Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

In this significant figure worksheet, students read six diagrams of a graduated cylinder to the proper number of significant figures. They then go to twelve lab stations and record the proper measurement to the appropriate number of...

In this measuring chemicals worksheet, high schoolers investigate measurements of an aluminum slab including the length, width, height, mass, volume and density. They do the same for a piece of aluminum foil and they compare their...

In this density worksheet, learners measure the mass and volume of assigned objects and calculate the density. They then find the mass and volume of two objects given their densities and volume and mass respectively.

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,...

Is butter better? In terms of saturation, young chemists find out! Using titration methods, they will compare the degree of saturation of butter with that of margarine. Knowing the unsaturation, they can make conclusions about the...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

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 quantitative analysis activity, students perform a lab to determine the amount of acetic acid in vinegar by doing a titration. They use an indicator phenolphthalein to determine the endpoint of the titration.

In this porosity and permeability worksheet, students experiment with different types of soils such as sand, gravel, pebbled and rocks. They put each soil type in a beaker and pour water in being sure to measure the amount of water they...

In this absolute zero worksheet, 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 data. They...

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 science worksheet, students identify and explain what each unit represents and how much each one equals. Then they use a metric ruler to locate each measurement and write it on the line. Students also locate the distance between...

Some background information about density and Newton's Laws of gravitation and motion assist pupils in the following experiment. The procedure will help them further their understanding of gravity, pendulums, and a drop-ball experiment....

Estimating Errors in Chemistry is a detailed handout that illustrates the importance of calculating the percent error when working in the chemistry lab. There are no actual problems to solve, just notes and examples of calculations. Hand...

In this observing and identifying matter worksheet, middle schoolers use a cookie in a bag and list 10 different descriptions of the cookie. They draw and label their cookie and given the cookie in the bag to their teacher who mixes all...

If you have a set of six various metal rods, you can use this lab activity to challenge science students to calculate their densities. They will use a triple beam balance to measure the mass and the micrometer and ruler determine the...

This is a great worksheet with an infographic to assist your learners in categorizing matter into mixtures and non-mixtures. Information is given about the metric system of measurement. Your young students match 13 terms with their...

In this density of pennies worksheet, student conduct an experiment to determine the metals used in the core of pennies made after 1983. High schoolers design their own experiments using a balance and graph paper to determine the density...

In this food energy worksheet, students review calories and how calories are determined. Students calculate how much thermal energy it would take to raise certain volumes of water a certain number of degrees. This worksheet has 3 word...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

In this science worksheet, students use the diatoms present in water in order to test water quality and perform data collection and interpretation.
