This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More)

Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out. Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with... (View More)

This is a lesson about society and space exploration. Learners will survey the public about their different opinions about space exploration and the use of robotics in space exploration. Then they will represent and analyze the results. This is... (View More)

Learners will demonstrate the size (volume) differences between Earth, Earth’s Moon, and Mars. An extension is provided to estimate the distance between the Earth and the Moon, and the Earth and Mars, using the scale of the play dough planets'... (View More)

In this activity, students engage in an ongoing investigation to find patterns of sunlight and shadow in a classroom (or any room that gets sunlight) at different times of the day and different times of the year. Students look for repeating... (View More)

This activity enables students to better understand the motion of the Sun and how we use it to measure time. Students create a "horizon calendar" at their school by carefully observing and recording the horizon and the Sun at sunset (or sunrise, for... (View More)

In this activity, students engage in long-term systematic observation to learn about the apparent annual motion of the Sun caused by the Earth’s orbit around the Sun. Students put a dot on a window where sunlight enters the classroom (or any room... (View More)

In this activity, students learn about the motion of the Sun in relation to the Earth, and how geographic directions are defined. Students use a tetherball pole (or an alternative) as a gnomon and the shadow the Sun casts to determine the exact... (View More)

In this activity, students work in teams to calculate relative air mass and demonstrate how solar elevation angle affects the intensity of light that reaches an observer on the ground. The resource includes a student data sheet. This learning... (View More)
