Third graders observe insects in a number of habitats. They recognize which insect characteristics are adaptations to their habitats.
Curated OER
How Can We Extract Human DNA?
High schoolers perform an experiment in which they extract DNA samples from hair samples. They follow a set procedure to extract the DNA and complete summary questions.
Curated OER
What Is In The Cup?
Young scholars investigate the mixtures of solutions. They utilize cups filled with bases and acids. Students test and determine the pH of each cup. The multiple cups are compared to each other in order to chart acids and bases according...
Curated OER
Soil Organisms
Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...

The human barometer
Middle schoolers read the story: 9-year-old girl dies on railway line. They engage in the 'Human Barometer': Collect a range of names of dangerous activities from the class. For example: skateboarding, waterskiing, bungee jumping,...
Curated OER
Properties of Liquids
Seventh graders explain that liquids are made up of tiny particles and how these spaces allow other particiles to fit in between larger particles. They then plan and carry out simple scientific experiments.
Curated OER
Enlightening Explorations, Part II
Sixth graders review their results from the previous experiments. After viewing a kaleidoscope, they make their own pattern on paper and describe the role of light. To end the lesson, they examine light being relfected and refracted and...
