Blue Coral Guide to the Solar System is fully responsive in the web browser for large and small devices in both horizontal and vertical orientations.

Brain development can be damaged by environmental chemicals.
Philippe Grandjean, University of Southern Denmark and Harvard School of Public Health, explains the erroneous assumptions made over time about this. Studies from Faroe Islands, where people have been exposed to toxic agents, shows how this affects brains of children and their IQ levels.

A presentation with Professor Philippe Grandjean about the dangers of chemical interference with the developing brain. This presentation, “Children’s health - Risks to brain development from exposure to environmental chemicals”, presented on 6th November, 2019, meeting of the French High Council for Public Health (Haut Conseil de la Santé Publique, HCSP), at the Ministry for Solidarity and Health in Paris.

This is an on-board guidance computer used in the Gemini program. In contrast to Mercury capsules, which had no on-board computing capability, Gemini spacecraft required an on-board computer to assist in rendezvous operations and in maneuvers to change its orbit. Both were necessary steps to lunar expeditions undertaken with Project Apollo.

Geologist Peter Appel and miner Leoncio Onay tells about an alternative to mercury use in small and artisanal gold mining giving a higher yield with gold and avoiding pollution and poisonings with mercury.

Students are introduced to concepts of hypothesis testing using elementary hypothesis tests, t-tests, and p-values as they compare a given fish population for methylmercury levels (using real and hypothetical data) against real-world mercury standards.

Students are introduced to concepts of sampling distributions and hypothesis testing using a simulation applet, elementary hypothesis tests, t-tests, and p-values as they compare a given fish population for methylmercury levels (using real and hypothetical data) against real-world mercury standards.

When astronaut John Glenn made history as the first American in orbit, his custom spacesuit helped him make the journey.

This illustration was prepared using whimsical app and it describes the cause, effects and control measures of Minamata disease.

Mercury is the closest planet to the sun. It has no atmosphere and is, as such, covered in craters. It's also incredibly hot but, surprisingly, has water ice hiding beneath its surface.

Mercury's Orbit
Mercury's Rotation - Orbit Ratio
A Weird Day on Mercury
Mercury's Craters
Mercury's Internal Structure
Deep Crater Water Ice on Mercury
Review

Students explore Mercury and Venus, the first and second planets nearest the Sun. They learn about the planets' characteristics, including their differences from Earth. Students also learn how engineers are involved in the study of planets by designing equipment and spacecraft to go where it is too dangerous for humans.

Geologist Peter Appel and a miner Leoncio Onay tells about mercury free gold mining by the ‘gravity-borax method’.

Methylmercury contamination within fish populations is an important toxin that affect human, animal, and environmental health, serving as a carcinogen (cancer-causing agent) and endocrine-disruptor (compounds that in some way alter the signaling of the hormone system. The impacts of exceeding safe dietary methylmercury levels were tragically made clear in Ontario, Canada, where a First Nations community in Grassy Narrows are living with the consequences of methylmercury poisoning in the fish supply. The fish were contaminated due to the dumping of mercury in the traditional waterways of the First Nation community. In 2016, there were highly publicized protests in Muskrat Falls, Labrador, Canada, where the Inuit people raised direct concerns about the potential for a proposed Nalcor Energy hydroelectric dam, to increase mercury levels in fish in those waters, which are an integral part of their traditional diet. Despite significant protests, the project was completed in 2019 and 41 km were flooded. This module uses these real-world examples as a jumping-off point for exercises that will guide case-study driven discussion on mathematical, biological and ethical concerns.

Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they explore the "mind-boggling mysteries" of our solar system. The article opens with a quick review of what we know about our solar system and how we've gathered that information. Students then "explore the mystery" of each planet within our solar system, which is presented though fun facts, evidence, theories, and NASA missions. The article ends with a nine-question quiz that gives students a fun way to test what they've learned.

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine disruptors - and ultimately, humans are responsible for it all.

Chapters:

a) Carbon
b) Nitrogen and Phosphorous :2
c) Cyanide
d) Mercury
e) Sulfur & Nitrogen Dioxide

This OLogy activity gives kids a grounded way to understand the scale of the planets in our solar system. The activity begins with a brief overview that tell them why all planets are round and introduces them to the concept that the planets vary widely in size. Kids are then asked to create a model of the solar system using found objects that match the provided scale in inches for the planets. The activity ends with a series of challenges, which include arranging the planets according to size and distance from Earth.

To understand the challenges of satellite construction, student teams design and create model spacecraft to protect vital components from the harsh conditions found on Mercury and Venus. They use slices of butter in plastic eggs to represent the internal data collection components of the spacecraft. To discover the strengths and weaknesses of their designs, they test their unique thermal protection systems in a planet simulation test box that provides higher temperature and pressure conditions.

Students are introduced to concepts of sampling distributions, p-values, and hypothesis testing. Using both simulated and real data for methylmercury level in fish populations, students will determine whether observations fall within government safety guidelines for safe consumption.
