Students examine electricity, what its uses are and how it works.  In this exploring electricity lesson students study voltage, resistance, current and OHM's law. 

Pupils make a plaster cast of tree bark. They use plaster casts of tree bark to make a simple classification system. Also, they use plaster casts of tree bark to identify individual trees.

Young scholars explore the concept of action potential and its effects on voltage-gated channels. Students compare and contrast a flushing toilet to an action. They examine its effects on the population of voltage-gated channels.

Students discover how inclined planes make work easier as they make mathematical predictions and prove their predictions through experiments.

Students explore how friction change motion and why friction is important. Students set up an incline plane. They slide wooden blocks down the incline plane and measure the distance from the end of the track that the block moved....

Students study the properties of fluids under different circumstances.  In this pressure fluids lesson students view a demonstration, complete an activity and describe what they learned. 

Students understand that an aquifer can become a non-renewable resource if it is not used wisely. Students do an experiment that recreates an aquifer in the classroom.

Young scholars explore simple machines and demonstrate thier acquired understanding by building a simple machine.

Students describe the size, shape and feel of a food hidden in a "feely bag" and then select the Food Model from a group that corresponds to the food. In a tasting party afterwards, they sample the food and describe the color, taste and...

Students decide on an activity like running, swimming or skating for a performance analysis. They have friends or family members videotape them as they exercise, then review the video to see how they can improve their performance.

Students learn how to use maps, compute mileage, and be physically active while exploring America's national parks, historical heritage, and nutritional information via key agricultural sites.

Students view a survey that looked at family life, education and healthy and safety and found life wasn't as good as it could be for lots of kids in the UK. All the viewpoints of the students is analyzed and discussed in depth within...

students will learn to respect the nature around them. This respect is vital because ignorance of surrounding nature can lead to carelessness when curiosity goes awry. A perfect example of this wayward curiosity took place at our school...

Fourth graders discover earth's air pressure through observation of several experiments. In the "Experiment of the Leaky Bottle," they observe how air pressure forces water out of the lowest hole farther than the holes above it. In...

Students recognize and observe weather phenomena. In this four part weather lesson, students are introduced to weather symbols through a story, then use a thermometer to measure water temperature. Next, students observe the formation of...

In this vocabulary worksheet, students choose the correct word to fill in blanks in a set of 16 sentences; link is present for answers.

Learners explain the processes involved in the rock cycle. In this earth science lesson, students identify the different kinds of rocks. They complete a worksheet during the activity.

Students are asked to create a bungee jump that will protect a hard-boiled egg from breaking. A force sensor is needed to measure the push/pull forces on the egg. Data is inserted into force-time graphs. After completing three...

In this physics lab (best done outside), students will explore Newton's Third Law - 'For every action there is an equal and opposite reaction'. Students will fill empty 35-mm film canisters with water and part of an Alka-Seltzer tablet,...
