Writing a number is all in the notation. The resource introduces the class to scientific notation. Pupils learn the process of taking a very large or small number in standard form and write it in scientific notation. To practice,...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Model how the sun's energy strikes the planet and help your class relate it to a climate map. Assign small groups an individual climate zone to discuss. They reflect on and research how humans survive in the assigned climate and write a...

It is just magnetic. This resource presents the concept of Earth's and another planet's magnetic field and how spacecrafts detect them. Learners study a problem using magnetometers and participate in three experiments to come up with a...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.
