This activity allows students to: 1. Identify the pairs of angles formed when a transversal intersects two lines.: 2. Measure angles Using Cabri Jr. 3. Identify relationships between pairs of angles when a transversal intersects parallel...

Each time students add ten marbles to a container filled with a small amount of water, they measure the height of the water. Students will examine their data and develop linear equations.

Different types of hot dogs will cool at different rates after they have been cooked. This activity takes the first steps in investigating this phenomenon by measuring the rate that a warmed hot dog cools. Students can compare the...

Students use the gas sensors to measure the amounts of oxygen and carbon dioxide consumed or produced by a plant during respiration and photosynthesis. They also determine the rate of respiration and photosynthesis in a plant.

In this activity, students will explore the concepts underlying the Triangle Inequality Theorem by comparing side lengths and angle measures of a triangle. They will use an interactive construction to see why this theorem is true.

This probeware version of the Skills Practice Lab Brightness of Light from the chapter Light and Reflection uses a light probe to measure the intensity of light at different distances from a light source.

In this activity, students can use a light probe to measure the light intensities of light bulbs with different wattage ratings.

Students use a pH sensor to measure the pH level of water in a stream or lake. They examine how air pollutants like sulphur dioxide, nitrogen oxides, and carbon dioxide cause acid rain, which affects the pH of water bodies and aquatic...

Use the Axes and Measure Angle tool to explore and calculate complementary angles.

JASON Aquatic Field Study: Explore how most aquatic animals and plants need clear water to survive by performing an experiment to measure the water clarity of a local aquatic site.
