At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

In this DNA worksheet, students compare the DNA sequence of a human and a cow to complete 4 fill in the blank questions and 4 short answer questions.

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Students read about and complete question activities for the topic of relative dating. In this relative dating lesson, students read information for the topic and then complete two activities to further their understanding of geologic...

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Students examine Pascal's Triangle and attempt construct it on their own.  In this visual patterns lesson students explore patterns that exist in Pascal's triangle.

Give your pupils a front row seat at the biggest light show in the sky this year! In addition to admiring the total solar eclipse, young astronomers can explain the phenomenon with a little help from an inquiry-based lesson. The focus of...

Here is a good lesson on butterflies and caterpillars. After listening to The Very Hungry Caterpillar, young learners put cards that depict the life cycle of a butterfly in the correct order. There are some good ideas for center...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Fourth graders provide a habitat for live mealworms and observe their life cycle. In this animal life cycle and scientific inquiry lesson, 4th graders create a habitat for a live mealworm and observe and record related data as it grows....

Students examine the X and Y chromosomes. In this research lesson, students use the 5E lesson model as they read articles about human chromosomes then discuss their findings and opinions.

Students describe chemical changes occurring in hydrothermal circulation systems. They make inferences about the significance of these systems to ocean chemical balance compared to terrestrial runoff.
