What is the best way to present inferred data

I need Science Experiment ideas! I am in 8th grade and I have to do a Science experiment on whatever I want but I can't think of anything

The force that opposes the motion of one surface as it moves across another surface is referred to as

A resistor, an inductor, and a switch are all connected in series to an ideal battery of constant terminal voltage.

A girl throws a stone from a bridge. Consider the following ways she might throw the stone. The speed of the stone as it leaves her hand is the same in each case, and air resistance is negligible. Case A: Thrown straight up.

A pipe is subjected to a tension force of P = 50.00 kN. The pipe outside diameter is 32.00 mm, the wall thickness is 6.00 mm, and the elastic modulus is E = 150.00 GPa. Determine the normal strain in the pipe. Express the strain in mm/mm.

A 3 column table with 5 rows labeled table A. The first column is labeled voltage in volts with entries 1.0, 5.0, 10, 20, 50. The second column is labeled current: calculated in amps with no entries.

When you stack three flashlight batteries in the same direction, you get a voltage of 3*1.5 volts = 4.5 volts. What voltage do you get if one of the batteries is turned to face in the opposite direction? a) 0 volts b) 1.5 volts c) 3 volts d) - 4.

If an ant were scaled up to the size of an elephant, the ant would be

A 4.0 kg food pack was dropped from a height of 200 m by a helicopter during flood relief operations. At what velocity will the food pack be falling halfway to the ground?

The sun generates both mechanical and electromagnetic waves. Which statement about those waves is true? The mechanical waves reach Earth, while the electromagnetic waves do not.
