In this activity, students observe fluid motion and the formation of convection cells as a solution of soap and water is heated. This procedure can be performed as a demonstration by the teacher, or older students can conduct the experiment themselves. A list of materials, instructions, and a description of the convective process are included.

Students learn the cause of the seasons on Earth and how this affects temperatures on Earth. Students learn that seasons are the four distinct times of the year when there is a change in temperature on Earth.

The students will paint and arrange spheres to form a model of the solar system. They will first make models using the plastic spheres of different sizes. Then they will make similar models using clay, cotton, etc., and organize them in the right order from the Sun.
This activity is based on a reduced-scale model of the Solar System …
This activity is based on a reduced-scale model of the Solar System built on a map of a city students are familiar with. This provides them with an understanding of the great distances between the different bodies of the Solar System and their relative size. Students will investigate the characteristics that are required from these bodies to build a scale model using common objects.

What is a star and what shape is it? Students explore both artistic and scientific representations of stars, learn that stars are like the sun but much further away and make their own star hat.

Have you ever wondered what happens to the different stars in the night sky as they get older? The Star in a Box application lets you explore the life cycle of stars. It animates stars with different starting masses as they change during their lives. Some stars live fast-paced, dramatic lives; others change very little for billions of years. The app visualises the changes in mass, size, brightness and temperature for all these different stages.

Street lights of the same type will look brighter when they are …
Street lights of the same type will look brighter when they are close to you, and less bright when they are farther away. The same applies to astronomical objects: a given star will look brighter to a nearby observer than to an observer far away. In both cases, the difference in brightness can be used to deduce the relative distances of suitable objects. Standard candles, objects of constant intrinsic brightness or whose intrinsic brightness can be determined by careful measurements, are a key tool for astronomical distance determination. In this exploration, you will explore standard candles (and also effects that complicate distance measurements) in a simple everyday setting, namely that of street lights, using a digital camera and freely available software.

Watch shadows during the course of the day to explore the influence of the Sun’s position in the sky on them, as well as how they change over the seasons. During the next season, repeat the experiment and note the changes from the previous season. Repeat over a period of one year for each season.

This activity teaches students on how the day and night occurs. It also teaches the student about the rotation of the Earth and what two people from opposite sides of the world experience at the same time.
