You definitely want to check out this mole! Chemistry scholars experiment to observe an unobservable quantity with an engaging lesson plan from K20. Partners collaborate to determine what's inside an opaque box, then complete a series of...

Learners of light will construct a contraption in which light is passed through a prism and shone into a box. The temperatures at different points along the path and outside of the path of light. The intent is to imitate William...

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

Don't cast a great hands-on resource aside! Scholars learn about the process of casting by actually trying out an example. Plaster of Paris and cookie cutter molds help them complete the activity.

Biodiversity is essential for every habitat, but many species are at risk due to pollution and other factors. Explore several different species native to Illinois in a gallery walk with posters that learners have created after research...

Ozalid acid paper is sensitive to the light. It reacts by getting darker, and it's the same paper photographers use when they print their pictures. Here, kids get to use photo-sensitive paper to create sun prints to find out...

Apply the principles of geology to a series of collaborative, hands-on class activities. Young earth scientists learn more about igneous, metamorphic, and sedentary rocks before classifying and weathering rocks that they find....

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

Communicating results is just as important as getting results! Learners create a poster to highlight their findings in the experiment conducted in the previous lesson in a 30-part series. The resource provides specific criteria and...
