Great Lakes Ecology
High schoolers are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier...
Curated OER
Bird Brained?
Students identify general abilities that indicate animal cognitive intelligence. In this biology instructional activity, students create an intelligence testing challenge for ravens. They compare its ability to that of a crow.
Curated OER
Foodborne Illness Outbreak Investigation
Students demonstrate how epidemiological investigations of outbreaks are performed. They illustrate the principles of hypothesis formation and testing by epidemiologic study in the setting of an acute foodborne disease outbreak.
Curated OER
Climate And the Greenhouse Effect
Students demonstrate the greenhouse effect. They recognize that relatively small changes to our environment can stimulate significant climate changes. They determine that the "scientific method" is a process of testing hypotheses and...
Curated OER
Fortune Teller Fish
Students demonstrate how to create and test a hypothesis. They design an experiment and set up a variable, experimental group and control group.
Michigan Sea Grant
Water Quality
Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.
Curated OER
Acid and Base Testing 2
Students design and conduct an experiment on unknown solutions after studying descriptions of indicators and the way in which they identify acids and bases. Students must gather, organize, and analyze data as well as make inferences...
Curated OER
Science Experiments - The Low-down
Third graders discover the process thinking about science experiments, and why they are important. They work in small groups using incline planes and a small toy car to design one scientific question that can be answered through...
Curated OER
Vitamin C Testing
High schoolers determine which of three beverage samples contains the most vitamin C. They then apply their knowledge to an additional situation. Students use beverages that have a large, definite difference of vitamin C content to...
Curated OER
Starch and Sugar Testing 2
Students design and conduct an experiment to determine which of three solutions contain starch or sugar. This task assess students' ability to make simple observations, design simple experiments, utilize indicators, and make generalized...
Curated OER
Starch and Sugar Testing 1
Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...
Curated OER
Food & Science - How Healthy is Your Diet?
Learners experiment with various foods to determine fat and starch content. They rub jam, peanut butter, bananas, and other foods in a small circle on a piece of paper, and observe the results. If there is a high fat content in the...
Curated OER
The Testing of the Feebleminded Immigrants
Young scholars examine the intelligence testing of Henry Goddard during the early 1900s. They discover criticisms that are still occuring today. They analyze how science and technology is contributing to this practice.
Curated OER
What is Dissolved Oxygen?
Students experiment with the LaMotte Winkler-Titration Test Kit to try to answer the question of what is dissolved oxygen. They explore all the possible ways to test for dissolved oxygen and brainstorm all the obstacles that can affect...
Curated OER
Which Wrap Is Wrapped Right?
Young scholars investigate the integrity and strength of different types of food wraps. They test the wraps and create a graphic organizer for the data. Once it is organized then a lab report can be written. The lesson plan contains...
Nuffield Foundation
Identifying the Conditions Needed for Photosynthesis
Budding biologists often ask how scientists know what they do about different topics. In the lab described here, they have a chance to find out first-hand about the requirements for photosynthesis. Three sequential investigations are...
