds.
Nant Gwynant, Snowdonia, Wales.
ISO100, f/16, ⅓sec at 16mm (24mm full-frame equiv.) using a 3-stop soft ND Grad filter to balance the bright sky. Tokina 11-16mm f/2.8 ultra-wide angle lens. Nikon D7000. This is a single exposure processed exclusively in Darktable with a lighter more painterly feel.
If you like the way my photos look, I have a free HDR photography tutorial using free and open-source software, so it costs you nothing!
Full-res versions of the photo for personal PC/mobile wallpaper use, as well as enquiries for prints, are available by request, just ask me.
Schizophrenia: patients usually have less brain tissue
Major Depression: scans show less brain activity in depressed brain
Alzheimer’s: brain tissue significantly shrinks, hippocampus is usually the first region to go
ADHD: less brain activity in the frontal cortex (area associated with decision making)
OCD: high brain activity
Post Traumatic Stress Disorder (PTSD): hippocampal volume reduction (area involved in memory) and increased activation of the amygdala (area involved in emotional responses)
This is so important! I usually don’t reblog posts but people need to understand that mental illnesses are NO CHOICE! You cannot get over it, or snap with your fingers and just be okay again. It takes constant fixing and a lot of strength to get out of this. So to everyone who judges people with mental disorders: people don’t get a choice to develop a disorder or not, but being stupid and telling them to get over it is a choice. PLEASE DONT JUDGE THINGS UNLESS YOU UNDERSTAND!
i wanna shove these in my mom’s face every time she says “just push through it”

"You are the body. Of course you are more than the body, but that ‘more’ will follow later on. First, you are the body. The body is your basic truth, so never be against the body. Whenever you are against the body, you are going against God. Whenever you are disrespectful to your body you are losing contact with reality, because your body is your contact, your body is your bridge. Your body is your temple."
