A web page and interactive applet illustrating the properties of a heptagon (7 sided polygon). The applet shows a heptagon where the user can drag any vertex to reshape it. User can see that the interior and exterior angles are constant in a regular heptagon, but vary in an irregular version. Controls allow the display or hiding of the diagonals, and triangles within the heptagon. The web page lists the properties of a heptagon including interior angles, exterior angles, sum of exterior angles, area, number of diagonals and number of internal triangles. Links to pages with generalized properties of all polygons. Applet can be enlarged to full screen size for use with a classroom projector.

In this interactive, learners develop the skills to handle a horse safely before entering the corral for the first time. The interactive consists of three stages, each explaining an aspect of the safety procedures necessary for leading a horse.

This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required include two aquariums, plastic wrap, 2 clamp lamps with 60 watt light bulbs, pebbles and rocks, modeling clay, blue food coloring, and water. Student worksheets, background information for teachers, and a scoring rubric are included. This is Activity 2 in Too Many Blankets, a module in the lesson series, Potential Consequences of Climate Variability and Change.

Use the sliders in the Rose-Colored Glasses SIM to play around with different colors for the light source, the car, and the glasses to answer these questions and learn more about the concept of light and color!

We have also created a short (2:44 min) tutorial video that goes into more detail on how to use this SIM for both you and your students.

In this demonstration, students explore the concept of greenhouse warming. They determine whether an increase in the amount of heat-trappping gases in the atmosphere can cause the temperature on Earth to rise. Students compare the relative heat retention in two experimental systems that are identical except for one being covered with plastic wrap. Materials required include two small aquarium tanks, plastic wrap, two clamp lamps with 60 watt bulbs, modeling clay, rocks and pebbles, and two thermometers. Teacher background information, student worksheets and a scoring rubric are included. This is Activity 1 of the module Too Many Blankets, part of the lesson series, The Potential Consequences of Climate Variability and Change.

In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that emits energetic helium nuclei (alpha particles), e.g., the mineral the mineral autunite, which contains uranium. This is activity two of four from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER).

An interactive applet and associated web page that provide step-by-step animated instructions on how to measure angles using a protractor. Specifically, it uses a protractor to measure two angles that form a vertical pair, verifying they have the same measure. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the incircle of a polygon - The largest circle the will fit inside a polygon that touches every side. The applet shows a polygon where the user can drag any vertex and change the number of sides. As they do so, the incircle is drawn for that polygon and the radius calculation is updated. Calculation can be turned off for class discussions. The text on the web page gives two formulae for calculating the inradius, depending on the initial givens.

This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can floats on water in a tray, such as a Petri dish. Students spin a magnet just inside the can without touching the can. The can begins to spin. Understanding what happens can be explained in steps: first, the twirling magnet creates an alternating magnetic field. Students can use a nearby compass to observe that the magnetic field is really changing. Second, the changing magnetic field permeates most things around it, including the aluminum can itself. A changing magnetic field will cause an electric current to flow when there is a closed loop of an electrically conducting material. Even though the aluminum can is not magnetic, it is metal and will conduct electricity. So the twirling magnet causes an electrical current to flow in the aluminum can. This is called an "induced current." Third, all electric currents create magnetic fields. So, in essence, the induced electrical current running through the can creates its very own magnetic field, making the aluminum can magnetic. This is activity four of "Exploring Magnetism." The guide includes science background information, student worksheets, glossary and related resources.

What Is It?

INNER EXPLORER PRESENTS A MINDFULNESS APP FOR FAMILIES - Helping Parents Raise Mindful kids.

Inner Explorer is a free mindfulness app (for Apple and Android) from Inner Explorer. Hundreds of school districts use Inner Explorer's mindfulness program to help educators and students become socially-emotionally present and handle situations with calmness and resilience.

Inner Explorer @ Home is specifically designed for parents and caregivers to use with their children and features daily guided mindfulness practices for all age-groups.

THE BENEFITS AND 5 W's OF MINDFULNESS
1. What is Mindfulness?
Mindfulness means paying attention to what’s happening right now with curiosity and kindness and without judgment.
2. Why Mindfulness?
Mindfulness is popular because it is very effective for reducing stress and for improving focus which helps learning.
3. When?
One can practice mindfulness any time. However, practicing mindfulness in the morning often sets the tone for a calm and lovely day.
4. Who?
Inner Explorer was designed for Pre K – 12th grade students. However, many adults utilize the program on a daily basis. Practicing as a family magnifies the benefits and creates calm and connection.
5. Where?
Practicing in as quiet a place as possible is always a good idea to minimize distractions.
