Here’s a list of 15 fun and eye-opening science projects and experiments you can do with your 7th grade class this month.

• Real Smile or not

This fun project involves students attempting to tell the difference between a fake and a genuine smile. This warm facial expression can easily dupe one to fall for someone who isn’t genuine. Therefore, learners will employ several volunteers to demonstrate genuine smiles from the fakes.

• Left or right paw orientation

Animals, like humans, have limbs. However, do they feature similar left or right-handedness as humans? This project will seek to discover this orientation in different animals.

• Echolocation in bats

Bats are uncharacteristic animals that inspire awe and fear in most people. They rarely use their sight and are mostly active at night, and you’ll be mistaken to think that they are terrible navigators. However, bats have an uncanny hearing ability that learners can learn about while conducting this experiment.

• Corrosion-resistant metals

While metals are sturdy materials, they are not impervious to the forces of nature. Different materials get worn out when exposed to the environment. This experiment will investigate how air, tap water, and saltwater affect various metallic solids while determining the most resistant to corrosion.

• Smoke detectors 

Learners will try out two main smoke detectors to find out their operating mechanism. This experience will demonstrate the effectiveness of ionizing and photoelectric smoke detectors.

• Robotic motions

Learners in grades 6-8 will be able to construct a robot to investigate how it moves. They will fit sensors for sound and touch and release them inside a maze to find out whether the machine follows a sequential or random motion.

• Repurposing

There are a lot of waste products that could be repurposed into useful items. Learners can attempt to find alternative uses for several items like batteries, carton boxes, and mattresses in an attempt to clear environmental waste.

• Constructing a Gauss rifle

Learners can use magnets and ball bearings to build a Gauss rifle. After that, they can investigate the impact of the magnet on the projectile speed and range and whether more magnets would benefit the rifle.

• Smart medicine cabinet

There are many Americans who are on medication for different ailments. This project gives learners an opportunity to construct a smart medicine cabinet that will eliminate forgetfulness by those taking different medicines.

• Grow the best and the largest crystals

It doesn’t take much to create a crystal, and learners can attempt to grow the largest pieces. The catch, however, is to find out the ideal temperature conditions needed to cultivate sizeable crystals.

• Cooling a soda fast

Everyone has encountered a warm soda during a hot day that just won’t cool down. To avoid this, learners can try out various cooling mechanisms on a can of soda and find out the fastest way to drop those degrees.
