Students explore mixtures and compounds. In this lesson, students do an experiment to distinguish between mixtures and compounds. Students complete ten different phases of the experiment testing many different substances. Students will...

Pupils explore methods for reconstructing the past. In this forest succession lesson, students examine forest succession and how to read the land in order to predict patterns of change. Pupils will visit a historical site, act as an...

In this human reproduction worksheet, high schoolers will review the male and female anatomy and the hormones involved in the development towards sexual maturity. Students will also review the events that occur during the three phases of...

In this chemistry of ice cream worksheet, students investigate colligative properties and how they affect freezing points while making ice cream. Students answer short answer questions to determine if freezing is an endothermic or...

Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

Students examine how human produced emissions of carbon dioxide contribute to global warming. Using the internet, they research the future effects of global warming on the Earth. In groups, they discover ways to reduce daily energy...

Young scholars review the planets and major moons in the Solar System. In groups, they research and describe the various phases of the moon. They record their observations of the moon phases over a specific period of time and use the...

Third graders read books about the moon and discuss its perceived changes as it moves across the sky. They observe the moon over the course of a month and chart their observations. They discuss their observations and conduct further...

Sixth graders observe changes in the moon's appearance over a month and keep records of their observations. They write a plan for recording what they see, and a paragraph reflecting on what they have learned over the course of the month.

In this chemistry worksheet, students calculate the freezing point of a given solution. Students calculate the final temperature and state of the water in a given problem. Students solve several problems provided.

Students observe the tides in San Diego for one month. Using this information, they graph the tides on a chart along with the phases of the moon. They answer questions related to the graph to end the lesson plan.

Pupils discover the importance of a healthy diet during space travel and examine the physiological changes astronauts experience while in space. In groups, they develop questions to determine an astronaut's food intake and identify five...

Young scholars study the science of the moon. In this moon observations lesson, students study vocabulary associated with the moon, study a lunar calendar, and a phases of the moon's orbit around the Earth.

Fourth graders complete activities to study the sources of energy and forms. In this energy lesson plan, 4th graders discuss the origin of energy and define it. Students participate in several experiments to further study energy...

Middle schoolers examine specific characteristics of liquids through a hands-on lab activity. An experiment with teacher prepared viscosity tubes is conducted in which liquid identities are predicted based on data. A hypothesis is...

Students identify fossils. They identify evidence of change over time when given pictures of fossils to determine the proper sequencing. In addition, they determine evolutionary relationships by comparing embryonic structures.

Students explain that particle movement changes as a substance changes from one phase to another phase.

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

Science learners apply dimensional analysis to relate quantities in six different problems. They consider the cost of steak, a young man's growth rate, a medicine prescription, fuel efficiency, and more. This worksheet is a great way to...

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...

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...

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...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Young scientists discover that air is a mixture of different gases - mainly nitrogen and oxygen. The properties of some of the other gases found in oxygen are listed in a table, then learners must decide which one of those gases is...
