The effectiveness of Antacids
Learners 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 determined...
Curated OER
Suburban Ecosystems
Students conduct simple sampling of plant and insect biodiversity at ground level in two contrasting environments of their own choosing. They recognize and record different species then compare and contrast species numbers in the two...
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.
Curated OER
Balloon Rocket
Students observe a balloon rocket and how it relates to Newton's Third Law of Motion. In this balloon rocket lesson plan, students make a balloon rocket out of balloons, clothespins, straw, fishing line, and duct tape.
Curated OER
Insulators
Students design and carry out an investigation to test which materials is the best insulator: they predict which way heat energy flows in a system and analyze the flow of energy in a system from one point to another and from one form to...
Curated OER
Pond-water Populations
Students design and conduct and experiment on algae, for a two week period, to answer the question "In your investigation, how does changing one factor affect the growth of organisms?"
Curated OER
Seed Growth
Students develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.
Curated OER
Stimulus/Response in Invertebrates
Learners design and conduct and experiment to determine how invertebrates react to an outside stimulus such as light and other stimuli. Student must develop a clear plan of action, collect data in an organized manner and analyze their...
Curated OER
Water-holding Capacity of Earth Materials
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...

Crime Scene Investigation: Hair Analysis Lab
Learners participate in a hair analysis lab. Using a digital microscope, students compare and contrast hair samples. They determine if the hair samples are human or animal. After completing lab results sheets, learners share their...
Curated OER
The Captain And Lake Wilmar
Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...
Curated OER
Let the Sunshine in
Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...
Curated OER
Paper Chromatography
Small groups of students perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. Students...
Curated OER
Water Regulation
Students use their basic knowledge of physiology to analyze graphical data of paramecia under diverse conditions. From the data analysis, Students develop explanations of the animal's response to the concentration of different solutions...
Curated OER
Are Fruits And Vegetables Really Made of Cells?
Pupils design and carry out an exercise to determine if a given fruit or vegetable is composed of cells. They dissect out sections of the fruit or vegetable, prepare stained slides, and make observations under a compound microscope.
Curated OER
Tadpoles
Students examine tadpoles at various stages of development. They make careful scientific observations and compare the changes that occur at five different phases of a frog's life.
Curated OER
The Nutritional Content of Food
Students are given three unknown samples and must perform two chemical tests in order to determine if the samples contains protein and/or starch. Students work with corrosive or toxic reagents.
Curated OER
Survival
Students determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's ability to perform an entire investigation. In this question the independent...
Curated OER
Classifying Materials
Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.
Curated OER
Density of a Sinker
Eighth graders determine the density of a sinker by first finding the mass and then the volume using a graduated cylinder. Students must write the procedure they use to find the volume of the sinker then apply their data to follow-up...
Curated OER
Aluminum Foil Boats
Pupils design a boat of aluminum foil and calculate the density of the boat. Washers are added to the boat until it sinks. Students then redesign boat to hold more washers and recalculate the new density.
