After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

High schoolers set up a stream table, observe erosion, and record data on where various sizes of sediments settle. They draw conclusions as to what kind of sedimentary rock form in what locations.

Pupils are divided into 6 groups with each group rotating to a different lab. The labs can be run over the course of a few days; or spread out for a longer period of time.

In this lab report worksheet, learners answer ten questions by filling in a blank with the appropriate letter that corresponds to the part of the lab. Students determine where data goes, where observations go, where answers to discussion...

For this Cartesian diver lab, learners explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Learners make predictions of how changing the variable would change the...

In this chemical reactions worksheet, learners answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

In this Mr. Biando's lab worksheet, students define, study, review and discuss ten key terms associated with mammals and evolution. Students circle each key term in a word search puzzle.

The Blue Man Group, three bald performance artists painted blue, offer lessons designed to engage, intrigue, and excite the imaginations of all ages of learners. Groups craft a trickster tale, invent melodious mathematical instruments,...

Students recognize the concepts of the five general types of chemical reaction: combination, decomposition, single replacement, double replacement and combustion. They practice classifying chemical equations and determine the moles in a...

Pupils wear goggles and collect materials and then set up computer program to use the temperature probes. They insert the probe into the milk recording temperature every 30 seconds and then record the data on the table.

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the instructional...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Peer review of science laboratory reports? You bet! First, learners work in pairs to review a scientific article. Then they trade lab reports for peer review. The end result is the publication of a classroom scientific journal!

Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the...

Two laboratory problems are put forth for chemistry high schoolers. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

Students create a list of things that they do with electrical power. They then are shown a PowerPoint on "Basic Electrical Safety." Students evaluate electrical equipment, cords and situations for serviceability and safety problems. They...

Students use a balance and weigh a rock sample. They weigh the rock suspended on a sling in a glass of water. They tabulate the rock's density using the two weights and compare the density of various rocks of similar sizes.

In this biology worksheet, students complete a lab report being as detailed as possible. They identify the problem or hypothesis. Then they write the procedures and record their findings. Students also analyze their results, discuss, and...

Students engage in a lab which introduces them to fossils and paleontology. They examine eleven numbered boxes containing fossils which are related to the questions on this lab then answer questions on a lab sheet imbedded in this plan.
