Standard(s) Taught

SC.4.P.8.4 Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.
SC.4.P.8.2 Identify properties and common uses of water in each of its states.
SC.4.P.8.3 Explore the Law of Conservation of Mass by demonstrating that the mass of a whole object is always the same as the sum of the masses of its parts

MAFS.4.OA.1.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
MAFS.4.OA.1.2 Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
MAFS.4.OA.1.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Learning Targets and Learning Criteria

Students will:
investigate and classify objects that are attracted to magnets (paper clips, iron filings, scissors) and those that are not (bottles, pennies, nickels, copper wire, erasers, foil).
•investigate that all magnets, regardless of shape, have a north pole (N) and a south pole (S) although they may not be marked.
•investigate the presence of a magnetic field with different-shaped magnets.
•describe the effects of the magnetic field of different-shaped magnets using iron fillings.
•investigate how magnets attract and repel other magnets based on the presence of a magnetic field.

Students will:
•investigate and describe properties of water in all three states.
•identify common uses of water in all three states.
•explain the importance of water to life on Earth.

Students will:
•explore the Law of Conservation of Mass (whole = sum of its parts)to obtain the mass of various objects using tools and technology.
•demonstrate that the mass of a whole object is always equal to the sum of its parts.

Students will:
• interpret a basic multiplication equation as a comparison (e.g., if a = n × b, then a is n times as much as b).
• represent verbal statements of multiplicative comparison as multiplication equations.
distinguish multiplicative comparison (e.g., Tonya has 3 times as many cousins as Matthew) from additive comparison (e.g., Tonya has 3 more cousins than Matthew).
solve word problems involving multiplicative comparison.
An example would be: E.g., A red hat costs \$18 and a blue hat costs \$6. How many times as much as the blue hat does the red hat cost?
• solve multi-step word problems (up to 3 steps) that involve multiplication and/or division using strategies for this grade level
