In this science worksheet, 5th graders complete multiple choice questions about flight, astronomers, measurement, temperature, and more. Students complete 25 questions.

In this absolute zero learning exercise, students experiment with a closed-end syringe and a ice bath and boiling water. They record volumes of gases in the syringe as well as temperatures of the water and they plot their experimental...

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

Explore the properties of solutions with a lab activity. Chemistry fans determine the boiling point of water, add salt to create a solution, and then repeat the process four more times. They design their own data table and then graph the...

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...

In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

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...

In this measurement and safety learning exercise, students find the terms in a word search puzzle for 13 statements about the SI units of measurement, the prefixes for the units and measurements of mass, length, and volume. They answer 2...

In this heat of formation worksheet, learners determine the heat of formation for magnesium by combining 3 given reactions and using Hess's Law. Students then complete a data calculations chart for each reaction.

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

Mini mycologists plan an experiment to determine what affects the growth of mold on gelatin. A list of available materials is provided, but the procedure needs to be designed by the lab group. A data table is also provided in...

In this calorimetry lab, students apply the information read about a calorimeter to conduct a scientific investigation. Students record their data in a chart. Students use the information from the chart to calculate specific heat of...

Are you nuts? An engaging experiment burns nuts to find their kilocalories. Young chemists analyze at least two different types of nuts with their experimental results versus what is on the package. The resource offers a great lab...

Chemistry explorers prepare a crystalline derivative and find its melting point. Once they discover the melting point, they can identify whether the substance is pure or an aldehyde or ketone. This outstanding laboratory activity helps...

Step-by-step laboratory instructions are listed so that chemistry explorers can consider the solubility of potassium nitrate. They combined their results with other lab groups' results and then graphed the data to display the solubility...
