Students design an experiment to test the variables involved in the hatching of the Bruchid beetle.

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Young scholars study maps of the United States to locate weather pals from a list of schools. They communicate with Weather Pal schools through the use of closed circuit TV. Using weather data collected in their area, they exchange the...

This very thorough lesson plan has young scholars collect all ingredients necessary and work in pairs to make ice cream using plastic bags. They take temperature readings and record them on the chart as well as record findings on the...

Young scholars examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Students use the internet to research Archimedes' principle of buoyancy. In groups, they summarize the principle and share it with the class. They also participate in experiments in which they test the principle and share their results...

Seeing how seeds grow into plants is such an enjoyable for students! They plant lima bean seeds and take pictures to record the growth of their plants. Students write in a journal to describe their daily observations of their plants, and...

Use the pump from a spray bottle to drive a model of the heart in action! In addition to modeling the function of the heart and blood vessels, aspiring anatomists also simulate arterial blockage. They compare the effects of increased...

Students gather data, make and share predictions about the time of sunrise ans sunset in their area. Patterns are analyzed and shared with students from other areas.

Seventh graders brainstorm about problems with a school track. They research different possibilities for a solution. They test different track materials with erosion, durability, abrasiveness and resiliency. They determine the area,...

Seventh graders define the term microbe. They identify the five main groups of microbes. Students give examples of ways in which microbes have impacted or currently impact human life. They create a hypotheses for where they expect to...

Second graders experiment identifying beetle emergence and exit holes in seeds, count them, look for beetle eggs with a magnifier and count how many beetle eggs they find. They then graph on a data sheet the findings from their research.

Students follow a bookmaking format to create a book and use it as a garden journal. In this science journal lesson, students follow book making directions to create a garden and science journal.

Students work with a partner to complete an inventory of their traits and compare and discuss their unique qualities. In this biology instructional activity, students determine percentages for the frequency of observed traits of...

Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...

Students examine and locate rainforests on maps, and research the patterns of their destruction. They develop a bar graph of rainfall and temperature data, write a journal entry, and research the people, animals, and plants/products of...

Junior archaeologists examine types of artifacts from the Bronze Age on the internet. In collaborative groups, they create a story about a ship from this period and then construct a model of the ocean floor after their ship has sunk....

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

Eighth graders conduct a "Length of Day Symposium." They complete a variety of activities and explorations regarding the earth's rotation, its revolution around the sun and the cyclic changes in climate and energy distribution on the...

Students observe the weather over a period of two weeks. They gather local weather data and calculate the mean and average figures from the data. They prepare a graph with their observations.

First-time physicists experiment with pendulums in this physics lesson. They vary the weight of the bob, record how long each takes to complete ten period swings, and then calculate the time for one period. They repeat the procedure,...

Fourth graders explore the characteristics of organisms and how these influence their ability to survive in particular habitats. Students perform experiments with types of bird beaks and graph their results. Students explore familiar...

Students examine the effect of temperature on how often crickets chirp. In groups, they complete the experiment and answer lab discussion questions. They create a graph of temperatures and the amount of chirps and discuss the results.

Students examine cell division and the process of mitosis.  In this cell reproduction instructional activity students grow yeast and observe the results, and learn about the career of scientific illustration.
