12 Science Projects for 11th Graders (Ages 16 – 17)

Science Project 1: Homemade Volcano Eruption

• Baking soda
• Red food coloring
• Plastic bottle or small jar
• Clay or playdough to build the volcano
• Tray to contain the mess

Step 1: Build the volcano structure around the bottle with clay/playdough on the tray.

Step 2: Mix a few drops of dish soap, red food coloring, and about two tablespoons of baking soda inside the bottle.

Step 3: Pour vinegar into the bottle and watch the ‘lava’ erupt.

Science Project 2: Electromagnetic Crane

• Copper wire
• A large iron nail or bolt
• Small battery-operated DC motor (and batteries)
• Metal washer or paper clips (to lift)
• Tape or glue gun
• Sewing thread spool or pulley system
• Cardboard or wooden base for structure

Step 1: Wrap copper wire around the iron nail to create an electromagnet.

Step 2: Connect the ends of the wire to a battery to activate the magnet.

Step 3: Attach the electromagnet to the arm of your crane (which can be made from cardboard and attached to a motor).

Step 4: Use controls from the motor to move your crane and lift objects with the electromagnet.

Science Project 3: DNA Extraction from Strawberries

• Fresh strawberries
• Rubbing alcohol (chilled)
• Dishwashing soap
• Coffee filters or cheesecloth
• Glass cups or small beakers
• Bamboo skewers or toothpicks
• A plastic zip bag

Step 1: Mash strawberries in a plastic bag with a pinch of salt and a few milliliters of dish soap.

Step 2: Filter the mixture through a coffee filter into a glass cup.

Step 3: Slowly pour chilled rubbing alcohol into the cup without mixing. DNA strands will precipitate out and can be spooled onto bamboo skewers.

Science Project 4: Solar Oven

• Pizza box or similar cardboard box
• Aluminum foil
• Saran wrap or clear plastic window sheeting
• Newspaper for insulation
• Ruler and box cutter or scissors
• Non-stick cooking spray, black construction paper, and tape

Step 1: Cut a flap in the lid of the pizza box, leaving one edge intact. Cover the inside surface of this flap with aluminum foil.

Step 2: Line the inside of the box with black construction paper, and then place newspaper layers for insulation.

Step 3: Cover the opening from where you cut out the flap with saran wrap to create an airtight window for sunlight to enter but prevent heat from escaping.

Step 4: Place food inside, angle the foil-covered flap to reflect sunlight into the box, and cook.

Science Project 5: Homemade Barometer

• Empty tin can (around a liter in size)
• Ruler and scissors

Step 1: Cut the top of the tin can to open it completely. Stretch the balloon material over this opening, securing it tightly with tape to ensure it’s completely sealed.

Step 2: Tape the middle of the straw to the center of the balloon surface, ensuring it is straight and extends over the edge of the can.

Step 3: Position the index card behind the straw to act as a scale. Mark the initial position of the straw on the card with the marker.

Step 4: As the atmospheric pressure changes, it will affect the balloon surface, causing the straw to move up or down. Use the ruler to measure the straw’s movement and record the changes on the index card over time to track atmospheric pressure changes.

Science Project 6: Crystal Growth

• Salt or sugar
• Food coloring (optional)
• Clear glass
• Piece of string
• Pencil or paperclip

Step 1: Dissolve as much salt or sugar as possible in the hot water in the clear glass, stirring with the spoon. If desired, add food coloring to the solution.

Step 2: Tie one end of the string around the middle of the pencil and attach a paperclip to the other end as a weight. Place the pencil across the top of the glass so the string hangs into the solution without touching the bottom.

Step 3: As the water cools and evaporates, crystals will begin to form on the string. The process of crystal growth can take several days, during which the formation can be observed and recorded.

Science Project 7: Growing Bacteria Petri Dishes

• Agar (bacteria growth medium)
• Petri dishes
• Cotton swabs
• Incubator or warm spot

Science Project 8: Water Purification Experiment

• Dirty water (or tap water mixed with soil to simulate dirty water)
• Two glass jars
• Activated charcoal
• Cotton balls
• Stirring stick

Science Project 9: The Effect of Acids and Bases on Eggshells

Science project 10: building a simple electric motor.

• Insulated copper wire

Science Project 11: Homemade Compass

Science project 12: studying plant transpiration.
