Students are introduced to the Munsell System of Color Notation that is used for direct comparison of soils anywhere in the world. They become familiar with hue, value and chroma notations, identify colors that act as clues to the...

Looking for some simple multiple-choice questions for an upcoming biology unit on animals? This worksheet features 7 clearly worded questions, each with 4 possible answers. Topics include adaptation, camouflage, ecosystems, animal...

Young scientists access the EARTH Web site in order to engage in this lesson life forms found in the ocean. Student groups of 3 - 4 choose one set of deep-sea organism images. The groups decide how they would classify their organisms and...

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...

Students analyze art as a cloud pattern activity. In this cloud and art lesson, students view April Gornik's painting The Back of the Storm and make connections between science and art. Students observe cloud patterns for one week and...

In this rock cycle worksheet, students study the diagram of the rock cycle and explain how minerals originally in magma could travel through the cycle. Then they identify how these minerals end up in each of three main classifications of...

In this weather worksheet, learners identify the type of vegetation found in particular regions across the United States. Then they list the six groups of climates in the Köppen Classification System. Students also describe the...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

High schoolers explore igneous rocks by observing rock samples and considering cooling rates and composition. The third installment of a five-part geology series culminates in an activity where learners use igneous rock...

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Here is a fascinating topic: the upwelling of ocean waters. Oceanography pupils learn what mechanisms cause upwelling, types of upwelling, and the effects on marine life. Colorful satellite imagery and informative diagrams bring this...

Here is an outstanding presentation on protista. It lists general characteristics, and then moves on to describing three different categories of protists. For each, viewers learn physical features, behaviors, and means of reproduction....

Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

Students demonstrate an awareness of the types of simple machines and classify common objects in relation to the simple machines involved.

Learners explore the three main organismal divisions. Students classify organisms by invertebrates, vertebrates, and plants. They observe the differences and similarities between these groups.

In this classifying worksheet, students read about grouping similar objects into categories based on similarities. They determine how the groups are related and they draw a diagram showing categories and subcategories.

Students classify and record objects they find "underground." In this observation lesson, students dig into bins filled with soil and encounter various objects such as bark, twigs, etc. Students classify their findings.

Students identify tree species by their leaf characteristics. In this dendrology lesson, students learn leaf vocabulary and collect leaves. They identify the leaves using the leaf characteristics and the vocabulary that they learned.

Students examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino acid...

Students participate in an interactive game to review how living things are classified.

Fourth graders describe the various kinds of soils and how plants and animals are affected by them. They describe the baic needs of plants, scoring at least a 3 or 4 on a 4-point rubic. Students are able to predict and/or infer what...

Students explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.
