Your Weight on Other Planets
Students explore their weight on other planets. In this science activity, students view a presentation about the other planets and complete a worksheet in which they make predictions about their weight on the moon and other planets.
Curated OER
Hooke's Law
Students explore the relationship between the force applied to a spring and its stretch. They design and conduct an experiment to determine the stretch of spring with 15N of force without having an actual 15N mass.
Curated OER
Aerodynamics
Pupils discover the basic principles of aerodynamics, including the roles and identity of natural forces involved. They examine how the force of gravity is overcome by the curved shape of an airplane wing and air pressure.
Curated OER
Bird Populations
Students gather data about bird populations. They study bird migratory patterns using the methods that researchers use. They write an essay explaining the differences between the four types of population movements.
Curated OER
Keep the Environment Clean
Students discuss ways our environment becomes polluted. They make a list of ways to keep it clean.
Curated OER
Meteorology (Condensation)
Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the lesson.

Predicting: Making a Hypothesis
Students analyze information from various sources to create a hypothesis about the origin of a family artifact. Students create a hypothesis about the origin of the item and write a paragraph explaining why they believe the hypothesis is...
Curated OER
Plants
Students illustrate the major parts of a plant, classify some plant foods we eat as roots, stems, leaves, flowers, fruits and seeds. They also name some animals that use seeds, leaves, and fruit for food.

Students determine the power dissipated in the combination of two resistors connected in series to a 6 volt battery. This task assesses students' abilities to develop procedures for an investigation, develop a plan for recording and...
Curated OER
Coffee Cooling
Students explore the factors that affect how long coffee stays hot. They develop a question and a testable hypothesis for one factor such as initial temperature or size of opening of the container. Then they design and conduct an...
Curated OER
Friction Force
Students investigate friction force on a variety of objects such as bricks and cardboard boxes. They use a force probe to collect data on the changes in force required to drag the objects across a variety of surface types.
Curated OER
Ice Cold
Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER

The effectiveness of Antacids
High schoolers design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they...
Curated OER
Hydrated Salt
Students plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.
Curated OER
Catalase Enzyme
Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...
Curated OER
Car Wash
Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...
Curated OER
That's the Way the Ball Bounces
Students investigate and compare the bouncing ability of the materials from which four different balls are made. They determine which material performs the best for use as a basketball. After collecting data in a small group they...
Curated OER
Coat Caper
Students examine pollen and fibers taken from a garment. They analyze pollen from new hybrids and compare it to the samples from the garment then make individual conclusions concerning the specific historical authenticity of the garment.

Great Gravity, Batman!
Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...
Curated OER
Mixtures
Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.
