Summer is almost over but you don’t have to die out of boredom during the rest of your vacation. Here are AHA-MAZING! science projects that you can try at home!
Tissue Box Catapult
You don’t have to buy anything for this. Lahat ng pwede mong gamitin ay nasa bahay lang! Be your own engineer.
What you need: An empty box; 3 unsharpened pencils; Rubber bands; Hole punch; A plastic cap; 1 pipe cleaner; Scissors
What to do: Cut down the top portion of the box if covered. Punch a hole on both sides of the box then use the rubber band to attach the pencils together like a cross and insert it in the box. Attach another rubber band to the end of the pencil. Punch another hole at the end of the box and pull the rubber band through. The trick here is that this is going to be the power of your rubber band.

Baking Soda and Vinegar Powered Car
Begin a race against time using a baking soda and vinegar powered car. Using the right chemistry, you can play a game with your friends! Bring out the chemist in you.
What you need: 1 Empty bottle; Baking soda; Vinegar; 4 Bottle caps; 2 Barbecue Sticks; Hot glue gun
What to do: Attach the bottle caps to the barbecue sticks to become the wheels of the car then glue it to the empty bottle that will act as the car. Punch a hole to the cap of the bottle then put baking soda inside the bottle then pour the vinegar. Shake the bottle then let the race begin! The chemical reaction of the vinegar and the baking soda will act as the power of the toy car.

Kaya ba ng patatas magpailaw ng bumbilya, beshie? Let’s find out using this experiment! This is your little step to that electrical engineering career.
What you need: 2 large potatoes; 2 copper coins; Three 4” pieces of thin copper wire; Two galvanized nails (nails covered in zinc); 6 alligator clips; Small knife; 1.5 volt light bulb
What to do: Insert a copper coin and a galvanized nail to each potato. Wrap a copper wire to an alligator clip then attach it to the coin. Wrap another copper wire to the galvanized nails then connect both ends of the wire to the coin and the galvanized nails using the alligator clips. Attach another end of the copper wires using the alligator clips to the lightbulb and see what happens!

DIY Lava Lamp
Chemical reactions are the best! With just a few household things, you can make your own lava lamp!
What you need: An empty bottle; Vegetable oil; Water; Food coloring; Alka-Seltzer Tablets
What to do: Fill the empty bottle with water and vegetable oil. Add drops of food coloring in the mixture then drop alka-seltzer tablets and watch the magic of the burst. If done, you can add another tablet of alka-seltzer or put a flashlight under the bottle to see it glow!

Homemade Human Lungs
This isn’t as gross as it sounds, trust us. In this experiment, you will see how the lungs perform their work when you breathe!
What you need: A plastic bottle; A straw; An elastic band; Scissors; 2 balloons; Modelling Clay
What to do: Cut the bottom of the bottle then attach a balloon with its half snipped. Attach a straw at the other balloon then put it in the nck of the bottle. Make sure that the straw would not fall out by putting clay around the neck but ensure it doesn’t crush the straw. Hold the bottle then pull the bottom and check what happens!
