Cleaning Water: A 5th Grade Standards-Based Science Unit

Many children around the world die due to drinking contaminated water.  This engaging science lesson will allow students learn how to build and use a simple homemade filter system to clean contaminated water. This 5th grade, standards-based lesson is great for California Science Content Standards Earth Sciences.  Students make observations, collect data and form hypothesis.  The end result is a gratifying surprise that they will enjoy while learning basic investigation and experimentation concepts.

Energy Conversion in Electricity – Resistors and Circuits (lesson three of eight)

Author(s): Ben Engel, Arthur Millius, Lisa Monti and Helen Wong-Lew

Energy Conversion in Electricity – Resistors and Circuits (lesson three of eight)

Students are introduced to the concept of a resistor and reminded about electrical energy from the previous lesson. They are then challenged to build a GIANT circuit to determine whether the size of a circuit affects whether it lights a bulb. They build as a class a giant series and giant parallel circuit. Then, in pairs, they build their own circuits with different resistors.

Making a battery

This is an inquiry-based activity in which students are given materials to make a battery. Students work in pairs and results are shared with the class. Content is discussed after the hands-on session.

Alternative Energy Part II (lesson eight of eight)

Author(s): Ben Engel, Arthur Millius, Lisa Monti and Helen Wong-Lew

Alternative Energy Part II (lesson eight of eight)

Student take their cars outside to a "time track" and a "distance track". They measure how fast their car goes 10 feet on the "time track" and how far their car goes in 30 seconds on the "distance track". They perform multiple trials, interpret their data, and predict which region in the world the car would be most suitable for.

Alternative Energy Part I (lesson seven of eight)

Author(s): Ben Engel, Arthur Millius, Lisa Monti, Helen Wong-Lew

Alternative Energy Part I (lesson seven of eight)

Students design a car that could be powered without gasoline. A class discussion ensues on different energies you could use to power a car. The students receive a model car kit with alternative modes of propulsion and get to design a car based on a form of energy they choose.
