Students explore several examples of cardiovascular diseases. In this anatomy instructional activity, students explain why physical fitness is very important. They count their pulse rate and record them on a data table.

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

In this charts, graphs and tables worksheet, students view 3 different types of visual representations of data, make a list of 20 items and decide how the items can best be put together in groups to make a graph, chart or table. Students...

Students collect survey data on the prevalence of asthma in a community. They summarize and display the survey data in ways that show meaning.

In this astronomy worksheet, students participate in an activity using the parallax effect to measure star distances. They record their information in a data table then complete 5 fill in the blank conclusion questions.

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

Harness young scientists' knowledge of genetics with an engaging science activity. Students start by flipping a coin to determine the genotypes and phenotypes of two parent monsters, before using Punnett squares to...

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Does the crystal structure of a hydrated solid determine the proportion of water absorbed, or does the application of heat change the absorption? Scholars experiment with both variables to determine the answer. They add their collected...

A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...

Students calculate how much mass is lost and gained by Antarctica yearly. In this earth science lesson, students graph and analyze data from the given handout. They explain how this affects the world climate.

Finally, a activity that involves more than filling in some blanks. Your budding ecologists must graph and analyze three sets of data, then synthesize the information as they think about the impacts of plant reproduction on insects and...

There is a chart to complete with results of the titrations for the 14 different pH indicators.  There are also nine questions for data analysis, and then four problems requiring equations, molarities, and pH values.

How can one easily classify metals, nonmetals, and metalloids? Pupils answer this question as they experiment with unknown substances and perform tests on conductivity, brittleness, and malleability to determine...

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson plan in a short unit on climate change and the ocean helps environmental scientists answer these questions. After...

A neatly formatted outline of the steps of the scientific method can be used as a reference sheet for your future science fair participants. For each step, you will find a few guiding questions or points to remember when working on...

Due to the isolation of seamounts, their biodiversity offers a great deal of information on the development of biological and physical processes. Pupils use simple cluster analysis to rate the similarity and differences in biological...

How do scientists know they're right? Truth be told, they don't always know. Explore the scientific process using mystery tubes in an insightful activity. Young scientists discover how to approach and solve problems in science, how ideas...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

What happens to stars as they get older? A simulation takes pupils through the life cycle of stars based on their masses. The resource introduces the Hertzsprung-Russell diagram and the common relationships and life cycle patterns observed.

Psychologists use statistics? Scholars investigate the research behind the methodology of statistical analysis. Using hands-on practice, case-studies, and scatterplots, they complete various tasks to understand the very roots of high...
