Indirect Teacher Resources

For this math worksheet, students will work in small groups to measure the height of objects, such as trees, using their shadows. Students will be able to determine heights of objects that cannot be directly measured.

Students measure using tools they have made. In this algebra lesson plan, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.

Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Studying what you can't see can be challenging. Discover how scientists use indirect measurements to prove the existence of planets and estimate their sizes. The introduction explains the symbiotic movement of planets and stars during an...

A celestial body's distance from Earth makes studying its characteristics much more difficult. Learn how scientists use indirect measures to determine the size of stars. The interactive activity has individuals adjust the size of binary...

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

Flat, positively curved, or negatively curved ... what is the true shape of the universe? Scientists use many indirect measurements to base their theories on the shape of the universe. Using an installment from the SciShow Space series,...

Middle schoolers, by conducting simulations, explore the effects of direct and indirect sunlight on heating of the Earth.

Students explore the concept of equivalence as it relates to comparing concrete objects to determine greater or lesser attributes such as length and weight. In this pan balance-shapes instructional activity, students make estimations...

Explore the role of government in the economy market. Young scholars analyze the economic decision-making process and how it takes into consideration additional cost, benefits, and public awareness of what they are trying to accomplish....

Students explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

Similar figures have corresponding sides and corresponding angles. With this in mind, missing values can be found by using a scale factor. Not sure how to do that? Watch this video as the instructor illustrates how to set up the known...

Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

In this geometry worksheet students explore similar polygons and determine measure of missing sides and angles. Students use indirect measurement with similar triangles and determine the area and volume of similar figures. The seven page...

Sixth graders increase their estimation and measurement skills in regard to the metric system. After a lecture/demo, student groups weigh and measure a variety of objects using metric measurement.

Students practice measuring items with non standard units. In this units lesson plan, students measure shapes, lengths, and classroom objects.

Three angles of one triangle are equal to the corresponding angles in another triangle. Use a ratio of corresponding sides to find the scale factor. Actually, there are two scale factor values. The instructor will explain how to get both...

Painting an irregular figure can be tricky if we don't know the exact area. This interactive presentation reveals that irregular figures can be broken into smaller, simple figures that use the area formulas. Go through two examples,...

Pairs or small groups work together to determine the height of a tree using similar triangles. Learners make a judgement which direction to let a tree fall to avoid hitting any structures. They then write letters to the principal...

Eighth graders participate in an experiment that emulates a sonar signal bouncing off the ocean floor. They determine how the ocean floor is measured by the length of time it takes for the sonar signal to return. They work with a wooden...

In this experimental relationship worksheet, students read about direct and indirect relationships between variables in experiments. They answer three questions about relationships between variables.

In this similar figure worksheet, learners use similar figures and indirect measurement to determine distance.  They use proportions of similar figures to determine scale figures.  This two-page worksheet contains 8 problems.  Answers...

In order to learn about the Pythagorean Theorem, young mathematicians investigate relations and patterns between different sides of a right triangle to look for possible relations among the squared sides. Once they have established the...

There's nothing quite like a glass of ice-cold, freshly squeezed lemonade. Lesson seven of this series explains how the water humans need to survive can come in many forms. Teach your class about how much water humans require every day...
