Tools and Equipment (Part 1)
Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...

Where Does a Plant's Mass Come From?
Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Similar Triangles
Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.

Consecutive Sums
Evaluate patterns of numbers through an engaging task. Scholars work collaboratively to determine a general rule reflecting the sum of consecutive positive integers. Multiple patterns emerge as learners explore different arrangements.

Proof with Parallelogram Vertices
Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional students to frame their responses.

Animals of the Fire Ice
When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

U Boat Hunt
Learners recognize patterns and sequences in numbers. In this geometry lesson, students create rules to define the sequences and patterns they obsere. They translate coded messages as they dicuss navigational terms.
Curated OER
Thoughts to Page: Explorations and Expressions
Learners are introduced to the correct techniques to use for proper writing. In groups, they practice the use of clustering to help them organize their thoughts and identify the main idea of their paper. To end the lesson, they write...
Curated OER
Sketch Up
Learners estimate and measure exact. In this geometry lesson, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.
Curated OER
Exponents
Sixth graders explore mathematics by participating in a SMART Board activity. In this exponents lesson, 6th graders identify the different exponential powers of a number and discuss how the power of the number accumulates. Students...
