Students explore botany by participating in a seed experiment. In this plant nutrition lesson, students define several science experiment vocabulary terms like observation, treatment, and replicate. Students utilize soaked seeds in a...

How do sugar and salt affect celery's mass, width, and flexibility? Using simple household ingredients, young scientists will perform a controlled experiment to find out. The lab is scaffolded through a worksheet, but there are no other...

More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

Fire in the hole! Thrill your classes as they see what it's like to fire a cannon ball. Scholars practice aiming a cannon ball by altering first the firing angle, then the velocity, and finally both simultaneously. Can they discover the...

Twelfth graders study the relationships of the 3 variables in Newton's Second Law. They design an experiment to test the relationships among the variables. Students work cooperatively with members of a team. They also analyze data to...

For this physics review worksheet, students compare experimental variable, simple machines, and Newton's Laws. Students calculate kinetic energy, work, power, speed, and velocity. Students review conduction, convection, and radiation....

Students experiment with point graphs. In this math lesson plan, students are divided into groups and perform an experiment to see how high a ball bounces, recording their results on a point graph. Students then answer provided questions.

Students study the variables that affect transportation of shipments and the factors that affect deterioration of a perishable product.  In this transportation lesson students discuss the pros and cons of team driving. 

Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.

Students become familiar with the variables that control Earth's solar energy supply. They explore the source and nature of solar energy, the genesis of radiation, and the structrue of the Sun, gas spectra are observed and sample...

Students experiment with solutions.  In this mixtures and solutions science lesson, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the different rates...

In this scientific investigation worksheet, students use "magic tubes" to make observations, hypothesize, study variables in experiments, write procedures, and draw conclusions.

Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...

Students design a track that keeps a ball in motion for 5 seconds or longer. In this designing lesson plan, students explore force, gravity, and cause and effect when it comes to science and building before building their own track.

In this rate of solution worksheet, high schoolers determine how quickly a solute dissolves in a solvent by testing one independent variable such as temperature, particle size or the amount of stirring. Students design their experiments...

Learners investigate the pH of the soil in which different plants grow. They design and carry out an experiment to determine the factors that affect the growth of a population of plants, identifying and controlling major variables...

Students observe that plants need air, food, light, and water to survive.  In this plant biology activity, students observe the growth and development of two plants, one is the control plant and the other is denied either air,...

In this scientific method worksheet, students complete a crossword puzzle given 21 clues about the steps of the scientific method. Topics include observations, hypotheses, variables, inferences, results and conclusions.

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

In this project instructional activity, students complete a formal write up of their experiments. This includes a rationale, a purpose, a hypothesis, their experimental design, materials, procedure, data tables with variables, graphs and...

Students discuss the value of sampling in science. They, in groups, map cricket movement in response to various stimuli and graph their results.

Students study the role of controls. They discuss variables and list conditions, that if not kept the same for both flasks, could effect the outcome of the experiment. They come up with most of the following: Amount and temperature of...

Students explore the breakdown of proteins. They cut wells in Jell-O and observe as the detergent digests the Jell-O. Students record their observations and take measurements.
