Students measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

Students take a crushed rock and sort the remains of the rock minerals into different categories based on the different properties. In this sorting lesson plan, students learn what makes up a rock and how to sort something into categories.

Students show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity in order...

First graders study plants and animals and how they depend on one another. They also study that plants give energy to animals and provide oxygen needed for life. Finally, 1st graders give examples of the roles plants and animals play...

Students explore the mesosphere and lower thermosphere globally and achieve a major improvement in our understanding of the fundamental processes governing the energetics, chemistry, dynamics, and transport of the atmospheric region....

In this growing tomatoes worksheet, learners experience and participate in the process of growing tomatoes over a three or four month span of time. Students follow six directives in producing tomato plants.

Pupils explore the characteristics that distinguish living things from nonliving things. Students examine video clips and still photographs to gather evidence and develop criteria to decide if something is living or nonliving.

Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.

Young scholars explore a hardwood forest. In this forest ecology lesson, students examine the diversity and animals and plants as they explore their habitats at Poricy Park Conservatory. Young scholars determine how biodiversity and...

High schoolers discover how toys often illustrate fundamental physical principles. The toy drinking bird is an example. The challenge for you in the lab is to discover why the drinking bird functions.

Middle schoolers use the blooming of tulips as a tool to measure spring's journey north. They predict when tulips bloom at 13 selected Journey North gardens in various geographic regions.

Students observe and describe animals in the local environment. They recall information about different animals they have seen. They read and discuss their favorite animal books.

Eighth graders record the temperature change of the beakers. In this general science lesson, 8th graders create their own data table for recording observations. They discuss experimental results and cite real life applications.

Students experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...

Learners put items in a plastic bag and watch the effects of composting. While completing the experiment, students answer questions and ask permission to start their own compost pile at home.

In this lesson students will create and investigate a simple model of the water cycle. Student sheets are provided in English and in Spanish.

Demonstration helps students understand the water cycle.

In this activity, you will investigate some of the processes that make water move in and out of the atmosphere by making a miniature water cycle model inside a plastic bag.

This Weather, Climate & Water Cycling unit has students investigating small-scale storms, mesoscale weather systems and climate-level patterns of precipitation.

In this science activity, students investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the water...

In this water cycle activity, students investigate the evaporation process by participating in an outdoor evaporation experiment held on the school grounds. Students will determine where evaporation takes place the fastest and how nature...

Students will listen to a story about the water cycle, observe how water droplets form on a glass of icy water, then draw and label a picture showing condensation.

Activity provides an understanding of the water cycle.

In this teacher directed inquiry indoor lab students collect snow in a cup. They will estimate how much water will be in the cup after the snow melts. Students will then make predictions about what will happen to the cup of water. After...
