Curated OER
Bioluminescence
Students differentiate chemiluminescence from bioluminescence. In this biology lesson, students explain how fireflies and other animals emit light. They discuss the applications of engineered bioluminescence.
Curated OER
Crystallization
Eighth graders analyze physical change in mass. In this chemistry activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with...
Curated OER
Plankton / Phytoplankton
Students discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.
Curated OER
Antacid Tablet Race
Students compare the reaction rates of effervescent antacid tablets under different conditions. They investigate methods of increasing the power of rocket fuels by manipulating surface area and temperature.
Curated OER
Analyzing Birds and Planes
Students find a variety of topics and subjects in this lesson. In the math section of this lesson, students graph linear equations and analyze their data. They solve one and two step equations to find the variable.
Curated OER
Amylase
Students examine what amylase is and its history. In this digestive instructional activity students study the effect amylase has on starch and how temperature affects the rate of activity.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Limiting Reagent
Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...
Curated OER
Lose Some Weight- Evaporate!
Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...
Curated OER
Enzyme Lab
Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.
Curated OER
Glucose Factory
Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.
Curated OER
Ohm's Laws
Students explore the relationship of resistance, voltage and current in series and parallel circuits. Then they discover Ohm's Law by constructing series circuits with one resistor and putting the resultant resistance, current and...
Curated OER
Electroplating for Corrosion Protection: Redox in Action
Students define what a redox reaction is. In this chemistry activity, students electroplate some wires in the lab. They research the application of electroplating in the real world.
Curated OER
Electrical Circuits And Switches
Learners design and draw circuits with batteries, small light bulbs and common household conductors. They build and test the circuit then modify it so someone who couldn't use their hands could turn the circuit on and off.
Curated OER
Where My Peeps At?
Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.
