Why Circulate?
Lub-dub, lub-dub. Why does the heart beat? Why does blood circulate throughout the body? Life scientists find out how important circulation is for dissolving and dispersing materials by timing how long it takes for food coloring spread...
Baylor College
Heart Rate and Exercise
What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

Nature of Science and Ecology
Pupils identify the different biotic and abiotic components of an ecosystem. In this ecology instructional activity, students perform a case study on current environmental problems. They write a position statement about their chosen...
Curated OER
Taste Test
Third graders, in groups, complete a science lab in which they perform a blind taste test on eight different foods--some sweet, sour, salty, and bitter. They determine which parts of the tongue "taste" which kinds of foods. they record...
Curated OER
Egg Tempera Painting In The Renaissance
Young scholars explore the development of paint and paintings during the Renaissance. In a science lab, they reproduce the properties of egg in tempera paint and compare and contrast egg tempera paintings to oil paintings. Through...

Scientific Equipment Word Search
In this scientific equipment worksheet, students locate words related to science lab materials. A list of 21 words is provided for identification. An answer sheet is provided.
Texas Instruments
Measuring Air Pressure Lab
Your class can investigate the weather through an experiment. In this chemistry lesson, learners collect data on air pressure and relate it to the weather. They collect data with the TI containing a barometer probe.
Curated OER
Endothermic and Exothermic Lab
In this endothermic and exothermic reactions worksheet, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute...
Curated OER
Parts-Per-Million Concentration Lab
Students develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...
Curated OER
Eutrophication Lab
Middle schoolers examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden...
Curated OER
Erosion Lab
Eighth graders explore variables that influence the rate of erosion due to the 4 major agents. They work as a group and practice conducting experiments according to the scientific method. Students comprehend that communicating ideas...
Curated OER
Solubility Lab
In this solubility worksheet, students test a variety of polar and non polar substances to determine which ones will dissolve in vegetable oil and which ones will dissolve in water. Students collect data and answer 2 questions about...
Curated OER
Osmosis and Diffusion: Egg Lab
Students examine why diffusion and osmosis happen in an egg cell. In this diffusion lesson students demonstrate a semi permeable membrane.
Curated OER
Applied Science - Physics Pre-Lab
Students observe fluid motion. For this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.
Curated OER
Applied Science - Built Environment (6) Lab
Sixth graders look at toys in space. In this gravity lesson, 6th graders make predictions about what different toys will do with zero gravity. They watch a space video and see what happens to these toys in space.
Curated OER
Evolution Lab
Students examine the pattern of natural variation in a society. They examine Darwin's theory of evolution and analyze data. They use computer programs to graphically display the variation in organisms.
Curated OER
DNA Extraction Lab
Students extract DNA and test for its presence from unroasted (raw) wheat germ using a prescribed procedure. They modify the procedure to provide a less expensive, easier method. They also extract DNA from different available plant,...
Curated OER
Pendulum Lab in 9th Grade Physical Science
Ninth graders conduct experiments to determine what affects the rate of a pendulum's swing. Working in small groups, they identify an independent variable to study and create an experiment to test their hypothesis. When tests are...
Curated OER
Formula of a Hydrate Lab
In this hydrate worksheet, students find the formula of an unknown salt by determining the mass of water in the heated compound. Students burn off the water and record data to establish the final mass and formula of the hydrate.
