In this law of action and reaction worksheet, students build a bubble powered rocket using a film canister, paper and effervescing tablets to create bubbles inside the canister of the rocket. The pressure inside causes the canister to...

In this earth science worksheet, students use the clues given at the bottom of the sheet to solve the crossword puzzle on mineral and rocks. They identify the various types of rocks formed and specific examples of these rocks.

Students observe and describe a chemical reaction. In this chemistry lesson, students record observations of the materials they will be using, then follow a written procedure to perform the experiment in a baggie and record their...

Students identify that yeast are a single celled fungi that are a great model organism for studying respiration in the classroom. They also fill the bulb of a disposable pipet (eyedropper) with yeast, then submerge the pipet in a test...

Third graders brainstorm and record all their responses about what they know about bubbles. They discuss what they know about bubbles and what they would like to know about them, keeping their responses on a second sheet of newsprint....

Fourth graders participate in a demonstration lesson using bubbles in which they determine that air fills the bubbles. Next, they work in small groups as they they experiment with the properties of air at separate work stations. After...

You have to crack a few eggs to make a good engineer! Working in small groups, young scholars design, build, and test devices that protect an egg from breaking when dropped from a ladder.

Young scholars conduct an experiment to determine the percentage of sugar in various types of gum. They weigh the gum after chewing it to determine the amount of mass lost from each piece of gum, analyze the data, and create a graph of...

In this scientific method worksheet, students perform an experiment to determine the speed at which they can chew a piece of gum. They record data, calculate speed and answer reflection questions.

Students assess what a dichotomous key is and how it identifies objects in a group through a process of answering yes/no-type questions about certain objects. They examine an interactive graphic key on sea turtles and then create their...

You're on solid ground if you decide to use the resource. A simple activity has young engineers investigate the problem of liquefaction. A battery placed on dry sand will stay standing—but not if scholars add water to the cup.

Four demonstrations with the Van der Graaf generator are delineated for you to share with your science classes. Instructions, explanations, and safety precautions are included. However, a background explanation of the static electricity...

First graders are read a story about the various stages of matter with a focus on gases. Using a ziploc bag, they capture as much air as possible and discuss how it takes up space even though it is invisible. To end the lesson, they blow...

Students engage in a instructional activity which demonstrates that volcanism is the process whereby materials formed inside the Earth come out onto the surface. They participate in a simple, yet effective, activity which demonstrates...

The concept of electrophoresis and how it can be used to track sections of DNA that have been spliced is introduced in this slideshow.  There are a few grammatical and spelling errors, but overall the slides are nicely presented.

Students investigate the concept of a compass and it has been used in the past and in modern times. They practice using it in the wilderness in order to test its importance in various exploring activities. Each activity is accompanied by...

Students examine the physical properties of waves to explore the word crest and trough. They use toys to study waves in air, water and light.

Students examine the correct attitudes and poster for a concert. In this "Singing for Animals" lesson, students created charts to diagram information about the homeless animals they were singing for. Students used correct diction and...

Using a simple method, learners explore gravity, cohesion, and adhesion. They perform an experiment in which they determine how many drops of water can fit on a penny. Afterwards, they discuss their results.

Tell case study story of EMS-induced chlorophyll polka-dots in C-ferns. You will need to be familiar with the experiment, as there are some slides that have only photos, no text and no presenter's notes. By using this presentation,...

In this changing crust worksheet, students use candy bars, licorice sticks and bubble gum to simulate the 3 types of forces that change the Earth's crust. These include compressional forces, tensional forces and transversal forces. The...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...
