In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

En esta actividad, los aprendices leen sobre como Mateo y Cientina conducen una investigación forense para descubrir quien llevó unos dulces.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

In this environmental health activity, learners investigate their own vital lung capacities.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity (on pages 16-21), learners get a sense of geological time by understanding how big a million is.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of
