When it comes to teaching science in the classroom, the best bet is usually hands-on learning. Science experiments are often thought of as challenging or difficult, but they can also be a lot of fun. Lots of 3rd-grade science lessons ask students to make an observation, do research in a journal, and design and carry out their own experiments by using the scientific method.
The science projects below are not only quick and easy, but they are also very engaging. Some of the projects need students to utilize a kit and conduct an experiment at home, while others require them to create a model activity. These exercises can be completed in class or over the summer with the assistance of parents. Before beginning any project, whether at school or at home, always get permission from your teacher.
1. Fossil Making
Students will learn the basics of paleontology, the study of prehistoric life on earth. Fossils are preserved impressions or traces of plants and animals from thousands and millions of years ago. It is important to understand that fossils come in many shapes and sizes. Some are very hard to see with the naked eye; others are so big you can see them from space, like the Grand Canyon.
2. Break the Rules of Gravity
Are you ready to defy gravity? You will be with this cool science project. Balloon rockets are a blast and are sure to wow family and friends. The main ingredient is hot air, also known as fire! Students will record their observations while they’re doing the experiment. In the end, they’ll have a final product that’s fun and educational.

4. Salt for Fall
The following salt crystal project is great for fall. When creating this activity, it is important to understand that the color of the crystals will be determined by what type of food coloring you use. Take note that adding a little bit of water to the salt makes the crystals form faster.

6. Center of Gravity
This is a project about sturdiness. Students will devise an experiment to see how much weight behaves differently depending on where it is positioned. After that, students will conduct a range of experiments, constructing their own and obtaining the necessary measurements to learn how different materials react to forces.
7. Marble Racetracks
This project is an enjoyable one that will have students doing experiments that will demonstrate gravitational force. Students can try out different shapes and sizes of areas to see which ones make the marble move faster or slower.

Catapults are a great way to challenge the mind and eye. First, you will need to choose which material you’ll be using for your catapult. The most common is wood, but other popular materials used in this project include cardboard, rubber bands, and duct tape. Next, you’ll need to choose an end for the projectile by picking between the long and short-range. The longer the range, the harder it will be to launch your arrow, but the farther it will travel.

13. Explore Water Temperatures
There are a lot of different projects that can be done with water. Water is both a liquid and solid; it’s also the substance that covers most of our planet. Understanding this substance is important to students who are interested in ecology, biology, and environmental science, as well as other sciences like chemistry and physics.

14. Water Balloon Buoyancy
Water Balloon Buoyancy is an experiment that allows students to learn about density and buoyancy. Using several water balloons, students can measure how much they weigh in different sizes of balloons. This experiment can be done at home or in the classroom.

15. Erosion Exploration
Erosion is essential to learning about geology and the environment. Erosion can cause problems for farmers when their land becomes too dry and their crops start dying. Once that happens, the farmer must make an observation about what happened, research his findings in a journal, and then come up with a plan to prevent erosion.

16. Water Pressure Experiment
A water pressure experiment is an activity that helps students understand that water is a lot like gas and air. Water pressure, like gas and air pressure, can create movement. The more water you pour into a container, the more pressure you’ll have, and thus the more movement you’ll create.

17. Temperature and Density Correlation
A temperature and density correlation is an experiment that asks students to understand how temperature and density are correlated. All liquids expand as they get warmer, and all solids contract as they get older.
