Curated OER
Activity Two Teacher Page: Explosions
Students identify variables that affect the system, and specify which variables are independent and which are dependent.
Curated OER
Impulse/Momentum Lab
Students investigate the relationship between force and momentum using motion detectors and sensors. In this physics lesson plan, students graph experimental results. They calculate impulse using the area under the graph.

Balancing Bottles
Learners explore the Law of Conservation of Matter using effervescent tablets. In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and journal...
Curated OER
GUM: More, Less, or the Same?
Students confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.
Curated OER
Physical and Chemical Changes
Students examine the different changes in matter. In this chemical change instructional activity students determine the amount of reactant made in a reaction using the law of conservation.
Curated OER
Investigation of Hooke's Law Lab
Students determine the spring constant by conducting an investigation. In this physics instructional activity, students collect data and create a graph of force vs. displacement. They compare the results of two different methods to find...
Curated OER
Work and Energy
Students show that energy is conserved in the laboratory. They calculate the work done by a force on an object as the product of the force and a displacement of the object from a reference point.
Curated OER
Model Mania
Eighth graders study the conservation of matter. In this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity.
