Students study the development of batteries. In this electrochemistry lesson, students compare the different types of batteries. They explore its applications especially in the medical field.

Students explore diffusion or scattering of light. In this physics lesson, students explain why the sky is blue and sunsets/sunrises are red.

In this safety worksheet, students create a map of their science laboratory at school in order to know where the safety equipment is located in case of an emergency. They identify the given safety features on their map.

Young scholars identify the different sources of radiation around us. In this physics lesson, students calculate their estimated radiation exposure per year. They research a current issue about radiation.

Third graders experiment with magnetic force and magnetic fields. They examine how magnetic forces can act through a distance.

Students discuss the definitions of physical and chemical properties and changes. They vaporize a solution of salt and water, observing the sodium chloride that is left behind.

Fourth graders, in groups, determine whether bacteria arises from non-living things,

Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...

Students explain how water changes from vapor to liquid with a change in temperature by engaging in this experiment. They use a worksheet imbedded in this lesson to guide their inquiry.

Students identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.

Students explore the different types of pollution. they conduct experiments using dye mixed with tap water to measure the levels of dilution. They discuss at what point the dye (pollution) would be diluted enough to be safe to drink.

Students are introduced to the wave nature of light. In groups, they discuss Young's experiment and how diffraction and interference demonstrate the wave nature of light. Using examples, they show constructive and destructive...

Learners demonstrate that living organisms may possess incredible adaptations which enable them to survive. They observe bacteria that are able to orient themselves using the Earth's magnetic field and formulate a hypothesis as to how...

Students read a New York Times article as a class and discuss how groundwater near a nuclear test site may have been contaminated. They explore how groundwater contamination can spread through aquifers by participating in a simulation.

Young scholars explore DNA recombination. In this biology lesson, students observe the growth of microscopic species. They predict the phenotype of the transformed colonies.

Young scholars experiment with Thin Layer Chromatography to separate pigments found in flower petals.

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Students review experiments testing the photo degradability of the six-pack plastic ring and complete further experiments on the process.

Third graders, in groups, research animals, plants, and conditions found in ecosystems.

Students experience and practice compositing and recycling through hands-on-activities. They distinguish between which items from their trash can be recycled, composted and reused. The process for making recycled paper is also covered in...

In these word choice worksheets, students read the sentences and select the correct option to complete the sentence from the words whose or who's.

Learners measure water and make predictions about efficiency.

Students create a soil center on their school grounds. They begin to write in their science journals. They participate in an experiment that helps the community begin their own gardens.

Students perform an experiment to compare the sensitivity of the various developmental stages of Red Flour Beetles to ultraviolet radiation. Larvae, pupae and adult beetles are exposed to a source of UV-B radiation. In groups, they...
