To develop their skill at drawing inferences from observations, sixth graders rotate through six stations, conduct a series of experiments, make observations, and draw inference from what they observe.

Wiggle your way through lab day! Young zoologists observe and infer the effects of different stimuli on earthworms during an engaging lab from the K20 series. Lab partners set up four different controlled environments, then record how...

Is this resource a great way for your class to observe bonding between oxygen and hydrogen? OH yeah! Scholars learn about the changes in kinetic and potential energy as molecules of oxygen and hydrogen interact. Kinetic, potential, and...

Ready to take your chemistry class on its first big lab adventure? Dive in to differentiation between chemical and physical changes with a thoughtfully designed set of experiments! Partners conduct a series of reactions, describe their...

Bored with frog and earthworm dissections? Had your fill of fetal pigs? Anatomy students will be intrigued by the sheep's brain, and you will be prepared with guiding questions, extension activities, and pictures as they dissect one —...

Can a coral cure cancer? Take seventh and eighth grade science sleuths to the underwater drugstore for an investigation into emerging pharmaceutical research. The fifth installment in a series of six has classmates research the wealth of...

How do you teach kids to "science" effectively? Inquiry cubes are a "sort of" puzzle with no answer—promoting even more questions! Group members work together to use the evidence on the visible sides of each cube to infer what lies on...

Take your class inside a beaker for an up-close view of a chemical reaction! Junior chemists examine how chemical reactions occur using an interactive resource. The activity allows users to change the temperature and observe how it...

Need a bright idea for an engaging lab? Watch your class light up as they explore the difference in efficiency between incandescent and LED bulbs! The resource makes use of simple materials and encourages learners to infer what's...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Which intermolecular force is the strongest? Scholars test the relative strength of London dispersion forces, dipole-dipole interactions, and induced dipoles using a simulator. The interactive allows learners to pull on paired molecules...

How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Investigate the growth and development of New York City with the final lesson in this four-part series on skyscrapers. Learners first explore the concept of urban growth by looking closely at a series of three paintings made of Wall...

Can a sponge cure cancer? Life science pupils visit the drugstore under the sea in the fifth instructional activity of six. Working groups research the topic then get hands-on experience by testing the inhibiting effects of several...

Explore the circulatory system with a cardiovascular pump activity that promotes discovery and discussion as class members create a functioning model of the heart. Continue the learning process through a web quest showcasing the...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Create a neuron frenzy as your pupils play the part of the neurons. An engaging lesson plan creates a human chain of neurons that pass cotton balls posing as neurotransmitters. Scholars learn about pre- and post-synapses as they...
