Young scholars determine the amount of sugar in various types of gum. They chew a piece of gum until it loses its flavor and leave it to dry in order to weigh it and determine the amount of mass lost, and describe an experiment to...

In this chromatography worksheet, students are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.

Middle schoolers build an apparatus to look at how yeast cells grow by converting food to energy. They observe yeast both with and without food and see how yeast produces carbon dioxide.

Students make a water sampler and use proper techniques to collect water.They write a essay explaining the inter-relationship of factors such as temperature, pH, dissolved oxygen, nitrates, and phosphates in a lake that might cause a...

Young scholars become familiar with the structure and use of dichotomus keys. They demonstrate a comprehension of the fundamental principles of taxonomy by classifying organisms from a local ecosystem. Students are introduced to the...

First graders taste a variety of items and record a full sentence about the way they taste.  In this taste buds lesson plan, 1st graders predict and then taste various items.  Students draw a picture of the tongue and show the...

Fifth graders observe and identify the differences between chemical and physical changes. In small groups they mix different substances together in glass beakers, and identify which had a chemical change, supporting their statements...

Students work together to complete different building challenges. They use prior knowledge to build tunnels and different types of bridges. They share their creations with the group.

Students design a prototype game as they simulate being game designers for a major corporation. They base the game on the major body systems.

Students investigate cohesion, adhesion and surface tension through observations and lab experiments. In this cohesion, adhesion and surface tension lesson plan, students rotate to 5 stations around the room and experiment at each...

Students conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

Students perform paper chromatography to determine pigments in plants. In this paper chromatography lesson plan, students isolate leaf pigments, prepare a chromatogram and place their chromatogram in a solvent to separate the pigments....

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

Students measure irregularly shaped bones, once using a variety of measurement methods and tools, and then again using standard conventions and metric tape measures. They explore firsthand that standardizing data collection makes...

Students explain how a feedback control system works. They model a feedback control mechanism for controlling water level by observing the flow rate of water in a cylinder. In addition, they graph their data. Script for lesson is included.

Fifth graders observe and conduct a variety of experiments to differentiate between physical and chemical changes. They mix cabbage juice with different liquids and record their observations on a chart. Students write down their...

Fourth graders design and launch rockets.  In this rocket lesson, 4th graders observe the changes in outcome caused by size and fuel variables. Students navigate the NASA website to learn the parts of a rocket. Students load the...

In this convection currents worksheet, students draw, cut and decorate a spiral snake on a sheet of paper. Students attach a piece of thread to its head and hang it over a hot radiator and watch the snake spin as the warm air rises.

Students predict traits of future offspring. For this biology lesson, students study karyotyping to predict genetic disorders. They research an assigned karyotype and present information about it.

Students design a candy bag in order to create one that can hold the greatest weight without breaking. They create a model after the design is put down on paper. The bag is then tested with different weights and redesigned as necessary.

Students use the scientific process and their knowledge to obeserve, predict, and test their predictions under controlled conditions to verify their predictions and then make sense of these predictions. They also graph, write...

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Young scholars experiment with local lake water to determine the health of the lake waters. They explore the human impact on the lake water, hypothesize and share inferences in a scientific report.
