Demonstrate the movement of lithospheric plates due to convection in Earth's mantle. Learners then model the movements that occur along plate boundaries using colored clay. 

In this science worksheet, learners learn about surface tension by performing an investigation with drops of clean and soapy water on a penny.

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Invite your class to dig in to an engaging journey into the world of mining! Here you'll find the tools to equip young miners with knowledge of soil, rocks, and minerals, as well as types of mining operations. To round things out, the...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Students complete a variety of lab and discussion activities as they are introduced to ethics and honest lab practices. They perform various biology, chemistry, or physics labs which test their ethical lab practices.

In this science worksheet, middle schoolers examine the topic in order to solidify knowledge covered in the curriculum using puzzles and creative games.

Students use the various steps of the scientific method to construct and carry out a detailed laboratory investigation (including a control). They demonstrate how various environmental factors may affect the process of seed germination...

Your class can investigate the weather through an experiment. In this chemistry instructional activity, learners collect data on air pressure and relate it to the weather. They collect data with the TI containing a barometer probe.

Young scholars use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...
