What would future archeologists learn from your scholars' personal belongings? Have them bring in a box of "primary sources" from their home. Discuss the difference between observations and inference, using some of your own items to...

Students observe how to distinguish observations form inferences.  In this examining inferences lesson students list observations relating to the activity and discuss the importance of them. 

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

First graders study that day and night result from shadows produced by Earth's rotation. Students work to show how shadows are produced, look for and identify shadows and observe shadows produced from different sources.

Students observe plants growing over time, measure specific plant growth, and gather and record data on plan growth.

Students observe an artifact and make an inference about the artifact's purpose. They are going to role-play as archaeologists by using artifacts to hypothesize about the lives of past people.

Learners predict outcomes of scientific experiment,.conduct a scientific experiment with control groups, and plant seeds to observe, measure, and compare growth across groups. They gather, record, analyze, and share data with other...

The task? Determine the how effective hospitals are at reducing the rate of hospital-acquired infections. The method? Data analysis! Using an open source software program, individuals use provided data and create scatterplots to look for...

Define parallel lines through transformations. The third lesson of 18 examines the result of the translation of a line. Two possible outcomes include coinciding lines and parallel lines.

Students identify cardinal and intermediate directions, recognize that models changes due to new or improved observations and technology, identify the major characteristics of the planets including their positions in the solar system,...

Eighth graders study the importance of cell division, compare cell division in prokaryotic and eucaryotic cells, identify the stages of mitosis and recognize meiosis in reproductive cells.

Students identify the effect of light on objects. In this scientific inquiry activity, students use a chart to write a hypothesis about what will happen when colored construction paper is left in sunlight. Students observe and discuss...

Third graders explore the capillary action of plants. They discover what makes paper "grow" when water is dropped on it. Pupils observe how paper reacts as it absorbs water. Students use a variety of saturate solutions to grow crystals,...

Young chemists learns about acids and bases by coming up with a solution that will test for each. They also access the Internet to perform research. They are encouraged to contact students in other schools by conducting the experiment at...

Students discuss the importance of not making assumptions when only little information is known. With a partner, they complete a worksheet in which they only look at them to figure out what they like, etc. Next, they ask them the...

Students construct parallel lines using a protractor and a straightedge. In this geometry instructional activity, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

Students observe fault movements on model of the Earth's surface, find fault movements associated with different types of plate boundaries, research examples of non-plate boundary faults, and research and report on the types of faults...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

Students play a game of questioning with the teacher after reading silently a beginning passage of text. They and teacher request specific information from each other until students are able to summarize and predict the outcome of the...

Fourth graders explore, examine and study ceramics, a medium of historical importance to China. They review the advanced technology of the early Chinese civilization and are introduced to the scientific method of inquiry and make...

Learners investigate the relationship between angles of triangles. In this geometry lesson, students identify properties of right and non-right triangles. They differentiate between vertical and supplementary angles.

Third graders take a walk around the outside of the school and examine their clothing to see if they picked up any seeds while on their walk. They discuss how seeds travel and how a new plant thus can form. They then observe root...

Students develop a scientific model of gas behavior. In this gas lesson plan, students observe different balloons filled with different densities of gases. They complete an activity where they model the behavior of gases using marbles, a...

Learners explore the role of enzymes in chemical reactions. In this enzymes lesson plan, students use hydrogen peroxide and manganese dioxide to observe a chemical reaction. Learners observe the rates of reactions of chalk, hamburger,...
