Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

Students examine abiotic and biotic factors. They define biotic and abiotic, categorize a list of items onto a Venn diagram, label various items from areas on the school grounds as biotic or abiotic, and diagram a magazine picture.

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

Are there factors that put some individuals at a higher risk for drug addiction than others? Learn more about the risk factors that may make some people more susceptible to addiction, as well as protective factors that help prevent...

In this lead blood levels worksheet, students use mathematics to determine the source of lead poisoning in children. They are given data, they analyze the data and they graph the blood level measurements vs. the mean blood lead level in...

In this orbital period worksheet, students solve 2 problems about satellites and their orbits. They determine how many days it takes for two satellites to be in "opposition", they find the least common factor between their orbit periods...

In this planetary alignments worksheet, students use 2 different methods to find out when planet alignments will occur. They use a three number series and they use least common multiples to find out when Mercury and Venus will align.

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

Students examine and calculate the percentage of potable water remaining on the earth. In this ecology and geography lesson, students brainstorm the main factors affecting water distribution. Students use mathematical problem solving to...

Students examine factors that control rates in mechanical system. They identify units associated with speed, calculate speed of moving object, identify units associated with acceleration, and calculate acceleration of moving object.

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Weather — there's more to it than meets the eye of the storm. With this resource young meteorologists learn about the basics of weather, including information about the factors that influence the weather, common weather vocabulary,...

What does your class know about GMOs? Are they savvy to selective breeding? Challenge young minds to engineer the greatest crop of all time using a hands-on genetics unit. Learners discover the good and bad details of selective breeding,...

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

Second graders observe images of prairie ecosystems and discuss the needs of living things. They create a prairie habitat in a closed jar to observe the water cycle and plant growth.

Students use temperature, cloud cover and other weather data from the S'COOL website to statistically analyze weather around the country. They use computers to calculate and graph standard deviations, means and modes of the weather...

Seventh graders participate in an experiment in which they calculate the time of decomposition of different materials. In groups, they fill bags with different materials and cover them in soil. After six months, they create a line graph...

Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

Bone up on bone density. The second installment of the seven-part series has pupils read articles on two different websites to learn about bone density and its measurement, as well as X-rays and other imaging tools. A quiz assesses their...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid tablet and water -...

In this water on planetary surfaces activity, students read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4 problems...
