This report describes the findings of two scientists who studied the chemical makeup of crystals of zircon from rocks in Western Australia's Jack Hills. The zircon crystals are thought to be 4.5 billion years old, making them some of the oldest materials yet found on Earth. The ratios of oxygen isotopes found in the crystals suggest that conditions during the Hadean Eon, the first 500 million years of Earth's history when the crystals were formed, were cooler and wetter than previously thought. Links to a glossary are embedded in the text.

ANCIENT ECHOES INTERPRETIVE CENTRE is nestled at the junction of the Coalmine Ravine and the Eagle Creek and offers both indoor and outdoor tours of our Palaeontology sites (dinosaur and fossil displays and dig), Prairie Grasslands Ecology (virgin prairie medicine and food plants, animals in the wild and taxidermy displays), and First Nations History (petroglyphs, rock formations, effigies, archaeological dig, teepee rings, buffalo jump, food processing site, tool artifacts and pottery making displays). A permanent art exhibition by Metis artist, Jo Cooper, expresses a visual and oral story with “The Disappearance and Resurgence of the Buffalo”. Additionally, sculptures outside the centre stimulate the imagination as well as humour. Ancient Echoes is currently operating under their summer hours, which run from May 7th to August 31st. This means we are open Tuesdays-Sundays from 9:00 AM - 5:00 PM (closed Mondays). Bookings can be made by calling the Centre at 1-306-377-2045 or emailing anciente@sasktel.net. Our Valley View Tea Room is open every Friday from 2:30-4:30 PM in May-August.
Ancient Echoes is a popular site for School Tours throughout the year offering custom-designed programs for students of all ages in the areas of Aboriginal History, Paleontology, Ecology, and Archaeology.
Ancient Echoes also offers regular summer programs including traditional pottery making, drum making, ecology and palaeontology hikes, full moon walks, educational and craft days for children, as well as numerous other “ project” days. A video of the ravine walk is available indoors for “rainy days”, or for those who do not wish to hike.
Ancient Echoes has just recently added a beautiful art gallery space to their walls. Our new Prairie Echoes Gallery offers numerous exhibits throughout the year of new and established artists and photographers.

Students use the model of the infamous Bill and Ted from the feature film "Bill and Ted's Excellent Adventure" to "go back in time" to learn about deities in the ancient world. After researching, studying, and viewing reproductions of artworks that depict gods and goddesses, students transport their chosen deities to the modern world as characters they write about in a mock television talk-show script, which they enact for the class.

With wisdom and wit, Anupam Mishra talks about the amazing feats of engineering built centuries ago by the people of India's Golden Desert to harvest water. These structures are still used today -- and are often superior to modern water megaprojects. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 17-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

The history of medicine is about two of our big questions: one, what is life? What makes it so special, so fragile, so… goopy!? Two, how do we know what we know? Why should I take my doctor’s advice? Why are deep-fried Oreos bad for me? It may be tempting to look at medicine as a science that has simply progressed over time—that medicine used to be bad, and its history is a story of how it got better.

Students review the basic conventions for using quotations from literature or references from a research project, focusing on accurate punctuation and page layout, then apply the conventions to their texts.

Students will identify nouns, verbs, and adjectives visible in two paintings depicting a stormy and calm landscape, respectively. They will write a narrative inspired by the paintings, paying attention to transitional phrases and sensory details. Students will use color and line to create their own calm or stormy landscape.

Students prepare for the associated activity in which they investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Based on the experimental set-up for the activity, students form hypotheses about the acceleration of the device. Students will investigate how the force on the device changes according to Newton's Second Law. Different types of acceleration, including average, instantaneous and constant acceleration, are introduced. Acceleration and force is described mathematically and in terms of processes and applications.

In the first of two sequential lessons, students create mobile apps that collect data from an Android device's accelerometer and then store that data to a database. This lesson provides practice with MIT's App Inventor software and culminates with students writing their own apps for measuring acceleration. In the second lesson, students are given an app for an Android device, which measures acceleration. They investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Then they use the data to create velocity vs. time graphs and approximate the maximum velocity of the device.

Students develop an app for an Android device that utilizes its built-in internal sensors, specifically the accelerometer. The goal of this activity is to teach programming design and skills using MIT's App Inventor software (free to download from the Internet) as the vehicle for learning. The activity should be exciting for students who are interested in applying what they learn to writing other applications for Android devices. Students learn the steps of the engineering design process as they identify the problem, develop solutions, select and implement a possible solution, test the solution and redesign, as needed, to accomplish the design requirements.

Students investigate the motion of a simple pendulum through direct observation and data collection using Android® devices. First, student groups create pendulums that hang from the classroom ceiling, using Android smartphones or tablets as the bobs, taking advantage of their built-in accelerometers. With the Android devices loaded with the (provided) AccelDataCapture app, groups explore the periodic motion of the pendulums, changing variables (amplitude, mass, length) to see what happens, by visual observation and via the app-generated graphs. Then teams conduct formal experiments to alter one variable while keeping all other parameters constant, performing numerous trials, identifying independent/dependent variables, collecting data and using the simple pendulum equation. Through these experiments, students investigate how pendulums move and the changing forces they experience, better understanding the relationship between a pendulum's motion and its amplitude, length and mass. They analyze the data, either on paper or by importing into a spreadsheet application. As an extension, students may also develop their own algorithms in a provided App Inventor framework in order to automatically note the time of each period.
