In this math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

In this activity (page 2 of PDF under GPS: Kinetic Sculpture Challenge Activity), learners will predict which objects have to overcome the most static friction to slide down a ramp.

In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.

In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this math lesson, learners apply the concepts of ratios and percentages to the distribution of letters contained in a box of Alphabits® cereal.
