In this lesson, students download cloud and surface data from the NASA CERES S-COOL website student observation database, then develop and compare graphs to explore the relationships between surface temperature, pressure, and humidity. Students then investigate possible patterns in cloud-types and the surface conditions for several locations on a particular date of their choice from the S-COOL data. ... Full description.

Ships travelling between Lake Ontario and Lake Erie use the Welland Canal. Beginning with a conversation between characters Mathise, Geo, and Trig, they explain how a lock in the canal operates by gravity alone, without pumps. The characters use mathematics to solve problems such as how long the locks take to fill and how to express the volume and flow of water in more common terms (bathtubs of water ... Full description.

In this activity students construct a sundial and use it to observe the movement of the sun through the sky over the course of a day by marking changes in the position of a shadow once each hour. Students determine the approximate time of solar noon at their school as indicated by the time of the shortest shadow. They revisit the site on a subsequent day to estimate the time of day using their sundial. ... Full description.

The purpose of this activity is to discover why an instrument shelter is built the way it is. Students construct shelters that have varying properties and place them in the same location or place similar shelters in different locations and compare temperature data taken in each shelter. Students should predict what will happen for each of the different shelter designs or placements and perform the ... Full description.

The purpose of this resource is to use a land cover type map to make environmentally sound decisions. Full description.

In this activity students will build a Lego vehicle that can traverse glacial ice. The vehicle should be capable of carrying a specific load and glide smoothly, creating as little effort as possible for the skier pulling it. This activity can be a two period exercise, as it is here, where students choose a sled design that weighs the least and creates the least amount of friction when crossing the ... Full description.

This lesson is intended to make students aware of the need to respect their environment and its natural resources. They will apply that knowledge in developing an "ecologically sound" city. Using an outline, they will design a city that has ecological laws, power source(s) for lights and heat, a river, two industries, and homes for its population. Full description.

This interactive feature provides younger students with basic information about Mars. Topics include the length of the Martian day, the size of the planet relative to Earth, and its gravity and atmosphere. There are also features on the search for life on Mars and what forms it might take, as well as a downloadable activity in which students conduct an 'interview' with the planet and provide the answers. ...

In this lesson, students will learn that there are limits to what the eye can see and that a magnifying glass can help extend those limits. Students may have been exposed to optical technology such as glasses, magnifying lenses, or even periscopes, microscopes, and telescopes. This lesson aims to channel the inventive energy of students to increase their awareness and purposeful use of tools. They ... Full description.
